Implementation experience with OMG's SCIOP mapping

Abstract

Longevity of distributed computing middleware standards, such as CORBA, depend on their ability to support a range of applications by providing low overhead access in a uniform manner to a large variety of platforms and network capabilities. OMG's recent adaptation of Stream Control Transmission Protocol (SCTP) mapping is another instance of this trend. Applications can obtain all the benefits of this emerging protocol via a standard compliant, distributed object model. This paper reports on integration of SCTP with Adaptive Communications Framework (ACE) [2] and The Ace ORB (TAO). [3] By exploiting network path multiplexing capability of SCTP we demonstrate that CORBA applications can bound the maximum latencies they suffer under stressful network failures to under 50 msec. © Springer-Verlag Berlin Heidelberg 2003.
