Design and Optimization of Networks

Learning Outcomes

The course presents principles and methodologies on the design, evaluation and optimization of networks and services, complementing the basic knowledge of architecture, protocols and functions of communication networks.

Upon successful completion of the course, the students will be in position to:

  • follow and utilize the approach of top-down network design, that is most commonly encountered on medium to large scale networking projects
  • understand and evaluate alternative design options at every stage of data networks design, (e.g. requirement and specification definition, logical and physical design, selection of appropriate technologies and protocols, addressing and naming of network devices, implementation, testing and optimization)
  • select and propose proper architectures, network technologies, protocols and politics, depending on the design, upgrade and/or optimization of the network at hand
  • implement, control and readjust solutions on new or redesign existing network projects
  • run and operate routing protocols simulation software and packet sniffing software

Course Contents

  • Introduction to the design and performance evaluation of networks and services.
  • Modelling and topological design of communication networks.
  • Modelling of network services traffic and work load.
  • Top-down network design under service requirements and various constraints.
  • Selection of most appropriate link, network and transport layer protocols.
  • Selection of most appropriate network architecture and network devices.
  • Network optimization techniques and algorithms, network reliability.
  • Performance measures.
  • Quality of service assurance.
  • Theoretical exercises and network design projects.

Network Management

Learning Outcomes

After the successful completion of this course, the student will have an overview of the methodologies, techniques, technologies and protocols to monitor, manage, control, optimize performance and design of computer networks. The student will be able to propose solutions for the initial design, expansion and upgrade of computer networks in the context of specific business objectives and technical requirements/problems. Also, he will be able to monitor the realization of specific technical requirements through service level agreement (SLA). During the laboratory practice, the student exercises to monitor and control the operation of remote network elements with the utilization of specific protocols.

Course Contents
