Abstract
Some embodiments of the invention provide a WAN optimization method for optimizing traffic flows through a WAN connecting multiple sites each having at least one router. The method is performed in a kernel space of a first router at a first site. From a second router at a second site, the method receives, in an optimized data stream originating from a source device at the second site and destined to a destination device at the first site, a file including compressed segments not yet stored in a database of the first router. The method copies the compressed segments to a shared memory used with a decompression program operating in the first router's user space. For each compressed segment, the method receives, from the decompression program, a decompressed segment obtained by decompressing the compressed segment, and stores the decompressed segment in a kernel space memory for use in processing the file.
