Abstract
This paper presents JECho, a Java-based communication infrastructure for
collaborative high performance applications. JECho implements a
publish/subscribe communication paradigm, permitting distributed,
concurrently executing sets of components to provide interactive service to
collaborating end users via event channels. JECho's efficient
implementation enables it to move events at rates higher than other
Java-based event system implementations. In addition, using JECho's eager
handler concept, individual event subscribers can dynamically tailor event
flows to adapt to runtime changes in component behaviors and needs, and to
changes in platform resources.
JECho has been used to build distributed collaborative scientific codes as
well as ubiquitous applications. Its event interface and eager handler
mechanism have been shown flexible and in some scenarios, critical to the
successful implementations of such applications. This paper's
micro-benchmarks demonstrate that, with optimizations and customizations of
the runtime system and the object transport layer, TCP-based reliable group
communication in Java can reach good performance levels. These benchmark
results also suggest that it is viable to use JECho to build large-scale,
high-performance event delivery systems. JECho's implementation is in pure
Java. Its group-cast communication layer is based on Java Sockets, and it
also runs in some embedded environments that currently lack standard object
serialization support.
