I net-next-grenen, hvor \u00e6ndringer samles til fremtidige versioner af Linux-kernen 6.16, er der vedtaget en \u00e6ndring, der fjerner underst\u00f8ttelsen af netv\u00e6rksprotokollen DCCP (Datagram Congestion Control Protocol). Underst\u00f8ttelsen af netfilter-moduler til DCCP-pakke filtrering bevares. DCCP-protokollen blev standardiseret og indf\u00f8rt i kernen i 2006. Det blev antaget, at DCCP ville forbedre effektiviteten af streaming og internet-telefoni i overbelastede netv\u00e6rk, men i praksis viste protokollen sig ikke at v\u00e6re efterspurgt og opn\u00e5ede ikke udbredelse. <\/p>\n

DCCP-koden i kernen har ikke v\u00e6ret vedligeholdt i fem \u00e5r, og \u00e6ndringerne de seneste \u00e5r har v\u00e6ret begr\u00e6nset til fejlrettelser p\u00e5 grund af omstruktureringer af API'en i kernen. For nogle \u00e5r siden blev der inden for Multipath DCCP-projektet gjort et fors\u00f8g p\u00e5 at udvikle DCCP-protokollen i kernen, men en del af koden fra dette projekt forbliver propriet\u00e6r. Udvikleren af Multipath DCCP havde planer om at \u00e5bne den propriet\u00e6re kode, overf\u00f8re de akkumulerede \u00e6ndringer til den prim\u00e6re kerne og p\u00e5tage sig vedligeholdelsen af DCCP i Linux-kernen, men han har ikke v\u00e6ret i kontakt i flere \u00e5r. <\/p>\n

Fjernelsen af DCCP fra Linux-kernen vil fjerne hindringerne for at omarbejde datakonstruktionen inet_connection_sock for at forbedre effektiviteten af TCP-stakken. I \u00f8jeblikket deles datakonstruktionen inet_connection_sock mellem TCP og DCCP, hvilket forhindrer nogle optimeringer for TCP uden at omarbejde DCCP-koden. Is\u00e6r vil omarbejdningen af inet_connection_sock-strukturen give mulighed for en mere effektiv udnyttelse af CPU-cachen ved hurtigere behandling af pakker til en allerede etableret TCP-forbindelse (TCP fastpath).
