Eclipse/BSD – an operating system which is the basis for testing the Quality of Service (QoS) that is being developed at the Information Sciences Research Center at Bell Labs, Lucent Technologies. Eclipse/BSD is based on FreeBSD version 3.4., and is compatible with FreeBSD, supporting the same system calls, protocols, drivers and applications.
The system developers have implemented hierarchical proportional share cpu, disk and link schedulers, the /reserv file system providing an API to manipulate “reservations” and a tagging mechanism for the association of reservations with schedulable operations.
Eclipse/BSD is being used to guarantee QoS to server applications, and in particular to differentiate the performance of different web sites hosted on the same platform.
The demand to provide Quality of Service (QoS) guarantees is increasing with the need to run multiple server applications, such as audio and video media servers and web servers, and host services for multiple entities (e.g., companies, individuals) on the same platform. QoS requirements may be client-based, service-based, contentbased, and so on.
