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 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： 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.
摘要翻译： 分组被封装并从服务节点发送到一个或多个应用节点，以将一个或多个第4层到第7层服务应用于分组。 在分组之前，服务节点基于来自外部网络协议（例如但不限于边界网关协议（BGP））的路由数据结构中的分组的目的地地址来执行查找操作。 该查找操作导致从服务节点发送分组的下一跳分组交换设备的标识。 服务节点包括发送到应用节点的请求分组中的下一跳地址的标识。 应用程序节点将该服务应用于数据包后，将将应用服务的数据包发送到下一跳地址。 以这种方式，应用节点不需要运行外部网络协议。 虽然，它们通常将运行内部网关协议，用于识别如何将数据包转发到下一跳地址。

摘要： An apparatus and 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.
