Abstract :
When large files are offered by many mirrors for clients to download, selecting the proper download mirrors is necessary in speeding up the clients´ download. The existing method, which measures all the Round Trip Time (RTT) between clients and all mirrors, costs much time and Internet traffic. In this paper, we propose NC-APT, an efficient and scalable download mirror selecting system, which is capable to provide clients an efficient method to select quick download mirror. NC-APT is scalable because it only requires the mirrors to response to ICMP ping instead of keeping running an NC software program. Our experimental results show that NC-APT significantly improves the clients´ download rates with slight cost of time and Internet traffic.
