When network segments get bogged down by excess traffic, the gut reaction of most IT managers and network administrators is to buy more bandwidth. However, adding bandwidth isn't always the answer. Sometimes, you can simply optimize WAN connections with better QoS or by using compression to streamline the traffic. Here's a look at some of the QoS and compression appliances that can optimize bandwidth and save your company money. There is also a direct comparison of appliances from Expand Networks and Packeteer, which author David Davis put to the test on a live network.
