In this Letter the bandwidth resource allocation strategy is considered for traffic systems of complex networks With a finite resource of bandwidth an allocation strategy with preference parameter alpha is proposed considering the links importance The performance of bandwidth allocation strategy is studied for the local routing protocol and the shortest path protocol When important links are slightly favored in the bandwidth allocation the system can achieve the optimal traffic performance for the two routing protocols For the shortest path protocol we also give a method to estimate the network traffic capacity theoretically (C) 2010 Elsevier B V All rights reserved
