A new approach to reducing delay jitter that uses multipath routing and redundant packets is described. Delay jitter causes data loss at the application layer and prevents the smooth provision of real-time multimedia communication services. In this paper, a policy of multipath routing for reducing delay jitter is discussed and an algorithm is proposed that solve the problem of selecting two paths for reducing delay jitter. The algorithm outputs a set of paths that satisfy a specified delay constraint; they share a few nodes and have a small delay difference. Simulation results showed that the set of paths is more suitable for reducing delay jitter than those selected using the routing method of a path diversity scheme.
