High Performance Web Services Bandwidth Challenge Discovery UDDI Description WSDL Packaging XML DSTP Transport SOAP/HTTP SOAP+ Network Protocol TCP SABUL/UDT *Open DMIX is an open source collection of web services for data mining, data integration and data exploration
SABUL/UDT Protocol Overview • Uses both Rate Control (RC) and (window based) Flow Control (FC) • Constant RC interval to remove RTT bias • Employs bandwidth estimation • Selective acknowledgement (ACK) • Reduces control traffic & results in faster recovery • Uses packet delay as well as packet loss to indicate congestion • Slow start • controlled by FC
UDT Fast, Fair & Friendly, Easy & Efficient Friendly to TCP Flows Fair to other High Perf. Flows Fast Efficient
