The (In)Security of Topology Discovery in Software Defined Networks

open access: yes2015 IEEE 40th Conference on Local Computer Networks (LCN), 2015
Topology Discovery is an essential service in Software Defined Networks (SDN). Most SDN controllers use a de-facto standard topology discovery mechanism based on Open-Flow to identify active links in the network. This paper discusses the security, or rather lack thereof, of the current SDN topology discovery mechanism, and its vulnerability to link ...

Efficient Topology Discovery for Software-Defined Networks

IEEE Transactions on Network and Service Management, 2021
OpenFlow discovery protocol (OFDP) is the standard protocol for discovering network topologies for OpenFlow. Each controller generates and receives OFDP messages for each switch to yield a network topology. However, for a network with a large number of switches, the controller may suffer from high overhead to perform OFDP even though the network ...

Topology-Efficient Discovery: A Topology Discovery Algorithm for Underwater Acoustic Networks

IEEE Journal of Oceanic Engineering, 2018
In this paper, we describe topology-efficient discovery (TED), the first designated topology-efficient discovery algorithm for underwater acoustic networks. Topology information is essential for network operations. By knowing the network topology, information sources can determine destination nodes and routing possibilities for their packets and ...

Network Topology Discovery Based on SNMP

2013 Ninth International Conference on Computational Intelligence and Security, 2013
This paper proposes a network topology discovery algorithm and detailed implementation process. The paper introduces several kinds of centralized discovery technologies for network topology, and puts forwards a network topology discovery improvement algorithm. In the algorithm implementation, the authors independently design a software development kit (

Topology Discovery for Public IPv6 Networks

Computer Communication Review, 2003
In just three decades the Internet has grown from a small experimental research network into a complex network of routers, switches, and hosts. Understanding the topology of such large scale networks is essential to the procurement of good architectural design decisions, particularly with respect to address allocation and distribution schemes.A number ...

Topology discovery of Synchronous Optical NETworks

2017 International Conference on Computing, Networking and Communications (ICNC), 2017
Telecommunication 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 ...

Decentralized discovery of camera network topology

2008 Second ACM/IEEE International Conference on Distributed Smart Cameras, 2008
One 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
