Abstract
A first network node generates a message to be transmitted to a second network node. The message can include a value that identifies a type of the operational session, an identifier of the first network node that can control transmission of packets used during the operational session, and a length of the identifier. Further, the first and second network nodes can operate in an operational session in which the second network node can detect a failure.
Claims20
A packet communication method, comprising:
- starting, by a first network node, a timer, wherein the first network node and a second network node operate in an operational session that detects a continuity of path between the first network node and a second network node;
- receiving a packet by the first network node;
- performing a first determination that the packet includes a first Internet Protocol (IP) address that is the same as a second IP address of the second network node configured to control a transmission interval of packets;
- performing a second determination, by the first network node, that the packet includes a first identifier that is the same as a My Discriminator value of the second network node configured to control the transmission interval of the packets;
- and
- resetting, after the first determination and the second determination, the timer by the first network node.

A network node, comprising:
- a processor configured to:
- start a timer, wherein the network node and another network node are configured to operate in an operational session that detects a continuity of path between the network node and the another network node;
- receive a packet;
- perform a first determination that the packet includes a first Internet Protocol (IP) address that is the same as a second IP address of the another network node configured to control a transmission interval of packets;
- perform a second determination that the packet includes a first identifier that is the same as a My Discriminator value of the another network node configured to control the transmission interval of the packets;
- and
- reset, after the first determination and the second determination, the timer.
