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 virtual extensible local area network (“VXLAN”) system, comprising:
a plurality of servers, each having a VXLAN tunnel end point (“VTEP”) and a plurality of virtual machines (“VMs”) thereupon; a plurality of routers coupled to said servers, each being adapted to facilitate the transmittal of network data between the plurality of servers therethrough according to designated bidirectional groups (“BIDIRs”) having designated VMs thereupon, wherein more than one of said plurality of routers are preconfigured as potential rendezvous points (“RPs”) for BIDIRs; and a processor coupled to said plurality of routers, said processor having a management and provisioning entity (“MPE”) located thereupon, wherein said MPE is adapted to arrange BIDIRs dynamically based upon traffic passing through said plurality of routers such that traffic is more evenly distributed across the VXLAN.
