In this paper, we present ICN-FC, which is an Information-Centric Networking (ICN) based framework for efficient functional chaining (FC). The key enabling techniques for ICN-FC includes naming semantics, Interest & Data processing and an efficient FC forwarding strategy. By using the proposed solutions, a functional chaining request, which consists of the name of raw data and an ordered set of...
Extraction of features and subsequent classification of ground moving targets, especially humans and vehicles, are topics of great relevance for the theoretical research and practical application in the signal processing of the ground surveillance radar. Based on time-frequency (TF) spectrograms, a novel method for the feature extraction of micro-motion targets is proposed in this paper. The experimental...
In this paper, we review OpenFlow-based control and management technology for optical networks including multi-layer optical networks, multi-domain optical networks and elastic optical networks. We also present the interworking between OpenFlow and PCE/GMPLS control planes.
A novel scheme capable of dynamic wavelength assignment and burst contention mitigation is proposed to achieve efficient optical burst flow grooming in the OpenFlow controlled LOBS-over-WSON network. Simulation and experiment verified its feasibility.
Software defined networking and OpenFlow, which allow operators to control the network using software running on a network operating system within an external controller, provide the maximum flexibility for the operator to control a network, and match the carrier's preferences given its centralized architecture, simplicity, and manageability. In this paper, we report a field trial of an OpenFlow-based...
Elastic Optical Networks (EON), which are able to allocate an appropriate optical spectrum range and modulation format to an optical path according to the client (e.g. IP) traffic demand and path attributes (e.g., physical length or optical impairments), have been proposed to more efficiently utilize network spectrum resources. A control plane is a key enabling technique for dynamic and intelligent...
We present a node architecture and its control techniques for future terabit-class optical transport networks with the router offloading capability, which enables the cost-effectiveness and energy saving.
A unified control plane (UCP) for IP/Dense Wavelength Division Multiplexing (DWDM) multi-layer optical networks is a very important issue for network carriers. Generalized Multi-Protocol Label Switching (GMPLS), with a decade of development and standardization work, is a mature control plane technique for optical transport networks. But GMPLS-based UCP for IP/DWDM multi-layer networks is overly complex...
Control plane techniques are very important for optical networks since they can enable dynamic lightpath provisioning and restoration, improve the network intelligence, and greatly reduce the processing latency and operational expenditure. In recent years, there have been great progresses in this area, ranged from the traditional generalized multi-protocol label switching (GMPLS) to a path computation...
In the current IP/optical multi-layer networks, the control approaches for IP and optical domains are separated, which is inconvenient for the end-to-end service provisioning. Therefore, the investigation of a unified control plane for multi-layer networks is a very important issue for network carriers, since it can simplify the network manageability, improve the network agility and reduce the operational...
OpenFlow, which allows operators to control the network using software running on an external controller, provides the maximum flexibility for operators, and matches the carrier's preferences given its centralized architecture, simplicity and manageability. In this paper, we present an OpenFlow-based approach for dynamic wavelength path control in future photonic networks, assessing its overall feasibility...
We report a world first field trial of an OpenFlow-based unified control plane for multilayer multi-granularity optical networks, verifying its overall feasibility and efficiency, and quantitatively evaluating the latencies for end-to-end path creation and restoration.
In this paper, for the first time, we experimentally investigate OpenFlow-based reliable service provisioning and dynamic service differentiation in IP/DWDM multi-layer optical networks. All the solutions are experimentally demonstrated on a real testbed with both control and data planes, verifying their overall feasibility and efficiency, and quantitatively evaluating their performance.
With the deepening of the research of knowledge management, more and more scholars begin to study the Conversion of individual Knowledge and Organizational Knowledge from the interior of the enterprises. In the process of knowledge conversion, individuals and organization have promoted the conversion and application by means of cooperation to acquire market earning, however, at the time of income...
