Kutshanje se wakhupha inguqulelo entsha ye-DentOS 2.0 equka inkxaso yeMarvell kunye neMellanox arm64 kunye ne-amd64 kunye ne-MAC / ASiC iinkqubo, ukuphuculwa kokuhambelana, kunye nokunye.
Kwabo bangayaziyo le nkqubo, bafanele bayazi loo nto Isekwe kwi-Linux kernel kwaye yenzelwe ukuxhobisa iiswitshi, iirotha, kunye nezixhobo ezikhethekileyo zenethiwekhi. Uphuhliso lwenziwa ngokuthatha inxaxheba kwe-Amazon, i-Delta Electronics, i-Marvell, i-NVIDIA, i-Edgecore Networks kunye ne-Wistron NeWeb (WNC). Ekuqaleni, iprojekthi yayixhaswa ngemali yi-Amazon ukuxhobisa izixhobo zenethiwekhi kwiziseko zayo.
Malunga neDentOS
Ukulawula ukutshintshwa kwepakethi kwi-DentOS, Indlela esezantsi yeSwitchDev ye Linux kernel iyasetyenziswa, ekuvumela ukuba wenze abaqhubi bokutshintsha kwe-Ethernet abanokunikezela ngesakhelo sokuthumela phambili kunye nokusetyenzwa kwepakethi yenethiwekhi kwiichips ezikhethekileyo zehardware.
I-Software padding isekelwe kwi-standard ye-Linux networking stack, i-NetLink subsystem, kunye nezixhobo ezifana ne-IPRoute2, i-tc (ulawulo lwezithuthi), i-brctl (ulawulo lwebhulorho), kunye ne-FRrouting, kunye ne-VRRP (i-Virtual Router Redundancy Protocol) , i-LLDP (ikhonkco umaleko). INkqubo yokuFumana) kunye ne-MSTP (iProtokholi yeMithi eNyenziwe kaninzi).
Inkqubo yemo engqongileyo isekwe kunikezelo lwe-ONL (Vula iNethiwekhi yeLinux), ethi yona isebenzisa isiseko seDebian GNU/Linux package kwaye ibonelela ngesifakeli, ulungelelwaniso, kunye nabaqhubi ukuba baqhube kwiiswitshi.
I-ONL iphuhliswe yiprojekthi yeKhompyutha eVulekileyo kwaye liqonga lokudala izixhobo zenethiwekhi ezikhethekileyo ezixhasa ukufakwa kwiimodeli zokutshintsha ezingaphezu kwekhulu. Iquka abaqhubi ukuba bajongane nezibonakaliso ezisetyenziselwa ukutshintsha, izinzwa zeqondo lokushisa, ii-coolers, iibhasi ze-I2C, i-GPIOs, kunye nee-transceivers ze-SFP.
Kulawulo, ungasebenzisa i-IpRoute2 kunye nezixhobo ze-ifupdown2, kunye ne-gNMI (gRPC Network Management Interface). YANG (Kusesinye isiZukulwana esilandelayo, i-RFC-6020 ) imifuziselo yedatha isetyenziselwa ukuchaza uqwalaselo.
Izinto ezintsha eziphambili zeDentOS 2.0
Kolu guqulelo lutsha, ukongeza ekuhambelaneni neenkqubo esele zikhankanyiwe ekuqaleni, sinokufumana inkxaso ukuhambelana ne-NAT-44 kunye ne-NA(P)T uguqulelo lwedilesi (NAT) ukusuka kuluhlu lwangaphakathi ukuya kwiidilesi zoluntu kwinqanaba lezibuko eziqhelekileyo (umaleko 3, umaleko womnatha) kunye namazibuko eVLAN (iibhulorho zothungelwano) kwiswitshi.
Kuyacaciswa ukuba inkxaso eyongeziweyo kubalawuli be-PoE (Amandla phezu kwe-Ethernet) kuMandla phezu kolawulo lwe-Ethernet.
Ukongezelela, utshintsho luye lwenziwa ukuphucula ukusebenza kunye nokunciphisa ukucwangciswa kwe-firewall, kunye nokuphuculwa kolawulo lwe-ACL-based based resource management.
Kwelinye icala, nayo kuqatshelwe ukuba ukukwazi ukudibanisa abalawuli kunikezelwe isiko ukuqwalasela ukwahlulwa kwezibuko.
Kolunye utshintsho olugqamileyo kolu guqulelo lutsha lwe-DentOS 2.0:
- Inkxaso eyongeziweyo yeeflegi ukuqaphela iidilesi ze-IP zendawo (intranethi).
- Inika iinketho zokuqwalasela i-802.1Q i-interfaces yenethiwekhi (VLANs) kunye nokuhamba kwe-traffic kubo.
- Iipakethi ze-IpRoute2 kunye ne-Ifupdown2 zisetyenziselwa uqwalaselo.
- Ngokusekelwe kwi "devlink", i-API yokufumana ulwazi kunye nokutshintsha iiparamitha zesixhobo kuphunyezwa, inkxaso yeendawo zokubala zomgibe wendawo kunye neepakethi eziwisiweyo ziphunyeziwe.
Gqibela ukuba unomdla wokwazi okungakumbi ngayo, ungajonga iinkcukacha Kule khonkco ilandelayo. Ikhowudi ye-DentOS ibhalwe kwi-C kwaye isasazwe phantsi kweLayisensi yoLuntu ye-Eclipse.
Khuphela kwaye ufumane i-dentOS 2.0 Beeblebrox
Kwabo banomdla wokukwazi ukuvavanya le nkqubo, kufuneka bayazi loo nto iyafumaneka kwi-Marvell kunye ne-Mellanox ASIC esekelwe kwiiswitshi kunye ukuya ku 48 10 izibuko gigabit.
ngaphandle koko sebenza ngee-ASIC ezahlukeneyo kunye neetshiphu zokusetyenzwa kwedatha yenethiwekhi ziyaxhaswa, kuquka i-Mellanox Spectrum, i-Marvell Aldrin 2, kunye ne-Marvell AC3X ASICs kunye nokuphunyezwa kweetafile zokuhambisa ipakethe ye-hardware.
I-DentOS esele ilungele ukuhlohla ilungiselelwa i-ARM64 (257 MB) kunye ne-AMD64 (523 MB) yezakhiwo kunye nemifanekiso yenkqubo inokufumaneka. kwikhonkco elingezantsi.
