Real-time Support in COM

摘要

While there has been substantial work on real-time CORBA to offer real-time support in a distributed heterogeneous environment with standard real-time middle-ware, comparatively less work has been done to investigate sup-port for real-time applications in COM, the direct competitor of CORBA. In this paper, we examine the COM technology and explore the possibility of providing real-time sup-port in COM. We argue that real-time COM should pro-vide a policy specification interface between the application and the underlying (real-time) operating systems that is as declarative as possible, and we conclude that COM can be extended to provide various real-time support services through this interface. We shall discuss an experimental prototype targeted for real applications along the line of our proposal.
