摘要： A system distributes extended traffic accounting information of bandwidth availability on links throughout a network. For example, routers within the network utilize an extended reservation protocol to calculate bandwidth availability information for links. In calculating the bandwidth availability information, the extended reservation protocol accounts for not only the amount of bandwidth reserved on each of links via the resource reservation protocol itself, but also for the bandwidth usage by other traffic on the links, such as Label Distribution Protocol (LDP) traffic or Internet Protocol (IP) traffic. The routers exchange bandwidth availability information using a routing protocol to gain network-wide knowledge of bandwidth availability.

摘要： Constraint information associated with peering links is taken into account when establishing label switched paths (LSPs) to exit points of a network. Devices within the network, such as routers, designate interfaces associated with peering links as “passive interfaces” to indicate that the interfaces should be included for bandwidth accounting purposes and internal path computation. Other devices within the network utilize the constraint information, e.g., bandwidth availability, when computing and establishing LSPs to the exit points of the network to avoid congested peering links.
摘要翻译：当建立标签交换路径（LSP）以退出网络点时，会考虑与对等链路相关联的约束信息。网络中的设备（如路由器）将与对等链路相关联的接口指定为“被动接口”，以指示接口应包含在带宽计费和内部路径计算之中。当网络的出口点计算和建立LSP以避免拥塞的对等链路时，网络内的其他设备利用约束信息，例如带宽可用性。

摘要： A routing protocol, such as the Border Gateway Protocol (BGP), is extended in a manner that allows the protocol to opaquely carry routing attributes associated with an origin of a routing advertisement, e.g., a customer network of associated with a virtual private network (VPN). These attributes are carried within routing communications using a separate attribute set, and are automatically utilized when delivering the routing advertisement to other customer networks associated with the VPN. As a result, the customer networks are isolated from the routing attributes used within an intermediate network coupling the customer networks.
摘要翻译：诸如边界网关协议（BGP）的路由协议以允许协议不透明地携带与路由通告的原点相关联的路由属性的方式进行扩展，例如与虚拟专用网络相关联的客户网络（ VPN）。这些属性在使用单独的属性集合的路由通信中携带，并且在将路由通告递送到与VPN相关联的其他客户网络时被自动利用。因此，客户网络与在耦合客户网络的中间网络中使用的路由属性隔离。

摘要： In general, techniques are described in which a plurality of network switches automatically configure themselves to operate as a single virtual network switch. A virtual switch is a collection of individual switch devices that operate like as single network switch. As described herein, network switches in a network that are capable of participating in a virtual switch may automatically discover one another. The participating network switches may then elect one of the participating switches as a master switch. The master switch may generate forwarding information and store the forwarding information in the participating switches, including the master switch. The forwarding information causes the participating switches to act like a single network switch.

摘要： A device includes a primary control unit and a standby control unit. The standby control unit records routing communications exchanged between the primary control unit and an external routing device in accordance with a routing protocol. A standby routing process executing on the standby control unit processes the recorded routing communications when the primary control unit fails. The standby routing process generates state information for executing the routing protocol on the standby control unit without requiring that routing sessions be reestablished with the external routing device.
摘要翻译：设备包括主控制单元和备用控制单元。备用控制单元根据路由协议记录在主控制单元和外部路由设备之间交换的路由通信。在主控制单元发生故障时，在待机控制单元上执行的备用路由处理处理记录的路由通信。备用路由处理生成用于在备用控制单元上执行路由协议的状态信息，而不需要与外部路由设备重新建立路由会话。
