NetScaler will provide network address translation to change the home-based IP address to another one associated with a local network. In addition, it will find the most economical Internet route for the traffic and will coordinate with content delivery networks (CDNs) so data is directed to the phone from the most nearby cache operated by the CDN, Bowman said. Using the NetScaler-Sandvine solution will eliminate all network latency except the delays caused by the radio access network, Bowman said.
Sandvine's EPC system will allow carriers to deliver the benefits of mobile IP offload selectively based on service plan, handset or application, Bowman said. The types of mobile data sessions that require a continuous connection, such as voice over IP calls, will not be offloaded from the traditional back-end network of the operator, he said. The NetScaler-based system is in trials and available now, the company said.
