VXLAN based multicasting systems having improved load distribution

摘要

A virtual extensible local area network (“VXLAN”) system includes servers having VXLAN tunnel end points (“VTEP”) and virtual machines (“VMs”), multiple routers to transmit network data using bidirectional groups (“BIDIRs”) and rendezvous points (“RPs”), and an associated management and provisioning entity (“MPE”) adapted to arrange BIDIRs dynamically based upon network traffic such that traffic is more evenly distributed across the VXLAN. Some of the routers can be preconfigured as potential RPs, and the MPE can activate and deactivate these routers to and from RP status as needed. The MPE creates and rearranges BIDIRs based upon volume thresholds of traffic being reached in BIDIRs, such as by splitting overloaded BIDIRs. Network traffic can be monitored by VTEPs and RPs.

主权项

1. A computing system comprising:
a processor adapted to manage a plurality of routers, the plurality of routers being coupled to a plurality of servers, wherein each of said routers is adapted to facilitate network data communication among the plurality of servers according to multicast trees; and one or more modules adapted to be executed with respect to said processor, said one or more modules being configured to:
dynamically select one or more active rendezvous points (“RPs”) for the multicast trees from among the routers that are potential RPs for the multicast trees so as to balance loads associated with the network data communication; andreceive information on traffic passing through the one or more active RPs.
