Abstract
In the recent years, there is a huge increase in the bandwidth requirements for the
backbone transmission networks, and this due to the wide use of packet and multimedia
services. Accordingly, industry focus has turned to realizing a vision of evolving the
Backbone Transmission Networks. Backbone Transmission can be evolved through
introducing two next generation transport networks supporting more scalability and
efficiency. One Layer will be responsible for the grooming functionalities through the
Optical Transport Networks (OTN), the other layer will be responsible for the aggregation
& Layer 2 Switching capabilities through the Packet Transport Networks (PTN).
Moreover, Due to the efficient use of high order wavelengths without wasting bandwidth
through using OTN grooming & PTN aggregation within the Backbone networks, the
migration of line speeds from 10 GB/s into 40 GB/s and 100 GB/s becomes necessary. On
the other hand, transport networks can be dimensioned as the interaction of two operating
planes, a transport plane and a management plane. Optical control planes sit between the
management and transport planes. The control plane moves some of the network
intelligence down to the network elements.
This thesis explains the main concepts of the two next generation Transport Networks,
Optical Transport Networks for the grooming of the aggregated services into high order
line rates (40 GB/s & 100 GB/s), then Packet Transport Networks as an aggregation layer
for multiple services with powerful IP switching functionalities. Also we are going to see
in this thesis the deployment of optical control planes that sit between the management and
transport planes.
