An overview of the VMTP transport protocol

Communication in modern distributed systems demands low-latency transaction-oriented communication rather than stream-oriented communication as in the past. The performance and functionality of current standard transport protocols has become a major limitation in the move to higher-speed networks and larger-scale, more sophisticated distributed systems. An overview is presented of the versatile message transaction protocol (VMTP) developed to address these limitations. The authors then present measurements of VMTP performance in actual use in the V distributed system, showing that its performance matches their objectives
