Course Objective
This document proposes an outline for the graduate level course on Network Management offered
as an elective for the Master of Engineering students in the Department of Electrical and
Computer Engineering at Ryerson University.
The subject is approached with an introduction and overview of Network Management models
such as the TCP/IP, OSI, and TMN models. The course then focuses mainly on the TCP/IP-based
Internet Management including SNMP protocol, Agent architectures, Structure of Management
Information (SMI), Management Information Base (MIB), and FCAPS (Fault, Configuration,
Accounting, Performance, and Security) management. The course will also introduce and discuss
in detail advanced topics such as the Policy-Based Network Management, Distributed
Management, Service Management Architectures and Wireless Device Management. In policybased management, the course will explain how policies are used, architectural principles
governing such systems and open policy models such as the DEN (Directory Enabled
Networking). In distributed management, the course will focus on the distributed network
management applications where the main communication mechanism for monitoring and control
is SNMP.
The course requires students to engage in detailed study of the IETF proposed standard MIBs
such as the MIB-II, SNMPv3 MIBs including VACM, USM, Target, and Notification MIBs,
Distributed Management MIBs (defined by the IETF Distributed Management Working Group),
and RMON2. Student will be involved in SNMP Agent/MIB implementation using an open
source extensible agent toolkit. Students are expected to apply the knowledge gained from this
course to configure and customize commercial Network Management Systems such as the HP
Openview Network Node Manager (http://www.openview.hp.com) and an open source agent
toolkit such as the Net-SNMP (http://www.net-snmp.org) as part of their individual/group course
project.
Course Prerequisite
A thorough understanding of the data communication principles and Internet TCP/IP protocol
suite is required.
