Abstract
A system and method can support multi-homed routing in a network environment, which can be based on InfiniBand architecture using a fat-tree or a similar topology. The system can provide an end node that is associated with a switch port on a leaf switch in a network fabric. Then, the system can perform routing for each of a plurality of ports on the end node, and ensure that the plurality of ports on the end node take mutually independent paths.
Claims20
A method for supporting multi-homed routing in a network environment, comprising:
- providing an end node that is associated with a switch port on a leaf switch in a network fabric, wherein the end node is associated with a plurality of ports;
- performing routing for each said port on the end node;
- and
- ensuring the plurality of ports on the end node taking mutually independent paths.
A system for supporting multi-homed routing in a network environment, comprising:
- one or more microprocessors,
- a subnet manager running on the one or more microprocessors, wherein the subnet manager operates to
- associate an end node with a switch port on a leaf switch in a network fabric, wherein the end node is associated with a plurality of ports;
- perform routing for each said port on the end node;
- and
- ensure the plurality of ports on the end node taking mutually independent paths.
A non-transitory machine readable storage medium having instructions stored thereon that when executed cause a system to perform the steps comprising:
- providing an end node that is associated with a switch port on a leaf switch in a network fabric, wherein the end node is associated with a plurality of ports;
- performing routing for each said port on the end node;
- and
- ensuring the plurality of ports on the end node taking mutually independent paths.
