Patent ID: 8599680

Claim:
A method for configuring a virtual circuit set up between a first and a second terminal installation through which a data stream is intended to be transmitted, the virtual circuit being carried by an underlying path comprising a first link set up between the first terminal installation and an intermediate installation, a second link set up between the intermediate installation and the second terminal installation, and a third link set up between the intermediate installation and a third terminal installation, wherein the method comprises: a step of receiving a configuration message by the third terminal installation, said message comprising at least the following parameters: an identifying parameter for the virtual circuit, an identifying parameter for the underlying path carrying the virtual circuit, and a label determined by the first terminal installation, identifying the data stream; a step of configuring a switching table of the third terminal installation by using said parameters, and a step of processing the data stream by using the configured switching table, when the virtual circuit is switched from the second link to the third link following the detection of a fault on the second link.
