Cable Modem Flap
Cable modems can have a problem known in industry jargon as "flap" or "flapping". A modem flap is when the connection by the modem to the head-end has been dropped (gone offline) and then comes back online. The time offline or rate of flap is not typically recorded, only the incidence. While this is a common occurrence and usually unnoticed, if a modem's flap is extremely high, these disconnects can cause service to be disrupted. If there are usability problems due to flap the typical cause is a defective modem or very high amounts of traffic on the service provider's network (upstream utilization too high). Types of flap include reinsertions, hits and misses, and power adjustments.

Famous quotes containing the words cable and/or flap:
“To be where little cable cars climb halfway to the stars.”
—Douglass Cross (b. 1920)
“Let Sporus tremble—‘What? That thing of silk,
Sporus, that mere white curd of ass’s milk?
Satire or sense, alas, can Sporus feel,
Who breaks a butterfly upon a wheel?’
Yet let me flap this bug with gilded wings,
This painted child of dirt, that stinks and stings;
Whose buzz the witty and the fair annoys,
Yet wit ne’er tastes, and beauty ne’er enjoys:”
—Alexander Pope (1688–1744)
