A new family of 2D wavelength/time codes with large cardinality for incoherent spectral amplitude coding OCDMA networks and analysis of its performance
Photonic Network Communications - Tập 19 - Trang 204-211 - 2009
A new family of two-dimensional wavelength/time codes (2D-W/T-MQC/MQCs) and its
system structure of encoder/decoder are proposed, which is based on tunable
optical fiber delay lines (TOFDLs) and fiber Bragg gratings (FBGs).
Multiple-access interference (MAI) can fully be eliminated by using a
wavelength/time balanced detector structure at the receivers. Furthermore, the
performance of the system i...
A New Analytical Model of Shared Backup Path Provisioning in GMPLS Networks
Photonic Network Communications - Tập 4 - Trang 271-283 - 2002
As GMPLS and its supporting set of protocols develop into aviable control plane
for optical networks, an important function that they will need to support will
be the protection and restoration function that has been a major feature of
legacy optical networks. A network with a robust set of protection and
restoration mechanisms will be able to support data traffic while allowing
faster recovery fr...
Macroscopic and microscopic techno-economic analyses highlighting aspects of 5G transport network deployments
Photonic Network Communications - Tập 40 Số 3 - Trang 256-268 - 2020
5G networks will comprise multiple, versatile infrastructures at finest
granularity consisting of multiple disaggregated pools of network, compute and
storage resources. To support the 5G network architectures and satisfy the
access network demanding performance requirements, transport networks consisting
of various converging technologies shall provide mechanisms to support
deployment flexibility...
Connection Management Protocols for Dynamic Lightpath Provisioning in Future WDM Networks
Photonic Network Communications - Tập 6 - Trang 25-32 - 2003
This paper investigates and compares the performance of two GMPLS-based
distributed control and management protocols for dynamic lightpath provisioning
in future IP networks. The first protocol is a global information-based link
state approach that consists of both an integrated RWA algorithm and a signaling
algorithm. Two triggering mechanisms for the LSAs update procedures are
considered; one is...
Inter-domain lightpath provisioning policy in support of hierarchical multi-target QoS
Photonic Network Communications - Tập 22 - Trang 51-58 - 2011
As the DWDM distributed multi-domain optical networks has been advocated to be
the next generation networks, there is a pressing need to propose a set of
effective light path provisioning policies. Meanwhile, with the growth of
service types, different types of service should be set in different priority
levels and pursuit individual QoS requirements. Thus, a new lightpath
provisioning policy in s...
Experimental demonstration of software-defined optical network for heterogeneous packet and optical networks

Comparison of p-cycles and p-trees in a unified mathematical framework
Photonic Network Communications - Tập 14 - Trang 123-133 - 2007
As high-speed networks grow in capacity, network protection becomes increasingly
important. Recently, following interest in p-cycle protection, the related
concept of p-trees has also been studied. In one line of work, a so-called
“hierarchical tree” approach is studied and compared to p-cycles on some points.
Some of the qualitative conclusions drawn, however, apply only to p-cycle
designs consis...
Scalability of Wavelength Division Multiplexed Optical Passive Star Networks with Range Limited Tunable Transceivers
Photonic Network Communications - - 1999
The number of stations attached to a single optical passive star is limited by
current state of the art in optical technology. Also, the wavelength range of
tunable optical transceivers is limited by current technology. Many high
performance computing applications require the use of large size regular
topologies for communication between computing nodes. Scalability of passive
star networks built ...
Simple Scheduling Algorithms for Use with a Waveguide Grating Multiplexer Based Local Optical Network
Photonic Network Communications - Tập 1 - Trang 35-48 - 1999
As the need for greater bandwidth in local-area networks grows,
wavelength-division multiplexing (WDM) is gathering attention as a viable
successor to Gigabit Ethernet technologies. In this paper we introduce a new WDM
optical LAN architecture based on the waveguide grating multiplexer (WGM) rather
than the traditional passive star coupler (PSC). An N-port WGM allows N 2 × N 2
connectivity via onl...
Design and Performance Evaluation of Traffic Grooming Algorithms in WDM Multi-Ring Networks
Photonic Network Communications - Tập 3 - Trang 335-348 - 2001
In this paper, we propose novel traffic grooming algorithms to reduce the cost
of the entire system in WDM multi-ring networks. In order to achieve this goal,
it is important to construct a virtual topology and groom the traffic in these
networks. We consider four kinds of virtual topologies of WDM multi-ring
networks according to the way in which traffic is transmitted among rings.
Accordingly, w...
