Sažetak
In our paper we propose efficient tool to predict possible traffic congestions caused by contracting of a new SLA (Service Level Agreement). It could be an important part of admission control process in SLA creation (DiffServ networks). Naturally, it is off-line algorithm and we can use it only through negotiation process (SLA creation), just to ensure better QoS end-to-end routing in the moment of service invocation. The problem is seen as an expansion problem of link capacities in given limits for given traffic demands (SLAs). Such explicit traffic engineering technique provides the possibility to intelligently tailor the route such that different parts of the network remain equally loaded. It helps to avoid the creation of bottleneck links on the path and maintains high network resource utilization efficiency. Also, it is capable to consider the impact of end-to-end delay on network resource provisioning, in the moment of SLA creation.
