Making sense of Service Provider Virtualization

I like to think of virtualization as an expanded networking toolkit, providing us with additional options to get the job done. It’s almost like when cordless tools entered the consumer tool market. You could take the cordless tools anywhere and use them in new and exciting applications. But there was a key drawback that I’m sure you remember. The early cordless tools had a limited effective power range. Over the next decade or two, battery technology improved and there were fewer power related drawbacks to going cordless.

A few similarities exist in the network functions virtualization (NFV) space. I Read More »

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 »

Join Cisco at the Light Reading Big Telecom Event in Chicago

dawoodWritten by Sultan Dawood, Marketing Manager

As SDN and NFV continue to be top of mind technologies for service providers, Light Reading is launching its first Big Telecom Event focused on bridging the gap in the telecom industry between technology know how and business acumen. In partnership with the Open Networking Forum (ONF), this event will comprises a conference with show floor demonstrations of networking technologies and applications that deliver real insight and tangible value to attendees. The BIG Telecom Event (BTE) will be a single big-tent event that aggregates all the hottest areas across our industry – including SDN/NFV and the carrier cloud, Ethernet, telco data centers, service orchestration, packet-optical transport, mobile backhaul, mobile network security, 4G/small cells, service provider IT, content management, and business services.

The event will be held in Chicago next week, June 17-18, 2014. Cisco will be Read More »
