An advanced data structure allows lookup based upon the most significant 16 bits and the following variable number of K bits of the IP destination address. This 16 / K scheme requires less than 2 MB memory to store the whole routing tables of present day backbone routers. A 16 / Kc version utilizes bitmaps to compress the table to less than 0.5 MB. For the 16 / K data structure each route lookup requires at most 2 memory accesses while the 16 / Kc requires at most 3 memory accesses. By configuring the processor properly and developing a few customized instructions to accelerate route lookup, one can achieve 85 million lookups per second (MLPS) in the typical case with the processor running at 200 MHz. Further, the lookup method can be implemented using pipelining techniques to perform three lookups for three incoming packets simultaneously. Using such techniques, 100 MLPS performance can be achieved.
