News article caching
The Intel NetStructure Cache Appliance can function as a news server or a caching news server. News, also known as USENET and discussions, is a system of online discussion groups. NNTP is the protocol used to retrieve and distribute these discussion groups. The appliance supports NNTP as specified in RFC 977 and many common and proposed extensions.
To read news articles, users need a news reader, such as Netscape Communicator or Microsoft Internet Explorer, and access to a news server. The appliance is a caching news server. It can be configured to sit transparently between users and a parent or backing news server, increasing responsiveness for the user and decreasing network bandwidth use and the load on the parent news server.
