Abstract
Today's applications are becoming increasingly diverse in their
communications service requirements and are increasingly driving the
development and adoption of new protocols to accommodate them.
Unfortunately, deploying new protocols is a difficult and expensive
process. One reason is the high cost of developing, testing, and
installing protocol implementations. To reduce this difficulty,
protocols are developed and executed within environments called
protocol subsystems and protocol software is often ported instead of
being coded from scratch. Unfortunately, differences among today's
protocol subsystems often reduce the portability and re-usability of
protocol code and, therefore, present barriers to the deployment of
new protocols. In addition, current subsystems and protocol
architectures lack sufficient flexibility and extensibility to support
the dynamic addition and adoption of new protocols necessary to
accommodate the burgeoning growth of Web-based applications.
This work considers approaches for providing protocol subsystem
support for flexible and efficient communication services. It first
assesses the effects that protocol subsystems have on protocol
portability and performance. It then focuses on making existing
protocol subsystems more flexible by proposing two different
approaches, each optimized for a different situation, that allow
protocol code implemented in one subsystem to be used without
modification within other subsystems, and thus, reduce the barriers to
protocol deployment. This work then examines the use of Java as an
implementation and execution environment for protocols and protocol
subsystems. Lastly, this work identifies why current environments
limit the degree of flexibility and extensibility available to
protocol programmers and presents a new protocol subsystem optimized
for flexibility, extensibility, and configurability based on the
provision of communication services by protocol-function composition.
