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 correspondencecontact.
3. Please list affiliation, mailing address, phone/fax numbers, and email
address of the correspondence author.
