Abstract:
One goal of this document is to define approaches to achieve a "once
and only once" delivery of messages. The EDIINT AS2 protocol [AS2] is
implemented by a number of software tools on a variety of platforms
with varying capabilities and with varying network service quality.
Although the AS2 protocol defines a unique "Message-ID", current
implementations of AS2 do not provide a standard method to prevent
the same message (re-transmitted by the initial sender) from reaching
back-end business applications at the initial receiver.
A second goal is to reduce retransmissions and failures when AS2 is used
in a synchronous mode for transmitting MDNs. There can be a large
latency between receipt of the POSTed entity body and the MDN response
caused by the operations of decompressing, decrypting, and signature
checks. Uncoordinated timeout policies and intermediate devices dropping
connections have interfered with reliable data exchange. The use of an
HTTP 102(Processing) status code is described to mitigate these
difficulties. Use of these reliability features is indicated by
presence of the "AS2-Reliability" value in the EDIINT-Features header.
Intended Status
The intent of this document is to be placed on the RFC track as an
Informational RFC.
