Introduction

TRE-PRO: a new in-network TRE architecture that leverages the power and flexibility of emerging programmable switches to provide on-path detection and elimination of redundant traffic transmission in the networks. In TRE-PRO, a pair of nodes in a routing path cache packets to reduce bandwidth consumption and gain performance revenue. Each pair of cache nodes in the networks maintains per-pair synchronized cache stores to accurately encode and decode the on-the-fly traffics.

We implement TRE-PRO prototype in P4 language for BMv2 simple_switch target for proof of concepts.

NOTE: Due to the privacy issue for sharing real network traffic traces provided by UPC's Broadband Communication Research Group, in the next test scenario, we provide generated dataset (Src/Dst request distiribution: zipf dist., Payload data: Amazon food review data).

How to run?

Testbed setup

1. Download dataset

wget http://snap.stanford.edu/data/finefoods.txt.gz
gzip -d finefoods.txt.gz

2. Create files for test and compile codes

./setup.sh

Run test script

Reduction ratio

To run test, simply do:

./run_tests.sh

This script generates packets according to a Zipf distribution with different skewed parameters(0.4 - 0.8) and calculates reduction ratio.

You can see the test results through this command line.

python show_result.py

Clean up the test

To delete all build files, and logs:

./clear.sh
