RtpLossDetect

RtpLossDetect is a small series of scripts / programs that can help you detect packetloss in your network using RTP as baseline protocoll.

Installation

Programs need Golang with pcap and Python3

# rtpgen needs golang and golangpcap for sniffing packets
sudo apt-get install  golang 
sudo apt-get install  golang-github-akrennmair-gopcap-dev/stable
cd rtpgen
go build

# rtpgen / rtpgenrcv needs python3
sudo apt-get install python3

# loss.sh needs tc - traffic control part of iproute2
sudo apt-get install iproute2

Usage

Please, before use read the differenet scripts. Get to know them.

Modify rtpgen.py with the right vars

Setup - Send side

# On the send side
# RTP packet generator parameters
source_port = 11337
destination_port = 21338
destination_ip = "192.168.10.146"  # Replace with actual IP
payload_size = 160
packet_interval = 0.02

Setup - RCV Side

# On the rcv side - edit rtpgenrcv/start.sh - set the right vars
PORT=21338
NIC=wlan0

Usage

# Start generating packets
python rtpgen/rtpgen.py

# Simulate loss
bash rtpgen/loss.sh 1%

On the rcv side

# After setting the right vars in start.sh
bash rtpgenrcv/start.sh

start.sh will generate output if it detects packetloss from the rtpgen. E.g. if sequence number in rtp stream does not add up.
