Bandwidth Resource Dynamic Allocation in Differentiated Services Model
Diffserv中带宽代理BB的实现

To employ Differentiated Services, efficient and flexible resource allocation mechanism is needed. Static bandwidth resource allocation is not suitable for the situations in which traffic varies greatly with times. If customers bought bandwidth according to their highest traffic demands, some resource will be wasted when traffic load is light. On the other hand, the static allocated bandwidth may not satisfy the growing traffic demands. So it is necessary to allocate bandwidth resource in dynamic way. We bring up a prototype of BB, discussing the necessary components to realize the dynamic bandwidth resource allocation and further more, our BB can provides advanced reservation for bandwidth resource. Simulation tests show our design is feasible.
