Abstract An open converged metro-access network approach allows for sharing optical layer resources like fibers and optical spectrum among different services and operators. We demonstrated experimentally the feasibility of such a concept by the simultaneous operation of multiple services showing different modulation formats and multiplexing techniques. Flexible access nodes are ...

  • Woltering M.
  • Wuebben D.

This paper discusses two approaches of adapting the size of Hybrid-ARQ (HARQ) retransmissions in a 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) uplink system. One goal of communication systems is to achieve a reliable transmission with a minimum utilization of the channel. In case of a decoding error ...

Field trial demonstration of open shared metro-access infrastructure

  • Bonk R.
  • Pfeiffer T.
  • Poehlmann W.
  • Schmuck H.

An open access network approach allows for sharing optical layer resources like fibers and optical spectrum among different services and operators at the same time. In a field trial the feasibility of such a concept has been demonstrated. Flexible access nodes are implemented including amplification and dispersion management to generate ...

5GNOW: Alcatel-Lucent Bell Labs Germany Concepts and Results Contribution for Future Network and Mobile Summit 2013

  • Chen Y.
  • Schaich F.
  • Ten Brink S.
  • Wild T.

The 5GNOW approach is able to efficiently support different traffic types, which all have to be part of future wireless cellular systems. Our vision of a unified frame structure concept aims at handling the large set of requirements within a single 5G system. A filtered multicarrier approach will enable the ...

Block-Filtered Multi-carrier Technique for Wireless Systems Beyond LTE

  • Frigon J.
  • Schaich F.
  • Ten Brink S.
  • Vakilian V.
  • Wild T.

In this paper, we propose a novel multi-carrier transmission scheme as an alternative approach to orthogonal frequency division multiplexing (OFDM) in order to mitigate intercarrier interference (ICI). In the proposed scheme called block-filtered multi-carrier (BFMC), a filtering operation applied to a group of consecutive subcarriers in order to reduce the ...

Energy Reduction Strategies in Elastic Optical Networks based on Traffic Aware Distributed GMPLS Control Plane

  • Morea A.
  • Verchere D.

The daily, weekly, and yearly traffic variations and traffic growth as well as energy efficiency strategies based on elastic optical networks, sleep mode and grooming strategies represent a good environment for achieving significant energy savings. We adapt the resources assigned for an optical channel by using a GMPLS distributed control ...

Power efficient service differentiation based on traffic-aware survivable elastic optical networks

  • Morea A.

This study assesses the feasibility of defining different service classes based on protection schemes in core optical networks. Moreover, we propose a dedicated energy saving strategy for each of the service classes in order to minimize the overall power consumption of the network. Four classes of service are proposed: platinum, ...

Impact of traffic fluctuations and dedicated protection on energy savings in dynamic elastic optical networks

  • Morea A.
  • Turus I.
  • Verchere D.

We present an analysis of the energy savings when taking into account a realistic traffic model. Daily and weekly traffic fluctuations as well as yearly traffic growth are taken into account when analyzing the power consumption given by the powered-on equipment as well as the IDLE opto-electronic devices. We also ...

Load-based Transparent Reach Maximization in Elastic Optical Networks

  • Alberto Bononi
  • Morea A.
  • Paolo Serena

We propose a novel power-selection strategy for maximizing the transparent reach in elastic optical networks based on knowledge of the average wavelength load, and we quantify the savings in regenerations with respect to using the full-load standard reach.

IoT360 Lecture on IoT Service Platforms

  • Roelands M.

Invited lecture at IoT360 Summer School, 31/10/2014, Rome, Italy, http://iot-360.eu/summer-school/summer-school-program/ Abstract: IoT Service platforms are not different from other (possibly distributed) stream-intensive service creation and execution environments, but the IoT perspective elicits generalisable requirements related to the observation & actuation interaction the platform has with the real world in which ...
