The paper describes a system to manage the distribution of multimedia content over IP with the support of QoS and fine grained access control. It relies on visual languages to simplify the specification of complex access control and QoS policies in distributed multimedia streaming services. QoS is based on the RSVP protocol, whereas access control is provided based on the RBAC model. In particular, the system translates the visually specified policies into the XACML format, which also embeds the QoS parameters that will be successively used in RSVP negotiations. © 2006 by Knowledge Systems Institute Graduate School.

Abstract
The paper describes a system to manage the distribution of multimedia content over IP with the support of QoS and fine grained access control. It relies on visual languages to simplify the specification of complex access control and QoS policies in distributed multimedia streaming services. QoS is based on the RSVP protocol, whereas access control is provided based on the RBAC model. In particular, the system translates the visually specified policies into the XACML format, which also embeds the QoS parameters that will be successively used in RSVP negotiations. © 2006 by Knowledge Systems Institute Graduate School.
