How Important are Physical Routers in the move toward Virtualization?

How important are physical routers in the move toward virtualization?

My one word response would be “very”. But the longer version would start with “it depends”.

Here’s the longer version:

It depends on your perspective. I remember when the Cisco 12000 Series GSR was introduced in the late 90’s. It started an arms race that would last for over a decade. The popular comparison at the time was all about who had the biggest router, or “speeds and feeds” as we used to describe them. 2015 offers us a very different networking discussion. People that design and operate networks are more interested in programmability and virtualization (a.k.a. SDN (Software Defined Networks) and NFV(Network Functions Virtualization). From Frederic Trate’s blog on Application Engineered Routing, you can see why this level of control is such an interesting and important place to start the discussion.

I would argue that in terms of talking points, “speeds and feeds” have taken a back seat in network design. After all, a bunch of static ports and traffic-engineered tunnels don’t lead us to the flexibility and scale that we all seek – or can they? Here are some instances where physical routers are still Read More »

Making Applications and Network Infrastructure Talk

Frederic TrateGuest blog by Frederic Trate, SP Product and Solutions Marketing

One may say this is a topic the telecom industry has been working on for many years and that’s somewhat true. Remember the time when routing protocols and QoS (Quality of Service) mechanisms were the only tools at Service Provider’s disposal to arbitrate between sensitive and non-sensitive traffic? That worked pretty well as long as Service Providers only had to support a few applications – mainly voice and data.

Over time however, as carriers began to converge networks assets into a single, unified IP infrastructure they were faced with the challenge of increasing control over their network infrastructure. Programmability was not yet an industry buzzword but Read More »

RST Fiber’s High-speed Network powered by Cisco’s Evolved Programmable Network

ginaBy Gina Nienaber, Marketing Manager

We’ve been discussing the Evolved Programmable Network for some time now, knowing the transition from an IP NGN to an EPN is not something that will happen overnight (See EPN Blogs 1 , 2, 3). The Cisco® Evolved Programmable Network (EPN), represents an idea, an end-to-end unification of network, storage, and compute elements, and a lofty concept for existing multivendor networks to aspire to. New entrants into the communications industry are capitalizing on this period of evolution by building homogeneous end-to-end networks purpose built for SDN and NFV innovation.

One recent entrant is RST Fiber, based in North Carolina. Earlier in the year, Cisco and RST announced their 100 Gbps network deployment covering over 3000 miles throughout North Carolina with plans to Read More »

Cisco Continues Market Share Leadership in Mobility – First in Mobile IP Infrastructure, Packet Core, Mobile Backhaul, and Mobile IP Core

Over the summer, we shared with you the results of an ACG Report showing Cisco as the market share leader in Mobility.

Then and today the usage of mobile devices has been on the rise. Unequivocally.

The average smartphone user is accessing 26.8 apps every month for about 30.25 hours, an increase of 65 percent from two years ago. On their first weekend of offering the iPhone 6, Apple sold more than 10 Million units. Global smartphone market is forecasted to rise by around 20% to 1.2 billion units during 2014.

ACG Research came out with a new report recently the highlights of which I want to share with you. In this report Ray Mota notes that the Worldwide Mobile IP Infrastructure Market continues to rebound in Q2, 2014. It actually grew in Q2, increasing to $1.25 billion, a 9.6 percent quarter over quarter. Evolved Packet Core (MME, PGW, SGW, and PCRF) also grew this quarter to $123 million, a 7.2 per cent quarter over quarter.

ACG Research maintains its views that online video continues to fuel mobile data traffic and the industry expects a tenfold increase in five years.  Mobile spending continues and is increasing globally as carriers in developed countries vie for top billing for fastest carrier, fueling LTE spending. 3G remains strong and continues to grow as developing economies upgrade and invest in this technology. Mobile infrastructure will continue to be a highly dynamic market for the next several years as vendors and carriers work through new technologies.

Cisco maintains its position of market share leader. The Read More »

Good News Keep Coming on the Mobility Front

Recently I shared with you an ACG Research report which shows Cisco leading in Mobile IP Infrastructure and gaining market share.

Now step with me into the future for a moment and picture this.

2018 – nearly 21 billion globally networked devices and connections are live, 7.3 billion M2M are online, four billion global Internet users are connected, and IP video  represents 79 percent of all Internet traffic. According to a recent Cisco Visual Networking Index study, this is a mere glimpse of the future. And who is at the heart of enabling all of this? You’re right, mobile service providers.

The next thing you will want to know is what puts them in this sweet spot. Capturing  the opportunities afforded by everything going mobile is not easy. Yet service providers alerted at this high-stakes business promise of the future are racing to set themselves up with the means to leverage it. They are employing an architectural approach to their networks that will allow them a couple of things; apply Read More »
