Introduction Theoretical Framework Implementation Findings and Conclusions

Overlay networks

A network built on top of one or more existing networks

Add extra functionality

Introduction Theoretical Framework Implementation Findings and Conclusions

OSPF / SDN comparison

Open Shortest Path First (OSPF) :

Mature protocol

Widely used and supported

Uses Dijkstra’s algorithm

Used by Compute factory

Software Defined Networking (SDN):

Separation between control plane anddata plane

Centralized managment

Programmability

Routing granularity

Introduction Theoretical Framework Implementation Findings and Conclusions

Hypothesis

If the created overlay networks make use of SDN (OpenFlow), Compute factory’scontrol loops that observe and modify the behavior can gain benefits.

Conclusions

Increase stability in data transfer

Dicrease jitter

Balance the CPU load in intermediate switches

Not increase network utilization
