IVOA Recommendation: VOEvent Transport Protocol Version 2.0
Alasdair Allan, Robert B. Denny, John D. Swinbank

TL;DR
This paper formalizes a TCP-based protocol for transmitting transient celestial event descriptions in astronomy, providing a standardized method to facilitate consistent and reliable event distribution across the community.
Contribution
It introduces a formalized, standardized TCP-based protocol for VOEvent transportation, serving as a reference for compliant implementations.
Findings
Protocol has been in use for several years within the community
Defines network topology for event distribution
Provides a reference for implementation
Abstract
The IVOA VOEvent Recommendation defines a means of describing transient celestial events but, purposely, remains silent on the topic of how those descriptions should be transmitted. This document formalizes a TCP-based protocol for VOEvent transportation that has been in use by members of the VOEvent community for several years and discusses the topology of the event distribution network. It is intended to act as a reference for the production of compliant protocol implementations.
