SNADS or Systems Network Architecture Distribution Services is an "asynchronous
distribution service that can store data for delayed delivery."
SNADS uses
SNA data links to allow messages and objects to be sent from system to system using the
APPC protocol. It is a very robust service: once an object has been accepted by SNADS it will get to its destination. If the communication link is unavailable (down), the transmission will be held on the sending system until the link is available, at which time it is sent. If the transmission is interrupted, it will be resumed or re-sent once the communication problem is resolved.
SNADS is available on several IBM platforms, including
