Abstract
A system and a method include a port extender communicatively linked to a controlling bridge. Network data is received from a local network peer downstream to the port extender. Whether a destination of the network data is a recognized downstream network peer of the port extender is determined. The network data is selectively routed according to whether the destination of the network data is a recognized downstream network peer of the port extender.
Claims20
A method comprising:
- in a port extender communicatively linked to a controlling bridge:
- receiving network data from a local network peer downstream to the port extender;
- determining whether a destination of the network data is a recognized downstream network peer of the port extender;
- and
- selectively routing the network data according to whether the destination of the network data is a recognized downstream network peer of the port extender.
2 more elements
A device comprising:
- a memory storing:
- satellite controlling bridge instructions;
- and
- a processor in communication with the memory, where the processor, when executing the satellite controlling bridge instructions, is operable to:
- receive network data from a source downstream network device;
- obtain a communication type determination specifying whether the network data comprises a unicast communication;
- obtain a destination recognition determination specifying whether a destination of the network data is a recognized downstream network peer;
- and
- selectively route the network data according to the communication type determination, destination recognition determination, or both.
6 more elements
A system comprising:
- a satellite controlling bridge in communication with an upstream master controlling bridge, a first downstream network device, and a second downstream network device, the satellite controlling bridge operable to:
- receive initial network traffic from the first downstream network device for delivery to the second downstream network device;
- forward the initial network traffic to the upstream master controlling bridge for routing;
- identify the first and second downstream network devices as recognized downstream network devices;
- and
- while the first and second downstream network devices are identified as recognized downstream network devices:
- receive subsequent network traffic from the first downstream device for delivery to the second downstream network device;
- and
- route the subsequent network traffic for delivery to the second downstream device without forwarding the subsequent network traffic to the master controlling bridge.
