Abstract Performance control in packet switching networks is one of the remaining areas that are yet t o be explored. In this paper we look into the performance problems with two existing networ k architectures, datagram and virtual circuit. The major problem with the datagram network i s lack of effective traffic control; and with the virtual circuit network, the improperly define d network control semantics and mechanisms. We consider that a new network architectur e should be investigated in order to provide performance support for diverse applications. 1. Introductio n In packet switching computer communication networks, the network layer in the architectur e plays an important role. Its functionality is to deliver user data bits with specified performanc e requirements. Above it is the end-to-end transport layer residing in users ' hosts. It is th e network layer, together with the layers below it, that physically carries out data transmissions. Its performance determines how good the network transmission services will be. Traffic congestion has been a major obstacle in achieving good network performance. Dat a from all sources are statistically multiplexed on shared network resources; the moment-tomoment
