Application of Markov Decision Process in Scheduling Algorithm on Concurrent Multipath Redundancy Transmission
Traditional network terminal equipment is usually connected to a single path network,so when an exception occurs in the path usually seriously affect the data transmission quality.With the development of overlay network and heterogeneous multi-access networks,concurrent multi-path transmission has become possible.The scheduling algorithm for multi-path transmission is the core issue of the recently research.This paper presents a Markov Decision Process based scheduling algorithm on concurrent multi-path redundant transmission which divides a transmission into several steady-state strategy of Markov process to make a decision and transmit key data redundantly in other path.It fulfills the requirements of real-time transmission and improves data transmission reliability.Simulation results show that the scheduling algorithm can correctly perceive the changes and dispatch more data to the path of better quality when the path transmission quality changes and effectively reduce the impact of the transmission when path quality deteriorates.The algorithm can be applied to audio,video and other real-time services,which will effectively improve the user experience.
