Constant Bandwith Server (CBS) for Linux

Description

Keywords:	Real-Time, QoS, Resource Reservation, Linux
Description:	This component implements a resource reservation scheduler. The algorithm is based on the Constant Bandwidth Server (CBS) algorithm [Abe98]. However, we modified and extended the original algorithm to take into account several practical issues. In our implementation, a server can handle more than one task; an automatic reclamation mechanism [Lip00] can be optionally activated; bandwidths can be tightly bounded through a self suspension mechanism. All these features are currently available on a single software module and they can be enabled/disabled through conditional compilation.
