In telecommunication networks, traffic volume is a measure of the total work done by a resource or facility, normally over 24 hours, and is measured in units of erlang-hours. It is defined as the product of the average traffic intensity and the time period of the study.
- Traffic volume = Traffic intensity × time
A traffic volume of one erlang-hour can be caused by two circuits being occupied continuously for half an hour or by a circuit being half occupied (0.5 erlang) for a period of two hours. Telecommunication operators are vitally interested in traffic volume, as it directly dictates their revenue.
Famous quotes containing the words traffic and/or volume:
“Poems stirred
into paper coffee-cups, eaten
with petals on rye in the
sun—the cold shadows in back,
and the traffic grinding the
borders of spring ...”
—Denise Levertov (b. 1923)
“A tattered copy of Johnson’s large Dictionary was a great delight to me, on account of the specimens of English versifications which I found in the Introduction. I learned them as if they were so many poems. I used to keep this old volume close to my pillow; and I amused myself when I awoke in the morning by reciting its jingling contrasts of iambic and trochaic and dactylic metre, and thinking what a charming occupation it must be to “make up” verses.”
—Lucy Larcom (1824–1893)
