Distributed routing table system with improved support for multiple network topologies

摘要

Generally, this disclosure provides systems, methods and computer readable media for switching systems employing distributed routing tables to provide improved support for multiple network topologies, configurations and routing modes. A routing system of a switch, for routing a packet from an input port of a switch to an output port, may include memory modules to store routing tables configured to store entries, each entry configured to store output port identifiers. The routing system may also include a table address generation module configured to select an entry from the routing tables based in part on a first subset of a Destination Location ID (DLID) associated with the packet. The table address generation module may further be configured to select one or more output ports from the selected entries, the selected output ports based in part on a second subset of the DLID.
