What is the difference between the two mentioned networking parameters?
Can't we calculate one of them to get the other?
Dear Islam,
I think throughput the amount of data. There is not a correlation between End-to-End throughput and End-to-End delay.
Regards Christian
I think that some of differences are:
- E2E delay is represented in miliseconds (or seconds) and throughput is represented in bits per seconds (bps).
- Throughput is defined as number of bits that can be transfered over communication channel in unit of time and depend on numerous factors similar to factors that E2E depends, see below.
- E2E delay depends on physical medium and associated propagation time (there is difference in using optics, twisted pairs, radio, etc.) and intermediate devices such as routers switches etc.
End to End Delay is the summation of Transmitting Delay(at MAC layer), Propagation Delay and queuing Time of a packet.
Throughput is the number of packets successfully reached at destination per unit time.
E2E delay, which can also be Latency = processing time + queuing time + transmission time + propagation time.
Throughput is a measure of how fast we can actually send data through a network.
End to end delay is the sum of time taken from the source to the destination for a packet to reach. Throughput is the ratio of packets received by the destination to the packets sent by the source
End to end delay is the time taken by a packet to travel from source to destination. Delay depends on number of hops and congestion on the network. While through put is the rate of traffic received at the destination node e.g. packets/sec. Excessive delays can effect throughput. Higher delays could result in discarding the packets by routers due to breaching the limit of TTL, then ICMP packets are sent to the source and hence results in re-transmissions. Re-transmissions do not increase the throughput.
Overall delay obtained by a packet can be presented as a sum of the following:time delay obtained on the upper network layers (above MAC)+MAC layer time delay. On the other hand, the throughput is rate of information transfer. It is measured in bytes/bits per second.
End to End Delay is the time taken for a packet to be transmitted across a network from source to destination.
End to End Throughput is the amount of data sent or received on either of the end bits/second
The lenghts of lines might be issue too in bigger networks. Ultra-low delay paths are usually constructed by MinLenght rule applied on fibres, i.e. with maximal exclusion of any nodes along the way, Retransmissions decrease throughput from point of view of total time needed on transmission of the whole information.
