7.2 Final words

Hopefully, the ideas in this dissertation will serve as a useful foundation for the design and architecture of future networks, and they will encourage further research on the integration of circuit and packet switching. This approach will allow us to use all-optical switches that scale and can cope with the rapid growth of Internet traffic.
