Abstract
In an apparatus in a computer network, message filtering proceeds by generating respective class specifiers from a received message, using the message source field, message destination field, and type of message field. The class specifiers are used for generating a class specification, and a domain class is generated from the class specification. A domain list is generated to provide a list of ports to which a message directed to the domain class is to be forwarded. The message is forwarded to the ports listed in the domain list. The apparatus may be a bridge, router, etc.
