À mesure que le nombre d'applications Internet dans des situations critiques augmente, l'assurance qualité de l'infrastructure réseau devient de plus en plus importante. Les opérateurs de tels réseaux doivent maintenir le réseau aussi fiable et disponible avec des performances suffisantes. La technologie de mesure est la clé du maintien de l’état du réseau et fait du réseau l’infrastructure importante de la société en réseau. Pour répondre à ces exigences, un compteur IP rapide et précis, LUI, a été développé. Un matériel spécifique a été conçu pour réaliser les spécifications nécessaires permettant la capture de données avec des informations de synchronisation d'ordre de 20 µsecondes à partir d'un réseau de classe Gigabit. Les résultats expérimentaux avec LUI montrent que : 1) les équipements logiciels ne peuvent pas gérer les informations de synchronisation d'ordre de 100 µsecondes, 2) le système informatique actuel peut transmettre un flux multimédia à haute vitesse (30 Mpbs) avec une synchronisation précise (gigue inférieure à 20 µsecondes) avec UDP, 3 ) mais le mécanisme de retransmission de TCP aggrave la gigue (jusqu'à 264 mil secondes) et, 4) le trafic unidirectionnel du WAN présente un comportement étrange, qui nécessite une enquête plus approfondie.

Abstract: As the number of Internet applications in critical situations increases, the quality assurance of the network infrastructure becomes more and more important. The operators of such networks have to maintain the network as reliable and available with sufficient performance. Measurement technology is the key to maintaining the network condition and provides the network as being the important infrastructure of the network society. To meet these requirements, a high-speed and accurate IP meter, HIM, has been developed. Specific hardware has been made to realize the necessary specifications that enable data capturing with 20-µsecond order timing information from a gigabit class network. The experimental results with HIM show that: 1) software-based equipment cannot handle 100-µsecond order timing information, 2) the current computer system can transmit a high-speed (30 Mpbs) multimedia stream in accurate timing (jitter less than 20 µseconds) with UDP, 3) but TCP's retransmission mechanism makes the jitter worse (up to 264 mil seconds) and, 4) WAN's one-way traffic exhibits some strange behavior, which requires further investigation.
