faults in computer networks may result in millions of dollars in cost. faults in a network need to be localized and repaired to keep the health of the network. fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. in this paper, we propose a novel approach based on imperialist competitive alg...

The protection of network infrastructure and services is one of the main issues network managers face today. This paper investigates this matter through the study of network resilience. A resilience factor (RF) is proposed to take into account topological aspects of the network and also the amount of traffic losses under stress conditions. The proposed factor is evaluated using a real network b...

With the continuous promotion of high and new technologies such as computers big data, humans enter a period-information age. Mass data information can be transmitted exchanged online through network. In recent years, research on image encryption based optical processing technology is becoming more favored by researchers. this regard, study will focus algorithms in images realize fractional Fou...

When a computer network grows larger and adds more services offered by different providers, each user may have to keep many keys for different services. Incorporating smart card technologies and master key concept, this letter proposes an efficient scheme to solve the key management problem in such multiservice environments.

Nowadays, the rapid development of computer networks calls for highly distributed management technologies that aim at integration and automation. This paper then gives an overview of current management architectures for computer networks, and tries to apply P2P technologies to make up existing limitations in term of performance, scalability, flexibility, maintainability and reliability. Due to ...
