pathChirp is an active probing tool for estimating the available bandwidth on a communication network path. Based on the concept of "self-induced congestion," pathChirp features an exponential flight pattern of probes we call a chirp. Packet chirps offer several significant advantages over current probing schemes based on packet pairs or packet trains. By rapidly increasing the probing rate within each chirp, pathChirp obtains a rich set of information from which to dynamically estimate the available bandwidth.

学习vb是做的几个游戏。饿罗撕方块， 扫雷，等等。。。 对学习vb,和初学游戏编程的朋友一定很有帮助 -study done a few games. Hungry Romanian tear chunks and mine, and so on. . . Vb learning, and learning games programming certainly helpful friends
