Link-Security™ Software Demo 1

This demonstrates TCP offloading onto the IPU.

Before you begin

Make sure that you have:

Installed a Napatech IPU in a server. See Installing a Napatech IPU.
Programmed the IPU with an appropriate FPGA image. See Napatech Link-Security™ Software FPGA Images.
Compiled and installed Link-Security™ Software on the IPU. See Installing Napatech Link-Security™ Software on the IPU.
Configured the IPU. See Configuring the IPU.
Configured the test server. See Configuring the Test Server.

About this task

Demo setup showing that traffic is not encrypted, and reverse-proxying is performed on the IPU.

In this demo, traffic is not encrypted, and reverse-proxying is performed on the IPU.

Note: The following prompt is used to indicate which part of the system to run the provided commands on.

test#: The server where the test script is executed.

Procedure

Run the test script.

For example:

test# cd /opt/ipu_workload_tls/src
test# python3 -m standalone.main --proxy soc --deploy-run -c 2000

where:

--proxy soc: Run reverse-proxying on the IPU.
--deploy-run: Deploy network/services and run workload.
-c 2000: 2000 connections that the wrk tool uses.

This command deploys network infrastructure and run the wrk tool.
