Abstract

A method and apparatus for dynamic network link acceleration provides a managed communication link for accelerated and reliable network communication between a client and other network devices. In one or more embodiments, a client computing device which generates communication packets of a first type is enhanced with a front end mechanism which selectively encodes the data packets into packets of a second type. The data packets which are encoded into a second type are transmitted over a managed communication link which may provide error correction, security, quality of service, and other services including acceleration of communications.
