On adopting Content-Based Routing in service-oriented architectures

Two requirements of SOAs are the need for a global discovery agency, which assists requesters in finding their required services, and the need for new interaction paradigms, which overcome the limitations of the usual request/reply style. Content-Based Routing (CBR) holds the promise of addressing both these aspects with a single technology and a single routing infrastructure. To provide arguments for our hypothesis, we review the on going efforts for service retrieval and asynchronous communication in SOAs, identify their limitations and the advantages, and discuss how incorporating CBR into SOAs allows to solve most limitations, but also poses some interesting challenges.
