2. Part 1: Latency Analysis
Objective:
To analyze the relationship between the type of
topology deployed and the latency measured
from h1 to h4 (h1: CORE-CL-1; h4: EDGE-TR-1)
Constraints:
ü The location of h1 and h2 must be the same
among all topologies
ü The total number of hosts in one topology
should be the same as the other

3. Topology With 4 Hosts (I)

4. Latency Data ( ~173 ms )

5. Topology With 4 Hosts (II)

6. Latency Data (~154 ms)

7. Topology With 6 Hosts (I)

8. Latency Data (~546 ms)

9. Topology With 6 Hosts (II)

10. Latency Data (~ 183 ms )

11. Analysis
— There seems no direct relationship
between the latency and the topology
deployed.
— In such sense, it is hard to conclude which
topology is better than the other.
— Further study should be conducted for the
benefit of deeper understanding.

12. Part 2: Dynamic Deployment of
Controller
Objective:
To reduce the workload handled by the
original controller.
Constraints:
For simulation purposes, the threshold
imposed on the number of hosts is 3.
