Project Title

Update Asynchronous Message Service Specification



Document Number



6.09 Delay Tolerant Networking Working Group

Document Type


Description of Document

The service and its protocol implement an architectural concept of asynchronous exchange of relatively brief messages. Under this concept, the modules of mission systems may be designed as if they were to operate in isolation, each one producing and consuming mission information without explicit awareness of which other modules are currently operating.
