Systems and methods for dynamically adaptive multi-way message conversion

摘要

Multilateral, dynamic and coordinated message conversion between different messages composed using different protocols, e.g., Session Initiation Protocol (SIP) and Simple Object Access Protocol (SOAP) are described. For each message pattern or set of messages between coordinated peers, a conversion session is established. Incoming messages are correlated to their respective conversion sessions so that a common set of conversion rules can be used to convert messages within a particular session.

1. A system for converting an incoming message of a first message type into an outgoing message of a second message type comprising:
a repository for containing a plurality of Protocol Conversion and Coordination Language (PCCL) specifications comprising:
a specification of peers;a set of session correlation rules;a set of matching rules; andan action specification; a PCCL application compiled from a PCCL specification selected from the plurality of PCCL specifications; a message receiver processor, which uses the set of specification of peers in a first domain, to identify one or more peers communicating via an incoming message of a first type; a session correlator, which applies the set of session correlation rules to the identified peers and information extracted from content of the incoming message to map the incoming message to a PCCL session among a plurality of PCCL sessions if an appropriate PCCL session is already active or to a newly created PCCL session if an appropriate PCCL session does not exist; a condition matcher, which uses the set of matching rules and session data of the PCCL session to which the incoming message is mapped, to determine a set of actions to be performed to convert the incoming message into an outgoing message of a second type; an action executor which uses the action specification to execute the set of actions; and a message sender processor which sends said outgoing message to one or more peers in a second domain.
