Abstract
Currently, many large-scale, resource-intensive applications and services such as Grids supported only by high-performance, highly distributed infrastructures are being developed. These ultra-broadband services have put forward high requirements of end-to-end Quality of Service (QoS) and of dynamic resource management, which makes end-to-end optical resource provisioning necessary. For this reason an intelligent optical access network which combines advantages of Generalized Multi-Protocol Label Switching (GMPLS) and Passive Optical Network (PON) proposed here. In our scheme, GMPLS is in charge of providing control plane to manipulate PON communication and introduce traffic engineering, while PON technology such as WDM-PON is employed as data plane following the control of GMPLS. We describe the architecture of proposed network and illustrate the concept of common GMPLS control plane shared by both core and access network. Then the functional module of intelligent Optical Line Terminal (OLT) and Optical Network Unit (ONU) has been discussed. Finally, QoS model for access network and entire scheme for end-to-end optical service provisioning have been introduced in detail.
