With the development of computer science, desktop virtualization technology is more and more popular. In virtualized desktop, it is a very significant research to share periphery devices in the client-end computer seamlessly. We implement a device sharing mechanism to extend the universal serial bus in client-end host to the network for server-end host using transparently. This virtual device bus...
Peer-to-Peer SIP is proposed to leverage Peer-to-Peer computing to control multimedia sessions in a decentralized manner. A lot of companies can be benefited if conventional SIP environment does not require the configuration and maintenance of central servers. However, existing P2PSIP systems put too much emphasis on the decentralization of SIP elements and the briefness of distribution. To some extent,...
Development of Internet brings the great increasing communication requirement. This demand impels the developing progress of Voice over Internet Protocol (VoIP). It is difficult to supply the high quality user experience for VoIP services, which has brought great challenges to VoIP developer because of the dynamic property of Internet. We obtain the following results in lots of existing VoIP systems:...
When extending peer-to-peer live streaming system to IEEE 802.11-based wireless network, service guarantee for inter-domain movement is an obstacle since IEEE 802.11 has no QoS maintenance mechanism for it. The stream system must consider it itself. As a peer roams among adjacent networks, the streaming service will be interrupted by the disconnection of wireless network path and IP address changes...
During the development of a distributed application, programmers usually involve many programs. These programs have different IP addresses and different ports. Sometimes, they even have a same port. For instance, in P2P environment, peers usually use the same port to communicate with each other. We often need tens of computers to develop such a distributed application. Unfortunately, not each one...
