Alcatel-Lucent's EPC Breaks 100 Gbps Barrier in Ixia Test

Alcatel-Lucent's Evolved Packet Core (EPC) solution broke the 100 Gbps barrier for mobile gateway performance in a test performed with Ixia.


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.


"These test results show that aggregate speeds over 100 Gbps are today's reality for the Alcatel-Lucent LTE Evolved Packet Core gateways -- speeds that are necessary to accommodate the exponential rise of traffic in the mobile broadband evolution," said Kevin Macaluso, Vice President and General Manager of the Service Router product group within Alcatel-Lucent.


"LTE is about massive increase of video and data traffic which demands massive throughput in the Evolved Packet Core," said Victor Alston, Senior Vice President, Product Development at Ixia. "This collaboration with Alcatel-Lucent sets a new benchmark for LTE data plane processing and showcases the best practices in LTE service quality validation."http://www.ixiacom.com
