Abstract

Selon l'invention, des serveurs isolés ou des serveurs en grappes, notamment des serveurs web, déterminent la quantité de données traitées de manière concurrente par de tels serveurs, afin de maîtriser ainsi les performances de fonctionnement des serveurs. De préférence, un achemineur est interposé entre des clients et un ou plusieurs serveurs principaux, et il surveille les performances de chaque serveur principal (soit directement, soit d'une autre manière). De préférence également, l'achemineur détermine, pour chaque serveur principal, en réponse aux performances surveillées, soit le nombre de demandes de données traitées de manière concurrente, soit le nombre de connexions supportées de manière concurrente, soit les deux, afin de maîtriser les performances de ces serveurs principaux. Dans un mode de réalisation, l'achemineur utilise une bibliothèque de saisie de paquets aux fins de saisie de paquets au niveau de la couche 2 OSI et il met en oeuvre un protocole simplifié TCP/IP dans l'espace utilisateur (par opposition à l'espace noyau), afin de réduire la copie de données. De préférence, on emploie du matériel et des logiciels de système d'exploitation, disponibles sur le marché, pour tirer parti de leur rapport prix/performances.
