Topology discovery of Synchronous Optical NETworks
2017 International Conference on Computing, Networking and Communications (ICNC), 2017Telecommunication networks are comprised of interconnected network elements which provide communication services to end users. The port-to-port connectivity of these network elements is referred to as the network topology. Due to the ever growing demand, these networks undergo frequent changes in their topology as new fiber optic links, nodes and ...

Improving the Efficiency of Network Topology Discovery
2008 The 3rd International Conference on Grid and Pervasive Computing - Workshops, 2008As wireless and mobile networks are getting more of a commonplace, the discovery and management of dynamic networks has become a serious issue.. Since the topology of wireless and mobile networks always keeps changing, the key issue of topology discovery is how to effectively and efficiently perform the discovery task with minimal impact to normal ...

Decentralized discovery of camera network topology
2008 Second ACM/IEEE International Conference on Distributed Smart Cameras, 2008One of the primary uses of camera networks is the observation and tracking of objects within some domain. Substantial research has gone into tracking objects within single and multiple views. However, few such approaches scale to large numbers of sensors, and those that do require an understanding of the network topology. Camera network topology models

Topology discovery in heterogeneous IP networks
Proceedings IEEE INFOCOM 2000. Conference on Computer Communications. Nineteenth Annual Joint Conference of the IEEE Computer and Communications Societies (Cat. No.00CH37064), 2002Knowledge of the up-to-date physical topology of an IP network is crucial to a number of critical network management tasks, including reactive and proactive resource management, event correlation, and root-cause analysis. Given the dynamic nature of today's IP networks, keeping track of topology information manually is a daunting (if not impossible ...

Incremental unsupervised topological place discovery
2014 IEEE International Conference on Robotics and Automation (ICRA), 2014This paper describes an online place discovery and recognition engine that fuses information over time to create topologically distinct places. A key motivation is the recognition that a single image may be a poor exemplar of what constitutes a place. Images are not ‘places’ nor are they ‘documents’. Instead, by treating image-sequences as a multimodal

Topological field theory and the discovery of topological materials
Physica Scripta, 2012Topological field theory (TFT) describes universal low-energy properties of topological states of quantum matter. It also predicts exact quantization effects that can be experimentally measured. Recently, TFT has directly led to the theoretical prediction of topological materials. In this paper, I shall briefly review these recent developments.

Radon – Rapid Discovery of Topological Relations
Proceedings of the AAAI Conference on Artificial Intelligence, 2017Geospatial data is at the core of the Semantic Web, of which the largest knowledge base contains more than 30 billions facts. Reasoning on these large amounts of geospatial data requires efficient methods for the computation of links between the resources contained in these knowledge bases.

Ethernet Topology Discovery for Networks with Incomplete Information
2007 16th International Conference on Computer Communications and Networks, 2007In this paper we investigate the problem of finding a layer-2 network topology when the information available from SNMP MIB is incomplete. We prove that finding a network topology in this case is NP-hard. We further prove that deciding whether the given information defines a unique network topology is a co-NP-hard problem.

Monitoring and evaluating the performance of a network is essential to detect and resolve network failures. In order to achieve this monitoring level, it is essential to know the topology of the network which is often unknown. Many of the techniques used to discover the topology require the cooperation of all network devices, which is almost impossible

A hierarchical topology discovery service for IPv6 networks
NOMS 2002. IEEE/IFIP Network Operations and Management Symposium. ' Management Solutions for the New Communications World'(Cat. No.02CH37327), 2003Being able to maintain an accurate image of the network topology is one of the basic requirements of any management solution. While the solution to this requirement is not obvious in IPv4 networks, it becomes even harder when IPv6 is deployed. The huge address space which prevents the use of any iterative method is, among others, a feature that makes ...
