Abstract

Tasman Networks, Inc. commissioned The Tolly Group to evaluate its Tasman 1004 and Tasman 1002 wide-area network routers with integrated network services such as Quality of Service (QoS), IPSec VPN with on-board hardware acceleration, stateful firewall, Network Address Translation (NAT) and Access Control Lists (ACLs) for enterprises and service providers.

Tolly Group engineers measured the multilink Point-to-Point Protocol (MLPPP) zero-loss throughput of the Tasman 1004 router against Cisco 2811 and Cisco 2821 routers, with QoS, NAT and ACL features enabled in a scenario with multilink PPP traffic riding over four T1s.

To test IPSec VPN throughput over a single 3DES/SHA1 tunnel with QoS and stateful firewall enabled, engineers tested the Tasman 1002 against the Cisco 1841 and the Cisco 2811 for Layer 3 throughput with multilink PPP traffic riding over two T1s. The Tolly Group also tested the Layer 3 IPSec VPN throughput of the Tasman 1004 versus Cisco 2811 in a scenario with multilink PPP traffic riding over four T1s. All tests were performed in September/October 2005.
