摘要： Examples disclosed herein relate to reducing flooding of route updates of a dynamic routing protocol. In an example, number of route updates received by a router from each neighbor router may be determined, wherein the router may be present in a network using a dynamic routing protocol. Each neighbor router may be classified into one of a plurality of groups of neighbor routers in such a manner that number of route updates originating from each group of neighbor routers is approximately same. A first route update interval may be determined for each group of neighbor routers for sending a respective first set of future route updates therefrom to the router. The respective first route update interval for sending the respective first set of future route updates may be notified to the respective member routers of each group of neighbor routers.
摘要翻译：本文公开的示例涉及减少动态路由协议的路由更新的泛洪。在一个示例中，可以确定路由器从每个相邻路由器接收的路由更新的数量，其中路由器可以使用动态路由协议存在于网络中。每个邻居路由器可以被分类为多个相邻路由器组中的一个，使得源自每组邻居路由器的路由更新数量大致相同。可以为每组邻居路由器确定第一路由更新间隔，以将相应的第一组未来路由更新从其发送到路由器。用于发送各自的第一组未来路由更新的各自的第一路由更新间隔可以被通知给每组邻居路由器的各个成员路由器。

摘要： In some examples, a method is performed through a network device. The method may include determining that a device routing table is in an unconverged state, starting a preempt timer that expires after a preempt duration, delaying a route update communication through a selected communication interface in the network device for converging the device routing table until after the preempt timer expires.

摘要： In some examples, a maximum transmission unit (MTU) is installed by a Software-Defined Network (SDN) controller on a controlled network node for traffic along a datapath in an SDN. The installed MTU can, for example, be selected from MTU sizes in an MTU database for nodes along the datapath. For example, the installed MTU can be selected as the largest allowable MTU size based on the nodes of the datapath.

摘要： Examples disclosed herein relate to restoring a flow path in response to a link failure in a software defined network (SDN). In an example, a backup flow path for a flow may be configured in a network device, on a primary flow path of the flow. In response to determination of a link failure in the primary flow path, the network device configured with the backup flow path may be identified. In an example, the network device may be identified by sending, from a detecting network device that detects the link failure on the primary flow path, a message packet successively to each network device preceding the detecting network device on the primary flow path until the network device configured with the backup flow path is identified. The backup flow path may be used to route packets of the flow.
