Mubisanzwe bya NPB, ikibazo giteye ubwoba kubayobozi ni igihome cyipaki cyatewe no kwiyongera kw'ikipaki cya ndored na npb. Igihombo cya Packet muri NPB gishobora gutera ibimenyetso bisanzwe bikurikira-byanyuma byo gusesengura inyuma:
- Impuruza yatanzwe mugihe ibimenyetso bya serivisi ya APM igabanyijemo, kandi ibikorwa byo gutsinda bigabanuka bigabanuka
- Urusobe rwa NPM rukurikirana ibimenyetso bidasanzwe birateganijwe
- Sisitemu yo gukurikirana umutekano yananiwe kumenya ibitero bitewe no gusiba ibyabaye
- Gutakaza ibikorwa bya serivisi byakozwe na sisitemu yo kugenzura serivisi
... ...
Nka sisitemu yo gufatwa hamwe no gukwirakwiza igenzura rya Bypass, akamaro ka NPB ni ubwawe. Mugihe kimwe, uburyo butunganya amakuru yimodoka itandukana numuyoboro gakondo nzima, hamwe na tekinoroji yo kugenzura imihanda ya serivisi zizima ntabwo ikoreshwa kuri NPB. Nigute ushobora gukemura igihombo cya NPB, reka duhere kumizi ituma isesengura ryamapaki kugirango tuyibone!
NPB / Kanda igihome cyigihe cyimizi yiyongera
Mbere ya byose, turasesengura inzira nyayo yumuhanda hamwe nubusabane bwo gushushanya hagati ya sisitemu hamwe ninyungu kandi gusohoka kurwego rwa 1 cyangwa urwego NPB. Ntakibazo cyaba umuyoboro wa topologiya ya topologiya, nka sisitemu yo gukusanya, hari byinshi-byinjiza traffic-byinshi byinjiza hamwe no gusohoka hagati ya "kwinjira" na "ibisohoka" bya sisitemu yose.
Noneho tureba icyitegererezo cyubucuruzi cya NPB kubitekerezo bya chipi ya asic ku gikoresho kimwe:
Ikiranga 1: "Traffic" n "" Umubare wumubiri "winjiza hamwe nimikorere yo gusohoka ni ubuso bwa micro-burts ni ibisubizo byanze bikunze. Mubisanzwe byinshi-kuri-imwe cyangwa byinshi-kuri-byinshi-byinshi-byinshi-byinshi byimikorere ya interineti isanzwe ni ntoya kuruta igipimo cyuzuye cyumubiri winjiza. Kurugero, imiyoboro 10 ya 10G hamwe numuyoboro 1 wibisohoka 10G; Muburyo bwinshi bwo kohereza, NPBBS zose zirashobora kubonwa muri rusange.
Ibiranga 2: Asic Chip Cache Umutungo ni muto cyane. Kubijyanye na chip ya asic izwi cyane, chip hamwe na 640GBPS ubushobozi bwo kuvunja bufite cache ya 3-10MBYTES; A 3.2TBps ubushobozi bwa chip ifite cache ya 20-50. Harimo Broadcom, ibirenge byambaye ibirenge, CTC, Marvell hamwe nabandi bakorera chip ya asic.
Ibiranga 3: Uburyo bwo kugenzura ibintu bisanzwe bwo kugerwaho na PFC ntabwo bukoreshwa kuri serivisi za NPB. Intangiriro yinkunga yo kugenzura PFC ni ukugera kubitekerezo byo guhagarika imikino yo guhagarika imihanda, hanyuma ugabanye kohereza paki kumapaki yitumanaho kugirango ugabanye ubwinshi. Ariko, isoko ya Packel ya serivisi za NPB ni udupaki za firime, bityo ingamba zo gutunganya zirashobora gutabwa gusa cyangwa zavuza.
Ibikurikira ni isura isanzwe isanzwe yaturika kumurongo utemba:
Gufata Imigaragarire ya 10G nkurugero, murwego rwa kabiri traffic traflof isesengura igishushanyo, igipimo cyumuhanda kibungabungwa nka 3GBPS kuva kera. Ku mbonerahamwe ya milaisecond yerekana imbonerahamwe, imihanda ya spike (microburst) yarenze cyane igipimo cya 10G.
Tekinike yingenzi yo kugabanya mikorobe ya NPB
Gabanya ingaruka zinganda zidasanzwe zidasanzwe zidasanzwe zidashoboka- Mugihe ushushanya umuyoboro, gabanya ibitekerezo byihuta kandi usohokamo interineti yumubiri bishoboka. Uburyo busanzwe ni ugukoresha igipimo cyo hejuru cya UPLANK
Hindura politiki yo gucunga cache ya serivisi ya NPB- Politiki isanzwe yubuyobozi ireba serivisi yo guhinduranya ntabwo ikoreshwa muri serivisi yo kohereza muri serivisi ya NPB. Politiki yo gucunga cache ingwate yishimye + kugabana imbaraga bigomba gushyirwa mubikorwa bishingiye kubiranga serivisi ya NPB. Kugirango ugabanye ingaruka za NPB microBerst munsi yimpapuro zigezweho.
Gushyira mu bikorwa imicungire yubuhanga. Menya neza ko umubare wibanze wa Queies zishingiye ku cyiciro cya Quee
Igisubizo cya sisitemu ishyize mu gaciro izamura ikarita ya packet hamwe nubushobozi bwo guhinduranya traffic- Kwinjiza igisubizo ukoresheje uburyo butandukanye bwo kwagura paki caltable ubushobozi bwa chip ya asic. Muguhindura ingendo ahantu hatandukanye, micro-burting ihinduka micro-imyenda igabanuka nyuma yo guhinduranya.
Guhuza ™ Micro yaturika igisubizo cyo gucunga umuhanda
Gahunda ya 1 - Umuyoboro-Oroshye Ingamba zo kuyobora cache + Umuyoboro-ubugari bwimikorere yibanze
Ingamba zo gucunga cache zihitamo umuyoboro wose
Ukurikije imyumvire yimbitse ya serivisi ya serivisi na serivisi zubucuruzi hamwe nubucuruzi bufatika bwabakiriya benshi, ibicuruzwa byo gukusanya ibikoresho byagaciro bya NPB. Kwihangana kwa Microburts bigaragaye kurwego ntarengwa iyo fip ya chip ya asic ikosowe.
Microshye Gutunganya Ikoranabuhanga - Ubuyobozi bushingiye ku byo imbere
Iyo ishami rifata traffict ryoherejwe ryigenga, irashobora kandi gushyirwa imbere ukurikije akamaro k'ibikoresho byo gusesengura inyuma cyangwa akamaro kamakuru ya serivisi ubwayo. Kurugero, mubikoresho byinshi byasesengura, APM / BPC ifite umwanya wambere kuruta gusesengura umutekano / ibikoresho byumutekano kuko birimo gukurikirana no gusesengura amakuru atandukanye ya sisitemu yubucuruzi. Kubwibyo, kubwibi bintu bisabwa na APM / BPC birashobora gusobanurwa nkuko hashobora gukurikiranwa no gukurikirana umutekano / ibikoresho byo gusesengura umutekano bishobora gucirwa bugufi, kandi amakuru asabwa nibikoresho byo gusesengura birashobora gusobanurwa. Iyo ibipaki byakusanyirijwe hamwe byinjira ku cyambu cyinjiza, ibyihutirwa bisobanurwa ukurikije akamaro k'ipaki. Ibipaki byihutirwa byoherejwe mbere nyuma yipaki yibanze yoherewe, kandi paki yibindi byingenzi byoherezwa nyuma yipaki yihutirwa zoherezwa. Niba udupaki twibanze dukomeje kuhagera, udupaki dushyira imbere imbere. Niba amakuru yinjiza arenze ubushobozi bwo kohereza ibyambu bishaje mugihe kirekire, amakuru arenze ibitswe muri cache yigikoresho. Niba cache yuzuye, igikoresho gitesha agaciro udupaki duto. Ubu buryo bwo gucunga uburyo bwambere bwemeza ko ibikoresho byingenzi byo gusesengura bishobora kubona neza amakuru yumwimerere asabwa mugusesengura mugihe nyacyo.
Ikoranabuhanga ryo gutunganya imiterere - Uburyo bwo gushimangira ingwate yimiyoboro yose
Nkuko bigaragara ku gishushanyo cyavuzwe haruguru, tekinoroji yo gupima umuhanda ikoreshwa mu gutandukanya serivisi zitandukanye kubikoresho byose kurwego, igiteranyo / urwego rwibanze, hamwe nibyihutirwa bya paki yafashwe. Umugenzuzi wa SDN atanga politiki yibanze mu buryo bwo gushyira mu gaciro kandi ikoresha ibikoresho byo kohereza. Ibikoresho byose bitabira imiyoboro bishushanyijeho umurongo utandukanye ukurikije ibyihutirwa bitwawe nibipaki. Muri ubu buryo, uduce two mumodoka tugerarukira imbere dushobora kugeraho igihombo cya zeru. Gukemura neza ikibazo cyipaki cyipaki cya APM kugenzura na serivisi idasanzwe ya serivisi ya Bypass Serivisi ishinzwe.
Igisubizo 2 - GB-Urwego Kwagura sisitemu ya cache + gahunda yo gushushanya traffic
Sisitemu yo muri GB yaguye cache
Iyo igikoresho cyo kugura umutungo wacu ufite ubushobozi bwo gutunganya imikorere, birashobora gukingura umwanya runaka wububiko (impfizi) yigikoresho nka gace yisi yose yibikoresho, bitera imbaraga kubushobozi bwa buffer. Kubikoresho bimwe byo kunyurwa, byibuze ubushobozi bwa GB burashobora gutangwa nkumunyamaka wo kugura ibikoresho. Iri koranabuhanga rituma ubushobozi bwa buffer bwo kugura umutungo wacu ibikoresho inshuro magana hejuru kurenza iy'ibikoresho bisanzwe. Muburyo bumwe bwo kohereza, micro ntarengwa yatuje igihe cyo kugura umutungo wacu ukimara kuba kirekire. Urwego rwa Millisecond rushyigikiwe n'ibikoresho by'ukubona gakondo byazamuwe ku rwego rwa kabiri, kandi igihe cya Micro-cant kirashobora gutwarwa niyongereyeho inshuro ibihumbi.
Ubushobozi bwamato rusange
Ikoranabuhanga ritunganya Ikoranabuhanga - Igisubizo gishingiye kuri CAFER nini ya buffer +
Hamwe nubushobozi bunini-buffer buffer, amakuru yumuhanda yatunganijwe na micro-burst yaturika, kandi ikoranabuhanga rishingiye ku muhanda rikoreshwa mubyerekeranye no kugera hanze kugirango tugere kubisohoka neza kubikoresho byo gusesengura. Binyuze mu ishyirwa mu bikorwa ry'ikoranabuhanga, ibintu by'ipaki bya paki byatewe na micro-birst bikemuwe.
