    • State information is synchronized between a plurality of routing engines in a multi-chassis router according to a synchronization gradient. An example multi-chassis router is described that includes a primary routing engine and a standby routing engine in each chassis. According to the synchronization gradient, the primary routing engine of a control node updates state information on the standby routing engine of the control node prior to updating the primary routing engines of the other chassis. The primary routing engines of the other chassis update state information in respective standby routing engines prior to updating state information in consumers. If a primary routing engine fails, the corresponding standby routing engine assumes control of the primary routing engine's duties. Upon assuming control, a standby routing engine resumes updating state information without having to resend state information or interrupt packet forwarding.

    • A device comprises a programmable communication interface and a processor. The programmable communication interface communicates data via a set of signals. The processor configures the programmable communication interface to communicate the data in accordance with a programmed override state for at least one of the signals and actual states for the remaining signals. The programmable communication interface may be configured, for example, to programmably treat an overridden signal as asserted or de-asserted regardless of actual voltages present on one or more electrical connectors associated with the overridden signal. As a result, incorrectly wired electrical connectors of the programmable communication interface may be programmably overridden. Consequently, a technician need not manually rewire the programmable communication interface.
    • 一种设备包括可编程通信接口和处理器。 可编程通信接口通过一组信号传送数据。 处理器配置可编程通信接口以根据针对剩余信号的信号和实际状态中的至少一个的编程覆盖状态来传送数据。 例如,可编程通信接口可以被配置为可以可编程地将覆盖的信号视为被断言或解除断言,而不管存在于与重写信号相关联的一个或多个电连接器上的实际电压。 结果,可编程通信接口的不正确连接的电连接器可以被可编程地覆盖。 因此,技术人员不需要手动重新连接可编程通信接口。

    • A multi-chassis network device sends state information to internal consumers within the multi-chassis device via a hierarchical distribution. As one example, a primary master routing engine within a control node of a multi-chassis router forwards state information to local routing engines within other chassis, which in turn distribute the state information to consumers on each chassis. Each local routing engine defers sending acknowledgement to the master routing engine until acknowledgements have been received from all consumers serviced by the local routing engine. Embodiments of the invention may reduce control plane data traffic and convergence times associated with distribution of state updates in the multi-chassis network device.
    • 多机箱网络设备通过分层分发向多机箱设备内的内部消费者发送状态信息。 作为一个示例,多机架路由器的控制节点内的主要主路由引擎将状态信息转发到其他机箱内的本地路由引擎,而另一个机箱又将状态信息分配给每个机箱上的消费者。 每个本地路由引擎将发送确认发送到主路由引擎,直到从本地路由引擎所服务的所有消费者接收到确认。 本发明的实施例可以减少与多机箱网络设备中的状态更新的分配相关联的控制平面数据流量和收敛时间。
