committed burst size calculator

Introduction:

In networking, Committed Burst Size (CBS) is a parameter that specifies the maximum number of bits or bytes that can be transmitted by a network device within a given period of time. CBS is an important aspect of Quality of Service (QoS) mechanisms to ensure that high-priority traffic is not compromised by other traffic on the network.

To calculate the CBS value for a network device, one needs to consider various factors such as the device’s available bandwidth, the traffic rate, and the desired QoS objectives. In this article, we will explore how to calculate the committed burst size using different methods.

What is Committed Burst Size?

Committed Burst Size (CBS) is a parameter used in QoS mechanisms to limit the amount of traffic a network device can transmit within a specified period. CBS is defined as the maximum number of bits or bytes that can be transmitted by a device during a single transmission cycle. The CBS parameter is used to ensure that high-priority traffic receives the required level of service while preventing non-critical traffic from consuming excessive network resources.

How to Calculate Committed Burst Size?

There are various methods to calculate the Committed Burst Size for a network device, including:

Token Bucket Method

The Token Bucket method is one of the most common methods used to calculate the CBS value. This method involves using a token bucket algorithm to allocate tokens based on the network device’s available bandwidth and the desired QoS parameters. The tokens represent the amount of data that can be transmitted by the device during a single transmission cycle.

To calculate the CBS value using the Token Bucket method, one needs to determine the following parameters:

Token Rate: The rate at which tokens are added to the bucket

Bucket Size: The maximum number of tokens that can be stored in the bucket

Traffic Rate: The rate at which traffic is generated by the device

Once these parameters are determined, the CBS value can be calculated as follows:

CBS = Token Rate x (Bucket Size / (Token Rate – Traffic Rate))

Leaky Bucket Method

The Leaky Bucket method is another popular method used to calculate the CBS value. This method involves using a leaky bucket algorithm to limit the amount of data that can be transmitted by the device. The leaky bucket algorithm works by allowing data to be transmitted into the bucket at a fixed rate, but any excess data is discarded.

To calculate the CBS value using the Leaky Bucket method, one needs to determine the following parameters:

Bucket Depth: The maximum amount of data that can be stored in the bucket

Traffic Rate: The rate at which traffic is generated by the device

Bucket Rate: The maximum rate at which data can be transmitted from the bucket

Once these parameters are determined, the CBS value can be calculated as follows:

CBS = Bucket Depth + (Traffic Rate / Bucket Rate)

What is burst size in QoS?

Burst size in Quality of Service (QoS) refers to the maximum amount of data that a network device can transmit or receive over a short period. It is the peak capacity of a network device to handle a sudden increase in network traffic. Burst size plays a critical role in ensuring that high-priority traffic is not compromised by other traffic on the network.

How do you calculate CBS from Cir?

The Committed Information Rate (CIR) is another QoS parameter that specifies the average rate at which traffic is generated by a network device. To calculate CBS from CIR, one needs to use the Token Bucket method. The CBS value can be calculated as follows: CBS = CIR x Tc, where Tc is the length of the token bucket interval.
