Latest Patents
Subhash Suri holds a patent for "Fast scalable methods and devices for layer four switching." This patent describes methods and devices designed for layer four switching in routers, which are essential for Internet functionality. The first method involves constructing a grid of tries, which are binary branching trees, from a set of routing filters. This grid includes a destination trie and several source tries, ensuring that each filter is stored in only one trie to prevent memory blowup. The methods also utilize switch pointers to improve search costs and may incorporate hash tables for handling combinations of port and protocol fields. Additionally, a hashing-based method is described, which searches for the lowest cost matching filters in bit length tuple space. Various optimizations are provided to enhance the performance of these methods, making routers capable of rapid and selective data packet switching, particularly suited for Internet Protocol networks.
