When a connection passes through two communication networks that guarantee quality of service in different ways, an active packet is sent from one network to the other. Quality of service in the one network is mapped to quality of service in the other network by execution of a program included in the active packet, at the entry node of the other network. End-to-end quality of service is thereby guaranteed, unnecessary exchanges of quality-of-service information are avoided, and each network can modify its quality-of-service practices at its own convenience.
