Software defined networking (SDN) over space division multiplexing (SDM) optical networks: features, benefits and
Optics Express
|March 26, 2014
Summary
We demonstrate the first Software-Defined Networking (SDN)-controlled optical network using spatial superchannels. SDN successfully manages dynamic bandwidth and quality of transmission (QoT) in flexible space division multiplexing (SDM) networks.
Area of Science:
- Optical Networking
- Telecommunications Engineering
- Network Control Systems
Background:
- Space Division Multiplexing (SDM) networks offer high capacity but require advanced control.
- Dynamic bandwidth and Quality of Transmission (QoT) provisioning are crucial for flexible optical networks.
Purpose of the Study:
- To demonstrate the first fully integrated Software-Defined Networking (SDN)-controlled, bandwidth-flexible, and programmable SDM optical network.
- To evaluate SDN's suitability for managing dynamic resource allocation and network slicing in SDM infrastructure.
Main Methods:
- Utilized sliceable self-homodyne spatial superchannels for data transmission.
- Implemented an SDN control plane for network management and resource provisioning.
- Tested dynamic bandwidth and QoT provisioning, infrastructure slicing, and isolation capabilities.
Main Results:
- Successfully demonstrated end-to-end bandwidth and QoT provisioning based on user requirements.
- Showcased the capability of SDN to manage the unique characteristics of the SDM infrastructure.
- Confirmed SDN's suitability as a control plane for high-capacity, flexible SDM networks.
Conclusions:
- SDN is a viable and effective control plane solution for advanced SDM optical networks.
- The demonstrated system supports dynamic resource allocation, network slicing, and isolation efficiently.
- Future high-capacity optical networks can benefit from SDN-based control for enhanced flexibility and programmability.

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.

Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:
