Original Abstract Submitted
Some embodiments of the invention provide a WAN optimization method for optimizing traffic flows through a WAN. 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 from a second site source device to a first site destination device, a file including compressed segments not yet stored by the first router, and copies the compressed segments to a memory shared with a decompression program in the first router's user space. For each compressed segment, the method receives a notification that a decompressed segment obtained by decompressing the compressed segment has been written to a disk storage of the first router, the notification including a block address for the decompressed segment, and updates a cache of the first router with an entry mapping the decompressed segment to the block address.
