PG: a novel scheme to distinguish bursty packet loss from random loss in heterogeneous network

In this paper, we propose a PG scheme. PG is a group of packets, which consists of more than two packets sent back to back with no delay between consecutive packets. The packets sent in such a fashion are not only for transmitting the data, but also for probing network state. Through this scheme, the bursty packet loss can be discriminated from the random packet loss at the receiver in the wired/wireless heterogeneous network. The experiments are conducted in the emulated heterogeneous network, and the results show that this scheme works well and efficiently.
