To determine the switching capacity required for a switch with 10 ports at 1Gbps to be considered non-blocking, it is essential to understand the term "non-blocking." A non-blocking switch allows any port to communicate with any other port at the maximum supported speed without interference or data bottlenecks.

In the scenario where there are 10 ports, if each port can transfer data at speeds up to 1Gbps, the total bandwidth requirements would lead to a calculation of the maximum achievable throughput across the switch. When considering all ports possibly communicating simultaneously—each producing data at 1Gbps—the calculation would be as follows:

  • Each port (10 ports) can support 1Gbps.

  • Therefore, the theoretical maximum switching capacity required to prevent any blocking when all ports are in use is calculated by multiplying the number of ports by the speed of each port:

10 ports x 1 Gbps/port = 10 Gbps.

However, to maintain effective communication without blocking as network traffic increases and to account for variation in data paths, a typically accepted practice is to ensure that input and output paths are sufficiently larger than this theoretical maximum, enhancing performance and capacity. This leads to the need for consideration of
