News distribution methods
IP-Plus currently supports two type of Usenet article distribution methods, one
client-server based and another between peer-servers.
- The Client/Server method permits IP-Plus customers to access the Usenet by means
of their news reader software. Clients access the server news.ip-plus.net (port 119).
The various hierarchies as well as the articles are kept locally on the IP-Plus server and are
maintained by IP-Plus. They are dowloaded onto the customers' clients upon NNTP requests.
- The Feed between peers method is setup between the IP-Plus newsfeed server
(newsfeed-zh.ip-plus.net) and the customers' news servers. IP-Plus pushes new articles
to the peers as soon as they are received. The customers are responsible of keeping and
maintaining the hierarchies and the articles locally to their servers. The feed can be
either full (all articles are passed on) or limited to the wanted hierarchies specified by
the customer. Note that keeping a news server with a full feed can be very resource demanding,
as circa 50 to 60 GB of data are received daily as Usenet traffic (estimate figure valid at
March 2001).
Alternatively, customers can setup a sucking feed, i.e. instruct their servers to
access news.ip-plus.net and grab the news concerning the hierarchies they require. This
method is analog to the client/server method as far as IP-Plus is concerned and its
configuration is completely left on the customers' hands.
IP-Plus currently only supports feeds with customers and partners.
