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

Topology With 4 Hosts (I)

Latency Data ( ~173 ms )

Topology With 4 Hosts (II)

Latency Data (~154 ms)

Topology With 6 Hosts (I)

Latency Data (~546 ms)

Topology With 6 Hosts (II)

Latency Data (~ 183 ms )

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.

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.

First Step: Deployment of Controller

Second Step: Creating Topology View

Third Step: Transfer Topology View from C1- C2
