Configuring Multiple Layer 1 Crossbar Chips

원문 (중국어)

Electrical paths between ports (interfaces) of a network device are provided using an arrangement of interconnected Layer 1 (L1) crossbar switches in the network device. The network device includes internal data tables, e.g., a reachability table and a plurality of Layer 1 forwarding tables. These data tables are generated from a description of the crossbar chips in the network device. Heuristics are used to define one or more paths through the crossbar switches to connect between user-specified ports on the network device. The heuristics can select paths between ports based on criteria such a lowest latency, path stability (i.e., minimizing disruption to existing paths), and the like. The heuristic can be driven by a user who specifies via a CLI one or more crossbar switches on the path between the specified ports.
