NETWORK MANAGEMENT ?NETWORK MANAGEMENT ?

Network management refers to the activities, methods, procedures, andtools that pertain to the operation, administration, maintenance, and

provisioning of networked systems.In other cases, network management involves a distributed database,

auto polling of network devices, and high-end workstationsgenerating real-time graphical views of network topology changes

and traffic analysis.

In general, network management is a service that employs

a variety of tools, applications, and devices to assist human network

managers in monitoring and maintaining networks.

NETWORK MONITORING ?NETWORK MONITORING ?

Definition : Monitoring is obtaining values for the end-to-end, link, and element characteristics. It involves

collecting data, processing some or all data, displaying the

data and archiving it.

Basically it involves collecting the data from the

network and after processing it, displaying it in desired form

and take appropriate action accordingly.

Depending up on path used :

In-Band Monitoring

Out-of-Band Monitoring

Depending on data storage :

Centralized MonitoringDistributed Monitoring


10/38

In-Band/Out-of-Band Monitoring

In-band monitoringis having the network management data

flow over the same network that the user network traffic

uses.

Out-of-Band monitoringis providing different paths for

network management data flows and user network traffic.


11/38

CentralizedCentralized MonitoringMonitoring

In centralized monitoring plan, all monitoring data radiatefrom one monitoring node using in-band or out-of-band

paths. This monitoring node is typically a host running a setof network management tools.

CENTRALIZED MONITORINGCENTRALIZED MONITORING


13/38

DISTRIBUTED MONITORINGDISTRIBUTED MONITORING

In a distributed monitoring plan, monitoring data are collected atlocalized monitoring nodes and either passed on to display and

storage nodes or processed by the monitoring node.

When the data are passed on without processing, the

monitoring node act to localize the data collection, reducing the

amounts of management data that transmit the network and possibly

providing backup monitoring capabilities in the event of a loss of

any monitoring node.

NETWORK PERFORMANCENETWORK PERFORMANCE

The Network Performance measurement is related

to measure and make available various aspects of

network performance and display them in desired

form .

BRIEF DESCRIPTION OFBRIEF DESCRIPTION OF

ROBOT CLASSROBOT CLASS

Throws:

AWTException- if the platform configuration does not allow low

level input control. This exception is always thrown when

GraphicsEnvironment.isHeadless() returns true.

SecurityException- ifcreateRobot permission is not

granted

java.awt

Class Robot

java.lang.Object | +-java.awt.

Robot public class Robot extends Object

This class is used to generate native system input eventsfor the purposes of test automation, operation related to

screen system, and otherapplications where control of

the mouse and keyboard is needed.

SPECIAL FEATURES ANDSPECIAL FEATURES AND

ADVANTAGESADVANTAGES

Live image viewing :Live image viewing :

Advantageous over log based system because live watching andimmediate action can be performed.

Advantageous over proxy server because it not only catch everyaction for internet but also any other actions such as game

playing in lab time.

Platform Independency :Platform Independency :

Since on a network , users can use different operating system. Weare implementing in Java to fulfill this requirement.

SPECIAL FEATURES ANDSPECIAL FEATURES AND

ADVANTAGESADVANTAGES

Specially for College Lab:Specially for College Lab:

This project is very useful from our labs point of view becauseteachers can watch every action of students live

what they are actually doing,

how much work they have completed and

Giving instructions to a single student or to all the students.

No such software available :No such software available :

To the best of our knowledge and search on net.

except few like Netvizor & Anyplace control
