Abstract
A system and method for determining route quality in a network in which multiple routes exist between a transmitting end-point and a receiving end-point. Initially, a routing sequence number is associated with each transmission sent on a route in the network, such that consecutive transmissions sent on one of the routes have consecutive routing sequence numbers. The routing sequence number for a first one of the routes is included in transmissions sent on a second one of the routes. The routing sequence number of the first route, received on the second route, is used as an indicator of the route quality of the first route, and this indicator is compared to an expected routing sequence number for the first route to determine a likelihood of whether the transmissions sent via the first route are either lost or delayed. The expected routing sequence number is normally incremented each time a transmission is received on the second route.
