Toward the P2P topology mismatch problem, we proposed a novel P2P service re-directing scheme and it is fully described in reference. Furthermore, we have successfully implemented this mechanism in EPON system. Experimental results show that our scheme can effectively reduce core network traffic, and evidently improve clients' downloading rate.
SIP provides powerful capabilities for building audio conferencing services. However, the scalability for SIP-based telephony systems is mainly limited by both the capability of server and the availability of bandwidth. Based on the study of the SIP and P2P protocol, the paper proposes a pure hierarchical P2P architecture for SIP-based telephony systems. The architecture can dynamically increase the...
This article presents an approach to delivering qualitative end-to-end quality of service (QoS) guarantees across the multiprovider Internet. We propose that bilateral agreements between a number of autonomous systems (ASs) result in the establishment of QoS-class planes that potentially extend across the global Internet. The deployment of a QoS-enhanced border gateway protocol (BGP) with different...
