SLA-BASED NETWORK MANAGEMENT- Application in a Wireless Environment -
This thesis contributes to the SLA-based network management approach at different levels. First, a language for specification of the service level agreement (SLA) is proposed, which offers friendly-interfaces to model and specify the SLA and the high-level objectives, as well as a formal and comprehensible notation for target network equipments in order to configure them suitably. Then an adaptive mapping mechanism which translates system-level policies into equipment-specific configurations is proposed, with control and monitoring tools that enable adaptability against the environment changes. Finally, an actual put into practice of all the concepts related to the SLA-based network management is realised through a real use case. We apply our session-based quality-of-service management architecture (SQoSMA) which integrates all the elements of the specification of SLAs and the policies, to guarantee the quality of the Voice over WLANs (VoWLANs) services. We propose and integrate two techniques in our architecture which do not require any modification of the MAC (Media Access Control) layer, in order to overcome the VoWLANs services issues, which are the low number of VoIP calls in the IEEE 802.11 Wireless LANs, and the negative effect of the new call addition when the WLAN reaches its maximum capacity. In order to measure the performance of our solution, a complete test-bed was implemented; it included all architecture 'SQoSMA' elements, VoIP tools, Resource Management (RM), SIP and integration components. Performance evaluation demonstrates the feasibility of our solution, and the benefit in terms of the number of assured VoIP sessions. Another important result is that the choice of the VoIP sessions targeted by control actions, which represents a high-level objective, is completely configurable. Although explained with 802.11b, the proposed scheme can be applied to any 802.11 network that needs to assure a number of VoIP calls within the given bandwidth allocation.
