Advances in open signaling and control, active networks, mobility management, transportable software, Web-based services access, and distributed systems technologies are driving a reexamination of existing network software architectures and the evolution of control and management systems away from traditional constrained solutions.

The 4th IEEE Conference on Open Architectures and Network Programming invites participation in this international forum on open programmable networks.OPENARCH is sponsored by the IEEE Communications Society and will be co-located and organized in conjunction with INFOCOM.

The best papers from the conference will be published as a special issue of Computer Networks on Programmable Networks.
