ELEC5517: Software Defined Networks

Background

an example of a tree network topology having two levels of switches and a fanout of three (3).

Task 1:

I. Create a topology showing these industries in a network controlled by the ISP. Please avoid exchange of information amongst these industries.

II. Send HTTP amongst nodes and capture the OpenFlow packets. Analyse the captured packets for each industry and show possible similarities and differences of the results.

III. Show and assign the bandwidth paths to these industries based on the properties below:

a. Voice network

b. Data network

c. Integrated voice and data network

Task 2:

I. Read access

II. Write access

III. Read and write access

IV. Show the similarities between the results I, II and III above.

Task 3:

topology, two industries are allowed to communicate with each other while the third industry should not be able communication with the others. Bandwidth paths are equal across all the switches. Below is an example of a sliced topology based on the Figure 1.

Perform the following tasks based on the new sliced topology:

I. Implement the customised topology using ONOS as the controller.

II. Use ONOS flow endpoint API to achieve isolation of the third industry from the rest of the network.

III. Display and analyse flow statistics at each of the edge switches using ONOS flow statistics end point API.

IV. Using host endpoint API please add a new host to edge switch s4.

Task 4:

Based on the requirements, we are required to achieve the following requirements through P4 language.

I. Drop the NetFlow once the IP equals to h1.

II. Enable the IPV4 forwarding function.

III. Increase the survivability in IP headers (TTL)
