ASSIGNMENT

Individual

Modelling Gigabit Ethernet Backbone Network with Wireless Extension using OMNET++

1.   Developing a Network Model: In this assignment you will develop a Gigabit Ethernet (use 10 GbE switch) backbone network model using OMNET++ . For wireless technologies, use 802.11ax (Wi-Fi 6) technology. You are required to complete the assignment by investigating the following five scenarios.

•   Scenario 1: 90 wired video clients (no wireless clients ->100% wired network)

•   Scenario 2: 70 wired and 20 wireless video clients

•   Scenario 3: 50 wired and 40 wireless video clients

•   Scenario 4: 30 wired and 60 wireless video clients

•   Scenario 5: 90 wireless video clients (no wired clients)

2.   Subnet: Your Backbone GbE (Choose 10 GbE switch) can be connected to several subnets (e.g.  1 GbE  Ethernet switches).  Let us assume that each subnet can support  up to 20 clients/nodes for an optimum network performance. So, if you are simulating a network with 100 clients, your network model should have a total of 5 subnets (20 clients/subnet) linked to the GbE backbone.

3.   Network configuration/parameter setting and simulation  results: Configure the above five scenarios in turn and measure the following performance metrics.

(a) Video Throughput

(b) Video end-to-end delays

(c) Video packet losses

4.   Simulation validation and comparative analysis: Validate simulation results and summarise your findings. You may use the following table to summarise your results.

5.   Simulation parameters

•   Total number of clients: 90

•   Simulation time: 3600 Sec (longer required for Video streaming)

•   Traffic type: Video streaming

•    Packet type: UDP packet

•    Performance metrics:

(a) Video Throughput.

(b) Video end-to-end delays.

(c) Video packet losses.

6. In your report, answer/address the following questions.

Video streaming uses  UDP transport  layer  protocol,  and  hence  UdpVideoStreamClient, UdpVideoStreamServer can be used for video client and video Server, respectively.

a)   UdpVideoStreamClient:   Explain  the   purpose/function   of  “ UdpVideoStreamClient” (Hint: Explain the technical details and usage of this command).

b)   UdpVideoStreamServer: Explain technical details and usage of this command.
