B.E. INFORMATION TECHNOLOGY
FOURTH YEAR SEMESTER VII
SUBJECT: ADVANCED COMPUTER NETWORKS
(ELECTIVE-I)
Lectures: 4 Hrs per week
Practical: 2 Hrs per week
Theory: 100 Marks
Term Work: 25 Marks
Oral: 25 Marks
Objectives: In first part, advanced technologies like High speed Devices etc. are to be
considered. Second part Network programming is to be studied. Not just SOCKETS but also
protocols, Drivers, Simulation Programming. In third part we should study Network Design,
Protocols designs and analysis considering deterministic and non-deterministic approach. We
expect natural thinking from student. For example he should able to consider different
constraints and assume suitable data and solve the problems.
Pre-requisites: Computer networks
