Laboratory practice is a fundamental aspect of computer network learning. Experiments tend to be very specific, frequently demanding changes in the local network topology and privileged access to the operating system configuration. These features impose a specific and exclusive laboratory for network teaching experiments. However, it is not always possible(More)
SLA management approaches typically adopt provisioning strategies based on aggregate traffic in order to support end­to­end delay requirements of applications. They do not take into account individual flows needs in terms of delay. However, this delay can be very higher than the one observed by aggregate traffic, causing an important impact in network(More)
This paper presents a framework for representing and distributing access control policies in distributed heterogeneous systems. Access control polices follows the RBAC (Role Based Access Control) model proposed by the NIST. The framework is based on the provisioning strategy defined by IETF, i.e., the RBAC information is represented in terms of a PIB(More)
