Abstract
Aspects of the present invention include multi-homed node in a port extender environment. In embodiments of the present invention, each port extender can communicate data traffic to the multi-homed node thereby increasing the number of available links to the multi-homed node. The communication with the multi-homed node is based on an identification associated with the data traffic.
Claims20
A multi-homed node information handling system in a port extender environment, comprising:
- a multi-homed node, configurable to connect to at least one port extender environment;
- a plurality of port extenders, coupled to the multi-homed node, each configurable to forward data traffic to the multi-homed node;
- a controlling bridge, coupled to the plurality of port extenders, that processes data traffic and receives data from and sends data to at least one of the plurality of port extenders;
- and
- at least one hash flow module that uses a hashing system to assign an identification to the data traffic.
2 more elements
A method for distribution of non-unicast data traffic to a multi-homed node in a port extender environment, comprising:
- using a controlling bridge to connect a plurality of port extenders and to forward data traffic to at least one of the plurality of port extenders;
- assigning an identification to the data traffic using a hash flow algorithm and
- selecting the port extender to be used to forward the data traffic based on the identification assigned.
A multi-homed node comprising:
- an ingress port configurable to receive data traffic forwarded by one of a plurality of port extenders, the port extender selected based on an identification associated with the data traffic;
- and
- an egress port configurable to forward data traffic to one of a plurality of port extenders.
