Order-Worker-Entry: A System of Patterns to Structure Communication Protocol Software

We present a system of architectural design patterns for the implementation of flexible, extensible, and maintainable application tailored network protocol software in end-systems. The pattern system mainly follows a vertical structuring approach. Outsourced De-Multiplexing reduces cross-talk between different protocol sessions. Data-Path Reification assures service extensibility and quality of service control for protocols. Data Path Partitioning assures the re-usability of protocol components and allows for easy modification and configuration. Data Path Classification enables application and network to flexibly interact with a protocol environment without compromising the protocol’s autonomy.
