Ericsson and Telefónica have together successfully showcased a traffic-agnostic 5G-ready transport solution for both Radio and Fixed Enterprise Access. It is based on Ericsson’s groundbreaking and future-proof eXhaul concept, which allows a wide range of transport technologies, including CPRI, eCPRI and Ethernet, to efficiently and securely share the same physical infrastructure.
SDN was the main keyword when it came to optical networks and their control at the OFC 2015. Orchestrating resources across multiple layers and domains—as an important next step in introducing SDN to the networks—is specifically worth highlighting. In other words, multi-layer/multi-domain orchestration seems to have emerged as a major added value of SDN to the networks.
At the conference, we presented details behind our SDN-based multi-domain orchestration demonstrator as a Post-deadline paper.
