Feature interaction has been first formally identified as a problem in the telecommunication domain. With the rapid growth and application of Web Services, feature interaction problem also arises in the dynamic Web Service interactions. Race conditions, one type of functional feature interactions in Web Services, will lead to the unexpected system behavior(More)
Multiparty video conferencing (MPVC) facilitates real-time group interaction between users. While P2P is a natural delivery solution for MPVC, a peer often does not have enough bandwidth to deliver her video to all other peers in the conference. Recently, we have witnessed the popularity of one-view MPVC, where each user only watches full video of another(More)
This paper studies one of the inter Radio Access Technology (RAT) voice call handover schemes from Long Term Evolution (LTE) to circuit core system. Single Radio Voice Call Continuity (SRVCC) is used to achieve full coverage of voice service in the edge of LTE network during the early stage of Evolved Packet System (EPS) network deployment. In order to(More)
Video streaming is one of the most popular applications in today's networks, ranging from communications to entertainment, it penetrates into every aspect of our lives. Service providers concern more and more about Quality of Experience perceived by end user. This paper proposes a new model to evaluate the end-to-end video quality in LTE networks.(More)

In current Internet applications, naming is constructed by the location of host and the resource in the host, and name resolution mapping system is constructed by a treelike domain name system (DNS). These architectures has some shortcomings, such as not supporting data migration and replication, vulnerable to Denial of Service (DoS) attacks. Researchers(More)
With the popularity of virtualization, the problem that how to manage hundreds even thousands of virtual machines running on multiple physical computing nodes becomes important. Current virtual machine management systems only can obtain basic information of virtual machines and execute simple operations on them, such as start, reboot and shutdown. In this(More)
