Federated portal network (FPN) is a framework for remote content sharing between enterprise portals. In a federated portal network each portal can act as a producer, exposing the content to other portals or as a consumer, using the content shared by other producer portals.
A federated portal network is used, for example, in order to distribute applications according to different service-level agreements (SLA), maintain autonomous portals that are independent of the central corporate portal or allow subsidiaries to lower total cost of ownership (TCO) by sharing applications from one producer portal.
FPN has currently two modes of operation: remote delta links (RDL) and remote role assignment (RRA).
Famous quotes containing the words federated, portal and/or network:
“The Federated Republic of Europe—the United States of Europe—that is what must be. National autonomy no longer suffices. Economic evolution demands the abolition of national frontiers. If Europe is to remain split into national groups, then Imperialism will recommence its work. Only a Federated Republic of Europe can give peace to the world.”
—Leon Trotsky (1879–1940)
“Some sepulcher, remote, alone,
Against whose portal she hath thrown,
In childhood, many an idle stone—
Some tomb from out whose sounding door
She ne’er shall force an echo more,
Thrilling to think, poor child of sin!
It was the dead who groaned within.”
—Edgar Allan Poe (1809–1849)
“How have I been able to live so long outside Nature without identifying myself with it? Everything lives, moves, everything corresponds; the magnetic rays, emanating either from myself or from others, cross the limitless chain of created things unimpeded; it is a transparent network that covers the world, and its slender threads communicate themselves by degrees to the planets and stars. Captive now upon earth, I commune with the chorus of the stars who share in my joys and sorrows.”
—Gérard De Nerval (1808–1855)
