Objectives
Programme
· Introduction to Internet Traffic Theory
- Basics of traffic modeling and performance evaluation
- Traffic characterization at packet level by point processes
- Burst and correlation measures
- Poisson and renewal processes
- Advanced traffic models
- Introduction to fractal traffic theory
- Measurements and simulations
· Internet Traffic Management
- Overprovisioning and managed bandwidth
- Streaming and elastic traffic characteristics
- Traffic control: open and closed loop control methods
- Packet and burst level congestion
- Connection admission control methods and traffic dimensioning:
- Peak Rate Allocation
- Rate Envelope Multiplexing
- Rate Sharing
- Future internet design principles
· Traffic measurements and modeling of internet applications
- Application traffic models (web, P2P, gaming, VoIP, etc.)
- Identification of peer-to-peer traffic
- Gaming traffic analysis (case study: World of Warcraft)
- VoIP traffic analysis (case study: Skype)
· Performance evaluation of TCP
- Measurements of TCP, metrics, and faireness
- Performance models of TCP
- Adaptive queue management methods
- Evolution of TCP and high-speed TCP versions
- Loss- and delay-based TCP
The course is concerned with introducing the students to the
theoretical tools to carry out performance evaluations of infocommunication systems. It also
gives practical case studies how to apply these tools.
