With the introduction of a Cloud Networking Service manager, reconfigurable wavelength switched optical network is suitable to deliver Infrastructure as Services to enterprises.
However some fundamental challenges still remains to be solved such the standard specifications of services scheduler architecture for Telecom Networks.

greater 100Gbps in capacity with equivalent reach will
not fit within the standard ITU 50GHz channel spectrum

Review: Core Networks Part III by F. Dikbiyik
• Low-bandwidth-connection routing and
multiplexing optimization in DWDM mesh
networks
• Incremental traffic model
• Physical layer constraints
• Cost = OT cost (term OT, regen OT) + common
cost (device cost, amp cost, etc. in per lambda-
channel -mile
1. Investment cost
2. Average cost
3. Weighted cost
4. Major – Minor Cost

Review: Core Networks Part III by F. Dikbiyik
Many IP over WDM approaches are
technically unrealistic, as they definitely
break the way that current IP networks are
hierarchically designed and operated

1. Minimize # of logical hops (minLH): i.e.,
minimize electronic processing of the
connection requests
2. Minimize # of physical hops (minPH): i.e.,
maximize wavelength utilization
3. Minimize # of new lightpaths (minNL):
i.e., minimize # of transmitters and receivers
4. Minimize # of physical hops on ligthpaths
carrying the request (minTH): i.e.,
maximize wavelength utilization

PERCEPTIONS
1. Internet is growing without bound
2. Internet is the only driver for large Optical-
Layer capacity
Page 35

Clarification of perception #2: Both IP services and
Private lines play a major role.

32% per year
Penetration rate of broadband services grew
by 31% per year from 2000 to 2009
Estimate of average traffic growth in USA
over the last decade is 70%
Page 38
OTuR1: Traffic Types and Growth in Backbone Networks
Review: Core Networks Part III by F. Dikbiyik
2 orders of magnitude over
the last 9 years
4 orders magnitude over
the last 12 years
We expect the traffic per subscriber to continue
to grow at 30% and therefore deceleration of
aggregate US traffic growth (projected 33% per
year in the US until 2014), is due to wireline
broadband market saturation

Percptions: Internet is growing without bound and
still constitutes a significant driver for Optical-
Layer capacity
Observations: Private line services still drive a
large portion of Optical-Layer capacity in US
carrier networks.
The growth of core IP services has significantly
leveled off compared to the past decade.
The key questions : how residential video content
and distribution will evolve and to what relative
size wireless data and video will continue to grow.
