Abstract |
|
|
| LEO satellite network plays a major role in the design of next generation internet. Due to high error rate of satellite link
and absence of error handling mechanism in TCP, the end-to-end performance of existing TCP based applications over the satellite
environment degrades substantially. Many research contributions have shown that with the help of explicit loss notification, sender
is able to discriminate between loss due to congestion and loss due packet corruption, thereby avoids the unnecessary reduction of
sending rate. Few studies, however, have mentioned that sending smaller size packets or optimum size packets can increase the success
of packet delivery. The contribution of this work is to propose an integrated solution to improve the end-to-end performance of TCP
using backward explicit notification of GSL (Ground-to-Satellite link) errors and optimum packet size calculation at TCP sender. With
help of simulation experiments, we show that proposed scheme improves the end-to-end performance of TCP based applications over
high error rate satellite links. |
