The emergence of new interactive and peer-to-peer 2.0. This is a continuous process and new trends like the Internet of Things, Ambient Assisted Living, and Smart Senior are already emerging on the coming Web 3.0 horizon.As a consequence, all parts of the transport network (access, metro, backbone) have to support these applications, implying that much more bandwidth and new control schemes will be needed.The typical access bandwidth today is in the range of 384 kb/s to 2 Mb/s [10], which will need to be increased to 50 to 100 Mb/s to support broadband applications like

We propose to extend the scalability of Time Sensitive industrial Networks, by partitioning them into time/scheduling domains and interconnect domain-devices through an optical backbone acting asynchronously to them. We show drastic scalability improvements and a proof of concept.

In spite of its long term promise, all-optical switching is still plagued by high cost, low efficiency when handling bursty data traffic, immature management and protection and poor output port contention resolution leading to heavy loss. Given the current situation, hybrid approaches that keep the best features of optics, reverting to the electrical plane when expedient, constitute sensible interim steps that can offer cost-effective solutions along the road to an eventual all-optical core. Two such approaches developed in the framework of the European IP project NOBEL are presented in this work. The first is a quite mature solution that extends present day concepts to achieve multiplexing gain while keeping all the management and restoration benefits of SDH. The other mimics early LANs in executing a distributed switching via its electrical control plane using two-way reservations, thus restricting its applicability to smaller domains. Combining the two leads to a system fulfilling most of today's requirements for Tb/s core networks.
