Technological Evolution of a Telecommunications Operator’s Network


In the competitive world of telecommunications, network efficiency and reliability are crucial for customer satisfaction and operator success. This case study highlights how our engineering team spearheaded the technological evolution of a network for an operator with 3,000 customers, addressing critical issues and significantly improving network performance and flexibility.


Initial Challenges

The operator faced several challenges related to its Layer 2 network:

  • Network Loops: The network suffered from frequent loops, causing service interruptions.
  • Manual Backup Links: Switching to backup links had to be done manually, requiring physical presence at data centers to restore traffic.
  • Outdated Firewall Rules: The firewall rules were outdated, leading to anomalous behaviors and security issues within the network.


Implemented Solutions

Our team carried out a series of technical improvements to resolve these issues:

  • Migration to Layer 3: The network was configured and migrated from Layer 2 to Layer 3, eliminating loop issues and improving overall stability.
  • Traffic Balancing: We implemented traffic balancing techniques, allowing the use of asymmetric flows and optimizing the utilization of network resources.
  • Dynamic Backup Links: The network was configured to automatically switch to backup links in case of failure, ensuring minimal service interruption for end customers.
  • Firewall Rules Update: All firewall rules were reviewed and updated to align with best security and operational practices, eliminating anomalous behaviors.
  • Equipment Upgrade: Old equipment was replaced with more modern and robust devices, offering greater stability and better support for the applied solution.
  • Customer Concentration: Various customer access technologies were concentrated into two main cores, improving efficiency in IP addressing and optimizing resource aggregation.



The technological evolution of the network resulted in several key benefits:

  • Reduction of Interruptions: The elimination of loops and automatic switching of backup links significantly reduced service interruptions.
  • Improved Efficiency: Traffic balancing allowed for better utilization of network resources, enhancing operational efficiency.
  • Enhanced Security: Updating the firewall rules improved security and reduced anomalous behaviors within the network.
  • Improved Stability and Robustness: New equipment increased network stability, better accommodating dynamic demands and changes.
  • Efficiency in IP Addressing: The concentration of access technologies into two cores significantly improved IP address management.
  • Customer Satisfaction: The operator’s 3,000 customers experienced a more reliable and continuous service, enhancing their overall satisfaction.
