Multimedia streams travel across a path that connects the source to the destination. This path should provide the multimedia streams with all required Quality of Services (QoS). Suppose that the determined multimedia path gives the multimedia streams all the needed services. Consequently; the multimedia streams flow in this path to reach the destination. In this situation, some sort of ambiguous question arises. The question is, what will be done if, during the multimedia streams flow in the path, that path is failed? This state causes a big problem especially when the multimedia streams are transported under the User Datagrame Protocol (UDP). This paper demonstrates the answer about the mentioned question by introducing analysis and design of a system that creates an alternative path in the case of original path failure. The proposed system considers the resulted network problems in the alternative path creation. Also, the paper introduces an implementation of the suggested system using a network simulator called NS2. Performance evaluation of the system also is demonstrated.
