Peer exchange or PeX is a communications protocol that augments the BitTorrent file sharing protocol. It allows a group of users (or peers) that are collaborating to share a given file to do so more swiftly and efficiently.
In the original design of the BitTorrent file sharing protocol, peers (users) in a file sharing group (known as a "swarm") relied upon a central computer server called a tracker to find each other and to maintain the swarm. PEX greatly reduces the reliance of peers on a tracker by allowing each peer to directly update others in the swarm as to which peers are currently in the swarm. By reducing dependency on a centralized tracker, PEX increases the speed, efficiency, and robustness of the BitTorrent protocol.

Famous quotes containing the words peer and/or exchange:
“All nature is a temple where the alive
Pillars breathe often a tremor of mixed words;
Man wanders in a forest of accords
That peer familiarly from each ogive.”
—Allen Tate (1899–1979)
“I can exchange opinion with any neighbouring mind,
I have as healthy flesh and blood as any rhymer’s had,
But O! my Heart could bear no more when the upland caught the wind;
I ran, I ran, from my love’s side because my Heart went mad.”
—William Butler Yeats (1865–1939)
