Abstract
In a packet-based switch, a method for managing data flow between the switch and other switches that are interconnected in a mesh network. The method includes receiving at the switch a topology inform packet sent from a first switch of the other switches. The topology inform packet includes at least an identifier of the first switch. The method also includes updating a link state database associated with the first switch. The link state database is configured for storing topology data pertaining to the mesh network. The method further includes forwarding the topology inform packet to at least another switch of the other switches to enable at least another switch to update a link state database associated with at least another switch.
