Step 6: Explore Networks Inside the Cloud—SDN
Cloud computing defines network resources as needing to be “rapidly provisioned and released with minimal management effort or service provider interaction” (Mell & Grance, 2011), As cloud networks developed, it was clear that further virtualization of network devices such as switches and routers was needed.
This led to what is known as software-defined networking (SDN) technology, enabling programmatic interfaces to control functions of these devices. You know that it will be important for management to understand how SDN supports cloud deployments like BallotOnline’s, so it will be a key part of your technical report.
Instead of manually programming network devices to configure a LAN, cloud management systems using SDN can set these devices up to forward packets to particular destinations by “calling” SDN APIs (application programming interfaces – libraries of software routines). This allows for the creation of virtual networks in the cloud by software.
The most popular SDN standard is OpenFlow by the Open Networking Foundation. OpenFlow switches include SDN controllers, which maintain flow tables to control forwarding of IP datagrams, and they can learn routes as IP packets when particular source and destination addresses arrive.

CCA625 Project 1 Step 7To demonstrate your understanding how network packets are transmitted in the cloud, you will use Mininet, a popular open-source network simulator that can be used together with Wireshark. This demonstration will be part of your technical report. Follow the steps in this Simulating a Network Using Mininet and Analyzing Packets Using Wireshark Guide.
During the lab, you will provision an EC2 instance in AWS using a preconfigured AWS Machine Image (AMI) and use the Mininet simulator in the EC2 instance to create two hosts. You will then use Wireshark to capture the packet exchanges.
You will prepare a lab report as per the lab guide and attach it to your final technical report.
