BMv2 Code for Purdue CS590 Final Project Demo:

Applying P4 switch as the cache of Key-Value Store

Presentation slides: link

Get Started

This code can be compiled and loaded as a bmv2 application. Testing the code requires bmv2 installation and mininet environment.

Install Environment

Download the VM image with preinstalled p4c and bmv2 environment from here and boot the VM.

Config the Test Environment

To change the network topology in mininet, edit the configuration file ./pod-topo/topology.json.

To modify the match-action rule installed in bmv2 switch when creating the environment (only have one switch in default topology), edit the configuration file ./pod-topo/s1-runtime.json.

Test the code

After booting the VM, Move the folders into ~/tutorials/exercises.

Under ~/tutorials/exercises/<folder name>, prompt

make run

then basic.p4 will be compiled and the mininet environment will be set up.

In the mininet CLI, prompt

xterm h1
xterm h2

to open virtual host h1 and h2's CLI window.

For the host acting as a KVStore server, prompt

./kVStore.py

and the Key-Value Store server will start and print the received packets.

For the host acting as a client, prompt

./send.py <destination IP> (read|write) <key> <value>

to send the packet.

To observe the packet sent and received by client, open the new xterm window and prompt

tcpdump udp --nnvvXSs 1514

to monitor all UDP packet traffics.
