How to simulate packet loss in Linux?

       Experiment the performance of several protocols, the flexibility of applications and network efficiency on not much perfect network criteria through simulating packet loss in Linux which is considered as a beneficial practice. To present packet loss for these simulations in an autonomous way, Linux offers various models and tools. Network simulation platforms like Network Emulation (netem) and Traffic Control (tc) are the tools which are highly implemented for this work:

Using tc and netem for Packet Loss Simulation

       The tc tool permits you to handle the network traffic flowing internal and external of your system and it is a portion of the iproute2 package in Linux. To offer Network Emulation capacities, netem is an element of tc and it presents replication, delay, packet loss and others by adding its strength. We suggest you a simple direction on the process of simulating packet loss with the help of netem and tc effectively:

Step 1: Verify Available Network Interfaces

       Detect the network interface that you desire to implement the packet loss initially. For this step, you can point down all accessible network interfaces through:

       ip link show

Step 2: Include Packet Loss Rule

       The term eth0 is considered as the network interface that you desire to simulate packet loss and it can be the name of your real network interface. Apply the specified command when you intend to simulate a 1% packet loss rate:

       sudo tc qdisc add dev eth0 root netem loss 1%

       To employ netem by presenting a 1% packet loss, the mentioned command configures the root queue discipline (qdisc) on eth0.

Step 3: Check Configuration

       You can list the lively qdisc setups for your interface to assure that your packet loss rule has been implemented:

       sudo tc qdisc show dev eth0

Step 4: Experiment the Network

       Now, validate your network applications or protocols to view in what way they work under these criteria using the packet loss simulation which is active. Executing network benchmarks, streaming video and sending files can be included in this procedure. 

Step 5: Eliminate Packet Loss Rule

       Plan to delete the packet loss simulation after completing the process of experimenting. Through the command, you can remove the qdisc scenarios:

       sudo tc qdisc del dev eth0 root

       For breaking the packet loss simulation efficiently, this command eliminates the root qdisc.

Advanced Configuration

  • Variable Packet Loss: Utilize the correlation and random choices to simulate a very dynamic platform with variable packet loss rates.
  • Collaborating Effects: For highly extensive simulations, integrate packet loss with other network criteria such as replication, jitter and latency by making use of netem.
  • Specific Traffic: To implement any criteria or packet loss to particular kinds of traffic, you can utilize tc filters that are detected by protocols, IP addresses and port numbers.
