Transport Protocol Issues of In-Network Computing Systems
Klaus Wehrle, Ike Kunze · 2020
Today's transport protocols offer a variety of functionality based on the notion that the network is to be treated as an unreliable communication medium. Some, like TCP, establish a reliable connection on top of the unreliable network while others, like UDP, simply transmit datagrams without a connection and without guarantees into the network. These fundamental differences in functionality have a significant impact on how COIN approaches can be designed and implemented. Furthermore, traditional transport protocols are not designed for the multi-party communication principles that underlie many COIN approaches. This document discusses selected characteristics of transport protocols which have to be adapted to support COIN functionality.
