- Abstract
- Networks tend to deliver delay-sensitive applications demanding deterministic end-to-end delay. A new framework is needed for this purpose as well as increase of network utilization. We propose a framework for absolute end-to-end delay guarantee composed of 3 main components including resource mediator, resource manager and ADRR scheduler. The resource mediator allocate end-to-end delay budget to associated networks. The resource manager located in a single network selects path for connection and apportions assigned delay to each node along the path. We propose DYNAMIC delay apportion policy which is allocating delay to nodes proportional to link loading status. By adoption ADRR in nodes of transport layer absolute delay is able to be guaranteed. We run simulation to compare the network performance of EVEN delay apportionment policy and DYNAMIC delay apportionment policy of resource manager. As a result, EVEN policy shows better performance in terms of end-to-end delay and end-to-end throughput.
