Prerequisites and assumptions

Read this section carefully and make sure you have everything that is needed.

Necessary packages

The following applications must be installed on all virtual machines hosting the solution.

OS	Application	Installation
Ubuntu/Debian	docker engine + docker-compose	sudo apt install docker -y && sudo apt install docker-compose -y
Ubuntu/Debian	wget	sudo apt install -y wget
CentOS/RHEL	docker engine	sudo yum install docker -y
CentOS/RHEL	docker-compose	curl -L https://github.com/docker/compose/releases/download/v2.7.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose && chmod 755 /usr/local/bin/docker-compose
CentOS/RHEL	wget	sudo yum install -y wget

Docker Installation on Ubuntu 24.04

Update apt:

apt update -y

Add the Docker repositories:

apt install ca-certificates curl gnupg -y

install -m 0755 -d /etc/apt/keyrings

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
chmod a+r /etc/apt/keyrings/docker.gpg

echo \
    "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
    "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
    sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

Update apt again:

apt update -y

Install the docker utilities:

sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

Create a Docker group if none was created:

sudo groupadd docker

Add your user to the Docker group

sudo usermod -aG docker <user_name>

In order for the changes to take effect, you either need to close and open a new terminal or logout and login again into your account.

The Docker Version 2 will now be installed. The docker-compose command will now become docker compose, and this new command should be used during the installation of the Latencetech solution.

Minimum hardware requirements

The following hardware requirements need to be met for the solution

HOST	CPU	RAM	SPACE
QoS-agent	1	Memory footprint : 20 Mb Recommended RAM : 40 Mb	Image size on disk : 40 Mb Recommended disk : 50 Mb
Reflector	1	Memory footprint : 10 Mb Recommended RAM : 20 Mb	Image size on disk : 27 Mb Recommended disk : 40 Mb
Analyzer (small)	1	Memory footprint : 2.32 Gb Recommended RAM : 4 Gb + 0.1 Gb by agent	Image size on disk : 9.95 Gb Recommended disk : 20 Gb
Analyzer (medium)	2	Memory footprint : 2.32 Gb Recommended RAM : 8 Gb + 0.1 Gb by agent	Image size on disk : 9.95 Gb Recommended disk : 50 Gb

Analyzer configuration

• Small configuration supports between 1 and 20 QoS-agents.
• Medium configuration supports between 1 and 150 QoS-agents.

Reflector's host ports to be opened

The following ports need to be exposed on the host running the reflector docker:

Latency measurement	Protocol	Port(s)
ICMP	ICMP	Icmp ports
HTTP	TCP	12080
HTTP with SSL	TCP	12443
TCP	TCP	12023
UDP	UDP	12024
TWAMP	TCP	12862
TWAMP	UDP	12800 to 12819

Other measurements	Protocol	Port(s)
Traffic capacity	TCP, UDP	12501
LIFBE	TCP, UDP	12550
Packet Loss Test (udp)	TCP, UDP	12555

Analyzer's host ports to be opened

The following ports need to be exposed on the host running the analyzer dockers:

Docker	Protocol	Port(s)
Kafka zookeeper	TCP	12092
Grafana	TCP	12021
Influx	TCP	12086
API	TCP	12099
