The purpose of this paper is to present SMARTxAC, a tailor‐made passive monitoring and analysis system for high‐speed IP networks. The authors also discuss the design challenges we had to face to cope with the requirements of such a system.

This system has been designed to operate at gigabit speeds without packet loss, while providing very detailed information about the network usage.

SMARTxAC has become a very powerful tool for the network operators of the Catalan Research and Education Network (Anella Científica) to know, in detail, the usage of their network and to detect network faults, anomalies and attacks when they occur.

In the design of this system, the authors had to trade generality for performance in order to address the current limitations of monitoring high‐speed links.

Since 2003, SMARTxAC has been used for continuously monitoring the Anella Científica.

The main difference between SMARTxAC and other monitoring systems and infrastructures for high‐speed networks is that SMARTxAC has been explicitly designed to analyse the network traffic online, whereas in other approaches, traffic analysis tasks are usually postponed to an off‐line stage.

The purpose of this paper is to propose a methodology for assessing thesauri and other controlled vocabularies management tools that can represent content using the Simple Knowledge Organization System (SKOS) data model, and their use in a Linked Open Data (LOD) paradigm. It effectively analyses selected set of tools in order to prove the validity of the method.

A set of 27 criteria grouped in five evaluation indicators is proposed and applied to ten vocabulary management applications which are compliant with the SKOS data model. Previous studies of controlled vocabulary management software are gathered and analyzed, to compare the evaluation parameters used and the results obtained for each tool.

The results indicate that the tool that obtains the highest score in every indicator is Poolparty. The second and third tools are, respectively, TemaTres and Intelligent Theme Manager, but scoring lower in most of the evaluation items. The use of a broad set of criteria to evaluate vocabularies management tools gives satisfactory results. The set of five indicators and 27 criteria proposed here represents a useful evaluation system in the selection of current and future tools to manage vocabularies.

The paper only assesses the ten most important/well know software tools applied for thesaurus and vocabulary management until October 2016. However, the evaluation criteria could be applied to new software that could appear in the future to create/manage SKOS vocabularies in compliance with LOD standards.

The originality of this paper relies on the proposed indicators and criteria to evaluate vocabulary management tools. Those criteria and indicators can be valuable also for future software that might appear. The indicators are also applied to the most exhaustive and qualified list of this kind of tools. The paper will help designers, information architects, metadata librarians, and other staff involved in the design of digital information systems, to choose the right tool to manage their vocabularies in a LOD/vocabulary scenario.
