MPLS Transport Profile is gaining importance as it becomes a dominant solution for a converged transport network.In a high speed network, any disturbance over the network cause heavy data loss. When data is transferring a topology like bus or ring. The chance of data loss increases more in same ratio. In this present the discussion is being performed on high speed MPLS Ring network. As some fau...

This paper introduces a new cross layer tree-based peer-to-peer design using hierarchical cluster layers and a new method for selection of “backup parent pools” for resilient streaming of scalable video to provide highest quality of experience for all peers. Backup parent pools are selected during the process of multicast tree construction based on information provided by the hierarchical clust...

Scalability and fault tolerance become a fundamental challenge of data center network structure due to the explosive growth of data. Both structures proposed in the area of parallel computing and structures based on tree hierarchy are not able to satisfy these two demands. In this paper, we propose Totoro, a scalable and fault-tolerant network to handle the challenges by using backup built-in E...

The safety of keys is the Achilles’ heel of cryptography. A key backup at an escrow service lowers the risk of loosing the key, but increases the danger of key disclosure. We propose Recoverable Encryption (RE) schemes that alleviate the dilemma. RE encrypts a backup of the key in a manner that restricts practical recovery by an escrow service to one using a large cloud. For example, a cloud wi...

With the rapid growth of power system, it is becoming increasingly difficult to realize reach and time coordination for conventional backup protection. To cope with those problems, wide-area protection is widely researched. In this paper, a novel dynamic cooperation mechanism of wide-area protection is proposed, which can operate better than distributed and centralized systems with respect to r...

Recently P2P (Peer-to-Peer) has been proposed to improve the scalability of the traditional VoIP (voice over IP) systems. However, P2P makes VoIP service unreliable because P2P networks probably scale up and the service nodes are very likely to fail or leave the P2P networks when VoIP service is offering. To deal with this issue, we propose a service quality assurance mechanism. The whole propo...

This paper presents network coding based reliable disjoint and braided multipath routing (NC-RMR ) for sensor networks, which forms multipath by hop-by-hop method and only maintains local path information of each node without establishing end-to-end paths. Neighbors of each local node are divided into groups according to their hops to sink nodes to improve the network load balancing. For furthe...

With the ever-growing amount of data, the network bandwidth requirement has increased greatly in Remote Backup System. The network bandwidth became the bottleneck of the whole system. The paper describes the Remote Backup System using Hash to identify and avoid sending duplicate data blocks between the Primary Node and the Secondary Node, thereby, to reduce the data replication network bandwidt...
