Objectives and Contents
This course covers advanced topics in computer networks, with a blend
of theoretical and practical topics. On the theoretical side, the
syllabus will cover mathematical foundations of networking, including
discussions of queuing theory, information theory, simulation, and
optimization. Each theoretical topic will be presented together with
an application in networking (e.g., random walks, network design,
traffic engineering). On the practical side, the syllabus will cover
concepts and designs related to modern network architectures and
technologies (e.g., data-center networks, software-defined networks,
data plane programming), and protocols at various levels (e.g.,
HTTP/2, IPSec, MPLS, DCTCP). Students will gain hands-on experience
with topics discussed in class through a series of exercises using
network simulators and emulators.
