Intel on avanud t\u00f6\u00f6riistakomplekti, mis v\u00f5imaldab luua oma rakendusi pakettide t\u00f6\u00f6tlemiseks programmeeritavates Ethernet-l\u00fclitites seerias Tofino. Apache 2.0 litsentsi all on avatud koodi tagumine osa P4C kompilaatorile ja Intel P4 Studio arenduskeskkonna komponentide, n\u00e4iteks draiverite, l\u00fcliti simulatsiooni mudeli, BF Runtime protokolli serveri ja kliendi jaoks. Rakenduste loomisel kasutatakse domeenispetsiifilist programmeerimiskeelt P4 (Programming Protocol-independent Packet Processors), mis on m\u00f5eldud pakettide t\u00f6\u00f6tlemise loogika m\u00e4\u00e4ratlemiseks v\u00f5rguseadmetes, nagu v\u00f5rgukaardid, l\u00fclitid, marsruuterid ja tulem\u00fc\u00fcrid. <\/p>\n

Avaldatud tagumine osa v\u00f5imaldab P4 keeles kirjutatud programme konverteerida esituseks, mis on sobiv Intel Tofino seeria l\u00fclititele. T\u00e4nu sellele saavad l\u00fclitite kasutajad luua rakendusi, mis laiendavad vahelduvaid funktsioone, muudavad t\u00f6\u00f6loogikat v\u00f5i kohandavad seadet oma v\u00f5rkude spetsiifikale. <\/p>\n

P4 keeles kirjutatud programmid kompileeritakse sihtplatvormide esitusteks, mis v\u00f5ivad olla nii riistvaraliselt (FPGA, programmeeritavad ASIC) kui ka tarkvaraliselt (x86, BPF). Koos sihts\u00fcsteemidele installimiseks m\u00f5eldud koodiga genereerib kompilaator rakenduse haldamiseks talletuse protokollidele Protobuf\/gRPC ja P4Runtime API. <\/p>\n

Programmi t\u00fc\u00fcpiline t\u00f6\u00f6loogika seisneb pakettide klassifitseerimises nende peade p\u00f5hjal ning sisenevatele pakettidele toimingute, nagu suunamine, tagasil\u00fckkamine, TTL muutmine ja v\u00e4ljade asendamine, tegemises. Keel ei ole seotud v\u00f5rguprotokollidega ning sisse ehitatud toetuse asemel t\u00fc\u00fcpilistele protokollidele, nagu IP, Ethernet, TCP ja VxLAN, annab arendajatele v\u00f5imaluse m\u00e4\u00e4ratleda igasuguseid protokolle kompileeritavate rakenduste kontekstis (arendaja lisab peaformaatide ja protokolliv\u00e4ljade kirjeldused).

\"Ava<\/center> <\/p>\n

Lisaks Intel Tofino l\u00fclitite jaoks avaldatud tagumisele osale pakub P4 projekt tagumist osa P4 rakenduste kompileerimiseks C keeles, mida saab seej\u00e4rel kompileerida vormingusse, mis on sobivaks k\u00e4itamiseks virtuaalses masinas<\/a> eBPF Linuxi tuumas. Projekt arendab ka avatud l\u00fcliti simulaatorit, mida saab kasutada katsetamiseks virtuaalses v\u00f5rgus Mininet, ning tagumist osa P4 programmide kompileerimiseks simulaatorile.
