Automatic filtering of routing information in a data transmission system

摘要

This invention relates to a method for transmitting routing information in a data network having a unidirectional network link, a data transmission system and routers connected to a unidirectional network link. A data transmission system according to the invention comprises a first router (feed) (1) having a network interface (4a) for sending data packets and routing information to a unidirectional network link (10), and a second router (receiver) (2) having a network interface (4b) for receiving data and routing information from the unidirectional network link (10), wherein filtering means (7) for filtering routing information are provided to reduce the network traffic.
