Abstract

Tasman Networks, Inc. commissioned The Tolly Group to evaluate its Tasman 1004 router, a four port T1-based router and to compare its performance to four Cisco routers, the 1720, 1751, 2691 and 3725. The Tolly Group conducted tests to determine each device’s steady-state, zero-loss bi-directional throughput when transmitting data across multiple T1 connections. Tests were conducted across two and across four multi-linked PPP, aggregated T1 connections using a variety of Ethernet frame sizes with 100 sessions running and Quality of Service (QoS), Network Address Translation (NAT), Open Shortest Path First (OSPF) and Access Control Lists (ACL) services enabled.
