Book Description
The Stream Control Transmission Protocol (SCTP) is a relatively young transport protocol that was originally designed to transfer SS7 signaling messages over packet switched networks but has since been standardized for general use. It provides many attractive characteristics not found in current dominant protocols like User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) and shows promising performance metrics. This thesis focuses on SCTP's retransmission mechanisms and how they're affected by network conditions, providing insight into optimization opportunities. For this purpose a research platform is presented that enables rapid prototyping of new algorithms and fast turnover of performance data. The platform is then used to verify previous SCTP research and will be used to reduce the often large learning curve of Linux Kernel development. Finally we present a novel algorithm for dynamically determining the optimum Retransmission Time Out Minimum (RTOmin) value of an SCTP association that significantly improves performance while avoiding spurious retransmissions.

Book Description
Although multihomed communication is a rapidly emerging trend for next generation networks, no known book explores multihomed communication with the Stream Control Transmission Protocol (SCTP). Filling this void, Multihomed Communication with SCTP (Stream Control Transmission Protocol) explains this innovative feature that allows an endpoint to sim

Book Description
In this book we have shown what others have done in regard to enhancing SCTP's retransmission time-out performance, and how their approaches are different from ours. We have also shown how the Adaptive RTO algorithm helps improve the SCTP's performance in contrast to the existing implementation. Significant amount of data were gathered in order to show that we have improved the transfer rate in SCTP by about 5%, in the scenario where the Adaptive RTO algorithm is implemented. We have been vigilant in making sure the Adaptive RTO algorithm does not unnecessarily clog network's bandwidth, and that the current implementation of RTO MIN can be safely replaced with the Adaptive RTO algorithm. Furthermore, we have done extensive testing of the Adaptive RTO algorithm in respect to multiple scenarios.We have also shown that the Adaptive RTO algorithm does not clog network's bandwidth under any conditions. This is an evolutionary research. This book does not solve all the problems but sets up additional studies and hypothesis.

Book Description
In this paper, we propose an early retransmission scheme to improve TCP's performance in delivering time-sensitive media. Our extensive ns2 simulations show significant improvement. When integrated into a traditional TCP variant, namely TCP-SACK, the early retransmission scheme can substantially reduce the latency caused by retransmission timeout. As a result, it can help TCP-SACK achieve a considerably higher success rate in delivering real time media. Early Retransmission also enhances the performance of a delay-based TCP variant, namely PERT. Furthermore, we also explore the improvement brought by employing a fine-grained retransmission timer, and compare it with ER. We find out that ER outperforms the fine grained timer in a variety of conditions and the combination of the two can further improve performance.

Book Description
We derive expressions for remotes procedure call (RPC) retransmission timeout values that minimize the weighted sort of total elapsed time, operating system kernel costs, and network charges. Currently we select RPC retransmission timeouts to minimize network utilization, an operating point chosen with our networks' low bandwidth in mind. When public utilities provided digital service becomes popular, we will routinely make requests to servers across town and across nation and we will pay for each message that we send. These networks may offer various grades of service, each with different loss and delay characteristics. In such an environment, choosing the retransmission timeout and grade of service that minimize our costs is not obvious. Our approach, illustrated with a simple RPC algorithm, can be applied to other remote invocation mechanisms. We can incorporate the expression for the optimal retransmission timeout that our approach generates into the communication's software of distributed operating
