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.

Systems and methods for load balancing in a data center

A system for operating information handling systems forming a network including a plurality of switches is provided. The system includes an open flow controller coupled to each of the plurality of switches; a plurality of links, each link configured to transmit data packets between two switches from the plurality of switches; wherein: the open flow controller is configured to determine a traffic flow across each of the plurality of links; and each one of the plurality of switches is configured to re-route a data packet when the traffic flow in a link associated to the switch exceeds a threshold. A computer program product including a non-transitory computer readable medium having computer readable and executable code for instructing a processor in a management unit for a plurality of information handling systems as above is also provided. A network managing device coupled to a service provider having resources is also provided.

System and methods for load placement in data centers

An information handling system is provided. The information handling system includes a network orchestration service running on a computer processor. The network orchestration service provides a Border Gateway Protocol (BGP) listener module and a topology builder module. The BGP listener module is configured to receive information from a plurality of spine devices configured as an autonomous system and the topology builder module is configured to use the information received by the BGP listener module to create a topology of a data center that includes the plurality of spine devices. Additionally, the network orchestration service is in communication with a memory that is used to store information received by the BGP listener module and the topology of the data center. Applications of the information handling system for better operating the data center are also provided.

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.

An information handling system is provided. The information handling system includes a plurality of core devices coupled to each other and to a plurality of distribution devices and a plurality of top-of-rack devices coupled to a plurality of servers and to the distribution devices. The plurality of servers are running hypervisors thereon that each manage a virtual switch and a plurality of virtual machines (VMs). The information handling system further includes a plurality of local network address resolution mediators, with each local network address resolution mediator running on one of the plurality of servers and receiving packets from VMs running thereon, and a global network address resolution mediator running on one of the plurality of core devices. The global network address resolution mediator is in communication with each of the plurality of local network address resolution mediators to collect and distribute packets from the plurality of VMs.

Systems and methods for a data center architecture facilitating layer 2 over layer 3 communication

An information handling system is provided. The information handling system includes a first, a second, a third, and a fourth network device. The first network device is coupled to the second network device and to the third network device, while the fourth network device is also coupled to the second and third network devices. At least the fourth network device has a plurality of interfaces and one or more processors in communication with the interfaces and a memory. At least one of the one or more processors is configured to disassociate a network address of the first network device from a first VRF instance and associate the network address of the first network device with a second VRF instance when a network failure associated with the first VRF instance is detected. Methods for rerouting traffic through the information handling system in response to a network event are also disclosed.

Systems and methods for tunnel-free fast rerouting in internet protocol networks

A virtual extensible local area network ('VXLAN') system includes servers having VXLAN tunnel end points ('VTEP') and virtual machines (&#x201c;VMs&#x201d;), multiple routers to transmit network data using bidirectional groups (&#x201c;BIDIRs&#x201d;) and rendezvous points (&#x201c;RPs&#x201d;), and an associated management and provisioning entity (&#x201c;MPE&#x201d;) 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.

Systems and methods for load-balancing in a data center

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.
