Tolly and Ixia Tested: System Resiliency and QoS at
Terabit Traffic Loads

Force10 Networks, Inc. commissioned The Tolly Group to evaluate its TeraScale E-Series E1200 Resilient Switch/Router, a chassis-based system with 14 line-card slots, plus built-in redundancy and resiliency features.

Test highlights

• Supports 100% of line-rate zero-loss throughput when tested across 56 10-Gigabit Ethernet ports during a Switch Fabric Module failover, while passing over 1 Terabits per second of traffic.
• Recovers from link outages in less than 2 milliseconds with a single Layer 2 flow, and less than 1 millisecond with 16 million Layer 3 flows, both well below the failover time usually reserved for SONTET/SDH links.
• Maintains all BGP, OSPF and Telnet sessions even when hammered by a multiheaded Denial of Service attack.
• Relies upon QoS facilities to ensure voice, video and data traffic types are handled according to policy parameters and with respect to latency sensitivity.
• Scales to support service provider-class peers, handling more than 1,500 BGP peers and 6 million paths.
