Cisco Digital Network Architecture

Cisco Digital Network Architecture – An Overview of the Architecture Tools and Vision

Design principle #1: Security everywhere

Security is essential in any environment, public or commercial. With the recent threats of ransomware, including Not Petya and other hacks no extra explanation is needed. A secure network is critical for the security of the data that runs through the organization. By using the network as a sensor and enforcer (the network sees all flows), the network infrastructure can support in analysing the threats and risks to the organization. So the network must become a sensor and enforcer in the security framework. Of course the before-during-after paradigm for a security framework assists in this design guide as well.

Design principle #2: Virtualize everything

SDN has become common in many organizations, where the control plane is separated from the data plane (software defines how data flows through the network). SDN was always restricted to the type of hardware that is in place, e.g. a switch doesn’t have router functionality, a firewall is not a router, etc. What if you could virtualize these network functions in such a way so that the software defines what role the hardware has, without impact on performance (hardware asics)?

This means that a network component can fulfil different network functions during its lifecycle, being a switch, a firewall, a router, a WAAS or any new network function that is invented. Based on this design guide that all network functions are virtualized, an SDN controller can truly control the behaviour of the network infrastructure

Design principle #3: Designed for automation

Design the network in such a way that automation can take place. Automation is key to fast, standardized, delivery of changes across the infrastructure. This can only take place if the network infrastructure is standardized on software releases and configurations.
For example, only when the voice VLAN on all branch locations is the same, can a generic standardized policy (and assignment) be created for voice devices.

Design principle #4: Cloud service management

Cloud has become a common part of many IT environments. Cloud applications have very high availability and capacity. By using the cloud one can define and provision network services (applications, services) and policies (who is allowed to do what) from a central environment. Of course there is choice to run this centrally managed cloud app in a public cloud or on premise, depending on the organizations requirements and cloud maturity.

Design principle #5: Pervasive analytics

Machine Intelligence, big data lakes, and analysis of microflows help with the prediction of failures in your network. By proper analysis, problems in performance or behaviour can be predicted in a proactive manner. As an example, we all know that when a client cannot connect, it’s always the network. But with pervasive analytics, telemetry reports that the DHCP server isn’t responding back on the DHCP requests, so it is more a DHCP server problem. The average time to resolve a problem and find a root cause can be reduced dramatically because pervasive analytics provide you the insight. Perhaps this design guide could be the best part of the business case for DNA, imagination is only the limitation to what can be done.

Design principle #6: DNA-ready infrastructure

On the bottom is the infrastructure layer, consisting of all network components like your routers, switches, firewalls and wireless controllers. It doesn’t matter if the equipment is physical or virtual like ASAv, CRS1000V, or NGFWv.
The features of DNA (faster delivery of services, detecting problems and increasing flexibility) can only be implemented if your network devices are also DNA-ready. In fact, almost all actual switches, wireless components, firewalls and routers are DNA ready. Proper life cycle management is supportive for this.

DNA Framework

Principles alone do not create an architecture, it also needs a conceptual framework in which the different elements come together for the solution that meets the requirements (both technical and from the business) and the design principles. The network infrastructure communicates, via open API’s, with two processes:
• Automation is responsible for the so-called day0 (provisioning of new equipment) and day1 operations (create, change, update or delete of services). These API’s could be implemented in different ways, although more and more devices supported NETCONF and YANG models.The automation block can be filled with different kind of tools, for example APIC for ACI, Cisco NSO or APIC-EM for campus networks. It is dependent of the organisation itself.
Model, Tools and technology
A model is one step, but that doesn’t bring any company to a network infrastructure ready to adopt changes faster and become a more predictive less complex network. For that, Cisco has announced (and available) several products and solutions, that meet the above mentioned model. Below is a list of products from Cisco with a short explanation on its role within DNA.

DNA Center

DNA Center was announced at Cisco Live Las Vegas in June 2017. DNA Center is the single centralized management interface for Cisco’s Intent-based networking solution. It uses templates based on Cisco best practices and validated designs to enable the configuration of Cisco products and using network automation for solutions like software defined access (SDA). DNA Center is the integration of the blocks automation, analytics and centralized tool in a single appliance (DNA Center Appliance).

Cisco Enterprise Services Automation (ESA)

This is a separate application that communicates with APIC-EM (automation) to realise network function virtualizations on Cisco NFV platforms (ENCS5400, UCS-E series). It is used to define, deploy, and manage these virtual services on the platform. It is logical that in time this will also be featured in DNA Center.

Campus Fabric / Software Defined Access (SDA)

Software Defined Access is a (scalable) solution for campus networks to quickly, reliably and easily define new networks, including security and microsegmentations. It is based on a logical layer3 network infrastructure for connectivity (underlay) and clients are connecting to virtual networks based on VXLAN for data transport and LISP for control. As VLAN’s are not used anymore, time to deliver new services is cut down dramatically and problems with STP and VLAN’s are history as there is no layer2 network anymore.

Cisco Network Services Orchestrator (NSO)

Cisco NSO is a Network Services Orchestrator, also an automation tool. NSO is the result of the acquisition of tail-f in which the network infrastructure is based on a YANG model. On top of this YANG model services can be defined and deployed. So-called network endpoint devices (NED) take care of the translation from the YANG model with services to a configuration of the device. NSO is from the ISP world and is making its move to the enterprise however it doesn not currently support DNA Center. NSO is vendor-independent and there are also NED’s for other vendors like Citrix Netscaler, etc.

Cisco ISE

ISE is an integral part of the DNA framework, although it doesn’t fit in automation or analytics, as it provides both functions for device identity. ISE provides the identity services for your network and is used in Software-Defined Access (SD-Access) deployments to provide the SGT’s to the proper network port.

Enterprise Threat Analytics (ETA)

ETA is a newly announced analytics product that is capable of analysing behaviour of encrypted traffic in such a way that threats and other traffic can be detected without SSL decryption. It is used to determine if anomalies, like malware, are on your network or not.

Stealthwatch

Stealthwatch is clearly an analytics tool, which is used within the network as a sensor, based on Netflow. ETA and Stealthwatch are closely related with each other.

DNA Center Assurance

Assurance is also an analytics tool, in which telemetry is extracted from the network. CMX is an example, but DNA Center Assurance takes analytics much further, like detecting if the DHCP server isn’t responding to requests, or that a client is entering a black hole, or that your network is hitting a known caveat.

DNA-Ready Infrastructure Devices:

Almost all modern Cisco Switches, Routers, Firewalls, Wireless Controllers support DNA. Rule of thumbis that if the device has the UADP ASIC, it is DNA-ready and supports SD-Acesss. Most of these devices are Cisco IOS-XE based, like the Catalyst 3650/3850, ISR 4k and the WLC 5520’s. The new Catalyst 9000 has the new UADP 2.0 ASIC which enables it to support ETA.

How to wirelessly charge your iPhone 7

How to wirelessly charge your iPhone 7

Get iPhone 8 and iphone X features for your iPhone 7

The iPhone 8 family is the original of Apple telephones to help remote charging, something which has been a backbone in arrangements of potential iPhone highlights for the best piece of 10 years.



You can't just utilize Apple's own particular forthcoming remote accuse cushion of more seasoned iPhones, however. Too bad.

Be that as it may, there is an approach to make your iPhone 7 or iPhone 7 Plus remotely charge simply like an iPhone 8. All you require are two or three extras.

Kitting out with a collector

Initially, we require a case to get a remote charge flag. The AirPower innovation found in the iPhone 8 utilizes a particular chip that the iPhone 7 needs, and regardless of the possibility that it had one in the engine, the more seasoned iPhone's outline isn't reasonable for remote charging as standard.

Take a gander at different remote charging telephones and you'll see they either have plastic or glass backs, similar to the Samsung Galaxy S8. Metal backs like the iPhone 7's are not appropriate for current famous types of remote charging.

This is the reason we have to put the remote charging recipient between the telephone's back and the remote charging plate. It's typically finished with a case.

A standout amongst the most famous is the Mophie Charge Force case. This includes transmitters for both the Qi and PMA remote charging guidelines.

Know your gauges: Qi and PMA

Apple AirPower utilizes a custom rendition of Qi (articulated "chee"), as do the greater part of the prominent remote charge cushions. Be that as it may, one of the longest-standing players in remote charging, Powermat, utilizes PMA.

You can consider PMA and Qi as somewhat like VHS versus BetaMax or Blu-beam versus HD DVD. They're contending guidelines that intend to do generally a similar thing utilizing distinctive methods.

In case you're considering purchasing a more reasonable remote charging case for your iPhone 7 that backings only a solitary standard, we'd firmly suggest getting going to play a part with Qi as opposed to PMA.

While Starbucks utilizes PMA chargers in some of its stores (in the US), even it is beginning to receive Qi, on account of Apple's utilization of the standard in the iPhone 8 and iPhone X.

In the event that you need an option that is less expensive than the Mophie Charge Force you'll discover moderate Qi cushion choices online from organizations like YooTech and Antye. The Antye Qi recipient case is around a large portion of the cost of the Mophie elective.



There are even recipients that forget the case part, simply appending a 0.5mm thick board to the back of your telephone that interfaces with your iPhone 7's Lightning port. It's not the slickest look, but rather it limits mass, and most should work through a thin case.

For a definitive remote charging arrangement, search for a case that likewise has a battery worked in. By and by, Mophie offers an incredible arrangement with the Juice Pack Air.

It'll charge your iPhone's battery remotely first before energizing the additional 2,525mAh battery for the situation, which gives up to 27 hours' additional utilization. The main drawback is that a remote battery case will be more massive than a plain collector one.

Moto X4

MOTO X4

The Moto X4 is Motorola's combination Smartphone. Evaluated at $399.99 opened or $329.99 sponsored by Amazon advertisements, it joins angles from the two closures of its lineup, as double back camera sensors and a waterproof plan from the top of the line Z2 Force, with the midrange specs of the more moderate G5 Plus. It doesn't bolster Moto Mods, however has the practically stock Android programming Motorola is referred to for, and also joining with Amazon's Alexa voice associate. Its status is supported by a solid battery and strong double camera framework. Customers after premium highlights on a more unobtrusive spending will welcome the X4, our Editors' Choice in the midrange value section.

Design, Features, And Display 

The Moto X4 gets the attention. Its back board is intended to reflect light in various examples in view of edge and lighting conditions. It's very getting in both Super Black and Sterling Blue choices, however I saw it gets fingerprints and smircesh rather effortlessly and it's, exceptionally elusive.

The telephone measures a hand-accommodating 5.8 by 2.9 by 0.3 inches (HWD) and weighs 5.7 ounces. It's comparable in size to the G5 Plus (5.9 by 2.9 by 0.3 inches, 5.5 ounces), however its mirror-like outline looks and feels significantly more premium. This comes at the cost of weight however, as the X4 is about an ounce heavier than the HTC U11 Life (5.9 by 2.9 by 0.3 inches, 5 ounces).

There's a SIM/microSD card opening to finish everything, the last of which bolsters cards up to 2TB. What's more, there's an earphone jack on the base, alongside a USB-C charging port. Volume and power catches can be found on the right. There's a unique finger impression sensor on the base bezel and when you initiate One Button Navigation you can utilize a progression of swipe signals set up of the standard programming route keys. It's a clever component to spare some screen space.

Like the Z2 Force, the Moto X4 is IP68 waterproof, which means it can withstand submersion in six feet of water for up to 30 minutes.



The Moto X4 has a 5.2-inch, 1,920-by-1,080 IPS show. It's fresh, 424 pixels for each inch, coordinating the determination of the U11 Life. Hues are splendid and precise, and seeing edges are awesome. Brilliance increase truly well, and I could utilize the telephone outside without an excess of trouble. You likewise get all the standard Motorola highlights like Active Display, which illuminates the screen with time, date, warnings, and media controls when you lift the telephone up. Also, there are signal controls; contorting the telephone dispatches the camera and shaking it turns on the spotlight.

Processor and Battery 

The telephone is controlled by a Qualcomm Snapdragon 630 processor timed at 2.2GHz with 3GB of RAM. It scored 70,353 in the AnTuTu benchmark, which measures general framework execution, superior to the Snapdragon 625-controlled G5 Plus (63,845) and generally coordinating the HTC U11 Life (71,786). In standard use, this converts into quick, dependable execution with smooth multitasking. It can likewise deal with requesting diversions like GTA: San Andreas, however you may experience the incidental falter.

Camera 

The Moto X4 is the most recent telephone to join the pattern of double sensor cameras. On the back, you get one 12-megapixel essential sensor and a moment 8-megapixel wide-point camera. The two sensors give it an eminent favorable position over single-sensor gadgets with regards to centering rate and low-light execution, and bolster a full arrangement of manual controls to give you a chance to change things like white adjust and ISO.

Software

As far as programming, the telephone runs a genuinely stock adaptation of Android 7.1.1 Nougat with Motorola's helpful additional items empowered through the Moto application. A refresh to Android 8.0 Oreo should take off later on. Beside the previously mentioned motions, you can empower Moto Key, an approach to safely open Windows gadgets and sign into sites utilizing the telephone's unique finger impression sensor as verification. Setup is straightforward, however it expects you to download and introduce Moto Key programming onto your portable workstation or desktop and the X4 must be associated by means of Bluetooth.

vivo will grow to Europe and Africa in 2018 with Qualcomm's assistance

vivo will grow to Europe and Africa in 2018 with Qualcomm's assistance 

vivo is one of the best cell phone producers yet the brand isn't outstanding outside of its key markets – China and India. That will change one year from now as the organization ventures into Europe and Africa.


To reinforce its position, vivo marked a $4 billion reminder of comprehension with Qualcomm. This will involve specialized organization and patent sharing to offer 5G telephones for sale to the public and differentiate biometric verification highlights.

vivo was the first to do demo a unique mark preader beneath the show, yet the two organizations likewise need to create 3D facial distinguishing proof (think iPhone X), alongside filtering palm prints, iris checking and that's only the tip of the iceberg.

As of late, the organization propelled the X20 with Face Wake, vivo's facial acknowledgment (in light of the 12MP selfie camera), and Qualcomm's Snapdragon 660 chipset.


Kin organization Oppo and adversary Xiaomi marked comparable reminders with Qualcomm, pushing up the potential financial incentive up to $12 billion (which will be spread out more than 3 years). Oppo and Xiaomi are likewise keen on 3D filtering tech, which was supposedly co-created by Qualcomm and Himax (which influenced a urgent part in the Google To glass show).

Blue vivo V7+

Blue vivo V7+ arrives 

Two months back vivo V7+ appeared in two hues - Champagne Gold and Midnight Black. Today the organization reported a third shading choice of the telephone - Energetic Blue. 

As per the organization, the interesting shading choice "supplements the lively identity" of the youthful vivo clients. 

The Amazon India-restrictive V7+ in Energetic Blue will be accessible for pre-arrange between November 10 and November 14. One day after that the genuine deals start at the cost of INR21,990 (€286), which is the same as the other two shading variations. 

The vivo V7+ landed with a 24 MP forward looking camera and triple plate for two SIM cards and one microSD. The 18:9 proportion show is 5.99" in slanting and has a HD+ determination of 720 x 1440 pixels. 

Within, a Snapdragon 450 chipset is combined with 4 GB RAM and 64 GB inside capacity.

Why you should avoid your iPhone's calculator

Why you should avoid your iPhone's calculator

What does 1+2+3 equal? Not what you think, thanks to an iOS 11 bug. There's an easy fix, but it will annoy the hell out of you.

You expect a few bugs in a new operating system, but a busted calculator? That's... irritating.

But that's exactly the situation in iOS 11. When you rapidly add two or more numbers, Calc doesn't always register the third calculation press -- which could result in some serious mathematical errors.

Try it: Tap 1+2+3 in rapid succession. You'll very likely end up with 23 (or 24 if you proceed to tap "="), because that third "+" tap wasn't captured.

Why? There appears to be some "animation lag" at work: When you tap a number, it briefly lights up and then fades. But after the second number, if you try tapping a function (plus, minus, multiply, etc.) before the number has fully faded, it won't register.

The solution: slow down. Yeah, it's a crappy solution, but it does work.

There's anecdotal evidence this problem has existed since iOS 11 was in beta; my iPhone is running iOS 11.1. One of my CNET colleagues installed 11.2 (which itself is still in beta) and found that Calc seemed to be working better, but that the bug wasn't completely fixed. "Inconsistent at best," she said.More new..click here

Create and share Google Maps lists on the web from your desktop

Create and share Google Maps lists on the web from your desktop

This past February, Google made it possible to create lists of your favorite local spots in the Maps mobile app. A little later, the company added a sharing feature so you could send your lists to friends and family from your phone. 

Now Google is bringing the experience to your computer, as well.

Making it work on your PC is pretty simple. Just find a place on Google Maps via your favorite browser, click on Save, and add it to a new or existing list, which now sync across platforms. To see what you've saved to your lists, simply go to Your Places in Google Maps (mobile or web). If you want to share a list, all you need to do is tap or click on the three dots to find the feature. If you want to research and plan a trip, or just make a list of your favorite local hot spots, you're good to go — no matter the type of device you're on.

Cisco Multicloud

  Introducing Cisco Multicloud 

About everyone saw how Cisco could help with their private cloud and server farm needs, however few acknowledged how Cisco could fathom the difficulties they were looking in the general population cloud.



In all the cloud dialogs with both business and innovation pioneers, two key perspectives dependably rise

Organizations need to move to cloud at their own particular pace and with adaptability, regularly exchanging off between development speed and speculation assurance targets.

The new multicloud the truth is creating new necessities and making things more mind boggling than anticipated, and subsequently, they require straightforwardness to take full preferred standpoint of the cloud administrations they require, paying little respect to where they dwell.

Adaptability and effortlessness don't frequently go together well, and the cloud is no special case!

Truth be told, 94% of organizations moving to cloud say they will purchase administrations from various suppliers.

We've heard them boisterous and clear. They require help to address 4 noteworthy zones with consistency over each cloud they utilize.

In actuality, cloud suppliers can't resolve these issues over the multicloud world since they normally streamline for the utilization of their own condition, not for one of alternate mists.


That is precisely the part we are taking in the multicloud world!

Over the most recent year and a half, we have contributed vigorously to create and obtain new advances to address these multicloud needs.

We reported new energizing inward improvements, for example, ACI Anywhere and obtained incredible organizations like CliQr, OpenDNS, CloudLock, AppDynamics, and Viptela.


In all cases our north star has been the same – building multicloud programming abilities that work in any cloud condition, private or open.

The outcome is the business' driving multicloud enablement item portfolio.

A week ago the Cisco and Google Cloud association declaration showed how that item administration can convey adaptability and straightforwardness through an open mixture cloud condition.


In any case, there's progressively – while working with Google, we considered how to streamline the appropriation of our cloud portfolio, and we chose that Cisco Partner Summit was the correct time to act. The reason? Our accomplices confront that adaptability versus effortlessness exchange off each day as they address client needs, and in the event that we make it more straightforward for them, it will be less complex for our clients.


Today we're making the following move to execute our multicloud system by declaring the Cisco Multicloud Portfolio, which expands on our rich cloud item set and conveys a basic offer structure.

The new Portfolio firmly adjusts to our clients' needs. As they move to the multicloud world, they have to Connect, Protect and Consume cloud benefits reliably, regardless of where the cloud administrations live. Regularly their excursion begins with seeing how to construct or execute their cloud system, which requires the correct level of Advisory administrations.

Cisco empowers the multicloud world – whether you intend to develop your server farm to assemble a private cloud, stretch out your system to the cloud, include or construct new cloud benefits, or deal with the new multicloud condition. We meet you where you are. We enable you to move at your pace.
