Python in Networking: Transforming Telecom in Bangladesh

Python scripting helps automate telecom networks efficiently.

Introduction

Python has become the most popular programming language for network automation. In Bangladesh, telecom operators like Grameenphone, Robi, Banglalink, and Teletalk are adopting Python to automate thousands of routers and switches. This reduces manual work, minimizes errors, and speeds up deployments.

Why Python for Networking?

• Simplicity: Easy to learn and beginner-friendly.
• Libraries: Rich networking modules (Netmiko, Paramiko, NAPALM, etc.).
• Multi-Vendor Support: Works across Huawei, Juniper, Cisco, ZTE.
• Community: Large global + Bangladeshi support groups.

Automation with Python is transforming multi-vendor telecom infrastructure.

Popular Python Libraries in Telecom

• Netmiko: Simplifies SSH connections to routers/switches.
• NAPALM: Vendor-neutral library for configs and monitoring.
• Paramiko: Secure SSH automation.
• Requests: Useful for APIs (RESTCONF, NETCONF, vendor APIs).

Hands-On Example: Using Netmiko

Here’s a simple script to connect to a router and run the show ip interface brief command:

from netmiko import ConnectHandler

# Device info (example with Cisco router, change for Huawei/Juniper)
device = {
    "device_type": "cisco_ios",
    "host": "192.168.1.1",
    "username": "admin",
    "password": "password",
}

# Connect to device
net_connect = ConnectHandler(**device)

# Run command
output = net_connect.send_command("show ip interface brief")
print(output)

# Close connection
net_connect.disconnect()

👉 With just a few lines of Python, you can log into a router, run commands, and collect output automatically.

Engineers in Bangladesh are learning Python to manage routers and switches faster.

Conclusion

Python is no longer optional for telecom engineers — it’s a must-have skill. With 5G, IoT, and cloud-native networks expanding in Bangladesh, Python-powered automation will play a vital role. Students and professionals who adopt Python today will lead tomorrow’s telecom innovations.
