The total non-blocking throughput of a network switch refers to the maximum amount of data that can be transmitted simultaneously without any bottlenecks or congestion within the switch. It indicates the switch’s capacity to handle the aggregate traffic across all its ports.
In a non-blocking switch, the switching fabric (internal architecture) is designed in such a way that it can handle the maximum data rate for all ports concurrently, ensuring that there are no data collisions or delays. Essentially, it means that every port on the switch can transmit and receive data at full speed simultaneously without any performance degradation.
The total non-blocking throughput is typically expressed in terms of Gigabits per second (Gbps) or Terabits per second (Tbps). For example, a switch with a total non-blocking throughput of 48 Gbps means it can handle up to 48 Gigabits of data per second without any blocking or congestion.
It’s important to note that the total non-blocking throughput is a theoretical maximum and assumes ideal conditions. In practical scenarios, factors such as packet size, network congestion, and the type of traffic (unicast, multicast, or broadcast) can affect the actual achievable throughput. It’s advisable to consider real-world network requirements and consult the specifications provided by the switch manufacturer to determine the appropriate switch with adequate non-blocking throughput for your specific network needs.
