What is Extranet?

Extranet

Extranets are collaborative meta-networks which are set up between two or more Intranets to facilitate business or research communication. An example would be General Motors and the many subcontractors that supply GM with parts for their products. GM and it's partners establish links to tie each others Intranets together to better serve each others needs, such as secure communications for financial transactions, parts ordering, etc. Another example would be the Federal Reserve Bank, which maintains an Extranet connected to each of it's constituent banks for the transfer of funds.
