Purpose of the issue:

In recent years the amount of traffic due to Internet-based services has 
become more and more evident. Besides the traditional services carried
by 
the Internet, essentially with no guaranteed quality-of-service (QoS), a 
migration to a number of real-time services over IP (Internet Protocol)
is 
foreseen in the near future.  This means that future network 
infrastructures will have to handle a huge amount of IP data traffic, 
including a significant amount of real-time traffic with demands for 
assured QoS.  However, a dilemma emerges for carriers and network 
operators: the cost to upgrade the infrastructure to support real-time 
IP-based traffic is unlikely to be supported by revenues.  One solution
is 
to make more effective use of bandwidth or, in a broader sense, of
network 
resources.  Traffic engineering (TE) is such a solution.  As stated in 
IETF-RFC 2702, TE aims at facilitating efficient and reliable network 
operations optimising network resource utilization and traffic
performance.

As regards transport technology, it is widely recognized that WDM
optical 
networks will play a significant role in the realization of the next 
generation transport infrastructure, which will have to support both 
traditional and Internet-based services.  These facts emphasize the need 
for challenging solutions for the architecture of future networks and
for 
network technologies that will enable the realization of new generation 
networks.  The characteristics of IP-based traffic require that the
network 
infrastructure utilize its resources in a more flexible and dynamic 
way.  So, a key issue for new generation optical backbone networks is
the 
achievement of TE strategies that support a range of different types of 
traffic with dynamic demands.

Specifically, TE means the ability of the network to dynamically control 
traffic flows, to optimise the availability of resources, to choose
routes 
for traffic flows while taking into account traffic loads and network 
state, and to move traffic flows towards less congested paths.


TE in optical networks means the way routing of lightpaths is achieved,
the 
way data flows coming from either a circuit or a packet bearer network 
layer, are groomed and routed onto the lightpaths.
A relevant network paradigm investigated worldwide is based on 
Multi-Protocol-Label-Switching (MPLS) technique and its generalization, 
namely GMPLS.  Several network architectures and deployment scenarios
have 
been proposed in the literature.  Constraint based routing algorithms
are 
also a key ingredient for realizing TE strategies.

This special issue of IEEE Network will seek to highlight active areas
of 
current research in, and the future of, new generation optical networks 
that will concretely apply TE concepts.

The aim of this special issue is to gather tutorial and survey papers on 
work related to:

* New generation optical network architectures and protocols
* GMPLS network architectures
* Routing and wavelength assignment (RWA) in new generation optical
networks
* Extension of IP routing concepts and algorithms in optical networks
* Control plane architectures for next generation optical networks
* Protection and restoration strategies and algorithms in new generation 
optical networks
* Traffic grooming in new generation optical networks
* Inter-working between the control and management planes in new
generation 
optical networks
* Routing algorithms in multi-layer networks
* Dynamic routing strategies and algorithms
* Coordination between the protection mechanisms at different network
layers
* Granularity issues for protection and restoration in new generation 
networks (protect the wavelengths or the data flows inside the
wavelengths? 
How to segregate the traffic?)
* Signalling required for TE

Manuscript Submission

We requests that all papers be submitted electronically as pdf or word 
files.  To submit a paper for consideration, authors should send the 
following information to the guest editors via email:
1. Title, Abstract of the paper and list of authors.
2. Indicate which author is to serve as the primary correspondence
contact.
3. Please list affiliation, mailing address, phone/fax numbers, and
email 
address of the correspondence author.

The correspondence author will then be provided with instructions to
upload 
the paper to a website.

Articles should be tutorial in nature and should be written in a style 
comprehensible to readers outside the specialty of the 
article.  Mathematical expressions/equations should be minimized. 
Articles 
should not exceed 4500 words.  Figures and tables should be limited to a 
combined total of six.  If the article exceeds these recommended limits, 
contact the Guest Editors.  References should be included to guide a
reader 
to more information on the topic; the reference list need not include
every 
available source  (a limit of 10 references is recommended).

Additional information including the complete "Guidelines for authors"
is
