Preserving Interflow Packet Order in Multipath Switching Systems Using Flow-Based Slicing For Congestion Avoidence

Congestion avoidance is an important traffic engineering task, which can be performed by making use of loadbalancing technique when a link is over loaded or failure of link occur in Multi-Path Switching Systems . Multipath Switching Systems are capable of transferring high rate data in networks. As preserving the inter flow packet orders while avoiding congestion is a major issue in consideration and previous packet based solutions require packet reordering which cause delay penalties. In this paper we use a flow-based slicing scheme which slits each flow in to slices at every interflow interval larger than the slicing threshold and balances the load to a finer granularity. We depict that flow-based slicing achieves inter flow packet ordering with little network cost while minimizing the packet out of order probability to negligible level comparatively less than 10.
