Re-Provisioning of Advance Reservation Applications in Elastic Optical Networks

IEEE Access, 2017
Driven by the development of cloud computing and mobile Internet, network-based applications have become diverse. Besides the usual immediate reservation (IR) applications, which need to be served immediately, advance reservation (AR) applications have ...

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

Advanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

Using static connections to improve elastic optical networks performance

, 2017
Network resources are poorly used in Elastic Optical Networks under dynamic traffic conditions. A hybrid scheme where some resources are statically allocated and the remaining ones are devoted to dynamic traffic, is proposed and evaluated.Peer ...

Automatic Hidden Elastic Optical Bypasses in Multi-Layer Networks

Applied Sciences
This paper focuses on handling traffic demands dynamically in a multi-layer IP-over-elastic optical network (IP-over-EON). We propose a mechanism that uses two types of optical resources.

Performance Analysis of Automatic Hidden Ligthpaths in Multi-Layer Networks

Photonics, 2023
The problem of resource provisioning in multi-layer networks is an important issue. We discuss and analyze resource provisioning in terms of the visibility of optical resources for the virtual layer in a network.

Network coding-based protection scheme for Elastic Optical Networks [PDF]

2014 10th International Conference on the Design of Reliable Communication Networks (DRCN), 2014
Optical technologies are the foundations supporting the current telecommunication network backbones due to the high speed transmissions achieved in fiber optical networks. Traditional optical networks consist of a fixed 50 GHz grid, resulting in a low optical spectrum (OS) utilization, specifically with transmission rates above 100 Gbps.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, EarlyView.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.
