Switching Capacity (Gbps):

Switching capacity is a critical specification for network switches, defining the maximum amount of data the switch can process at once. It determines the efficiency and performance of data transfer within a network infrastructure.

## Formula

The switching capacity (SCSCSC) of a network switch is calculated using the formula:

SC=PS×PCSC = PS \times PCSC=PS×PC

where:

• SCSCSC is the switching capacity (Gbps)
• PSPSPS is the port speed (Gbps)
• PCPCPC is the number of ports

## How to Use

To use the Switching Capacity Calculator:

1. Enter the port speed in gigabits per second (Gbps).
2. Enter the number of ports in the network switch.
3. Click the “Calculate” button.
4. The switching capacity will be displayed in gigabits per second (Gbps).

## Example

Consider a network switch with each port operating at 10 Gbps and having 24 ports. Using the calculator:

1. Enter 10 in the port speed field.
2. Enter 24 in the port count field.
3. Click “Calculate.”
4. The switching capacity is calculated as 240 Gbps.
