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.

• 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.

Review: Core Networks Part III by F. Dikbiyik

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.
