With ASON network scale enlarging, many ASON networks often meet trouble for fastly setuping a service and restoration even in current ring network. It would be more serious trouble in mesh network. Firstly, the two part main time factor is proposed. Then the current methods are introduced to accelerate the speed for setuping a service. The first method is to keep network topology in every node by...
In this paper, we introduce the application of topology aggregation in PCE-based WSON network. A wavelength capability matrix was proposed for dealing with the compression of the information about wavelength convertibility. In large scale hierarchical networks, network state information can be effectively compressed by applying topology aggregation and the overhead of communication between PCEs would...
Recent advances in multimedia technologies have led various enhanced multimedia services such as high-quality content-sharing. In particular, in order to deliver and distribute high-quality content effectively, a fiber channel arbitration loop- (FC-AL) based network architecture has been presented, combined with a consumer device, such as a personal video recorder (PVR). Moreover, in order to overcome...
This paper presents a new architecture for optical burst switched networks where the control plane of the network functions in a cooperative manner. Each node interprets the data conveyed by the control packet and forwards it to the next nodes, making the control plane of the network distribute the relevant information to all the nodes in the network. A cooperation transmission tree is used, thus...
Ring architectures have been widely used by telecommunications carriers for the deployment of networks based on synchronous optical network (SONET) and wavelength division multiplexing (WDM). These architectures have several attractive properties that make them desirable for a large number of applications. Even though arbitrary mesh network architectures provide additional degrees of freedom and are...
The feasibility of the residential area network architecture has been proposed, combined with personal video recorders (PVRs) and the fiber channel-arbitration loop (FC-AL) connection. However, the single-loop FC-AL-based architecture has the limitation on scalability. That is, the architecture only can allow 127 devices, thereby it cannot support the densely-populated apartments or buildings with...
