Topic: Latency Study & Dynamic Deployment of Controller Presenter: Zhen-Yuan Bo Date: Dec 16, 2015
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
