  • BFD rate-limiting and automatic session activation
    Patent number: 7903548
    Abstract: A system and method for bidirectional forwarding detection (BFD) rate-limiting and automatic BFD session activation includes tracking a total bidirectional forwarding detection (BFD) packet rate for a line card (LC) of the node, and rejecting operations associated with creation of a new BFD session that would cause the total BFD packet rate to exceed a predetermined maximum rate. The new BFD session is stored in a state on the node and the operations of the new BFD session are automatically retried at a time when doing so would not exceed the predetermined maximum rate.
    Type: Grant
    Filed: January 28, 2009
    Date of Patent: March 8, 2011
    Assignee: Cisco Technology, Inc.
    Inventors: Reshad Rahman, David Toscano, David Ward, Jean-Marc Simard, Christian E. Hopps
