Le support des modules netfilter pour la filtration des paquets DCCP est maintenu. Le protocole DCCP a \u00e9t\u00e9 normalis\u00e9 et int\u00e9gr\u00e9 au noyau en 2006. On esp\u00e9rait que DCCP am\u00e9liorerait l'efficacit\u00e9 de la diffusion et de la t\u00e9l\u00e9phonie internet dans les r\u00e9seaux surcharg\u00e9s, mais en r\u00e9alit\u00e9, le protocole s'est av\u00e9r\u00e9 peu sollicit\u00e9 et n'a pas trouv\u00e9 d'usage \u00e9tendu.      <\/p>\n<p> Le code DCCP dans le noyau n'est plus maintenu depuis cinq ans, et les modifications ces derni\u00e8res ann\u00e9es \u00e9taient limit\u00e9es \u00e0 des corrections dues \u00e0 un refactoring de l'API du noyau. Il y a quelques ann\u00e9es, dans le cadre du projet Multipath DCCP, une tentative de d\u00e9veloppement du protocole DCCP dans le noyau a \u00e9t\u00e9 faite, mais une partie du code de ce projet reste propri\u00e9taire. Le d\u00e9veloppeur de Multipath DCCP pr\u00e9voyait d'ouvrir le code des parties propri\u00e9taires, de transf\u00e9rer les modifications accumul\u00e9es dans la version principale du noyau et de prendre en charge le maintien de DCCP dans le noyau Linux, mais cela fait d\u00e9j\u00e0 plusieurs ann\u00e9es qu'il n'est plus en contact.      <\/p>\n<p>La suppression de DCCP du noyau Linux supprimera les obstacles \u00e0 la refonte de la structure de donn\u00e9es inet_connection_sock pour am\u00e9liorer l'efficacit\u00e9 de la pile TCP. Actuellement, la structure inet_connection_sock est utilis\u00e9e conjointement dans TCP et DCCP, ce qui emp\u00eache la mise en \u0153uvre de certaines optimisations pour TCP sans retravailler le code DCCP. En particulier, la refonte de la structure inet_connection_sock permettra une utilisation plus efficace du cache processeur lors du traitement acc\u00e9l\u00e9r\u00e9 des paquets pour une connexion TCP d\u00e9j\u00e0 \u00e9tablie (TCP fastpath).<br \/>\n<br \/>Source : <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=63096\">opennet.ru<\/a>
