A Novel Self-Similar (S~2) Traffic Filter to Enhance E-Business Success by Improving Internet Communication Channel Fault Tolerance

摘要

Internet traffic patterns can cause serious buffer overflow in electronic business (e-business) systems. This leads to widespread retransmission that prolongs the service roundtrip time (RTT). As a result customers are unhappy and avoid returning to do more business. The previous Real-Time Traffic Pattern Detector (RTPD) was proposed to improve Internet channel fault tolerance. With RTPD support time-critical applications can identify the traffic patterns and invoke the corresponding measures to neutralize their ill effects in a dynamic manner. The extant RTPD, however, cannot detect self-similar traffic. This inspired the development of the novel self-similarity ( S~2 ) filter proposed in this paper, which makes the RTPD capability more complete. The "RTPD + S~2 " package is the enhanced RTPD or ERTPD package. The test results indicate that the addition of the S~2 mechanism can indeed contribute to improved e-business communication channels over the Internet.
