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.

摘要： A switch IHS stacking system includes a plurality of switch IHSs. A least one first switch IHS includes a first processing system and at least one second switch IHS includes a second processing system that is different from the first processing system. A stacking engine is located on each of the plurality of switch IHSs. Following the coupling of the plurality of switch IHSs into a stack and in response to the startup of the plurality of switch IHSs, the each of the stacking engines may exchange capability information with each of the plurality of switch IHSs and determine a control plane processing system affinity and a data plane processing system affinity for each of the plurality of switch IHSs. The stacking engines may then determine a master switch IHS for the stack that has the highest control plane processing system affinity and data plane processing system affinity.

摘要： Embodiments of the present disclosure comprise considering the performance of an application under different candidate physical network topology configurations for a set of virtual machines (VMs) for an application. Given different physical network topologies corresponding to the logical topology for the application, each physical network topology may be analyzed to quantify the performance of the application based upon one or more metrics. In one or more embodiments, the metrics may include throughput, latency, and network resource usage, and these metrics may be formed into a performance set. The set of values provide a means by which the different physical network topology deployments may be compared. Based upon the comparison, a deployment of the VMs on the physical network topology may be selected and implemented; or alternatively, when input expected application performance parameters are satisfied by the metrics, the corresponding physical topology may be chosen.

摘要： An inter-datacenter multicast system includes a first datacenter connected to a second datacenter. A first multicast router device is located in the first datacenter and includes at least one first multicast router interface that provides a link to the second datacenter, and a second multicast router device is located in the second datacenter and includes at least one second multicast router interface that provides a link to the first datacenter. The first multicast router device and the second multicast router device sync multicast routes with each other to enable each to act as respective designated routers, and also each remove multicast router interfaces that provides links to the other datacenter from outgoing interface Virtual Local Area Networks (VLANs) that are part of a multicast route, which prevents traffic tromboning and reduces multicast data communications between the first datacenter and the second datacenter.
