    Abstract: The techniques disclosed herein enable systems to perform ordered reconvergence operations following a change to a topology of a communications network. To perform ordered reconvergence, a system detects a change to network topology such as a link failure or node addition. In response, the system determines a global delay based on a maximum distance between two nodes within the network, a local delay for each node within the network, and an ordered delay for each node based on the global delay and the local delay. Upon detecting that the ordered delay for a node has elapsed, the system can then update a routing table for the node. After updating routing tables for every node, the system can route data in the changed network topology using the updated routing tables.

    Abstract: Examples disclosed herein relate to a method comprising receiving a control packet originating from a originating network device. The control packet may have a control MAC address identifying the originating network device and the control packet is used for determining a traffic loop in a network including the first network device and the originating network device. The method may include determining, by the first network device, whether the control MAC address of the control packet matches a MAC address of the first network device. Wit is determined that the control MAC address of the control packet matches a MAC address of the first network device, the method may include determining that the match is indicative of the loop and blocking a port of the first network device that the control packet arrived on without blocking any other ports on the first network device. When it is determined that the control MAC address of the control packet does not match the MAC address of the first network device, the method may include transmitting the control packet to a second network device on the network without blocking any port on the first network device that received the control packet.

    Abstract: This application provides a VXLAN packet processing method, a device, and a system. After determining that a data packet sent by a CE device is a BUM packet, a PE device encapsulates the BUM packet to generate a VXLAN packet including an ESI label and a VXLAN packet including a BUM traffic label. The VXLAN packet including the ESI label is sent to an active-active gateway, so that the gateway can block forwarding of traffic to the CE device by using an interface configured with an ESI, to avoid a loop between the PE device and the CE device. The VXLAN packet including the BUM traffic label is sent to a remote PE, to block forwarding of the VXLAN packet to the CE device by using a secondary DF interface, thereby avoiding a multi-packet problem.

    Abstract: Systems and methods for using InfiniBand routing algorithms for Ethernet fabrics in a high performance computing environment. The method can provide, at a computer comprising one or more microprocessors, a plurality of switches, a plurality of hosts, a topology provider (TP) module, a routing engine (RE) module, and a switch initializer (SI) module. The method can perform a discovery sweep, by the TP, of the plurality of hosts and the plurality of switches and assigns an address to each of the plurality of hosts and the plurality of switches. The method can calculate, by the routing engine, a routing map, based upon a routing scheme, for the plurality of hosts and the plurality of switches, the routing map comprising a plurality of forwarding tables. The method can configure, each of the plurality of switches with a forwarding table of the plurality of forwarding tables calculated by the routing engine.

    Abstract: A data packet transmission method and a border routing bridge device, where the method includes receiving, by a first border routing bridge device of a first area, a first data packet sent by a border routing bridge device of a second area to the first area, determining, a device identifier group of the second area according to the first data packet, determining, from the device identifier group of the second area, according to the first data packet, a device identifier of a border routing bridge device used to forward a return data packet sent by the target device to the source device, and sending, by the first border routing bridge device, a second data packet carrying the determined device identifier to the target device, where the determined device identifier is used as a source routing bridge device identifier of the second data packet.

    Abstract: A Protocol Independent Multicast (PIM) designated networking device election system includes a first networking device and a second networking device that are coupled to the first edge device. The second networking device receives a first PIM message from the first networking device and determines that the first PIM message indicates that the first networking device supports designated networking device election based on an interface performance property. The second networking device then determines whether a first interface performance property indication indicates that a first interface performance property of the first networking device or a second interface performance property of the second networking device satisfy an interface performance property condition. In response to determining that the second interface performance property satisfies the interface performance property condition, the second networking device forwards first data traffic received at the second networking device toward the first edge device.
