Dynamic Inter-SLA Resource Sharing in Path-Oriented Differentiated Services Networks
Overview This paper proposes novel resource sharing schemes for Differentiated Services (DiffServ) networks, to achieve both high resource utilization and Quality of Service (QoS) guarantee. Service Level Agreements (SLAs) are negotiated at network boundaries and supported by path-oriented resource mapping within the network. In the bandwidth borrowing scheme proposed here, the dedicated bandwidth for underloaded SLAs is determined and adaptively adjusted at network boundaries according to the actual traffic load and QoS policies; the available spare capacity is then properly distributed to related links for lending to others. On the other hand, the traffic flows admitted with borrowed bandwidth are tagged and may be preempted later when the original bandwidth owner needs to claim back the resources.
