A differentiated routing system includes an electronic service in communication with an ingress gateway that receives a communication service, such as a call from a terminal, over a trunk. The service receives a request from the ingress gateway for establishing a communication service for the calling party terminal. The service obtains information associated with the calling party terminal, which may be based on the trunk and its relationship to a customer, in which the information is to be used for applying at least one of a routing decision and policy decision to the communication service, and appends a tag to the request based on the information. The service may then transmit the request appended with the information to a routing device, which may then use the information when providing the service.

User-based differentiated routing system and method

A differentiated routing system is provided for routing a communication service according to an access point of a subscriber terminal to a first network domain. The system includes a computing system executing a core routing engine (CRE) that receives a request for a communication service from the subscriber terminal. When the communication service is to be routed to a second network domain, the CRE identifies an access point at which the subscriber terminal accesses the first network domain, includes a tag in the request according to the identified access point. The tag includes information to be used by the second network domain for routing the communication service. The CRE then transmits the request to the second network domain.

Differentiated routing system and method

An embodiment of a method for use in performing interoperability testing between two network architectures includes forming multiple transaction signatures that each characterizes a communication transaction conducted over the two networks and analyzing each of the transaction signatures to determine if the transaction signature matches a previously classified pattern. The method may further include generating a report identifying each of the communication transactions and indicating that each of the communication transactions is classified with a classification associated with a previously classified pattern or are of unknown classification. Another method includes receiving a transaction signature composed of multiple transaction elements, and determining whether the received transaction signature corresponds to a previously identified transaction signature pattern. If the transaction signature does not correspond to a previously identified transaction signature pattern, a new transaction signature pattern is created, and classified as one of a plurality of classifications indicative of completion or failure of the communication transaction.
