Bandwidth control in redundant news server links

Usenet news is a worldwide network of servers providing discussion forums with topics ranging from scientific research to hobbies, entertainment or politics. Redundant links between servers are used to provide fault tolerant operation of individual servers despite the possible network link failures. As the volume of news articles can take up to 200 gigabytes per day, this poses a problem of exhausting the bandwidth of some underlying network connections while other connections are not satisfactorily utilised. The paper shows this problem in more detail and proposes methods of controlling the direction of news data streams while preserving the redundant architecture of server connections
