Abstract:

With the development of the next generation internet, the existing router architecture faces many problems,such as performance,complexity and power consumption. With the increase of the network size, how to implement a low-power MSF for IP lookup is a challenge in green and high-performance router designing. This paper represents an FIB multi-level mapping parallel multi-pipeline routing lookup architecture(FMML), with a dynamic routing table mapping algorithm designed to determine the optimal strides for building tree bitmap tries. Finally, experiments using real-life routing tables demonstrate that our solution can reduce 30% power consumption of routing lookup.

Key words: routing lookup, low power, multi-pipeline, green router, dynamic mapping
