Architecture of subject
Subject includes three chapters:
Chapter 1: Introduction about network system of Hutech University, problem of
Hutech network system, solution to resolve.
Chapter 2: Chapter 2 includes three parts.
Part 1: Overview about MPLS, architecture MPLS packet, operation of MPLS
network, command line for configure MPLS operation.
Part 2: Overview about QoS, architecture of QoS, classification, marking and
queuing tool.
Part 3: QoS over MPLS, relative about IPP, DSCP and MPLS EXP, DiffServ with
IP packet and MPLS packet, DiffServ tunneling mode, steps implement QoS over
MPLS network.
Chapter 3: Network design and implement. Deploy QoS over MPLS, get result
and define of develop in subject.
