“…13: an SDN-enabled fast protection mechanism and end-to-end service restoration in case of a primary link failure [31], [32]; and an SDN-enabled dynamic wavelength allocation (DWA) in response to an increased traffic demand [30]. In the fast protection use case the service restoration time is measured at the ONU when a failure event is caused by a cut in the backhaul link between the primary OLT and the AN [33]. Silence in the upstream activates a countdown timer in the primary OLT controller, which on expiry generates a failure detection and an in-band alarm to the Openflow access NC.…”

Abstract-This paper reports on the architectural, protocol, physical layer and integrated testbed demonstrations carried out by the DISCUS FP7 consortium in the area of accessmetro network convergence. Our architecture modelling results show the vast potential for cost and power savings that node consolidation can bring. The architecture however also recognises the limitations of long-reach transmission for low latency 5G services, and proposes how to address such shortcomings in future projects. The testbed results, which have been conducted end-to-end, across access-metro and core, and have targeted all the layers of the network, from the application down to the physical layer, show the practical feasibility of the concepts proposed in the project.Index Terms-access metro, network convergence, fixed mobile convergence, long-reach PON, flat optical core, optical island, 5G architecture, next generation multi wavelength PON.

“…This is then passed to an Event Plane, implemented using the ZeroMQ libraries (as explained in [19]), which bypasses the slower Javascript object notation (JSON) interfaces. In this experiment we have used a proprietary interface for the I-CPI, although in [20] we have demonstrated the interoperability of our NC with the control orchestration protocol (COP) [21].…”

“…In addition we carried out some modifications to the XG-PON standard to adapt the protocol to the longer PON logical distance supported, up to 125km as opposed to 60km, and the higher split ratio supported, 512 versus 64. The reader can refer to [19] for more details on the OLT and ONU implementation.…”

“…In the case of a failure, the detection and restoration time shall be as low as possible. Table III summarizes the failure detection and restoration times for all the protection architectures and compares their values to the unprotected architecture [21], [22]. So the RP architecture is able to provide the lowest failure detection time, thus minimizing the delay due to the failure.…”

Abstract-Access networks are evolving fast by increasing their capacity and coverage area, coping with a larger number of users and variety of terminals. Operators aim at keeping high network performance and quality of service but limiting their capital and operational expenditures by e.g., minimizing investments and energy consumption using power saving at the network components. To address these challenges this paper evaluates energy consumption, connection availability and failure detection time of three protection schemes applicable for converged access networks: Disjoint Fiber Protection, Energy-Efficient Disjoint Fiber Protection, and Reflective Disjoint Fiber Protection. The schemes are assessed by a case study considering public Intelligent Transport System (ITS). The studied ITS deploys a Dedicated Short Range Communications (DSRC) Radio Access Network connected to the service server through a protected passive access network. Comparison with unprotected architecture shows that the Reflective Disjoint Fiber Protection offers low energy consumption and high connection availability, while it significantly reduces the failure detection time and hence, the connection interruption time.
