Abstract: A computer-implemented method for load balancing multicast traffic may include (1) identifying a plurality of switches that include at least a first switch that is connected to a second switch by a first path and a second path, (2) calculating a plurality of multicast distribution trees for distributing multicast traffic among the plurality of switches that includes (i) a first tree that includes the first path and whose root is different than the root of a second tree and (ii) the second tree that includes the second path, (3) receiving a plurality of multicast packets ingress to the plurality of switches at the first switch, and (4) using at least two of the plurality of multicast distribution trees to transmit the plurality of multicast packets from the first switch to the second switch. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A computer-implemented method for multipath load balancing may include (1) identifying a plurality of paths from a source switch to a destination switch, (2) determining, for each of the plurality of paths, a limiting bandwidth of the path based at least in part on the lowest link bandwidth of one or more data links in the path, and (3) balancing network traffic that is transmitted from the source switch to the destination switch across the plurality of paths based at least in part on the limiting bandwidth of each of the plurality of paths.
