Applications

In this directory, there are several applications that can be used throughout this course project.

Traffic generator

The traffic generator is used to send traffic between different hosts in the Mininet. Here is the instruction to run the traffic generator

sudo ./apps/send_traffic.py --trace ./apps/trace/XXX.trace --topo xx/topology.json

This command will replay the traffic defined the trace file. The trace file is generated by the trace genrator, which will be described later.

Note that this script requires sudo previledge. Without it the script will crash. In case the script fails, please use the following command to guarantee that the script is killed completely.

sudo ./apps/kill_traffic.sh

To learn more about the traffic generator, please read [traffic_generator/README.md].

Trace generator

The trace generator define the traffic to be played in the Mininet. There are two types of traffic that can be defined: iperf traffic and memcached traffic.

• The iperf traffic can be either tcp and udp, which transmits random data using the full bandwidth, with best effort.
• The memcached traffic contains small-sized read/write requests for key-value stores. The traffic contains small packets, one packet per request.

To learn more about how to use the trace generator, please read [trace/README.md].
