Abstract
-
This thesis proposes and devises a simple and cost effective packet-based broadband access solution for next-generation access networks that is scalable, reliable, and capable of delivering to end-users emerging triple play services over a single converged access network. Specifically, this work examines the technological requirements and assesses the performance analysis and feasibility for implementing a novel self healing ring-based local access PON architecture that addresses the limitations of current tree-based PON architectures including supporting private networking capability as well as providing a simple and cost-effective fully distributed resilience capabilities against any and all types of networking failures.;The main characteristic of the proposed architecture is that it supports a fully distributed control plane among ONUs for ONU-ONU communication (private networking capability). The control plane supports fully distributed fault detection and recovery mechanisms as well as a decentralized DBA scheme in which the OLT is excluded from both arbitration and fault detection/recovery processes.;We show that the proposed distributed solutions can overcome the problems associated with current centralized ones, and in the process prove that these distributed networking architectures and the associated fault detection and recovery schemes as well as bandwidth allocation algorithms and protocols have characteristics that make them far better suited for supporting cost effective resilience capabilities and for provisioning QoS schemes necessary for properly handling data, voice, video, and other real-time streaming advanced multimedia services over a single line. The objective of the proposed distributed solutions is to enhance the Ethernet's capabilities to ensure that real-time voice and IP video services can be delivered reliably over a single platform with the same QoS and ease of management as ATM or SONET.;Supported by the distributed architecture, this work develops several decentralized QoS-based DBA algorithms in which the OLT is excluded from the arbitration process. The proposed distributed architecture guarantees the delivery of delay and jitter-sensitive real-time services through the integration of both scheduling mechanisms at the ONU (inter and intra-ONU scheduling). The introduction of this integration feature can only be supported by a distributed architecture.;The proposed decentralized fault and protection schemes are capable of protecting against both node and distribution/trunk fiber failures. These schemes enable the restoration of all network traffic including upstream, downstream, and LAN data. In addition, these schemes can also protect against any combination of concurrent double failures including trunk/distribution fiber breaks and node failures. Furthermore, the recovery time associated with any and all different distribution network/trunk failures is still within the delay-bound limit required for delivering guaranteed triple play services.
