Abstract

A control mechanism for multi-domain optical networks with commercial optical transport network (OTN) equipment is demonstrated by using hierarchical software defined networking controllers. A solution based on extended OpenFlow is proposed to support the control virtual network interface in OTN networks. In this way, multi-vendor and multi-domain interoperability is achieved for transport networks, and bandwidth on demand (BoD) service is demonstrated in multi-vendor multi-domain OTN networks. Moreover, based on this hierarchical control architecture, BoD service is conducted in the field trial, which verifies the feasibility to introduce new services in the transport network.
