Routing of data packets from source to destination is the primary function of Network layer. If a single path is chosen for data transfer from source to destination, congestion and packet transfer delay increases. In order to minimize this problem, multi-path routing protocol is preferred. There are many multipath routing techniques available; such as SMPC, SMPC-I, SMPC-P. In multi-path routing, not all the paths may have the same capacity, and then there is every possibility of occurrence of congestion at a router in the path.The proposed method provides a better solution for minimizing the congestion by rerouting the data packets over other paths, which are not utilized by the same in multi-path routing. This method avoids the unnecessary dropping of packets at a congested router and improves the network performance.
This paper proposes a new queuing technique in Adaptive Multi-Path routing based on packet priority. Simultaneous Multi-Path routing is used to improve the data performance over a congested network. The traditional method of transmitting the data is done by using Simultaneous Multi Path Communication (SMPC). Two types of SMPCs are proposed, in which SMPC-I, which uses multiple paths independently and SMPC-P, which uses path priority control algorithm in conjunction with SMPC. SMPC-I and SMPC-P maintains throughput regardless of path length and priority control. In addition to available SMPC methods, proposed method provides better solution to improve the performance of communication network. A theoretical approach of AMPC-PP proposed here based on packet priority for important data over normal data on a congestion network with route adaptability.
