We present an Internet-scale network topology information (NTI) service named WIND for localizing P2P traffic. Central to WIND are the two simple ideas: 1) obtaining NTI directly from routing infrastructures, and 2) leveraging existing, widely deployed DNS caches for NTI delivery. WIND fulfills the fidelity, flexibility and scalability requirement of an effective NTI service. WIND is deployed in CERNET...
Packet forwarding prioritization (PFP) in routers is one of the mechanisms commonly available to network operators. PFP can have a significant impact on the accuracy of network measurements, the performance of applications and the effectiveness of network troubleshooting procedures. Despite its potential impacts, no information on PFP settings is readily available to end users. In this paper, we present...
As the IPv6 networks rapidly deployed, the transition problem has been changed. Because the transition of applications is a steady process with a far longer duration in comparison to the transition of infrastructure, providers cannot give up the duty of serving IPv4 traffics for the time being. On the other hand, operating a dual-stack backbone is highly costing for large-scale deployment of new networks...
