Choosing A Window Size (N)
There are a few things to keep in mind when choosing a value for N.
1: The sender must not transmit too fast. N should be bounded by the receiver’s ability to process packets.
2: N must be smaller than the number of sequence numbers (if they are numbered from zero to N) to verify transmission in cases of any packet (any data or ACK packet) being dropped.
3: Given the bounds presented in (1) and (2), choose N to be the largest number possible.

Famous quotes containing the words choosing, window and/or size:
“Let him be great, and love shall follow him. Nothing is more deeply punished than the neglect of the affinities by which alone society should be formed, and the insane levity of choosing associates by others’ eyes.”
—Ralph Waldo Emerson (1803–1882)
“And though in tinsel chain and popcorn rope
My tree, a captive in your window bay,
Has lost its footing on my mountain slope
And lost the stars of heaven, may, oh, may
The symbol star it lifts against your ceiling
Help me accept its fate with Christmas feeling.”
—Robert Frost (1874–1963)
“For truly I tell you, if you have faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you.”
—Bible: New Testament, Matthew 17:20.
