Abstract

Tasman Networks, Inc. commissioned The Tolly Group to evaluate a trio of its wide-area routers: the Converged Services Router 3120, Tasman 1004 and Tasman 1002, wide-area network routers with integrated network services such as Quality of Service, IPSec VPN with on-board hardware acceleration, stateful firewall, Network Address Translation and Access Control Lists for enterprises and service providers.

Tolly Group engineers measured the multilink Point-to-Point Protocol (PPP) zero-loss throughput of the Tasman 3120 with Quality of Service (QoS), Network Address Translation (NAT) and Access Control List (ACL) features enabled. Tasman Networks also directed The Tolly Group to evaluate the Tasman 3120 versus an ADTRAN NetVanta 4305 in a scenario with multilink PPP traffic riding over eight simulated T1s.

Test results show that the Tasman 3120, 1004 and 1002 deliver superior throughput for the majority of packet sizes tested, especially with regards to smaller packet sizes (64 bytes to 256 bytes), generally delivering from 2X to 7X greater throughput than the ADTRAN devices tested.
