A bandwidth reservation service provides paths to users when they need. The paths are set satisfying their requirements. By this service, users make a bandwidth reservation according to their plans. In order to provide limited network resource effectively, there are some methods to assign bandwidth to each service. However, these bandwidth assignment schemes are not perfect, and some other techniques are necessary to avoid user request blocking. In this paper, we evaluate bandwidth assignment schemes qualitatively and propose a heuristic routing and reservation algorithm. Key ideas is, first, calculating some route-rearrange targets only when a newly requested path competes against paths in service or reserved for future use, and to route-rearrange competing path routes, or route-rearrange targets, if necessarily. Additionally, the route-rearrange is executed within users’ QoS are satisfied. This leads to provide users’ QoS as requested, increase network resource utilization, and minimize path routes changes that are in service. Numerical results indicate that route-rearrange of only a few paths improve 50 % of request acceptance success rate. |
