Hybrid resource reservation scheme for transparent integration of access and core optical transport networks

In this paper, we present a novel traffic control and distributed multiplexing scheme based on a hybrid long-reach fiber access network architecture. The proposed network architecture exploits very low cost end-user ONUs and achieves energy efficiency, reduced complexity and high-level scalability. The scheme allows a group of users to share an ultra-wide band long reach WDM-PON, in a fiber to the cabinet configuration, leading to core node consolidation and access-core integration. We show that this architecture can be exploited as a large scale distributed multiplexer that can be used to funnel traffic directly from access networks over a core optical network and describe a control plane architecture compatible with the concept of Software Defined Networking for simplifying the aggregation process and improving performance at the same time.
