Abstract:

Aiming at solving the problem that no service-oriented bandwidth allocation strategy was deployed for mobile data service in core network,a service-oriented approach to bandwidth allocation based on GGSN was proposed.The approach achieved the service-oriented bandwidth allocation for mobile data service making use of the bandwidth demands of different services derived from the FBM traffic model and the G/D/1(n)queuing model,combined with the function of GGSN equipment and the situation of bandwidth resources.Theoretical analysis and simulation results indicate that the proposed approach can effectively classify the quality of different services and guarantee the bandwidth demands of high-value services.

Key words: mobile data service, bandwidth allocation, self-similarity, fractional brown motion
