Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method in which a network switching device performs operations comprising: providing a tunnel keep-alive trigger message from a control processor of a network switching device to at least one forwarding engine of said network switching device, wherein said tunnel keep-alive trigger message includes a Multicast Group Identifier (MGID); producing, by said at least one of said forwarding engine of said network switching device, a tunnel…
