Like many organisations C4L’s network had gradually evolved over a number of years, but the demands of customers and the pace of change of technology meant that we were reaching the critical tipping point where something a little more radical and revolutionary than a SW upgrade was required. This was the dilemma that we faced a year ago, having grown and extended our all Cisco legacy network to the limits of what you might see as a very large Enterprise solution, where we really needed to be firmly in the Carrier space.

 

C4L is a Data Centre (DC) Infrastructure company at heart, we deliver Colocation, Cloud, Communications and of course Connectivity solutions allowing businesses to move critical systems to a DC and larger enterprises to expand and manage equipment over multiple sites. Our solutions are underpinned by our own private network, so performance, flexibility, scalability and reliability of the network is fundamental to our success.

5 Top Tips When Evaluating Your NFV Strategy

 

In the first part of my blog I talked through the lessons I had learnt from seeing my customers adopt both virtualisation and cloud technologies, and it got me thinking about how they apply these learnings to the latest virtualisation technology, Network Functions Virtualisation (NFV).

 

The acronyms "SDN" and "NFV" are as popular around our industry now as "cloud" and "virtualisation" was a couple of years back. We saw these ideas rapidly moved from a PowerPoint presentation to real life tangible benefits, and I believe the same is true here.

 

NFV was primarily formed by service providers looking at a way to reduce cost and increase agility whilst reducing the reliance they have on hardware vendors, therefore it has real momentum as the people who created it are the ones who will consume it.

 

Software Defined Network (SDN) has a broader remit and is, therefore, less well formed, but is potentially more significant in its potential impact to how you architect your network and applications.

 

Both SDN and NFV, however, should mean something to you and your business and they will undoubtedly transform it over the next five years.

We all like to consider ourselves independent spirits and most of us hate the notion that our behaviour can be mapped onto a process; that, in some way, we are predictable. Take two of my friends, they instinctively behave in different ways yet each trait can be identified as part of a proven process that leads to improved and more stable networks. I reveal all in the blog below.

Nature adapts, nature evolves, nature finds ways of improving itself. And history shows that if your species isn't in this group it will eventually die out. Well, you're thinking, this sounds like a doom-laden blog. But read on, nature - in the form of my cat - and and a man-made object - in the form of my garden wall - inspire some thinking that will give you a much improved network.

Over the last few years I have seen many of my customers transform their IT and businesses, as they grappled with emerging technologies, namely virtualisation and cloud. These concepts quickly moved from ideas to reality and I made some notes along the way. The lessons learnt from cloud and virtualisation can be applied to the latest technology trends in our industry and Part 2 of my blog will specifically apply these learnings to Software Defined Networks (SDN) and Network Functions Virtualisation (NFV). But first:

 

Lessons from Virtualisation and Cloud

 

1) Not everything is worth virtualising

 

Anywhere between 50% and 70% of all workloads today are virtualised, but that still leaves a large amount that are not. Often these are legacy applications that are not worth the hassle of virtualising, but many applications with high throughput or processing demands run better or need to be run on bare metal servers.

Keeping your network up and running is not unlike keeping your body up and running: you need to take steps to fix things when they go wrong, but you also need to make sure you are doing what is necessary to help you avoid them going wrong in the first place, or to get even healthier.

Building High-IQ networks with SDN and NFV

by Juniper Employee ‎07-09-2014 03:33 AM - edited ‎07-09-2014 03:39 AM

The elements of the Internet; network, compute and storage resources, come together to create a platform for innovation. It is a learning machine and so are we.  So can we draw inspiration about this platform from what we know about ourselves?

In our bodies we have both centralized and distributed intelligence. The software defined network paradigm follows this model. We centralize network intelligence where it makes sense, and distribute where it does not.

Service Providers: SDN and NFV an opportunity to innovate

by Juniper Employee ‎07-08-2014 05:01 AM - edited ‎07-15-2014 02:56 AM

In a recent event with press and analysts, hosted by Juniper, together with my colleague Nigel Oakley, I had the opportunity to discuss the state of the art SDN and NFV. During the workshop, we had the opportunity to describe the impact that virtualization has in the networking technology as well as the importance of SDN and NFV for the Service Provider strategy.

Stepping into an Intern's world at Juniper Networks

by Tom Creasey ‎07-07-2014 06:19 AM - edited ‎07-08-2014 06:50 AM

I am currently studying Enterprise Computing at the University of the West of England, Bristol. I am in my 3rd year (placement) and shall be starting to complete my 4th year in September 2014. Currently I am a Systems Engineer (SE) Intern for Juniper Networks, I am based in the UK.

 

Whilst being at Juniper Networks I have worked on various projects, such as Proof of Concepts (PoC’s) for customers and other SEs. This meant that I was allowed to work on some expensive, state of the art equipment, such as the new QFX series.

I feel that by having access to hands on equipment it allows me to get a better understanding and allows me to expand my knowledge to a higher level; I feel that this is not something that everyone gets to do. There is also a lot of responsibility within my role, for example, working with equipment that other colleagues are using for customer demonstrations. There have been many times where I have had to relocate the equipment or exchange it with something newer or different whilst making sure the functionality is kept for the current topology. I’ve also learnt about virtualisation and virtual machines; in the Addlestone lab we bought a Network Attached Storage (NAS) device, the idea was use it for cloud storage for all of our virtual machines and their data stores. This meant that there would then be better redundancy in place if there was a disk failure from any of the servers. Also we adopted this with the VMware products we had available; we had some vCenter licenses available for our VMware ESXi servers; this meant that we were able to connect these servers together which in turn gives us a single point of management, compared to managing each individual server. This permits us of doing vMotion, which allows the migration of virtual machines from one physical server to another with no down time.

During my time at Juniper I have also had the chance to work towards the JNCIAcertification that teaches you about JunOS and basic networking fundamentals; before I leave I will be certified. That will be another added bonus from my internship at Juniper.

Routers, switches and datacentres. The exciting life of an intern

by Leo Edwards ‎07-07-2014 06:18 AM - edited ‎07-08-2014 03:45 AM

This time last year I was informed that Juniper Networks was taking CVs and offering interviews to a select few students at my university for the chance of an internship over the following 12 months. I jumped at the opportunity and before I knew it I was talking routing protocols and future ambitions with my now line manager.

 

I managed to get one of the two positions on the UK intern programme, which I was to find was the first time to be undertaken in the UK. During the past 10 months  I have had a great chance to get to know how the networking industry functions, where my studies could take me and what my future holds in the networking world. I have built networks, constructed demos, attended customer meetings and experienced the day to day expectations of a Systems Engineer (SE) within Juniper. Sales could not be made possible without SEs and that means the company entirely relies on them.

Any IT & networking project follows three well-known stages: Plan, Build and Operate. Certain projects are part of the day-to-day activity of many organizations: adding a new rack of servers in a data-center, upgrading a cell-site to 4G or provisioning a new VPN in a network. The building phase of a new platform like SDN/NFV,  is not something you can take much risk.

The build phase of any project is always the most exciting. After what can seem an eternity of theortical practice in the planning stages it's great top get your hands on some new technology and start to cut it into your network. But it's also the most risky. Get it wrong and your customer experience degrades and your business can suffer. I comment on a new paper and video designed to help you prepare for, and get the most out of, the build phase of your next network project.

Roaming networks – the Achilles heel of security for mobile providers?

by Juniper Employee ‎06-27-2014 02:38 AM - edited ‎06-27-2014 02:38 AM

At the recent Hackinthebox security conference in Amsterdam, Dutch duo Stephen Kho and Rob Kuiters – who work for the Chief Information Security Office (CISO) team within the Netherlands largest telecommunications provider KPN – revealed that a significant percentage of nodes within the global set of GRX hub networks were accessible from the internet, and some of those were found to have applications running which exposed critical vulnerabilities.

Telecom Italia’s Flexible Service Chaining Proof of Concept

by Paolo_Fasano ‎06-26-2014 08:13 AM - edited ‎06-26-2014 08:14 AM

This is a guest blog post. Views expressed in this post are original thoughts posted by Paolo Fasano, Director, Network Innovation, Telecom Italia. These views are his own and in no way do they represent the views of the company he works for.

 

Within Telecom Italia domestic network infrastructure, the Service Point of Presence (POP) is the central office where subscriber management and other service functions are realized.  These functions include, among others, IP network termination, Authentication, Authorization and Accounting (AAA) proxy, security features, caches and content optimization, session borders controllers. The Service PoP is the key point in the network to apply network services to traffic flows based on customer categories, customer profiles or user applications.

 

The evolution of this strategic part of the network follows specific improvement targets.

 

First of all, the need for efficiency: there is an opportunity to share the same network functions among all customer categories, by realizing a common switching infrastructure. This has been the driver for introducing the Juniper Networks MX Series as the switching platform called “Service Hub” to aggregate all different Edge nodes and dedicated service nodes.
