| Abstract: | In order to solve the link problem when the link is shared by multi users under the condition of varying bandwidth, a hierarchical link sharing and bandwidth reallocation algorithm based on management territory for links with varying bandwidth is proposed. The link sharing framework is adjusted dynamically by testing the effective feedback bandwidth according to the output buffer in the algorithm. It can shield the first floor characteristics, and provides the absolute bandwidth and the fairness between territories and between classes. A lot of simulation experiments prove that the method is feasible and reasonable. |
| Keywords: | hierarchical link sharing class based queuing service quality link with varying bandwidth wireless link sharing bandwidth reallocation |
