摘要： Systems and methods are disclosed for effectuating control-plane changes at increased speeds to protect a network in which switching operations are performed. Operations to effectuate control-plane changes in the network can be divided between software and more-rapid, dedicated hardware within a line card. Examples of operations reserved to hardware implementation can include blocking and unblocking of ports, flushing of learned entries from switch tables, and coordination of control-plane changes through the generation of messages sent between nodes, and also between line cards of a node. Determinations about the need for hardware-driven, control-plane changes may be made based on events occurring in the network in accordance with any of a number of different network protection protocols. The protocol may be implemented in a state machine and the software may determine the state of the hardware through a master/slave relationship.

摘要翻译： 公开了用于以增加的速度实现控制平面改变的系统和方法，以保护执行切换操作的网络。 实现网络中控制平面变化的操作可以在线卡内的软件和更快速，专用的硬件之间进行划分。 保留给硬件实现的操作的示例可以包括阻塞和解除端口的阻塞，从交换机表中刷新学习的条目，以及通过生成在节点之间发送的消息以及节点的线卡之间的协调控制平面改变。 可以基于根据多个不同网络保护协议中的任何一个在网络中发生的事件来进行关于硬件驱动的控制平面改变的需要的确定。 该协议可以在状态机中实现，并且软件可以通过主/从关系来确定硬件的状态。
