الملخص الإنجليزي

An Overlay network is a virtual network implemented on top of a physical network.

The use of overlay networks has been suggested as an alternative solution that can provide additional services that do not exist in the underlying network, such as controlling the routing infrastructure, increasing network security, and reducing duplicate messages through multicast.

To get end-to-end Quality of Services (QoS) in the internet, Service Specific Overlay Networks (SSONs) has been designed to deliver media in heterogeneous environments.

A single SSON is built to meet each user service requirements.

The increase in complexity and heterogeneity of these networks, changing conditions in the network and different types of faults that may occur, renders their control and management more difficult.

Therefore, self-healing concept was introduced to handle these changes and assure highly reliable and dependable network system performance.

Self-healing is a property that allows a system to perceive whether it is working properly or not.

In addition it makes the necessary adjustment that can automatically restore the services affected by a failure in a manner that is seamless to the end user. In this thesis, a novel self-healing architecture for autonomic SSONs is presented.

The proposed self-healing architecture targets applications that involve multimedia delivery services and are designed to meet user requirements.

These services are realized using overlay networks.

A service consists of a Media Client (MC) that requests the service, a Media Server (MS) that provide the service, and a set of Media Ports (MPs) that are used to process the multimedia data along the end-to-end path.

Our proposed solution is uses new approaches for monitoring, diagnosing and recovering of services thus achieving self-healing.

Moreover, two novel algorithms were proposed to realize the proposed architecture functionality.

The proposed algorithms take into account the dynamic nature of SSONs.

They probe the dynamic changes of overlay members where a MP may fail, leave, or join the network.

Simulation has been conducted to test the validity of the proposed algorithms.

Results show the efficiency and validity of our approach in term of disruption time and how they are effective in terms of success rate, and network load.
