Abstract
An ad hoc middleware workshop was held at the International Center
for Advanced Internet Research in December 1998. The Workshop was
organized and sponsored by Cisco, Northwestern University's
International Center for Advanced Internet Research (iCAIR), IBM, and
the National Science Foundation (NSF). The goal of the workshop was
to identify existing middleware services that could be leveraged for
new capabilities as well as identifying additional middleware
services requiring research and development. The workshop
participants discussed the definition of middleware in general,
examined the applications perspective, detailed underlying network
transport capabilities relevant to middleware services, and then
covered various specific examples of middleware components. These
included APIs, authentication, authorization, and accounting (AAA)
issues, policy framework, directories, resource management, networked
information discovery and retrieval services, quality of service,

security, and operational tools. The need for a more organized
framework for middleware R&D was recognized, and a list of specific
topics needing further work was identified.

Introduction
This document describes the term "middleware" as well as its
requirements and scope. Its purpose is to facilitate communication
between developers of both collaboration based and high-performance
distributed computing applications and developers of the network
infrastructure. Generally, in advanced networks, middleware consists
of services and other resources located between both the applications
and the underlying packet forwarding and routing infrastructure,
