Today Cisco announced the the ASR 5500, the first new Cisco platform based on technology that Cisco got with its acquisition of Starent for $2.9 Billion in 2009. Following that acquisition Cisco rebrandedStarent's mobile gateway as the ASR500 in early 2010.
With the new ASR 5500, Cisco is providing a 10x improvement in performance and is targetting the platform to form the backbone of a service providers' elastic mobile packet core for wireless traffic.
Murali Nemani, director of service provider mobility at Cisco explained to InternetNews.comthat the ASR 5000 family of routers is the post office that routes all the mobile traffic through the network.
Kelly Ahuja, senior vice president and general manager in the Mobility Internet Technology Group at Cisco noted that the performance characteristics of the ASR 5500 span multiple areas. Ahuja explained that in the traditional router world, typically the key dimension is throughput. In contrast, when it comes to mobile, the challenges involve scaling to meet the number of user sessions and transactions per second as well as throughput.
"Throughput is driven by Shannon's Lawwhich is Bits per Hertz," Ahuja said. "So you can take all the traffic in a mobile network and aggregate down into smaller chunks, but the bigger thing is the sessions." Read More
