Title : Operational Reliability for EDIINT AS2 Authors : John Duker Dale Moberg Filename : draft-duker-as2-reliability-15.txt Pages : 11 Date : 2014-04-22 Abstract: One goal of this document is to define approaches to achieve a "once and only once" delivery of messages. The EDIINT AS2 protocol 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.
