“…PON multi-tenancy can be achieved by opening the network on different parts: physical optical distribution network (ODN), physical layer sharing (wavelength), active device sharing (VPON), and MAC layer sharing (frame level). In an open access scheme [20], [21], the ODN can be shared to multiple business partners (BPs) at different levels of the distribution network while providing the physical layer security.…”

Over the past decade, network operators worldwide have regarded passive optical networks (PONs) as a successful access network system and the preferred technology for fiber-to-thehome/building/curb/distribution-point (FTTx) architecture. However, implementing the state-of-the-art PONs requires a high initial capital expenditure (CapEx) to deploy fiber in the field and acquires the necessary active devices. Thus, new architectures need to be developed to share the physical architecture and enable the multi-tenancy capability in a flexible way to satisfy different requirements from the operators and users. This research proposes to integrate the next-generation TWDM-PON with software-defined network (SDN) and the network function virtualization (NFV) to provide highly enhanced form of virtual unbundling of broadband access networks, enabling cost sharing and the dynamics of a competitive landscape. The simulation results show that the proposed architecture and mechanism can provide better performance in multi-tenancy condition, while guaranteeing the quality-of-service requirements in terms of the mean packet delay, jitter, throughput, and packet loss ratio.

“…However, while this architecture can provide a basis towards the design of future networks, it lacks flexibility in the Optical Distribution Network side, as every user signal needs to be sent to the main central office for further processing. Based on this idea, in [33] the architectural concepts were further developed to provide additional flexibility with the inclusion of Branching Nodes (BN) positioned in place of some of the remote nodes in the LR-PON architecture, providing wavelength routing and signal monitoring, in addition to optical amplification. This for example would allow the add/drop of optical signals close to the end point for local processing, when and where required, thus significantly reducing transmission distance to satisfy the requirements of those applications with strict latency constraints.…”

Future 5G services are characterised by unprecedented need for high rate, ubiquitous availability, ultra-low latency and high reliability. The fragmented network view that is widespread in current networks will not stand the challenge posed by next generations of users. A new vision is required, and this paper provides an insight on how network convergence and application-centric approaches will play a leading role towards enabling the 5G vision. The paper, after expressing the view on the need for an end-to-end approach to network design, brings the reader into a journey on the expected 5G network requirements and outlines some of the work currently carried out by main standardisation bodies. It then proposes the use of the concept of network convergence for providing the overall architectural framework to bring together all the different technologies within a unifying and coherent network ecosystem. The novel interpretation of multi-dimensional convergence we introduce leads us to the exploration of aspects of node consolidation and converged network architectures, delving into details of opticalwireless integration and future convergence of optical data centre and access-metro networks. We then discuss how ownership models enabling network sharing will be instrumental in realising the 5G vision. The paper concludes with final remarks on the role SDN will play in 5G and on the need for new business models that reflect the application-centric view of the network. Finally, we provide some insight on growing research areas in 5G networking.
