Mechanism for updating the parameters of a pseudowire

A router that is part of a packet-switched network, said router including:

• means for transmitting data over a pseudowire set up between said router and a second router that is part of said packet-switched network, said data being transmitted in accordance with a parameter of said pseudowire;
• and
• means for sending the second router a modification request message of the parameter of said pseudowire.

A router that is part of a packet-switched network, said router including:

• means for transmitting data over a pseudowire set up between said router and a first router that is part of said packet-switched network, said data being transmitted in accordance with a parameter of said pseudowire;
• and
• means for receiving a modification request message of the parameter of said pseudowire sent over said pseudowire and means for modifying the parameter of said pseudowire.

A computer program product stored on a computer-readable medium and/or executable by a processor, wherein the product includes program code instructions for executing a method of communication between first and second routers, said routers being part of a packet-switched network, when said program is executed by a computer, said method including:

• a stage of transmitting data over a pseudowire set up between the first and second routers, said data being transmitted in accordance with a parameter of said pseudowire;
• and
• at least one step of sending a modification request message of said parameter of said pseudowire at the initiative of one of the two routers, to the other router, and during the stage of transmission over the pseudowire.

A method comprising:

• generating a signal that carries a modification request message of at least one parameter of a pseudowire set up between a first router and a second router, said first and second routers being part of a packet-switched network;
• and
• transmitting said signal over the pseudowire.
