Abstract

According to analysis on recent changes in network users’ values and their usage patterns, simple web information and one-way data transfer have declined. Instead, there have been rise in the use of multimedia, rising demand for security and personalization and increase in needs for liberal mobility. It is forecasted that thanks to these changes, current individual services would be gradually integrated in a converged form, and individual networks would evolve into an integrated intelligent network which meets users’ diverse needs. As the Optical Transport Networks become more important, and network traffic is concentrated in the communication network components, it’s been urgent to secure the survivability of the OTN. Therefore, it is critical to provide connectivity that end users want to the network service provider through optimal path allocation between the networks. As federation among international research networks becomes important, and there have been attempts to share a great volume of network resources in optimum conditions these days, it’s been essential to select optimal path and share resources through information sharing among multi-domains. Considering these diversities, therefore, this study has tried to examine architecture and protocol to select optimal path among multi-domains.
