In recent years, the technology of Cloud Computing has been developed rapidly. It makes IT infrastructure available as a service through the network. Using Cloud Computing, users can find a new effective solution for building systems and applications according to their demands. How to make the existing services reliably run on the cloud platform, and satisfy the high scalability and availability requirements...
With the development of cloud computing, the resource management in cloud environment and flexible adaptation of services are becoming more and more important. In this paper, we design and implement a resource management system of multimedia conference based on cloud from the perspective of service provider. Media adaptation layer and automatic deployment in management system improve resource utilization...
Web cache is considered as an efficient mechanism to reduce network traffic and origin servers load. It aims to keep close to users the most popular web objects. And the performance of a Web cache always depends on the replacement strategy it chooses. In view of these, we are devoted to propose and implement a Web cache based on the LRU replacement algorithm in this paper. To improve the performance...

Internet protocol version 6 (IPv6) has significant advantages over Internet protocol version 4 (IPv4), however it will take a long time to transit from IPv4 to IPv6. Most studies on peer- to-peer (P2P) are based on a single Internet protocol (such as IPv4). And there is no effective method to achieve the communication between IPv4 peers and IPv6 peers in IPv4 and IPv6 coexistence network. This paper...
