Abstract:

Network flow identification and management play an important role in network application. However, with the rapid growth of network link speed, the fl ow management becomes more and more difficult. Hashing algorithms have very high performance because of its constant search time and the smaller storage  overhead. In the paper,we first define some access performance metrics which are concerned by flow management applications; and then prove the proposed  CRC20 algorithm has better performance in computing and memory accessing,and is suitable for flow management applications in highspeed networks.

Key words: flow management;Hash algorithm, network security, CRC algorithm
