摘要： A network device and a method are provided. The network device may include a plurality of elements and a routing infrastructure. The routing infrastructure may be configured to route network traffic received at the network device, and transfer, among two or more of the elements, packets that include management information related to the routing of the network traffic.
摘要翻译：提供网络设备和方法。网络设备可以包括多个元件和路由基础设施。路由基础设施可以被配置为路由在网络设备处接收的网络流量，并且在两个或更多个元素之间传送包括与网络流量的路由相关的管理信息的分组。

摘要： A network system uses a management routing instance to route management information between elements involved in management of the system. The system registers each element in the management routing instance when the element comes on line. Based on the management routing instance, the system creates management forwarding tables. The system then uses the management forwarding tables to route management information between the elements. Multiple systems, for example systems connected by a network, may exchange management routing instance information to allow elements in different systems to communicate management information with each other.
摘要翻译：网络系统使用管理路由实例在系统管理涉及的元素之间路由管理信息。当元素上线时，系统会注册管理路由实例中的每个元素。基于管理路由实例，系统创建管理转发表。然后，系统使用管理转发表来在元素之间路由管理信息。多个系统（例如由网络连接的系统）可以交换管理路由实例信息，以允许不同系统中的元件彼此通信管理信息。

摘要： This application describes techniques for peer-agnostic socket replication to implement graceful failover. An exemplary method to enable non-stop routing includes receiving a packet with a first routing engine of a network device having the first routing engine and a second routing engine configured as a backup routing engine, replicating, before processing the packet at a transport layer, the packet to form a replicated packet, sending the replicated packet from the first routing engine to the second routing engine, receiving, at the first routing engine, an acknowledgement from the second routing engine acknowledging reception of the replicated packet, after receiving the acknowledgment, processing the packet at the transport layer of the first routing engine to extract application-layer data and assemble a routing message, and storing the application-layer data from the processed packet in a socket associated with a routing process of the first routing engine.
摘要翻译：本应用程序描述了用于实现平等故障切换的无可比拟的套接字复制技术。启用不间断路由的示例性方法包括：在具有第一路由引擎的网络设备的第一路由引擎和配置为备份路由引擎的第二路由引擎之前，在处理传输层处的分组之前复制分组，所述分组形成复制分组，将所述复制分组从所述第一路由引擎发送到所述第二路由引擎，在接收到所述确认之后，在所述第一路由引擎处从所述第二路由引擎接收确认所述复制分组的接收的确认，在第一路由引擎的传输层处理分组以提取应用层数据并组合路由消息，并将来自处理的分组的应用层数据存储在与第一路由引擎的路由进程相关联的套接字中。
