Object-Oriented Components for High-speed Network Programming

This paper makes two contributions to the development and evaluation of object-oriented communication software. First, it reports performance results from benchmarking several network programming mechanisms (such as sockets and CORBA) on Ethernet and ATM networks. These results illustrate that developers of high-bandwidth, low-delay applications (such as interactive medical imaging or teleconferencing) must evaluate their performance requirements and the efficiency of their communication infrastructure carefully before adopting a distributed object solution. Second, the paper describes the software architecture and design principles of the ACE object-oriented network programming components. These components encapsulate UNIX and Windows NT network programming interfaces (such as sockets, TLI, and named pipes) with C++ wrappers. Developers of object-oriented communication software have traditionally had to choose between high-performance, lower-level interfaces provided by sockets or TLI..
