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 ...

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 ...

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.

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 ...

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

Automatic Discovery of Physical Topology in Ethernet Networks
22nd International Conference on Advanced Information Networking and Applications (aina 2008), 2008Ethernet is becoming increasingly popular in metro and access networks due to the high bandwidth available at low cost. Nonetheless, native Ethernet lacks some features that are important for sophisticated network management; providing accurate knowledge on the physical topology is one of them.

An algorithm for automatic topology discovery of IP networks
ICC '98. 1998 IEEE International Conference on Communications. Conference Record. Affiliated with SUPERCOMM'98 (Cat. No.98CH36220), 2002A topology discovery algorithm for IP networks is proposed. Topology configuration information can be obtained from various sources including the MIBs in routers and gateways, the Internet Control Message Protocol (ICMP), the traceroute program, the Domain Name System (DNS), and etc.

Automatic topology discovery in software defined networks
2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014An algorithm on automatic topology discovery in OpenFlow supported software defined networks is proposed. The proposed algorithm utilizing link layer discovery protocol allows to obtain the whole network topology by the network controller. We have validated the successful operation of our algorithm through simulation and real network tests seperately ...
