AbstractA segmental looking-up method for the line speed of IP routing features that the routing forward table terms are stored in a multi-segment storage. The higher terms are stored in CAM storage. Multiple segments are simultaneously look up. When the results from different segments are judged for output, the higher segment has high priority. Its advantages are high looking-up speed and higher performance of router.
