Adding Security to QoS Architectures

Book chapter, 2004

In a Quality of Service (QoS) aware communication system, a user is able to choose between various service classes, each with different reliability, predictability, and efficiency degrees. However, until now security has not been recognized as a parameter in QoS architectures and no security-related service classes have been defined. This implies that users have no chance of configuring their level of security, which is remarkable. This paper contains a survey of QoS architectures as seen from a security point of view and gives some initial ideas on how QoS architectures can be extended with a security dimension.
