Abstract:

The technical application of friendly worms is mitigated by a lot of impact when they spread on the network, But the main traffic comes from the scanning stage and the propagation stage.The SRF strategy is proposed,and the strategy can use the strategy of ordering, classification of IP addresses and the RRHl propagation at the scanning stage.Combining with the finite propagation and the frequency sensitive dynamic replication mechanism at the propagation stage and Comparing with the traditional ones, it decreases the traffic about 40 percent at the scanning stage.At the propagation stage,the strategy controls replication accurately, thus makes the traffic controllable.

Key words: friendly worm;spread strategy;finite propagation;dynamic replica control;SRF spread model
