Improving the SLA-based management of QoS for secure multimedia services

This paper proposes to integrate security parameters into the Service Level Specification (SLS) template proposed in the Tequila project to improve SLA-based management of QoS [8], [21]. Integrating those parameters in the QoS part of the Service Level Agreement (SLA) specification is essential in particular for secure multimedia services since the QoS is negotiated when the multimedia service is deployed. Security mechanisms need to be negotiated at deployment time when sensible multimedia information is exchanged. In this paper we show that including security parameters in the SLA specification improves the SLA-based management of QoS and therefore the negotiation, deployment and use of the secure multimedia service. The parameters this paper proposes to integrate have the advantage to be understandable by both the end-users and service providers. © IFIP International Federation for Information Processing 2005

Policy-Based Quality of Service and Security Management for Multimedia Services on IP networks in the RTIPA project

This paper summarizes the research work that has been conducted in the context of the RTIPA project on policy-based QoS (Quality of Service) and security management for distributed multimedia services. It presents an architecture allowing the derivation of policies from the service level down to the network level. It is a step towards an end-to-end QoS and security management for distributed multimedia services running on the new generation of IP networks
