Grid-Based Service Creation for Next-Generation Networks

Compared with traditional telecommunication networks, service creation in next-generation networks (NGN) gives rise to new opportunities and challenges. In this paper, we propose a NGN service creation model SECOM and its two criteria, that is, OPEN and INTEGRATION of network capabilities. OPEN enables a uniform access to heterogeneous network capabilities, while INTEGRATION enables loose-coupled distributed open services to be converged. We implement a prototype ParlayGS based on Parlay and open grid services architecture (OGSA), which implement OPEN and INTEGRATION criteria all in one. Simulations were made to illustrate and verify the open and integration aspects of ParlayGS on creating services. Our efforts show that SECOM and its prototype ParlayGS are valid and effective, which not only supports new complex services spanning heterogeneous networks, but also enables flexible and rapid ways for service interconnection with lower protocol conversion complexity.
