摘要： Packets are encapsulated and sent from a service node to an application node for applying one or more Layer-4 to Layer-7 services to the packets, with service-applied packets being returned to the service node. An identification of a virtual private network (VPN) may be carried within a request packet, encapsulating a particular packet, sent by a service node to an application node for applying a service to the particular packet; with the corresponding response packet sent to the service node including an identification of the VPN for use by the service node in forwarding the services-applied packet. Additionally, parameters may be included in a request packet to identify a particular service of a general service to be applied to a particular packet encapsulated in the request packet.

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).

摘要： Packets are encapsulated and sent from a service node (e.g., packet switching device) using one or more 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) to generate a result, which is used by the service node to process packets of a flow of packets to which the packet belonged. An example of a service applied to a packet is a classification service, such as, but not limited to, using deep packet inspection on the packet to identify a classification result. The service node can, for example, use this classification result to process other packets in a same packet flow, such that all packets of a flow do not need to be, nor typically are, sent to an application node for processing.

摘要： An interface method to provide a portable networking interface for distributed switching systems. Two Application Program Interfaces (APIs) are defined for communication to a Forwarding Database Distribution Library (FDDL). The FDDL sits between network client applications and the switch device driver in order to provide a uniform interface to the switch device driver. Towers may be added to the FDDL to provide additional functionality specific to certain client applications.

摘要： To insure connection resiliency two LECs are defined in normal practice in which a lengthy and extensive recovery procedure is enforced in case of an ATM interface failure. In the present invention only one LEC is configured. This LEC is configured to be If the active ATM interface fails, the bridge is not notified of the failure as would normally happen. The LEC associates itself with the alternate ATM and rejoins the ELAN via the alternate ATM interface. The ELAN Join Procedure is one of the LAN Emulation protocols. After the ELAN has rejoined, the LEC automatically re-establishes the previously existing Data Direct VCCs (bi-directional point to point LAN Emulation connection established from one LEC to another) using its LE_ARP (LAN Emulation Address Resolution Protocol) cache entries.
