Ethernet based networked audio systems becomes more popular within audio system designers. One of the most important issue that is available from networked audio system is the redundancy. The system can recover after different types of failures – cable or even device failure. Redundancy protocols implemented by audio developers are different than protocols known from computer networks, but both may be used in Ethernet based audio system. The most important attribute of redundancy in audio systems is a recovery time. The paper is a summary of research that was done at Wroclaw University of Technology. It shows the recovery time after different types of failures, with different network protocols implemented, for all possible network topologies in CobraNet and EtherSound systems.
