We also propose an architecture to support PoP within PDPs (Policy Decision Points originally defined by the IETF). The notion of PoP, and the proposed architecture allow the automation of the policy replacement task currently manually executed by the network administrator based on the network business plan. Keywords: policy-based network management, policy definition, policy of policies, meta-policies, policy replacement automation.

This study was conducted through the experiences of packaging Learning

This paper presents a novel protocol to support the atomic deployment of management policies for networks with quality of service (QoS) support. The necessity of such a protocol comes from the fact that faulty policy deployments lead to situations where the required QoS is ...

However, the investigations carried up to do not properly address the issue related to event notifications. The Simple Network Management Protocol, which is the widely deployed and accepted solution, has an interesting but also limited support for event notification through its trap mes- sages. In this

Today, there are no facilities available to support dynamic domains in most network management systems. This paper introduces two new languages to deal with dynamic domains. The first language is used to create new domains through the selection of managed objects. The second language, on its turn, is

It was taught a training course for teachers about the use of authoring tools to create these objects. In this training, the teachers, besides creating an LO, also answered three questionnaires, and these data were statistically analyzed. We conclude that most mathematics teachers can use and combine learning authoring tools to create LOs according to the proposed methodology.

For instance, operators and users located at different administrative domains must communicate with each other in order to configure and monitor agreed quality of service levels. This paper proposes a novel peer-to-peer (P2P) management architecture for optical networks, focused initially on the new RNP
