  • Tunnel keep-alive timeout mechanism based on quality of service (QoS) value of received keep-alive messages
    Patent number: 9338066
    Abstract: A method, apparatus and computer program product for providing a variable tunnel keep-alive interval is presented. A tunnel keep-alive packet for a first tunnel is received at a first switching device. A Quality of Service (QoS) value of the keep-alive packet ishcekce. A determination is made regarding whether the QoS value corresponds to a QoS value of network control traffic, and when the QoS value of the keep-alive packet is lower than the QoS value of the network control traffic then a value of a tunnel keep-alive interval is increased.
    Type: Grant

  • Mechanism for efficiently transmitting tunnel keep-alive messages
    Patent number: 8929370
    Abstract: A method, apparatus and computer program product for efficiently transmitting tunnel keep-alive messages is presented. A tunnel keep-alive trigger message is provided from a control processor of a multi-processor network switching device to at least one forwarding engine of the network switching device. The at least one of the forwarding engines produces a tunnel keep-alive packet as a result of receiving the tunnel keep-alive trigger message from the control processor. The at least one forwarding engine forwards the tunnel keep-alive packet on all tunnels the forwarding engine is servicing.
