If the traditional packet matching algorithm is not able to be used in IPV6 environment

it must be of poor performance.This paper combines the real number coding differential evolution algorithm with the traditional packet matching algorithm

imports coefficient of variation in fitness value design and introduces distribution feature to adaptive adjust the acuteness degree of variation.Numerical experiments show that it has higher performance compared with the traditional ones.Package matching time performance has a weak correlation to the number of rule is another significant feature in the algorithm

so it is suitable for processing high peacekeeping large-scale package matching problem.Applying the algorithm to IPV6 network

the packet can linear speed forward.The proposed method is applicable to the firewall

router and other network equipment.
