GPON : Architecture and Protocols

Course Overview

GPON network offers greater interoperability with metro-core networks and it is specially designed to work with IP or ATM Protocol in the backhaul. In a connectionless environment such as IP cloud, traffic engineering is an important issue that addresses end-to-end service delivery and network efficiency. When a service provider deploys such a network in the access, it is very important for its Engineers to understand how protocols converge at different layers of the OSI especially at the time critical services like voice & video are offered in the Telco network.
