“…In the area of distributed systems, the existing configurable operating systems again are not fine grain enough to allow efficient customization (e.g K42 [2], Choices [8]). Moreover, these projects pre-define the overall structure of an operating system, prohibiting migration between capability and capacity designs.…”

In the context of high-end computing systems, general-purpose operating systems impose overhead on the applications they support due to unneeded services. Although dedicated operating systems overcome this issue, they are difficult to develop or adapt. In this paper, we propose a framework, based on the component programming paradigm, which supports the development and adaptation of such operating systems. This framework makes possible the a la carte construction of operating systems which provide specific highend computing system characteristics.

“…Choices is an object-oriented multiprocessor operating system written in the C++ programm.ing language (Stroustrup [1986)). In Choices all system entities and resources (such as disks, processes, files, memory maps and so forth) are objects, with various frameworks specifying interactions among objects within and across different subsystems (Campbell [1992]). The word framework is used in the sense that building a framewerk involves designing software components that operate together.…”

The Network Interface Framework (NIF) is an object-oriented software architecture for providing networking services in the Choices object-oriented operating system. The NIF supports multiple dient subsystems, provides clients with low-latency noti:fication of received packets, and imposes no particular structure on clients. By contrast, traditional BSD UNIX-style networking does not meet the last tworequirements, since it forces clients to use software interrupts and queueing. BSD UNIX cannot accomodate a process-based protocol subsystem such as the z-Kernel, whereas the NIF can. We have ported the zKernel to Choices by embedding it into the NIF. Using the standard z-Kernel protocol stack with NIF yields Ethernet performance comparable to BSD networking. The NIF is also flexible enough to support services that cannot easily be supported by traditional BSD, such as quality-of-service for multimedia. Preliminary performance results for asynchronous transfer mode (ATM) networks show that the NIF can be used to minimize jitter for continuous media data streams in the presence of non-realtime streams.

“…Other approaches involved creating an operating system built from a complex object-oriented framework, such as in the Choices [5] or Taligent [15] work. Although such efforts have been influential in other OS projects, such as Spring, they do not appear to have been widely used.…”
