THROUGHPUT V S BANDWIDTH FULL

However, network throughput depends on the access method (for example, token passing or carrier sensing), the load on the network, and the error rate.įigure 2-1 shows the ideal situation, where throughput increases linearly with the offered load, and the real world, where actual throughput tapers off as the offered load reaches a certain maximum.įigure 2-1.

(Offered load is the data that all nodes have to send at a particular moment in time.) Theoretically, throughput should increase as offered load increases, up to a maximum of the full capacity of the network. The capacity of a network should be adequate to handle the offered load, even when there are peaks in network traffic. Capacity depends on the physical layer technologies in use. However, this is not the case on real networks. Ideally, throughput should be the same as capacity. You measure throughput, which can vary depending on network performance characteristics and how you make the measurement. Throughput is an assessment of the amount of data that can be transmitted per unit of time. Remember, bandwidth means capacity and is generally fixed. Network novices consistently misuse the words throughput and bandwidth. Throughput is often defined for a specific connection or session, but in some cases the total throughput of a network is specified. Throughput is defined as the quantity of error-free data that is transmitted per unit of time.
