Net-next haru, kuhu kogutakse muudatused tulevase Linuxi 6.16 versiooni jaoks, on vastu v\u00f5etud muudatus, mis k\u00f5rvaldab DCCP (Datagram Congestion Control Protocol) v\u00f5rgu protokolli toe. netfilter-moodulite tugi DCCP pakettide filtreerimiseks j\u00e4\u00e4b alles. DCCP protokoll standardiseeriti ja v\u00f5eti tuumasse 2006. aastal. Eeldati, et DCCP suurendab meediateenuste ja Interneti-telefoni efektiivsust \u00fclerahvastatud v\u00f5rkudes, kuid tegelikult ei leidnud protokoll laialdast rakendust. <\/p>\n

DCCP kood tuumas on viie aasta jooksul olnud toeta ja viimaste aastate muudatused on olnud piirdunud ainult API refaktorimisega seotud parandustega. M\u00f5ni aasta tagasi tehti Multipath DCCP projekti raames katse arendada DCCP prootokolli tuumas, kuid osa selle projekti koodist j\u00e4\u00e4b omaniku\u00f5iguste alla. Multipath DCCP arendaja kavatses avada omaniku\u00f5igustega osade koodi, edastada kogunenud muudatused tuuma p\u00f5hikoosseisu ja v\u00f5tta enda kanda DCCP hooldaja kohustused Linuxi tuumas, kuid ta ei ole juba mitu aastat \u00fchendust v\u00f5tnud. <\/p>\n

DCCP eemaldamine Linuxi tuumast k\u00f5rvaldab takistused, mis takistavad inet_connection_sock andmestruktuuri \u00fcmberehitamist, et suurendada TCP steki efektiivsust. Praegu jagatakse inet_connection_sock struktuuri TCP ja DCCP vahel, mis ei v\u00f5imalda TCP-le teatud optimeerimisi rakendada ilma DCCP koodi \u00fcmberehitamata. Eelk\u00f5ige inet_connection_sock struktuuri \u00fcmberkujundamine v\u00f5imaldab protsessorikasti t\u00f5husamat kasutamist kiirendatud pakettide t\u00f6\u00f6tlemisel juba loodud TCP \u00fchenduse jaoks (TCP fastpath).
