Mubisanzwe NPB isaba ibintu, ikibazo kibangamira abayobozi ni igihombo cyatewe no guhuzagurika kwipaki yindorerwamo hamwe numuyoboro wa NPB.Gutakaza paki muri NPB birashobora gutera ibimenyetso bikurikira mubikoresho byo gusesengura inyuma:
- Impuruza itangwa mugihe igipimo cyo kugenzura imikorere ya serivisi ya APM kigabanutse, kandi igipimo cyo gutsinda cyaragabanutse
- Umuyoboro wa NPM ukurikirana ibipimo byerekana ibimenyetso bidasanzwe
- Sisitemu yo gukurikirana umutekano yananiwe kumenya ibitero byurusobe kubera gusiba ibyabaye
- Gutakaza ibikorwa byimyitwarire ya serivisi byakozwe na sisitemu yo kugenzura serivisi
... ...
Nka sisitemu yo gufata no gukwirakwiza uburyo bwo gukurikirana Bypass, akamaro ka NPB irigaragaza.Muri icyo gihe, uburyo butunganya amakuru yamapaki yimodoka aratandukanye cyane na gakondo ya enterineti isanzwe, kandi tekinoroji yo kugenzura ibinyabiziga byumuvuduko wibikorwa byinshi bya serivise ntabwo ikoreshwa kuri NPB.Nigute wakemura igihombo cya NPB, reka duhere kumpamvu yo gusesengura igihombo cya paki kugirango tuyibone!
NPB / TAP Ipaki Yatakaye Guterana Imizi Impamvu Isesengura
Mbere ya byose, dusesenguye inzira nyabagendwa nyayo hamwe no gushushanya amakarita hagati ya sisitemu nu kwinjira no gusohoka kurwego rwa 1 cyangwa urwego rwa NPB.Ntakibazo cyubwoko bwa netologiya topologiya NPB ikora, nka sisitemu yo gukusanya, hariho byinshi-kuri-byinshi byinjira mumodoka hamwe nibisohoka hagati ya "kwinjira" na "ibisohoka" bya sisitemu yose.
Noneho turareba imiterere yubucuruzi ya NPB duhereye kuri chip ya ASIC ku gikoresho kimwe:
Ikiranga 1.Mubisanzwe byinshi-kuri-umwe cyangwa byinshi-kuri-byinshi byo guhuza ibinyabiziga, igipimo cyumubiri cyibisohoka mubisanzwe ni gito ugereranije nigipimo rusange cyumubiri winjiza.Kurugero, imiyoboro 10 yo gukusanya 10G numuyoboro 1 wibisohoka 10G;Muburyo bwo kohereza ibintu byinshi, NPBBS yose irashobora kurebwa muri rusange.
Ikiranga 2: ASIC chip cache umutungo ni muto cyane.Ukurikije chip isanzwe ikoreshwa muri ASIC, chip ifite ubushobozi bwo guhana 640Gbps ifite cache ya 3-10Mbytes;Ubushobozi bwa 3.2Tbps chip ifite cache ya 20-50 mbytes.Harimo BroadCom, Barefoot, CTC, Marvell nabandi bakora ibicuruzwa bya ASIC.
Ikiranga 3: Uburyo busanzwe bwo kurangiza-kurangiza PFC uburyo bwo kugenzura ntabwo bukoreshwa kuri serivisi za NPB.Intandaro yuburyo bwo kugenzura imigendekere ya PFC nugushikira ibitekerezo byanyuma byo guhagarika umuhanda, kandi amaherezo ukagabanya kohereza paki kuri protocole yibice byitumanaho kugirango bigabanye ubukana.Nyamara, paki yinkomoko ya serivise ya NPB ni indorerwamo zuzuye, kuburyo ingamba zo gutunganya ibibazo zishobora gutabwa gusa cyangwa kubikwa.
Ibikurikira nuburyo bugaragara bwa micro-guturika kumurongo ugenda:
Dufashe interineti ya 10G nkurugero, murwego rwa kabiri igishushanyo mbonera cyisesengura ryumuhanda, igipimo cyumuhanda gikomeza kuri 3Gbps mugihe kirekire.Ku mbonerahamwe yerekana isesengura rya micro milisegonda, umuvuduko wimodoka (MicroBurst) warenze cyane igipimo cyumubiri cya 10G.
Ubuhanga bwingenzi bwo kugabanya Microburst ya NPB
Mugabanye ingaruka za asimmetric physique interfeque idahuye- Mugihe utegura umuyoboro, gabanya ibyinjijwe bitagabanijwe kandi usohore igipimo cyimibiri igaragara bishoboka.Uburyo busanzwe nugukoresha igipimo cyo hejuru hejuru ya interineti ihuza, kandi ukirinda igipimo cyimiterere idasanzwe (urugero, gukopera 1 Gbit / s na traffic 10 Gbit / s icyarimwe).
Hindura neza politiki yo gucunga cache ya serivisi ya NPB- Politiki isanzwe yo gucunga cache ikoreshwa kuri serivisi yo guhinduranya ntabwo ikoreshwa kuri serivisi yohereza serivisi ya NPB.Politiki yo gucunga cache yubwishingizi buhamye + Gusangira imbaraga bigomba gushyirwa mubikorwa hashingiwe kubiranga serivisi ya NPB.Kugirango ugabanye ingaruka za microburst ya NPB munsi yibikoresho bya chip bigezweho.
Shyira mubikorwa gucunga ibinyabiziga byashyizwe mubikorwa- Shyira mubikorwa imiyoborere yambere yimodoka yubuyobozi bushingiye kumurongo.Menya neza serivisi nziza yumurongo wibanze ushingiye kumurongo wumurongo wumurongo, kandi urebe ko abakoresha serivise yimodoka yimodoka ishobora koherezwa nta gutakaza paki.
Igisubizo cyumvikana cya sisitemu cyongera ubushobozi bwo gupakira hamwe nubushobozi bwo gukora traffic- Guhuza igisubizo binyuze muburyo bwa tekiniki bwo kwagura ubushobozi bwo gupakira ubushobozi bwa chip ya ASIC.Muguhindura imigezi ahantu hatandukanye, micro-guturika ihinduka micro-unifike yo gutembera nyuma yo gushiraho.

Microburst Gutunganya Ikoranabuhanga - Ubuyobozi bushingiye kubikorwa byihutirwa
Iyo igice cyo gufata ibinyabiziga cyoherejwe mu bwigenge, gishobora kandi gushyirwa imbere ukurikije akamaro k'igikoresho cyo gusesengura inyuma cyangwa akamaro k'amakuru ya serivisi ubwayo.Kurugero, mubikoresho byinshi byo gusesengura, APM / BPC ifite umwanya wambere kuruta gusesengura umutekano / ibikoresho byo kugenzura umutekano kuko bikubiyemo gukurikirana no gusesengura amakuru atandukanye yerekana sisitemu zingenzi zubucuruzi.Kubwibyo, kuri iki kintu, amakuru asabwa na APM / BPC arashobora gusobanurwa nkibyingenzi byambere, amakuru asabwa nibikoresho byo kugenzura umutekano / ibikoresho byo gusesengura umutekano birashobora gusobanurwa nkibintu byihutirwa, kandi amakuru asabwa nibindi bikoresho byisesengura arashobora gusobanurwa nkibiri hasi icyambere.Iyo ibyegeranijwe byegeranijwe byinjiye mu cyambu, ibyingenzi bisobanurwa ukurikije akamaro k'ibipaki.Amapaki yibyingenzi byihutirwa byoherezwa nyuma yamapaki yibyingenzi byoherejwe imbere, naho udupaki twibindi byihutirwa byoherezwa nyuma yamapaki yibyingenzi byoherejwe.Niba udupaki twibanze twibanze dukomeje kuhagera, udupaki twibanze twibanze twoherejwe.Niba ibyinjijwe byarenze ubushobozi bwo kohereza ibyambu bisohoka mugihe kirekire, amakuru arenze abikwa muri cache yigikoresho.Niba cache yuzuye, igikoresho gikunda guta paki zurutonde rwo hasi.Ubu buryo bwambere bwo kuyobora buteganya ko ibikoresho byingenzi byo gusesengura bishobora kubona neza amakuru yumwimerere asabwa kugirango asesengurwe mugihe nyacyo.
Microburst Gutunganya Ikoranabuhanga - uburyo bwo kwemeza ibyiciro byose bya serivise nziza
Nkuko bigaragara ku gishushanyo cyavuzwe haruguru, tekinoroji yo gutondekanya ibinyabiziga ikoreshwa mu gutandukanya serivisi zitandukanye ku bikoresho byose ku cyerekezo cyinjira, kwegeranya / intangiriro, hamwe n’ibisohoka, kandi ibyihutirwa by’ibipapuro byafashwe byongeye gushyirwaho ikimenyetso.Umugenzuzi wa SDN atanga politiki yibanze yumuhanda muburyo bukomatanyije kandi ayikoresha kubikoresho byohereza.Ibikoresho byose bitabira imiyoboro byashizwe kumurongo utandukanye ukurikije ibyihutirwa bitwarwa nudupaki.Muri ubu buryo, uduce-twinshi twambere twambere paki zishobora kugera kubutaka bwa zeru.Gukemura neza ikibazo cyo gutakaza paki yo kugenzura APM no kugenzura serivisi zidasanzwe bypass serivisi zumuhanda.
Igisubizo 2 - Gahunda yo Kwagura Urwego rwa GB Cache + Gahunda yo Gushiraho Imodoka
Urwego rwa GB Urwego rwagutse Cache
Iyo igikoresho cyikigo cyacu cyo kugura ibinyabiziga gifite ubushobozi bwambere bwo gutunganya imikorere, kirashobora gufungura umwanya munini mububiko (RAM) bwigikoresho nka Buffer yisi yose yibikoresho, bitezimbere cyane ubushobozi bwa Buffer bwibikoresho.Kubikoresho bimwe byo kugura, byibuze ubushobozi bwa GB burashobora gutangwa nkumwanya wa cache wibikoresho byo kugura.Iri koranabuhanga rituma ubushobozi bwa Buffer bwibikoresho byacu byo kugura ibinyabiziga byikubye inshuro amagana kurenza ibikoresho bisanzwe byo kugura.Mugipimo kimwe cyo kohereza, micro ntarengwa yaturika mugihe cyibikoresho byacu byo kugura ibinyabiziga biba birebire.Urwego rwa milisegonda rushyigikiwe nibikoresho gakondo byo kugura rwazamuwe kurwego rwa kabiri, kandi igihe gito gishobora guterwa cyongerewe inshuro ibihumbi.
Ubushobozi bwo gushiraho ibinyabiziga byinshi
Microburst Itunganya Ikoranabuhanga - igisubizo gishingiye kuri Buffer Caking nini + Shaping traffic
Hamwe nubushobozi buhebuje bwa Buffer, amakuru yumuhanda yatewe na micro-guturika arafatwa, kandi tekinoroji yo gushiraho ibinyabiziga ikoreshwa mumigendere isohoka kugirango igere ku musaruro mwiza wapaki kubikoresho byo gusesengura.Binyuze mu ikoreshwa ryikoranabuhanga, ibintu byo gutakaza paki biterwa na micro-guturika byakemuwe muburyo bukomeye.
