摘要： Methods for configuring networks and systems including nodes and switches. In one aspect, a method includes selecting a (v, b, r, k, λ) balanced incomplete block design (BIBD), wherein the BIBD includes v elements and b blocks of k elements, each element of the v elements is in r blocks of the b blocks, and each distinct pair of elements of the v elements is in λ blocks of the b blocks. Nodes are connected to switches. Each node is assigned to a different element of the BIBD. Each switch is assigned to a different block of the BIBD. For each switch, the switch is connected to the nodes assigned to the elements included in the block assigned to the switch.

摘要： Efficient and highly-scalable network solutions are provided that each utilize deployment units based on Clos networks, but in an environment such as a data center of Internet Protocol-based network. Each of the deployment units can include multiple stages of devices, where connections between devices are only made between stages and the deployment units are highly connected. In some embodiments, the level of connectivity between two stages can be reduced, providing available connections to add edge switches and additional host connections while keeping the same number of between-tier connections. In some embodiments, where deployment units (or other network groups) can be used at different levels to connect other deployment units, the edges of the deployment units can be fused to reduce the number of devices per host connection.

摘要： A method is provided for a router to implement non-stop routing of a routing protocol. The router has primary and backup routing engines or a single routing engine. When the primary routing engine or the only routing engine is operating normally, neighbor state information is backed up to the backup routing engine or a nonvolatile memory in the router. After the backup routing engine takes over for the primary routing engine or the single routing engine reboots, the backup routing engine or the single routing engine maintains neighbor relationships based on the neighbor state information, obtains routing information based on the saved neighbor state information. The backup routing engine or the single routing engine then generates local routes based on the routing information, determines best routes based on the local routes, sends the best routes to the neighboring routers, and saves the best routes to local hardware.

摘要： A network element is configured for synchronizing dynamic OSPF data between an active OSPF instance and a backup OSPF instance. Upon an OSPF data synchronization event, the active OSPF instance synchronizes dynamic OSPF data with the backup OSPF instance. Upon receiving the dynamic OSPF data, the backup OSPF instance determines whether the requisite data structures exist. If the data structures do not exist, the backup OSPF instance returns a NACK to the active OSPF instance and clears its dynamic OSPF data. Responsive to receiving the NACK, the active OSPF instance resynchronizes its dynamic OSPF data with the backup OSPF instance.

摘要： A network switch including a plurality of stack units sequentially linked to each other. Each stack unit includes a port, a forwarding engine, a first interface, and a second interface. The second interface of each stack unit is linked to the first interface of a subsequent stack unit. The second interface of a last stack unit is linked to the first interface of a first stack unit. In response to a packet traveling in a first direction from the first stack unit to the last stack unit and a link between a second stack unit and a third stack unit being inoperative, the forwarding engine of the second stack unit returns the packet in a second direction to a preceding stack unit. The packet travels in the second direction from the preceding stack unit to the first stack unit, to the last stack unit, and to the third stack unit.

摘要： An OpenFlow network includes multiple controllers. Each controller includes a load control table and a load control unit. The load control table controls at least one of the number of messages which each of switches in the OpenFlow network has transmitted to a controller controlling the switch over a predetermined time and the number of packets that the switch has received over a predetermined time. When a predetermined event occurs, the load control unit detects a controller having a processing load higher than or equal to a first threshold on the basis of the load control table and places at least one of the switches controlled by the detected controller under the control of another controller.

摘要： Generally, this disclosure describes a scalable cluster router that includes a plurality of server-class computers interconnected together to form a router. Each server may be configured to independently schedule switching of packets to reduce the switch speed requirements on a per server basis. Each server may include a scheduler that independently load balances packet flows across servers of the cluster. Router capacity may be incrementally scaled by adding more servers, and router capacity may be increased by load balancing techniques within individual servers.
