Overview
Project Title	Update Asynchronous Message Service Specification
Approval	Draft
Document Number	735.1-B-2
Charter	6.09 Delay Tolerant Networking Working Group
Document Type	Blue
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.
Applicable Patents	There are no patent issues for this technology that are known by the CCSDS community
Patent Comments	N/A
Survey of Similar Standards Documents or Projects Undertaken in Other Bodies and elsewhere in CCSDS	Other message exchange systems exist (CORBA, JMS, etc.), but none are engineered for operation in a delay-tolerant network environment.
