Network Virtualization on Optical Networks

2016 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2016
Network Virtualization is a simple method to implement multi vendor networks and is essential for Overlay Services in which Open Transport Switch (OTS), a light weight software switch is installed on transport switches for network resource. The control structure that supports the functionality of the different network protocols by separating the data ...

Virtual optical network provisioning in flexible bandwidth optical networks [PDF]

2015 14th International Conference on Optical Communications and Networks (ICOCN), 2015
In order to address the virtual optical network (VON) provisioning problem, VON mapping approaches, which include the power-aware virtual links mapping (PVLM) approach and the power-aware virtual nodes mapping (PVNM) approach, are developed to reduce power consumption for a given set of VONs.

Two use cases of machine learning for SDN-enabled ip/optical networks: traffic matrix prediction and optical path performance prediction [Invited]

IEEE\/OSA Journal of Optical Communications and Networking, 2018
We describe two applications ofmachine learning in the context of internet protocol (IP)/Optical networks. The first one allows agilemanagement of resources in a core IP/Optical network by using machine learning for shorttermand long-term prediction of ...

Optical Network Elements [PDF]

, 2008
The dramatic shift in optical-network architecture that began in the 2000 time frame is chiefly due to the development of advanced optical network elements. These elements are based on the premise that the majority of the traffic that enters a network site is being routed through the site en-route to its final destination as opposed to being destined ...

Introduction to Optical Networks [PDF]

, 2008
An optical network is composed of the fiber-optic cables that carry channels of light, combined with the equipment deployed along the fiber to process the light. There has been a gradual migration from an architecture where the optical network served simply as a collection of static pipes to one where it is viewed as another networking layer.

An optical switch, an optical network node and an optical network

2015
There is provided an optical switch. The optical switch comprises a first optical waveguide (10), a second optical waveguide (20), a first optical ring resonator (40) and a second optical ring resonator (50). The first optical ring resonator (40) is arranged between the first optical waveguide (10) and the second optical waveguide (20), wherein the ...

Virtual optical network embedding in multi-domain optical networks

2014 IEEE Global Communications Conference, 2014
We consider the problem of efficient virtual optical network (VON) mapping in a multi-domain optical network (VON-MD) with the objective of minimizing total network link cost for a given VON demand that is embedded over the multi-domain optical network.

Optical Network Design with Optical Constraints in IP/WDM Networks

IEICE Transactions on Communications, 2005
In this paper we consider algorithms for the logical topology design and traffic grooming problem in WDM networks with router interface constraints as well as optical constraints. The optical constraints include restricted transmission range due to optical impairments as well as limits on the number of available wavelengths.
