Ixia Breaks 100 Gbps Mobile Gateway Barrier
Ixia says that LTE Evolved Packet Core (EPC) test performed with Alcatel-Lucent broke the 100 Gbps barrier for mobile gateways. According to the company in this Market Watch release, this test paves the way for terabit capacities in the EPC for upcoming LTE network deployments.
"A set of two Alcatel-Lucent 7750 Service Routers, deployed in the role of LTE/EPC Serving Gateway and Packet Data Network (PDN) gateway, were stressed using Ixia's IxLoad application and Acceleron load modules and successfully passed multimedia traffic over simultaneous 80 Gbps downstream and 20 Gbps upstream links.
"Ixia IxLoad application and Acceleron load modules generated and tested a continuous flow of real-time traffic using more than 1.5 million active LTE connections (bearers) loaded at 65 Kbps each. This traffic, aggregated at more than 100 Gbps, was processed and passed across an Alcatel-Lucent EPC, which included two Alcatel-Lucent 7750 Service Routers. The scenario roughly equated to 1.5 million voice LTE channels or, inversely, more than 65,000 high-definition html-based H.264 video sessions running concurrently at aggregate speeds over 100 Gbps."
