Security-Enhanced Quality of Service (SQoS): A Network Analysis
Security and Quality-of-Service (QoS) issues have traditionally been considered separately, with different objectives and implementation architectures. No protocol has been designed and implemented so far to parameterize security as a QoS parameter. However, it has been noted recently that security and QoS are highly intertwined; security mechanisms may severely affect QoS mechanisms in terms of network performance and data confidentiality. In addition, users are not given the choices on which security services and mechanisms as well as which security level should be applied to their traffic.
