Abstract

Tasman Networks, Inc. commissioned The Tolly Group to evaluate its Converged Services Router 3120, a wide-area network router with integrated network services such as Quality of Service, Network Address Translation and Access Control Lists.

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 a Cisco Systems 3825 Integrated Services Router and 2821 Integrated Services Router. Testing was performed in September/October 2005.

Test results show that the Tasman 3120 delivers superior throughput for the majority of packet sizes tested, especially with regards to smaller packet sizes (64 bytes to 256 bytes), generally delivering up to 4X greater throughput than the Cisco devices tested.
