Expand Networks Accelerator 4800 Series WAN Compression Evaluation versus Packeteer PacketShaper 2500 and Peribit Sequence Reducer-20

Abstract

Expand Networks, Inc. commissioned The Tolly Group to benchmark the effectiveness of the Expand Accelerator 4820 over other "next-generation" application acceleration solutions from Packeteer, Inc. and Peribit Corp.

Engineers measured the effective "acceleration" (compression) rates achieved by the Accelerator 4820 when processing a variety of standard data files. The Tolly Group also performed the same tests on a PacketShaper 2500, and a Peribit Sequence Reducer-20. Engineers subjected all three devices to a series of file transfer tests in which they had to use real-time compression techniques to move the Canterbury Files, a collection of large files, including the Bible, the first million digits of Pi, and the complete genome of the E. coli bacterium. In all, during each WAN compression test, 10 file transfers were conducted. Tests were conducted during September 2004.

Tests show that on both the compression and the time-to-transfer tests, the Expand Accelerator 4820 exceeded the capabilities of the Peribit and the Packeteer products tested. In fact, for compression tests, the Expand Accelerator 4820 delivered eight times more effective WAN capacity than the competitive products tested. And in time-to-transfer tests, the Expand Accelerator 4820 demonstrated that it is up to five times faster than the Peribit and the Packeteer offerings.
