VXLAN BASED MULTICASTING SYSTEMS HAVING IMPROVED LOAD DISTRIBUTION

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.
