Abstract
In a distributed object system such as Distributed Component Object Model
(DCOM) [5, 7], legacy transport protocols used for communication limit the performance
over high-speed networks. By making use of a low-latency, high-bandwidth, and low overhead
user-level networking architecture such as Virtual Interface (VI) Architecture [8, 18]
this performance bottleneck can be significantly reduced. Since user-level networking
architectures provide low-level primitives, the challenge lies in integrating them into
high-level applications. This requires a systematic approach. In this paper, a methodology
to utilize VI Architecture to improve the performance of DCOM using custom object
marshaling is developed. Initial experimental results demonstrate that the latencies of
small messages in distributed object computing can be significantly reduced by this
methodology.
