THE USE OF OPNET TO SIMULATE QoS CAPABILITIES OF CISCO 2600
SERIES MODULAR ROUTERS
Simulation of my project in 7 aspects
1)Baseline: it does not provide any form of QOS
2 )FIFO: First In First Out- It revels the effects of the queuing mechanism at the IP layer
3) Priority Queuing (PQ)- effect of the PQ on the packets.
4) Custom Queuing (CQ)-this method was used in networks where the minimum service is needed to be guaranteed:
5) Custom Queuing with LLQ- Advancement or extension of the previous Custom Queuing
6) WFQ- Weighted Fair Queuing Provides bandwidth for traffic queues.
7) WFQ with LLQ- this is the advancement of WFQ
8) CAR disabled/enabled (Committed Access Rate): This will impacted on busy or congested networks.
The first seven simulations are based on first design of the network. That design developed on the base of the OPNET.
The last simulation Committed Access Rate will be developed on the base of second design.
First Application: In this application i took our university labs as reference and designed the application. The main objective of this application is to evaluate The main aim of the project is to examine and compare different configurations which will enable the most effective configuration for a given situation concerning the issues involved in this technology.
Design objects of first application is
1) Four workstations
2) Two 32 port switches
3) Two 2600 series routers
4) Client servers
5) Application config
6) Profile config
7) 10 Base T links
1) WEB USERS.
2) DATABASE USERS.
The simulation scenarios of my application designs and Simulations will demonstrate the effects on IP traffic such as:
Traffic dropped (packets per second)
- Video Conferencing
- Packet end to end delay
- Traffic sent
- Traffic received
- Point to Point
- Queue delay
Second Application: In this application i took our university labs as reference and designed the application. The main objective of this application is to evaluate The main aim of the project is to examine and compare different configurations which will enable the most effective configuration for a given situation concerning the issues involved in this technology.
Evaluating the design and examining the delay of the packets when the fire wall is set in the design Part.
Design objects of second application is
1) Three workstations
2) 32- port switches
4) Cisco 2600 series routers
5) Client server
6) Application config
7) Profile config
By the first design it reveals that delay of the packets has been possible to the network with the use of firewall in the design.
This is the design for CAR service .which revels the how qos can be implemented with the minor changes of the CAR service
Simulation scenarios for second application
Committed Access Rate (Enabled/Disabled)
- IP Traffic dropped
- Token Ring Delay
- Video Conferencing End to End delay
- CAR IP Traffic dropped
