In the rapidly changing landscape of telecommunications, staying ahead calls for more than just having the latest technology; it also demands the skill to leverage it successfully. At Speedflow, we are committed to sharing valuable knowledge and insights to help our partners navigate these challenges successfully. Today, we would like to discuss our experience with the CPS (Calls Per Second) functionality in optimizing telecom traffic management.
The industry expert at Speedflow Communication Ltd
As business traffic continues to surge, with its unique challenges, CPS has become an essential tool for maintaining performance and profitability. To guide us through this topic, we turn to an expert in the field—Max Goshtynar, our Head of Voice Department at Speedflow Communication Ltd. With over 15 years of experience in the VoIP industry, Max has been at the forefront of implementing innovative solutions that enhance network efficiency and drive business growth. His deep understanding of telecom infrastructure and strategic approach to traffic management make him the ideal person to shed light on the importance of CPS and how it can benefit your business.
Max, can you explain how CPS works and how it helps in managing the number of new calls initiated per second?
Calls Per Second, or CPS for short, is a critical telecom metric that quantifies how many new calls a system can answer or initiate in a given second. Implementing CPS ensures a smooth and controlled call flow, preventing sudden spikes in traffic that could overwhelm the system.
What challenges did the industry face before implementing CPS, and how has this new functionality addressed those issues?
For the past 5 years, the industry has evolved to become more advanced and competitive, with a strong focus on providing superior service. Today, much of the traffic is business-related, often with a low Average Call Duration (ACD) and the potential for high volume spikes. These surges require modern, expensive servers that not every business can afford. Instead of investing in costly infrastructure, companies can effectively manage traffic by utilizing CPS (Calls Per Second) functionality to achieve targeted results.
What were the limitations of the existing methods for managing call capacity, and why was there a need to introduce CPS?
Before CPS, systems managed traffic by limiting the number of available ports. During high-traffic periods, this often led to system overloads, causing valuable, revenue-generating calls to be lost. CPS was introduced to prevent this, ensuring that only productive calls use capacity, thereby increasing and protecting revenue.
How is the CPS functionality going to impact profitability compared to traditional call control methods?
Allow me to provide an example from Speedflow’s experience. We successfully managed business traffic to Italy, consistently maintaining an impressive 40% ASR on an hourly basis. Unfortunately, despite our best efforts, we experienced a significant drop in ASR during peak hours (4-5 hours) due to a sudden increase in traffic from multiple clients. This resulted in our margin dropping to zero. Thanks to the successful implementation of the CPS feature, we were able to stabilize the ASR, leading to a significant recovery in our margin.
What measures does CPS take to prevent network congestion and ensure smoother traffic flow?
How does this contribute to overall system stability?
The management of call flow in CPS is achieved through the implementation of two algorithms: Tail Drop and Random Early Detection (RED). Tail Drop sets a limit on the maximum number of calls per second, while RED intelligently adapts the volume to avoid overwhelming the system. In other words, it “learns” and adjusts to maintain optimal performance.
The algorithms ensure the stability of the system and prevent congestion.
How can CPS settings be customized at the company level and for specific termination points?
Flexibility is a crucial skill in today’s market, and at Speedflow, we understand that. That’s why we have implemented CPS in MediaCore to address this need. Our system allows for the setting of multiple CPS limits per company, enabling it to quickly and efficiently respond to changes in traffic and maintain optimum efficiency at all times.
How can companies have higher profitability using CPS?
From my perspective, there are two primary options for effectively managing the increasing volume of calls: making a significant investment in expanding your server capacity or improving the efficiency of your existing servers. By optimizing the efficiency of your existing infrastructure, you can reduce equipment expenses and ultimately increase your revenue.
Final thoughts
The implementation of CPS functionality in telecom systems represents a significant advancement in how businesses manage and optimize their call traffic. As demonstrated by our in-house experience, CPS not only stabilizes network performance during peak hours but also enhances profitability by preventing system overloads and improving overall efficiency. With the insights shared by Max Goshtynar, Head of the Voice Department at Speedflow Communication Ltd, it’s clear that leveraging CPS is not just a technical upgrade but a strategic move that can drive substantial business growth.
The teams at MediaCore are formed by highly qualified professionals withhave the necessary skills and knowledge to clearly and successfully teach and provide information on how to use CPS functions.
As the VoIP industry continues to evolve, staying ahead with innovative solutions like CPS will be crucial for maintaining a competitive edge.
