The Zephyr Notification Service

Zephyr is a notice transport and delivery system under development at Project Athena.1 Zephyr is for use by network-based services and applications with a need for immediate, reliable and rapid communication with their clients. Zephyr meets the highthroughput, high fan-out communications requirements of large-scale workstation environments. It is designed as a suite of ‘‘layered services’’ based on a reliable, authenticated notice protocol. Multiple, redundant Zephyr servers provide basic routing, queueing, and dispatching services to clients that communicate via the Zephyr Client Library. More advanced communication services are built upon this base.
