Comparing CIR Internet Connection and Shared Internet Connection: How to Check the Difference


Choosing the right internet connection is crucial for businesses and individuals who rely on a stable and consistent online presence. Two common options are CIR (Committed Information Rate) internet and shared internet connections. This article aims to provide a detailed comparison between the two and offers practical examples of how to check the difference. By understanding their characteristics and conducting appropriate checks, users can make an informed decision based on their specific needs.

CIR Internet Connection:

A CIR internet connection, also known as a dedicated internet service, offers guaranteed bandwidth allocation and consistent speeds. It provides a specific amount of bandwidth that is exclusively dedicated to the user, ensuring reliable performance at all times.

Shared Internet Connection:

A shared internet connection, on the other hand, involves multiple users sharing the same bandwidth. The available bandwidth is divided among users, meaning that the speed and performance can vary depending on the number of users and their activities.

How to Check the Difference:
1. Bandwidth Testing:

- CIR Internet: Conduct a bandwidth test using online tools, such as Ookla Speedtest or Measure the upload and download speeds consistently throughout the day. A CIR internet connection should consistently deliver the expected speeds regardless of the time or network traffic.

- Shared Internet: Perform the same bandwidth test on a shared internet connection during different times of the day. Observe variations in upload and download speeds, especially during peak usage hours when more users are online.

2. Latency and Ping Testing:

- CIR Internet: Use tools like PingPlotter or command prompt utilities to measure latency and ping times. A CIR internet connection will typically display low and consistent latency/ping times, ensuring a smooth and responsive online experience.

- Shared Internet: Similar to the bandwidth test, check latency and ping times on a shared internet connection during different times of the day. Note any significant fluctuations, as shared connections may experience higher latency during peak usage periods.

3. Network Performance Monitoring:

- CIR Internet: Implement network monitoring tools like PRTG Network Monitor or SolarWinds to continuously monitor the performance of the internet connection. Analyze data related to bandwidth utilization, latency, packet loss, and uptime. A CIR internet connection should exhibit stable and consistent performance metrics.

- Shared Internet: Employ the same network monitoring tools on a shared internet connection to observe performance patterns. Identify any instances of bandwidth congestion, increased latency, or packet loss during times of high network usage.

4. Consult Service Provider Documentation:

- CIR Internet: Review the service level agreement (SLA) provided by the CIR internet service provider. The SLA should clearly outline the guaranteed bandwidth, uptime commitments, and performance expectations. Ensure that the actual performance aligns with the promised service levels.

- Shared Internet: While shared internet connections may not have an SLA specific to individual users, consult the service provider's terms and conditions. Pay attention to any clauses related to bandwidth allocation, network management, and fair usage policies.


Example 1: A business subscribes to a CIR internet connection with a guaranteed bandwidth of 100 Mbps. Throughout the day, regardless of peak usage times, the speed consistently measures around 95-100 Mbps in both upload and download tests.

Example 2: An office utilizes a shared internet connection during business hours. The bandwidth test shows varying results throughout the day, with download speeds ranging from 50 Mbps during off-peak hours to 20 Mbps during peak usage times.


Choosing between a CIR internet connection and a shared internet connection requires careful consideration of your specific needs and expectations. By conducting bandwidth tests, latency and ping tests, network performance monitoring, and reviewing service provider documentation, users can effectively check the difference between the two options. Understanding these distinctions empowers individuals and businesses to make informed decisions, ensuring a reliable and consistent internet experience tailored to their requirements.
