Untersuchungen zum Einsatz von Low-Level Protokollen bei der Rechnerkommunikation in heterogenen Netzwerken

When ist is up to determine the protocol for coupling two computers, it is quite always TCP/IP, since only TCP/IP is supported by nearly all kind of computers and an all net media. Unfortunately, TCP/IP comes with a considerable protocol overhead, which has a negative impact an both bandwidth and latency of the data flow rate. In order to use network specific low-level protocols instead, a modular software library has been developed, using low-level protocols for ATM and Myrinet and a gateway process, using this library, has been implemented as well. Afterwards, performance of this library was measured and compared with that of conventional TCP/IP socket communication. The result is presented and discussed in this paper
