Analysis of SCTP and TCP based communication in high-speed clusters

摘要: Performance and financial constraints are pushing modern DAQs (Data Acquisition Systems) to use distributed cluster environments instead of monolith one-box systems. Inside clusters application communication layers should support outstanding high performance requirements. We currently investigating different network protocols that could meet the requirements speed/low latency peer-to-peer within DAQ clusters. have carried out various measurements with TCP SCTP over Fast Gigabit Ethernet. focusing on Ethernet Technologies, because this transport medium is broad deployed, cost efficient it has much better cost/throughput ratio than other available alternatives (e.g.: Myrinet, Infiniband). During study, a protocol measurement peer components been developed. In first part paper, we give short comparison two (SCTP TCP), an introduction layer structure Later discuss results single/multi-stream communication, overview about code transition possibilities from developer point view between protocols, draw conclusions usability.
