摘要： A system for identifying a subscriber includes an access server coupled to a number of subscribers using a first communication network and further coupled to a second communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the first communication network. The memory stores path information that identifies a virtual circuit assigned to the particular subscriber. The processor identifies the particular subscriber for connection to the second communication network based upon the path information and the particular virtual circuit used to receive the communication from the particular subscriber.

摘要： A system for determining subscriber information includes an access server coupled to a number of subscribers using a communication network, a memory coupled to the access server, and a processor coupled to the memory. The access server receives a communication from a particular subscriber using a particular one of a number of virtual circuits associated with the communication network. The memory stores subscriber information for the subscribers, wherein the subscriber information is indexed by path information that identifies a virtual circuit assigned to the particular subscriber. The processor determines subscriber information for communication to the particular subscriber based upon the path information and the particular virtual circuit used to receive communication from the particular subscriber.

摘要： A system and method classifies packets with a programmably fixed network processor program and dynamically updated data structures. The network processor program selects predetermined packet field values of the packets transmitted across the network and classifies the packets by matching one or more packet field values with a data structure. New packet classifications are dynamically created by updating the data structure to associate one or more predetermined packet field values with the new packet classification. For instance, a parse tree program extracts packet header information and matches the packet header information to the data structure. A pattern tree data structure provides longest prefix matches and an ordered tree data structure provides combination matches so that classification of arbitrary Boolean combinations of extracted header fields can be formed.

摘要翻译： 系统和方法使用可编程固定的网络处理器程序和动态更新的数据结构对数据包进行分类。 网络处理器程序选择通过网络发送的分组的预定分组字段值，并通过将一个或多个分组字段值与数据结构相匹配来对分组进行分类。 通过更新数据结构来动态创建新的分组分类，以将一个或多个预定分组字段值与新的分组分类相关联。 例如，解析树程序提取分组报头信息，并将分组报头信息与数据结构相匹配。 模式树数据结构提供最长的前缀匹配，并且有序树数据结构提供组合匹配，使得可以形成提取的报头字段的任意布尔组合的分类。

摘要： A network node includes a classify engine interfaced with the Internet. The classify engine accepts packets from the Internet and determines classification information for each packet. A process engine is interfaced with the classify engine, and has ports, each port being associated with a function. A controller is interfaced with the classify engine and the process engine. The controller programs the classify engine with a dataflow program to route each packet to a predetermined port of the process engine based on the classification information of the packet.
