摘要： Methods of load-balancing in a network are provided herein. One such method includes steps of receiving network traffic at a network device, the network traffic having a destination address and of performing a look-up in a multipath group table using the destination address. The multipath group table includes entries for recursive next-hops, each recursive next hop being associated with a connected next hop in the multipath group table. The method also include a step of hashing the network traffic according to a number of recursive next-hops associated with the destination address in the multipath group table. Additional methods and information handling system are also provided.

摘要： An information handling system is provided. The information handling system includes a customer edge device coupled to a provider edge device. The customer edge device provides a default virtual routing and forwarding (VRF) instance that receives a multicast stream from the provider edge device. The information handling system also includes a plurality of host devices and a plurality of virtual local area networks (VLANs). Each of the VLANs includes at least one of the host devices and is assigned to a subscribing VRF instance, with each of the subscribing VRF instances subscribing to the default VRF instance in order to receive a copy of the multicast stream from the provider edge device. The single copy of the multicast stream is transmitted over the PE-CE link regardless of the number of subscribing VRFs.

摘要： An information handling system is provided. The information handling system includes an ingress network device receiving a multicast stream from a coupled source device and a first and a second egress network device. The first and second egress network devices each receive the multicast stream for coupled destination devices. The information handling system also includes a plurality of intermediate network devices by which the ingress network device is coupled to the first and second egress network devices to form a network and further includes a network controller. The network controller has a topology of the network in a memory and forms a multicast tree based on the topology as well as a link load level and a multicast replication capacity associated with links to the first and second egress network devices and to each of the plurality of intermediate network devices.

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.
