Why not add service-name to port-number mapping to the information stored in domain nameserver databases? For example, if we decide to implement the Whizbang protocol on port 1234, then our nameserver would contain a resource record of the form Whizbang.SAIL.Stanford.EDU IN TCP-PORT 1234 Applications would refer to the protocol by name, and find the port number using a domain resolver, which will cache the information for next time. The "well-known" protocols would bypass this mechanism since their port numbers are known. Joe
