In this proposal, we review the history of message communication and survey the present broadband deployment. We believe networks in 21st centry are optical networks due to fiber’s inherent data carrying capacity. To overcome the mismatching between the electrical processing speed and the optical transmission rate, an all-optical data path needs be maintained. We investigate the design issues o...

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 fault occurs over the network it will return heavy data loss. In this work we are defining some new low cost hardwar...

In a typical distributed storage system, metadata is stored and managed by dedicated metadata servers. One way to improve the availability of distributed storage systems is to deploy multiple metadata servers. Past research focused on the active/standby model, where each active server has at least one redundant idle backup. However, interruption of service and loss of service state may occur du...

Dynamic Parallel Schedules (DPS) is a flow graph based framework for developing parallel applications on clusters of workstations. The DPS flow graph execution model enables automatic pipelined parallel execution of applications. DPS supports graceful degradation of parallel applications in case of node failures. The fault-tolerance mechanism relies on a set of backup threads stored in the vola...

In this paper, we present an interconnection structure, called the balanced hypercube, which is a variation of the standard hypercube with desirable properties of strong connectivity, regularity, and symmetry. The proposed structure is a special type of load balanced graph designed to tolerate processor failure. In balanced hypercubes, each processor has a backup (matching) processor that share...

This paper divides the execution process of command post system into four stages: information acquisition, processing, decision control and response execution. It combines multilayer complex networks with a phased-mission system. Most studies have only evaluated reliability systems. evaluates optimizes In order to improve mission success rate maximize system, this provides multitasking node cri...

The PBFT (Practical Byzantine Fault Tolerance, PBFT) consensus algorithm, which addressed the issue of malicious nodes sending error messages to disrupt system operation in distributed systems, was challenging support massive network nodes, common participation over all mechanism would lead increased communication complexity, and arbitrary selection master also inefficient consensus. This paper...

Wireless technology is a promising solution for providing communication facilities to rural areas. We consider a network deployment with long-distance wireless links between rural locations. One of the network locations consists of a wired connection/communication, to connect the other locations to the Internet. We call this location the central node. Towers and antennae are used for setting up...

We propose a new approach exploiting the failure risk (node, link or Shared Risk Link Group) structures to enhance the backup path computation. Upon failure, our approach classifies the backup paths into two categories: operative backup paths and inoperative backup paths. An operative backup path is an active backup path which really receives traffic of some affected communications while an ino...

Internetworking the mobile ad-hoc networks (MANETs) with the Internet has been a hot issue for many years. However, most researches have been concentrated on the use of MANETs as the access networks for the Internet. This paper introduces another use of MANETs: backup or load-balancing transit networks for the Internet. Although the MANETs capacity is currently low compared with other backbone ...
