Status and Trends for Standardization of Architecture and Solutions for Multi-Domain Optical Networks

چکیده
Optical technologies form the key foundations for transport networks used by all major telecommunication carriers. Those networks are made up of equipment supplied by different manufacturers, and utilize different optical switching and transmission technologies. These give rise to distinct islands or "domains" of network nodes of different capabilities. Further, administrative segmentation of networks, and inter-carrier communications add another concept of a domain. Control plane technologies have seen increasing popularity as a way of discovering transport network capabilities and provisioning connectivity across them. To date, the focus has been on control plane operations within optical domains, but attention is now turning to the operation of multi-domain optical networks. This paper sets out the current status and trends in standardization of control plane architectures and technologies for use in multi-domain optical networks.

The purpose of multi-focus image fusion is gathering the essential information and the focused parts from the input multi-focus images into a single image. These multi-focus images are captured with different depths of focus of cameras. A lot of multi-focus image fusion techniques have been introduced using considering the focus measurement in the spatial domain. However, the multi-focus image ...
متن کاملQuery Architecture Expansion in Web Using Fuzzy Multi Domain Ontology
Due to the increasing web, there are many challenges to establish a general framework for data mining and retrieving structured data from the Web. Creating an ontology is a step towards solving this problem. The ontology raises the main entity and the concept of any data in data mining. In this paper, we tried to propose a method for applying the "meaning" of the search system, But the problem ...
