Abstract

Wireless packet-switched IP networks have transport-layer problems due to their shared-medium nature. Bandwidth variation, changes of the bandwidth available for a connection throughout its lifetime, is a major acute problem. A number of factors may cause the connection's bandwidth variation. Change in the number or activity volume of other connections sharing the same bandwidth resource (e.g. the same time slot/s in GPRS networks), the narrowing/widening of the total bandwidth dedicated to data users (e.g. the start/end of voice calls in GPRS networks), and radio-link optimizations due to SNR changes (as in HDR) are significant factors in bandwidth breathing. Failing to properly respond to those changes will result in the transport protocol either underutilizing the scarce wireless bandwidth or overflowing the network. We describe WBST (Wireless Boosted Session Transport), Flash Networks' patented transport protocol, applying bandwidth estimation techniques, and present experimental results obtained both from a wireless-link emulator and from a live GPRS network, showing that WBST significantly outperforms TCP.
