The main focus of the training is to provide the attendees with the tools and techniques for the improvement and optimization of the performance of mobile backhauling and core network. The course explains the most relevant backhauling architectures and technologies. It develops the methodology to dimension backhauling and core network links for both classical and next-generation mobile services.

Today most operators are interested in providing all services over a converged IP backbone. They also see big benefits in shifting to next-generation network (NGN) technology. The dimensioning of both core network and backhauling for the transport of QoS-aware multimedia applications has a strategic importance, but it is challenging. The main objective of this course is to provide practical methods to size core network and backhauling links and nodes, in order to achieve the required QoS objectives in end-to-end network paths. From this course, participants can learn how to apply in practice the most recent advances in network calculus to size their networks and assure QoS. The course will also give a perspective on the mobile backhauling architecture and technology.

After attending this course, participants will be aware of the critical issues related to dimensioning core network and backhauling links for QoS-oriented services. Network planners will be able to employ methods to predict the performance of network segments and to deploy the correct amount of resources, given the quality constraints of multimedia services and applications. The course will provide the latest achievements in the most advanced network calculus techniques, from a practical and methodological standpoint.
