  • Method and system for sending return messages in MPLS networks
    Patent number: 7843924
    Abstract: A method for sending a message via a label switch telecommunications network, in particular an MPLS network. The method comprises identifying at a first router an input label attached to the message and using the first label to identify a output label that defines a forward path for the message. This is done by reading the label table in the router. Once the output label is identified, the input label is replaced with the output label and the message and the output label together are sent to another node of the network. When a return message is to be sent, input labels for the forward message path are used as output labels for the return message path.

  • Method and system for sending return messages in mpls networks
    Publication number: 20040174882
    Abstract: A method for sending a message via a label switch telecommunications network, in particular an MPLS network. The method comprises identifying at a first router (20) an input label (B) attached to the message and using the first label (B) to identify a output label (C) that defines a forward path for the message. This is done by reading the label table (28) in the router (20). Once the output label (C) is identified, the input label (B) is replaced with the output label (C) and the message and the output label (C) together are sent to another node (22) of the network. When a return message (32) is to be sent, input labels for the forward message path are used as output labels for the return message path (34).
