Optical Network Control Using Web Services Mechanism

With the rapid growing of internet services in the recent decades, the requirements in high speed and huge volume of data transfer such as IPTV, video meeting, became the newly increasing points of internet business. However, these new requirements give out a serial of problems in effectively managing the network. In older to solve these problems, the ASON (Auto-Switch Optical Network), which has advantage in assigning bandwidth and effectively managing optical network, is wildly used and considered as the core of next generation network.Nevertheless, with the development of ASON and the enlarged scale of optical network, the distribute and localized characters of optical network make the existed simple network model be no longer suitable for the real distribute management and for there is no standards about the inter-domain network communication, the problem of inter-domain communication becomes more complex. In order to solve these problems, we creatively use Web Services model of computer network in optical network and carry out a solution basis on Web Services mechanism. This solution adds a new upper layer to solve the lower layer communication problem, and design a center controller to solve the multi-domain resource management problem. Also, we use grid model and software to demonstrate the solution. The main contents of this thesis is arranged as follows:Firstly, we discuss the architecture and related technologies of ASON, and point out the necessary of domain division in optical network. Then we discuss the current research work on inter-domain communication and optical resource management, and conclude that they are focus on single domain multicasting or multi-domain unicasting but no solution on inter-domain multicasting.Then, we introduce the Web Services model and mechanism on computer network. This part concentrates on the relationship between Web Services and SOA, and indicates that the Web Services model is developed from SOA but is descried and defined more strictly than SOA.Next, we demonstrate the way to apply Web Services model in optical network. And we discussed the mechanism using UNI (User Network Interface) to control the primary layer of optical network. Also, we discuss the details of BUNIA component, which helps us use Web Services model in optical network.And then we discuss the method of using Web Services in inter-domain multicasting. We extend the existing domain model, add new items and give a short analyze about the current research work on multi-domain management, basis on which we carry out our own inter-domain multicast model.
