Abstract
Systems and methods may be provided embodying an optimized Trill LAN network hello mode. The optimized hello mode may allow the number of LAN hellos exchanged to be reduced significantly in a steady state mode of operation. No modifications to the current Trill specification are needed and in a converged state (when designated RBridge election and appointed forwarder appointments are complete), only 1 hello PDU per RBridge is originated in every hello interval.
Claims20
A method comprising:
- achieving steady state converged operation on a Trill LAN network;
- and
- entering a plurality of nodes into an optimized hello mode, wherein optimized hello mode requires that the plurality of nodes only send hellos on a currently designated vlan and that no appointed forwarder inhibition hellos are exchanged.
A Trill LAN network node comprising:
- a memory;
- and
- a processor coupled to the memory, wherein the processor is operative to:
- enter the network node into an optimized hello mode;
- and
- exit the network node from the optimized hello mode upon detection of predetermined conditions.
3 more elements
A method comprising:
- entering a plurality of Trill LAN network nodes into an optimized hello mode;
- detecting the failure of one of the plurality of network nodes;
- and
- responding to the network node failure based on the role of the network node.
