100GE – A TOOL FOR MAKING THE UNPREDICTABLE PREDICTABLE

by Juniper Employee on ‎06-08-2009 09:24 AM

I wouldn't say I was startled when first briefed by customers on their 100GE requirements in early 2006, because I knew the topic was on the agenda-but I was given pause by the perceived urgency of it. In core routing, we are used to traffic growth rates of 70-80%, and a network architect planning for this kind of growth has to consider all kinds of tools to cope with this possibility. 

 

Distributed solutions with 10 GE and 10 or 40 Gbps SONET were the options of the day (funny to be talking about "the old days" of 3 years ago!). At the same time, the demands on the networks for increased reliability increased, and the need to continue to scale at higher speeds did not go away. Then with 3G, a new requirement emerged for a single, ubiquitous network that was simple, uniform and convenient, whether accessed from a MAC, a PC, a blackberry, a netbook....inasmuch as possible, all the same services are sought.

 

The distributed model scaled well but the operational costs were very high. Management and security quickly became big challenges across far flung geography and we have continued to hear the phrase "too many POPs" throughout the last several years - and recently I am hearing very aggressive plans to reduce presence locations by factors of 4 or more.

 

With cloud computing, the same trend is of occurring with data centers, and new services such as Verizon's CaaS speak directly to the requirement to increase and throttle computing power and bandwidth in tandem - placing heretofore unseen flexibility demands on networks and creating what our Marketing VP Luc Ceuppens calls the "networked data center."  

 

In addressing these trends, customers are working with us to virtualize their infrastructure, as part of the plan to ensure full consolidation, we have produced larger routing nodes to scale this virtualization.  This is working well and will offer the scale and reliability needed, and, predictably, it leads us back to the need for higher speed interfaces.

 

And that's why we announced our 100GE offering on Monday. Higher speed links are a vital tool to make today's networks more responsive to emerging demands. Happily, Juniper is able to leverage our 100Gbps/slot capacity to be the first to address the next generation of higher speed Ethernet.
