Next Generation Transmission

Product Description

Overview

The introduction of new services such as voice over IP, video on demand & IPTV is putting increased pressure on operators to provide more bandwidth in their existing core & access telecommunications networks. Bandwidth requirements for normal web browsing alone are currently increasing at 40% year on year. This creates problems for operators who face intense competition in a market with a decreasing value per bit; yet existing transmission infrastructure has a high cost per bit.

This detailed technical class describes how new technologies & techniques are being used to reduce Cap Ex & Op Ex by moving services away from traditional TDM-based to converged packetswitched networks.

After a brief review of current network solutions the class introduces layer 2 virtual circuit options in Frame Relay, ATM & MPLS. The class then moves on to Carrier-Based Ethernet solutions. Next there is a review of SDH followed by an explanation of the changes for Next Generation SDH. This is followed by a detailed treatment of Optical Transmission Networks (OTN) including the latest options for DWDM. The class concludes with coverage of the pseudo-wire options that help maintain legacy continuity in the transition to next generation networks.
