Will the topology of the network changed dynamically in the test?

[Estraie]

I.e. are there addition/modification/deletion of links/hosts/switches after network has been built?

Or, whether we are required to implement the dynamical modification of the flow table?

[EricLee543]

Yes. You need to consider situations where the network topology changes dynamically. The project also asks you to provide a complex testcase to demonstrate the robustness of your program. You can consider this dynamically changing situation

[Estraie]

Then whether we need to consider the complexity of these operations?

[EricLee543]

The data of the test cases are not very large. No need to consider time complexity
