Abstract:
1. A method for using a computer network ( 10 ) comprising a number of switches ( 18 , 20 ) each having ports for receiving and sending streams, wherein the streams are sent from a router ( 14 ) via the ports of switches ( 18 , 20 ) to at least one receiver ( 24 , 26 ), whereby in case of a link failure where an application running on a receiver ( 24 , 26 ) detects the streams have suddenly stopped, the receiver ( 24 , 26 ) sends back a message to the router ( 14 ) by a network path different than the network path having the link failure; wherein the receiver ( 24 , 26 ) detecting the failure sends an Internet Group Management Protocol (IGMP) message back to the router ( 14 ) defining a new path for the streams from the router ( 14 ) to the receiver ( 24 , 26 ); and wherein the receiver ( 24 , 26 ) begins to receive the streams again in less than 100 milliseconds.
