Design and performance evaluation of Wireless Multi-Protocol Label Switching (WMPLS)

Scope and Method of Study: The research presented in this document focuses on the design of a new protocol for high-speed wireless data communications. The primary goal of this new design is to overcome the limitations of its predecessors, while minimizing the needed resources and maximizing throughput and efficiency in its operations. Another important goal of the study is to provide a homogeneous protocol for wired and wireless networks in order to provide complete interoperability for overlay models and other protocols that can be designed on the basis of this work. The performance evaluation part of this document shows the areas in which improvement has been achieved over previous protocol implementations, and it also shows the areas in which further research is needed in order to improve the performance at least to the levels set by previous protocols.Findings and Conclusions: This study shows that a native wireless design and implementation of the Multi-Protocol Label Switching (MPLS) protocol provides improvements in the field of wireless data communications, providing a homogeneous platform for voice and data communication networks. The research is open for further improvements and modifications for services not contemplated in this document, and continuous developments should be conducted in order to obtain a working prototype of this proposal

Performance Evaluation of the Managed Bandwidth Service with QoS Guarantees Christos Bouras

This paper describes a solution to extend the Managed Bandwidth Service (MBS), which is provided on a backbone network using MPLS VPNs, to non-MPLS domains and also evaluates it. It is based on the Class Based Weighted Fair Queueing mechanism (CBWFQ) [4] and describes the way it should be implemented to provide guaranteed bandwidth connections. In particular, CBWFQ can provide assured bandwidth connections when simultaneously leads to efficient bandwidth utilization. In addition, the proposed solution is being tested on simulation environment (using the Network Simulator) in order to evaluate its performance characteristics. On the simulation tests had been reserved specific amount of bandwidth for specific flows and their throughput was measured in order to understand if the proposed solution works well. Finally, the results are very well and prove that this method can guarantee bandwidth for every flow in all network conditions (congested or uncongested) . At last, the paper presents a technical example of router configuration for implementing the MBS service according to the basic proposed solution
