Abstract:

The feature and performance of the representative optical network architectures were reviewed,and a novel PIONEER architecture that combines their advantages was proposed.Finally,programmable,scalable and upgradable software defined optical network(SDON)architectures were proposed for future optical networks.

Key words: automatic switched optical network, path computation element, software defined optical network, heterogeneous network inter-connection
