The Evolution of Internet-Scale Event Notification Services

Adam Rifkin and Rohit Khare

WISEN Talk, 13 July 1998

Event-Based Integration has been championed as an ideal coordination technique for loosely-coupled systems. Over the last two decades, event notification services have evolved within hosts (as kernel, graphical user interface, operating system, and object-oriented runtime events), within local area networks (as tool integration, remote procedure call, networked windowing system, and distributed file system lease events), and within wide area networks (as telepresence, interactive simulation, network management, and workflow events). Emerging generations of these collaborative applications now need to span organizational boundaries - and require event notification mechanisms that scale to the Internet. This implies more than adapting to wide area networks' space and time scales: successful Internet-scale services will have to be evolvable, decentralized, secure, and reliable within an imperfect network.
