Data Delivery Time
The goodput is a ratio between delivered amount of information, and the total delivery time. This delivery time includes:
- inter-packet time gaps caused by packet generation processing time (a source that does not use the full network capacity), or by protocol timing (for example collision avoidance)
- data and overhead transmission delay (amount of data divided by bit rate)
- propagation delay (distance divided by wave propagation speed),
- packet queuing delay
- intermediate node store-and-forward processing delay,
- packet retransmission time (in case of deleted packets in congested routers, or detected bit errors),
- delayed acknowledge due to flow control, congestion avoidance and processing delay.

Famous quotes containing the words data, delivery and/or time:
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“There was no speculation so promising, or at the same time so praisworthy, as the United Metropolitan Improved Hot Muffin and Crumpet Baking and Punctual Delivery Company.”
—Charles Dickens (1812–1870)
“A house means a family house, a place specially meant for putting children and men in so as to restrict their waywardness and distract them from the longing for adventure and escape they’ve had since time began.”
—Marguerite Duras (b. 1914)
