As customers invest in WAN optimization, features and functions are getting more uniform across products. According to Infonetics analyst Matthias Machowinski, features like protocol optimization, caching of applications, bandwidth management, and compression, are fairly common across products from all suppliers. Less common is support for laptops and unconnected remote sites -- something that Citrix and Blue Coat offer in their optimizers, and which Riverbed has promised in a software client this summer.

There are indications that plenty more products and even companies are on the way. While WAN optimization progress is uneven, its momentum is unmistakable.
