Abstract
Various exemplary embodiments relate to a method of acknowledging a pseudowire (PW) status message by a PW node, the method including: receiving at the PW node a PW status message from a peer node; determining that acknowledging the PW status message will reduce the number of PW status messages sent by the peer node; and sending an acknowledgement message to the peer node acknowledging the receipt of the PW status message from the peer node.
Claims21
A method of acknowledging a pseudowire (PW) status message by a PW node, the method comprising:
- receiving at the PW node a PW status message from a peer node;
- determining that acknowledging the PW status message will reduce the number of PW status messages sent by the peer node;
- and
- sending an acknowledgement message to the peer node acknowledging the receipt of the PW status message from the peer node.
The method of claim Error! Reference source not found., wherein determining that the status of the peer node has changed includes determining PW status bits in the PW status message have changed.
The method of claim 10, wherein the specified interval of time is defined as a scale factor times a refresh timer interval, wherein the scale factor is predetermined.
A pseudowire (PW) node comprising:
- a network interface;
- a memory;
- and
- a processor in communication with the memory, the processor being configured to:
- receive at the PW node a PW status message from a peer node;
- determine that acknowledging the PW status message will reduce the number of PW status messages sent by the peer node;
- and
- send an acknowledgement message to the peer node acknowledging the receipt of the PW status message from the peer node.
A non-transitory machine-readable storage medium encoded with instructions for execution by a pseudowire (PW) node for acknowledging a pseudowire (PW) status message, the medium comprising:
- instructions for receiving at the PW node a PW status message from a peer node;
- instructions for determining that acknowledging the PW status message will reduce the number of PW status messages sent by the peer node;
- and
- instructions for sending an acknowledgement message to the peer node acknowledging the receipt of the PW status message from the peer node.
