Linux 6.16 tuuma tulevasse v\u00e4ljalaskesse lisanduva net-next haru muudatuste hulka kuulub muudatus, mis eemaldab DCCP (Datagram Congestion Control Protocol) v\u00f5rguprotokolli toe. Netfilter moodulite tugi DCCP pakettide filtreerimiseks s\u00e4ilitati. DCCP protokoll standardiseeriti ja lisati tuuma 2006. aastal. Oletati, et DCCP suurendab voogesituse ja Interneti-telefonide efektiivsust \u00fclekoormatud v\u00f5rkudes, kuid tegelikult ei leidnud protokoll laialdast rakendust. <\/p>\n

DCCP kood tuumas on olnud hoolduseta juba viis aastat ning viimaste aastate muudatused on piirdunud ainult tuuma API refaktoreerimisega seotud parandustega. Mitu aastat tagasi tehti Multipath DCCP projekti raames katse DCCP protokolli arendamiseks tuumas, kuid osa selle projekti koodist j\u00e4\u00e4b omandi\u00f5igusega. Multipath DCCP arendaja kavatses avada omandi\u00f5iguslikud osad, edastada pikaajalised muudatused tuuma p\u00f5hikoosseisu ning v\u00f5tta endale DCCP haldaja kohustused Linuxi tuumas, kuid ta ei ole juba mitu aastat \u00fchendust v\u00f5tnud. <\/p>\n

DCCP eemaldamine Linuxi kernelist k\u00f5rvaldab takistused, mis takistavad inet_connection_sock andmestruktuuri \u00fcmberkujundamist TCP stacki efektiivsuse t\u00f5stmiseks. Hetkel, kuna inet_connection_sock struktuuri jagavad nii TCP kui ka DCCP, ei ole v\u00f5imalik TCP-le teatud optimeeringuid rakendada ilma DCCP koodi \u00fcmbertegemiseta. \u00dcmberkujundamine inet_connection_sock struktuuris v\u00f5imaldab t\u00f5husamalt kasutada protsessori vahem\u00e4lu kiirendatud pakettide t\u00f6\u00f6tlemise ajal juba loodud TCP \u00fchenduse (TCP fastpath) korral.
