Carriers Face Many Challenges Integrating Their Currently Disparate Networks, Traffic Types and Services into a Common Packet-Based Core Network - 2006 Telecoms Infrastructure Technology

Posted on: Tuesday, 26 September 2006, 09:00 CDT

Research and Markets (http://www.researchandmarkets.com/reports/c42621)

has announced the addition of 2006 Telecoms Infrastructure Technology -

Volume 2 - Long Distance & Data to their offering.

The research begins with a detailed description of long distance optical

fibre technologies, including submarine cables with optical

amplification supporting dozens or hundreds of wavelengths with

Wavelength Division Multiplexing (WDM). A number of subtle physical

processes, including chromatic and polarization mode dispersion,

four-wave mixing and self-phase modulation set the upper limits for the

data carrying capacity of any fibre system. The author discusses these

and the techniques of Erbium Doped Fibre Amplification and Raman

Amplification, to provide detailed insight into the current state of the

art for long distance fibre communications. Satellite and microwave long

distance links are also discussed.

The report then considers traditional and advanced methods of modulating

data, including G.709 Optical Transport Network, which uses Forward

Error Correction to reliably carry SDH/SONET and packetised data over

fibre links in conditions of low signal-to-noise ratio. This important

development greatly enhances capacity and robustness of WDM systems. The

author discusses the established, highly reliable, SDH/SONET ring

architecture which is the basis of most carrier backbone networks today,

and the use of new technologies, including Resilient Packet Rings,

optical switching and Generalised Multiprotocol Label Switching (GMPLS)

to build flexible, redundant, long distance networks.

The author discusses the various Ethernet physical technologies,

including 10 and 40 Gigabit per second fibre, and the way Ethernet

framing and transport of data is increasingly preferred over SDH/SONET

and the older techniques of Frame Relay and ATM (Asynchronous Transport

Mode).

This report provides an extensive introduction to Quality of Service

(QoS) and Multiprotocol Label Switching (MPLS) techniques, which are

essential for the reliable delivery of voice, data and video services

using Ethernet and TCP/IP packet technologies. Carriers face many

challenges integrating their currently disparate networks, traffic types

and services into a common packet-based core network. The report

provides vital insight into the challenges of providing full end-to-end

QoS reservation of bandwidth and assurance of packet delivery over both

core and edge (last-mile) networks.

The author also discusses conventional ISDN SS7-based telephone

networks, PABXs (Private Automatic Branch Exchanges) and PC software

implementations of PABX functionality, including the open-source

Asterisk project.

While this report does not assume an engineer's

depth of prior technical knowledge, it provides a solid overview of

telecommunications core networks, data carriage and switching techniques

to enable the non-specialist to understand the technology in ways he or

she can apply to their own situation.

The companion volume to this report is available and provides an

independent introduction to Last Mile broadband technologies: 2006

Telecoms Infrastructure Technology - Volume 1 - Last Mile.

This report is an independent introduction, for managers, investors and

technical specialists, to long distance telecommunications technologies

and to the switching and carriage technologies for voice and data

communications.
