Abstract Advanced network applications such as remote instrument control, collaborative environments, and remote I/O are distinguished from \\traditional" applications such as videoconferencing by their need to create multiple, heterogeneous ows with di erent characteristics. For example, a single application may require remote I/O for raw datasets, shared controls for a collaborative analysis system, streaming video for image rendering data, and audio for collaboration. Furthermore, each ow can have di erent requirements in terms of reliability, network quality of service, security, etc. We argue that new approaches to communication services, protocols, and network architecture are required bothtoprovide high-level abstractions for common ow types and to support user-level management of ow creation and quality. We describe experiences with the development of such applications and communication services.
