Layered approach only provides benefits if

the cost ratio between packet and pure

TDM is very high.

100G output

Mixes of 1G, 2.5G, 10G, and 40G client signals in multiple formats can be

combined in arbitrary ways as long as the total bandwidth needed does not exceed

the wavelength capacity.

Non-OTN client circuits

of 1 Gb and higher rates

of in Ethernet, SONET /

SDH and other formats

are transparently

wrapped, groomed and,

mapped per the OTN

standard into higher

capacity wavelengths in

While each service provides situation is unique and our

calculations don’t necessarily apply to everyone. AT&T expects to

realize utilization improvements and economic value by deploying

OTN switches in its core backbone network and taking advantage

of flexibility that is provided.

NMC2: The Telstra Network and Transport Technology Evolution




Approaches towards 100 Gbps

1. Upgrading selected DWDM channels on an existing lower rate

system, e.g., a system originally designed for 10 Gbps DWDM.

2. Deploying a new DWDM system, designed to optimized for

100Gbps.

Telstra has deployed ultra-long haul 10 Gbit/s and 40 Gbit/s DWDM links in its

Australian network. Ultra-long haul network trials at 100 Gbit/s have been

undertaken. Future transport technology evolution considerations include OTN,

MPLS-TP, P-OTP and OBS technologies. OBS can offer network efficiency

gains of 22% or more.

The use of a parent PCE significantly

improves the network performance without

overloading the GMPLS control plane.
