NETWORK ENGINEERING
NETWORK ENGINEERING is the process concerned
with engineering and optimizing the most
cost-effective design for routing calls within a
network based on load forecasts and other rules
to be employed
10

NETWORK MANAGEMENT
  • OBJECTIVE OF NETWORK MANAGEMENT
  • To maximize the utilization of available
    facilities in order to meet customer services
    demands
  • When necessary, to inhibit traffic that is
    causing abnormal conditions (faults).

11

NETWORK MANAGEMENT
  • BENEFITS OF NETWORK MANAGEMENT
  • Increased revenue due to higher call completion
  • More effective use of the network capabilities
  • Improved service
  • Improved customer / public relations

What to do in NMC
  • Monitor traffic flow between DIVNET Switched
    Network and Non DIVNET Switched Network
  • Implement Network Control to provide the best
    network performance when problem occur
  • Analyze Network Performance
  • Provide Company Performance Evaluation to telecom
    company rating the performance
  • Manage Network Trouble Reporting

21

Network Management Tools
  • Real Time Network Management System that provides
    Surveillance, Analysis, Control and Monitoring of
    the switches
  • Network Operations procedures Guidelines that
    ensure all task especially when there is a very
    complicated process
  • Network Performance Evaluating System

22
JOB DESCRIPTION NETWORK SURVEILLANCE

Roles
  • Monitor traffic flow between DIVNET calls and
    between
  • DIVNET exchanges to/from Non DIVNET Networks
  • Implement Network Controls to optimize network
    performance when network anomalies occur
  • Responsibilities
  • Minimize call block in the long distant network
  • Manage and optimizing the existing network
  • Ensure the traffic data accuracy

23
JOB DESCRIPTION NETWORK SURVEILLANCE
  • Tasks
  • Perform network surveillance for DIVNET network
    elements that comprise DIVNET switched network
  • Analyze real time network management data to
    identify abnormal network condition
  • Implement network control(s) when network
    anomalies occur that affect the performance of
    the network carrying DIVNET calls
  • Generate network performance report

24
JOB DESCRIPTION NETWORK SURVEILLANCE
  • Tasks
  • Isolate reefer network troubles to appropriate
    work group
  • Supply data to network performance management
    group
  • Serve as Central Point of Contact for information
    on the performance of the DIVNET Switched Network
  • Develop preplans and coordinate activation of
    predefined activities. Includes mass calling
    events and special events that impact the
    performance of the DIVNET Switched Network

PEAK DAY -- SURVEILLANCE STRATEGY

1. MONITOR FINAL ROUTE OVERFLOW
2. MONITOR IDLE CAPACITY
3. MONITOR SWITCH HEALTH
27

FACILITY FAILURE --SURVEILLANCE STRATEGY
SYMPTOMS ARE 1. HIGH OR 100
OVERFLOW ON SEVERAL ROUTES

LOOKS FOR 2. CONGESTION IN SWITCHES
3. IDLE CAPACITY AROUND FAILURE 4.
HARD - TO - REACH CODES 5. SOURCE OF
THE PROBLEM
28

SWITCH FAILURE --SURVEILLANCE STRATEGY
SYMPTOMS ARE 1. MACHINE CONGESTION
MESSAGES 2. 100 OVERFLOW ON ROUTES
TO SWITCH 3. NO DATA FROM SWITCH

LOOKS FOR 4. CONGESTION IN OTHER
SWITCHES 5. IDLE CAPACITY AROUND
SWITCH 6. HARD - TO - REACH CODES
29

FOCUSED OVERLOAD SURVEILLANCE STRATEGY
SYMPTOMS ARE 1. LOCALIZED SWITCH
CONGESTION 2. HIGH PRESSURE AND OVERFLOW INTO
REGION
LOOK FOR 3. CAUSE OF PROBLEM 4. HARD - TO
REACH CODES
30

NATURAL DISASTER SURVEILLANCE STRATEGY
DISASTER AREA
SYMPTOMS ARE 1. REGIONAL SWITCH
CONGESTION 2. HIGH PRESSURE AND
OVERFLOW INTO REGION

LOOKS FOR 3. CAUSE OF PROBLEM 4. HARD -
TO - REACH CODES 5. IDLE CAPACITY
OUT OF REGION
