The performance of the SNR protocol is studied when it is implemented for end-to-end flow and error control and the efficiency with which this protocol uses the network bandwidth and its achievable throughput is evaluated as a function of certain network and protocol parameters.Abstract:
The performance of the SNR protocol of A. N. Netravali et al. (1990) is studied when it is implemented for end-to-end flow and error control. Using a combination of analysis and simulation, the efficiency with which this protocol uses the network bandwidth and its achievable throughput is evaluated as a function of certain network and protocol parameters. The protocol is enhanced by introducing two windows to decouple the two functions of receiver flow control and network congestion control. This enhancement and the original protocol are compared with go-back-N (GBN) and one-at-a-time-selective-repeat (OSR) retransmission procedures, are shown to have significantly higher throughput for a wide range of network conditions. As an example, for a virtual circuit with 60-ms roundtrip delay and 10/sup -8/ bit error rate, in order to deliver 500 Mb/s throughput, both the GBN and OSR require a raw transmission bandwidth of approximately 800 Mb/s, whereas SNR with two windows needs slightly higher than 500 Mb/s raw bandwidth. Periodic exchange of state can also provide a variety of measures for congestion control in a timely and accurate fashion. >read more

Reliable multicast transport protocol (RMTP)
TL;DR: Since lost packets are recovered by local retransmissions as opposed to retransmission from the original sender, end-to-end latency is significantly reduced, and the overall throughput is improved as well.

Characteristics of scalability and their impact on performance
TL;DR: Different aspects of scalability are attempted, such as structural scalability and load scalability, which are the ability of a system to expand in a chosen dimension without major modifications to its architecture.

Methods for transmitting data
TL;DR: In this article, the authors proposed a multi-pass data transfer technique that requires only negative acknowledgements to be sent by the recipients. But the number of recipients which can receive the data from the source can be greatly increased by using a "negative acknowledgement collection" scheme whereby "replication points" (preferably routers) collect individual negative acknowledgments and forward them as a unit to the next level.

Throughput performance of transport-layer protocols over wireless LANs
TL;DR: The results identify the mechanisms affecting end-to-end performance when retransmissions are used to get better error performance on a link, and quantify the increased load on the link due to competing retransmission strategies.
