AT&T/Neda's Efficient Short Remote Operations (ESRO)
Protocol Specification Version 1.2
Status of this Memo
This memo provides information for the Internet community. It does
not specify an Internet standard of any kind. Distribution of this
memo is unlimited.
IESG Note
This protocol has not had the benefit of IETF Working Group review,
but a cursory examination reveals several issues which may be
significant issues for scalability. A site considering deployment
should conduct a careful analysis to ensure they understand the
potential impacts.
Abstract
This document specifies the service model, the notation and protocol
for Efficient Short Remote Operations (ESRO). The ESRO service is
similar to and is consistent with other Remote Procedure Call
services. The emphasis of ESRO service definition and the ESRO
protocol is on efficiency. ESRO is designed specifically with
wireless network (e.g., CDPD) usage in mind.
ESRO protocol provides reliable connectionless remote operation
services on top of UDP (or any other non-reliable connectionless
transport service) with minimum overhead. ESRO protocol supports
segmentation and reassembly, concatenation and separation as well as
multiplexing for service users (applications).
ESRO allows for trade-offs between efficiency and reliability by
specifying both 2-way hand-shake and 3-way hand-shake based protocols.
Encoding mechanisms for presentation of the parameters of remote
operations are outside the scope of this document. But,
identification (tagging) of the encoding mechanism in use (e.g., XDR,
Banan, et. al Informational [Page 1]
RFC 2188 ESRO September 1997
BER, PER) is supported by ESRO protocol.
A variety of applications can use the ESRO protocol. Some early
applications using ESRO include efficient short message submission and
delivery, credit card authorization and white pages lookup.
