The End to End Network Delay Time calculator computes the time for data transmitted through a network of routers.
INSTRUCTIONS: Choose units and enter the following:
- (n) Number of Links between Routers
- (dproc) Average processing delay incurred by a router
- (dtrans) Average transmission delay
- (dprop) Average propagation delay
End to End Delay Time (t): the calculator returns the time in milliseconds (ms). However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
End-to-end delay is the total time it takes for a packet to be sent through a network. Each router has its own separate delay time, so this only gives an estimation.
The End to End delay time equation is:
x = n * (dproc +dtrans + dprop)
where:
- x - End to End network delay time
- n - the number of links between routers
- dproc - the average processing delay incurred by a router
- dtrans - the average transmission delay
- dprop - the average propagation delay
Note: the number of links is equal to the number of routers minus 1.
- Propagation Delay - computes the delay between two routers based on their positions and a transfer rate.
