Abstract

The invention provides for 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), that have shown interest, to at least one receiver (24, 26), whereby in case of a link failure at least one of the at least one receiver (24, 26) sends back a message to the router.

Claims

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), that have shown interest, to at least one receiver (24, 26), whereby in case of a link failure at least one of the at least one receiver (24, 26) sends back a message to the router (14).

2. The method according to claim 1, whereby in case of a link failure the receiver (24, 26) noticing the failure will send a message back to the router (14) defining a path for the streams from the router (14) to the at least one receiver (24, 26).

3. The method according to claim 1, wherein in case of a link failure the switches (18, 20) in the network (10) will broadcast STP or RSTP messages to trigger all receivers (24, 26) to automatically send out a message.

4. The method according to claim 1, wherein the network (10) is a redundant Ethernet network.

8. The computer program with coding means, for carrying out all the steps of a process according to claim 1, wherein the computer program is run on a computer or a corresponding computing unit.

9. The computer program with program coding means which are stored on a computer readable data carrier, for carrying out all the steps of a process according to claim 1, wherein the computer program is run on a computer or a corresponding computing unit.

5. A computer network comprising a router (14) and a number of switches (18, 20) each having ports for receiving and sending messages and being connected to at least one receiver (24, 26), wherein the computer network (10) is adapted for sending messages from the router (14) via the ports of switches (18, 20), that have shown interest, to the at least one receiver (24, 26), whereby in case of a link failure at least one of the at least one receiver (24, 26) sends back a message to the router (14).

6. The computer network according to claim 5, wherein the computer network (10) is a redundant Ethernet network.

7. The computer network according to claim 5, wherein an Internet Group Management Protocol (IGMP) is used.
