Extreme Networks Confirms Sub 50 Millisecond Ethernet Failover Capability

Tests conducted by BT's research, technology and IT operations business, BT Exact, have confirmed that Extreme Networks' Ethernet Automatic Protection Switching (EAPS) version 2 technology delivers sub 50-millisecond failover on both copper and fiber interfaces. Extreme said its performance is on par with Automatic Protection System (APS) for SONET/SDH-type network infrastructures, and surpasses the performance of the commonly deployed Spanning Tree Protocol (STP) and the Rapid Spanning Tree Protocol (RSTP) running on a switched infrastructure. The tests conducted by BT Exact were meant to verify the EAPS capability to perform protection switching of Layer 2 traffic in less than 50ms for up to 100 protected VLANs (virtual LANs), with each VLAN carrying 1,000 traffic flows. The tests also verified that Layer 3 traffic using BGP routing performed protection switching in less than one (1) second with 100,000 BGP routes advertised and up to 10,000 traffic flows. Notably, no BGP sessions were dropped during any of the tests. Extreme Networks has posted the results on its web site.
