Segment Routing in multi-layer networks

P. Castoldi; A. Giorgetti; A. Sgambelluri; F. Paolucci; F. Cugini

Segment Routing (SR) has been recently introduced to enable efficient traffic engineering while simplifying control plane operations. Thanks to the source routing paradigm, traffic flows can be dynamically routed along the network, effectively exploiting network resources. In this paper, dynamic SR operations for multi-layer networking are presented and experimentally demonstrated. In particular, SR-based dynamic optical bypass and effective load balancing are validated in a multi-layer network testbed, showing enhanced capabilities to achieve effective resource utilization while guaranteeing lightweight control operations.
