摘要： Packets are encapsulated and sent from a service node to one or more application nodes for applying one or more Layer-4 to Layer-7 services to the packets. Before which for a packet, the service node performs a lookup operation based on a destination address of the packet in a routing data structure derived from a exterior network protocol, such as, but not limited to Border Gateway Protocol (BGP). This lookup operation results in the identification of a next hop packet switching device to which the packet would be sent from the service node. The service node includes this identification of the next hop address in the request packet sent to the application node(s). After the service(s) are applied to the packet, an application node will send the services-applied packet to this next hop address. In this manner, application nodes do not need to run an exterior network protocol. Although, they typically will run an Interior Gateway Protocol for identifying how to forward packets to the next hop address.

摘要： In a data communication internetwork including a source station, an end station, and a default router for the source station, a default communication path including the default router is defined between the source station and the destination station. During operation of the data communication internetwork, a shortcut data communication path by passing the default router is established between the source station and the destination station, such that data packets transmitted by the source station are not received by the default router. After the shortcut communication path has been established, a control frame containing source-route information regarding the source station is transmitted to the router, and the source-route information is stored at the router. In this manner, the default router can efficiently direct data packets to the source station and facilitate the establishment of shortcut communication paths terminating at the source station even though the default router is bypassed by a shortcut communication path.

摘要： A method is implemented to enable networks employing source-route bridging to participate in route switched, Asynchronous Transfer Mode (ATM), networks. Such source-routed networks, for example, Token-Ring LANs, incorporate an end-to-end route description in the data packets transmitted by the source station. The end-to-end route description is contained in a Route Information Field (RIF). The method implemented herein associates an RIF with the ATM address corresponding to a destination station. This permits the source-route bridged network to exploit the efficiencies of layer-2 connections and the high-speed switching characteristics of the ATM network.

摘要： An ATM communications network with several ELANs allows steady-state data to be passed between ATM attached devices which bypasses intermediate LECs and bridges. Connected to the ATM communications network is a bridge unit which includes a bridge and associated LECs. Also, an origination ATM attached device and a destination ATM attached device are attached to the ATM communications network via a first by a first ELAN and a second ELAN, respectively. The origination ATM attached device sends a request for an ATM address associated with the destination ATM attached device to the bridge, via the first ELAN. After some processing, the bridge returns the ATM address associated with the destination ATM attached device to the origination ATM attached device. This allows the origination ATM attached device to establish a shortcut VCC with the destination ATM attached device using the ATM address associated with the destination ATM attached device, thereby bypassing intermediate bridges and LECs.

摘要： An application node advertises service(s), using a label distribution protocol, that it offers to other network nodes and a corresponding label to use to identify these services(s). For example, a Targeted Label Distribution Protocol (tLDP) session may be established between a packet switching device and the application node providing these services to communicate the advertisement. Packets are encapsulated and sent from a service node (e.g., packet switching device) with the corresponding label to have one or more advertised services applied to the packet by an application node (e.g., a packet switching device and/or computing platform such as a Cisco ASR 1000).

摘要： An application node advertises service(s), using a routing protocol, that it offers to other network nodes. For example, the routing protocol used to advertise service(s) in a Service Provider Network is typically an link-state, Interior Gateway Protocol (IGP), such as, but not limited to, Intermediate System to Intermediate System (IS-IS) or Open Shortest Path First (OSPF). Packets are encapsulated and sent from a service node (e.g., packet switching device) using one or more advertised services applied to a packet by an application node (e.g., a packet switching device and/or computing platform such as a Cisco ASR 1000).
