Quality of Service support plays a major role in the Next Generation Internet. QoS routing protocols must cope with service differentiation to enhance this support. This paper proposes a service aware QoS routing protocol, the Multi-Service routing, which is an extension to traditional intra-domain routing protocols. It proposes a new path selection policy that guides higher priority traffic th...

The paper presents energy efficient routing algorithms based on a novel integrated control plane platform. The centralized control plane structure enables the use of flexible heuristic algorithms for route selection in optical networks. Differentiated routing for various traffic types is used in our previous work. The work presented in this paper further optimizes the energy performance in the ...

Multimedia and graphics data including video, audio, and realistic animations, are entertaining, informative, and intuitive. The information is continuously updated, in which the timing of the data is part of their semantics, and must be maintained both within a data stream and between related data streams. Operating system support for the soft real-time needs of multimedia applications is cruc...

In an integrated services network, resources are shared by multiple traffic classes. Service classes that deliver Quality-of-Service (QoS) to applications have priority over others that do not. In such a multi-service network, routing decisions for high priority QoS traffic will affect what resources are available for lower priority traffic: Poor route selection can result in congestion for, or...

Different visual perception characteristic saliencies are the key to constitute the low-complexity video coding framework. A hierarchical video coding scheme based on human visual systems (HVS) is proposed in this paper. The proposed scheme uses a joint video coding framework consisting of visual perception analysis layer (VPAL) and video coding layer (VCL). In VPAL, effective visual perception...

The European Regulator Group (ERG) defines Bitstream Access Service as a wholesale service offered by a broadband network operator with significant market power to an Internet Service Provider, and identifies it as a market subject to regulation. This paper develops a cost model for the Bitstream Access Service under xDSL technology, following the recommendations of the ERG, considering differe...
