摘要： Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with validation of routes advertised by Border Gateway Protocol. One embodiment validates or invalidates a route received in a Border Gateway Protocol (BGP) update message. A route is validated in response to determining that the originating autonomous system specified in the AS_Path attribute for the route in a received BGP update message has authority to advertise the route and/or whether or not multiple autonomous systems identified in the AS_Path attribute of the update message is authorized to advertise the route, possibly in a particular order.

摘要： In one embodiment, a network server layer provides disjoint channels in response to client-layer disjoint path requests. For example, the network layer can be an optical network, and the client layer may be a packet switching layer (e.g., label switching, Internet Protocol). In one embodiment, a server-layer node receives a client-layer disjoint path request to provide a server-layer channel through a server-layer network. The client-layer disjoint path request includes an identifier corresponding to an existing client-layer path that traverses a current channel through the server-layer network that does not include the server-layer node. The server-layer network determines a particular channel through the server-layer network that is disjoint to the current channel based on route information of the current channel, and then signaling is performed within the server-layer network to establish the particular channel.

摘要： In an example embodiment, a method is provided that receives a broadcast of available bandwidth from a first routing device. A congestion of traffic is detected along a downstream path to a second routing device. This second routing device is an immediate downstream neighbor. As such, an alternate path is established to the second routing device by way of the first routing device based on the available bandwidth in the network and a portion of the traffic is transmitted along the alternate path.

摘要： In an embodiment, a method is provided at which it is used in a device. In this method, a logical identifier assigned to the device is identified and additionally, a mesh group identifier identifying a mesh group is identified. The logical identifier and the mesh group identifier are encoded in a routing message, which is used in an inter-domain routing protocol, and this routing message is transmitted to a reflector device in communication with the device. The reflector device is configured to transmit the routing message to a remote device included in the computer network.

摘要： Disclosed are, inter alia, methods, apparatus, computer-readable media, mechanisms, and means for interconnecting forwarding contexts using U-turn ports. A U-turn port typically comprises an egress port and an ingress port such that packets placed in the egress port are automatically forwarded to the ingress port. Other forwarding contexts are able to communicate packets to a next-destination forwarding context by sending these packets to the U-turn port of the next-destination forwarding context.

摘要： Packets destined for the route processor of a packet switching device are rate controlled. Typically, line cards are configured to rate limit packets of offending packet flows destined for the route processor, such, but not limited to in response to a quantity of packets in the route processor. Filtering of packets of offending packet flows at the line cards reduces the work required of the route processor.

摘要： A service is applied in a packet switching device to both directions of a flow of packets through the packet switching device, with the application of this Layer-4 to layer-7 service to one direction requiring state information shared from the application of the service to packets traversing in the other direction. The service (e.g. firewall, network address translation) can be applied by different processing complexes which do not share memory; thus, state information is communicated between the processing complexes. When the service is applied by a single processing complex, packets can be directed explicitly to the single processing complex. The inline application of services in a packet switching system typically eliminates the need to change a packet's path through the packet switching system to that through a dedicated application server, and may eliminate the need for a dedicated services card or blade server.
摘要翻译：在分组交换设备中通过分组交换设备将分组交换设备应用于分组流的两个方向，通过将该第4层到第7层服务应用于需要从服务的应用共享的状态信息到一个方向数据包在另一个方向上移动。服务（例如防火墙，网络地址转换）可以由不共享存储器的不同处理复合体应用; 因此，在处理复合体之间传送状态信息。当服务由单个处理复合体应用时，数据包可以被明确地定向到单个处理复合体。分组交换系统中的业务的在线应用通常消除了通过分组交换系统将数据包的路径改变为通过专用应用服务器的路径的需要，并且可以消除对专用服务卡或刀片服务器的需要。
