Ethernet Networks: Current Trends and Tools
Ethernet topology discovery has gained increasing interest in the recent
years. This trend is motivated mostly by increasing number of carrier Ethernet
networks as well as the size of these networks, and consequently the increasing
sales of these networks. To manage these networks efficiently, detailed and
accurate knowledge of their topology is needed. Knowledge of a network's
entities and the physical connections between them can be useful in various
prospective. Administrators can use topology information for network planning
and fault detecting. Topology information can also be used during protocol and
routing algorithm development, for performance prediction and as a basis for
accurate network simulations. From a network security perspective, threat
detection, network monitoring, network access control and forensic
investigations can benefit from accurate network topology information. In this
paper, we analyze market trends and investigate current tools available for
both research and commercial purposes.Comment: Proceedings of IEEE International Conference on Advanced Information

Ethernet Topology Discovery: A Survey
Ethernet networks have undergone impressive growth since the past few
decades. This growth can be appreciated in terms of the equipment, such as
switches and links, that have been added, as well as in the number of users
that it supports. In parallel to this expansion, over the past decade the
networking research community has shown a growing interest in discovering and
analyzing the Ethernet topology. Research in this area has concentrated on the
theoretical analysis of Ethernet topology as well as developing tools and
methods for mapping the network layout. These efforts have brought us to a
crucial juncture for Ethernet topology measurement infrastructures: while,
previously, these were both small (in terms of number of measurement points),
we are starting to see the deployment of large-scale distributed systems
composed of hundreds or thousands of monitors. As we look forward to this next
generation of systems, we take stock of what has been achieved so far. In this
survey, we discuss past and current mechanisms for discovering the Ethernet
topology from theoretical and practical prospective. In addition to discovery
techniques, we provide insights into some of the well known open issues related
to Ethernet topology discovery
