Service classification of web traffic

摘要

A method for communication includes recording, at a gateway to a network, a generic definition of a service provided to clients of the gateway. The generic definition specifies a first Uniform Resource Identifier (URI) on the network that is associated with the service. At least a first communication between a client and the network is processed at the gateway in order to identify at least a second URI that is referenced from the first URI in a context of the service. Responsively to at least the first communication, an extended definition of the service for the client is automatically created by adding at least the second URI to the generic definition. Use of the service is monitored by applying the extended definition to second communications conveyed by the gateway between the client and the network.

1. A method for monitoring communication services, comprising:
at a gateway to a network, managing a set of service definitions corresponding to respective services, each service definition specifying a base Uniform Resource Identifier (URI) on the network that is associated with the corresponding service of the service definition; processing at the gateway communications between a client and the network in order to identify communications with URIs specified in one of the managed service definitions; extracting, from communications with URIs specified in respective service definitions, URIs referenced by the communications, and adding the extracted referenced URIs to the corresponding service definitions; monitoring use of the services by determining for the communications between the client and the network, respective services to which the communications relate, by comparing the URIs of the communications to URIs in the service definitions; and billing the client for content provided to the client in the communications responsive to respective rates associated with the services to which the communications relate, by an operator of the gateway, wherein monitoring the use of the services comprises filtering the identified content determined to relate to a specific service so as to identify whether a data pattern of the content matches a pattern of the service and excluding non-matching content from the context of the service.
