Abstract
A system, apparatus, and method selectively provides content compression to a client based, in part, on whether the network connection from the client is determined to be a high latency, low-bandwidth connection. The present invention gathers one or more network metrics associated with the connection from the client. In one embodiment, the metrics include estimated TCP metrics, including smoothed round trip time, maximum segment size (MSS), and bandwidth delay product (BWDP). These estimated network metrics are employed to make an application layer decision of whether the client connection is a high latency, low-bandwidth connection. If it is, then content may be selectively compressed virtually on the fly for transfer over the network connection. In one embodiment, the selective compression uses a content encoding compression feature of the HTTP protocol standard.
