Nk'uburyo bwo gufata no gukwirakwiza amakuru mu buryo bwa Bypass, akamaro ka NPB karagaragara. Muri icyo gihe, uburyo itunganya amakuru mu buryo butandukanye cyane n'uburyo busanzwe bwo guhindura amakuru mu buryo bwa Live Network, kandi ikoranabuhanga ryo kugenzura urujya n'uruza rw'amakuru mu buryo bwa Live Networks nyinshi ntirikoreshwa kuri NPB. Uburyo bwo gukemura ikibazo cy'amakuru mu buryo bwa NPB, reka dutangire duhereye ku isesengura ry'impamvu nyamukuru y'igihombo cy'amakuru mu buryo bwa Packets kugira ngo tubone!
Isesengura ry'impamvu nyamukuru y'igabanuka ry'umubyimba mu ipaki ya NPB/TAP
Mbere na mbere, dusesengura inzira nyayo y'ibinyabiziga n'isano iri hagati ya sisitemu n'ibinjira n'ibisohoka by'umuyoboro wa NPB wo ku rwego rwa 1 cyangwa urwego rwa 1. Uko ubwoko bw'imiterere y'umuyoboro NPB iteye kose, nk'uburyo bwo gukusanya, hari isano hagati y'ibinjira n'ibisohoka by'umuyoboro hagati y'"uburyo bwo kwinjira" n'"ibisohoka" bya sisitemu yose.
Hanyuma turebera hamwe uburyo NPB ikora mu bijyanye n'udupira twa ASIC ku gikoresho kimwe:
Ikiranga cya 1: "Umuvuduko w'itumanaho" n' "umuvuduko w'itumanaho" by'ibyinjira n'ibisohoka ntabwo bingana, bigatuma umubare munini w'ibice bito bisohoka ari igisubizo kidasubirwaho. Mu bihe bisanzwe byo guteranya abantu benshi cyangwa benshi, umuvuduko w'itumanaho ukunze kuba muto ugereranije n'umuvuduko w'itumanaho ryose ry'ibyinjira. Urugero, imiyoboro 10 y'ikusanyirizo rya 10G n'umuyoboro 1 w'isohoka rya 10G; Mu gihe cyo gushyiraho ikoranabuhanga mu byiciro byinshi, NPBBS zose zishobora kubonwa muri rusange.
Ikiranga cya 2: Umutungo wa ASIC chip cache ni muto cyane. Ku bijyanye na chip ya ASIC ikoreshwa cyane ubu, chip ifite ubushobozi bwo guhinduranya bwa 640Gbps ifite cache ya 3-10Mbytes; chip ifite ubushobozi bwa 3.2Tbps ifite cache ya 20-50 mbytes. Harimo BroadCom, Barefoot, CTC, Marvell n'abandi bakora chips za ASIC.
Ikiranga cya 3: Uburyo busanzwe bwo kugenzura ubwiyongere bw'amazi ya PFC kuva ku mpera kugeza ku mpera ntibwakoreshwa kuri serivisi za NPB. Intego nyamukuru y'uburyo bwo kugenzura ubwiyongere bw'amazi ya PFC ni ukugera ku buryo bwo gukumira ubwiyongere bw'amazi, no kugabanya kohereza amapaki kuri protocole stack y'aho itumanaho rikorera kugira ngo bigabanye ubwiyongere bw'amazi. Ariko, aho serivisi za NPB zituruka ni amapaki agaragara nk'aho ariho, bityo ingamba zo gutunganya ubwiyongere bw'amazi zishobora gutabwa cyangwa gushyirwa mu bubiko gusa.
Ibi bikurikira ni uko isura ya micro-burst isanzwe ku murongo w'amazi inyuramo igaragara:
Dufashe urugero rwa interface ya 10G, mu gishushanyo mbonera cy’urwego rwa kabiri cy’isesengura ry’imigendere y’urujya n’uruza rw’abantu, igipimo cy’urujya n’uruza rw’abantu kiguma kuri 3Gbps igihe kirekire. Ku mbonerahamwe y’isesengura ry’imigendere ya mikorosegonda, ukwiyongera kw’urujya n’uruza rw’abantu (MicroBurst) kwarenze cyane igipimo nyacyo cy’urujya n’uruza rw’abantu rwa 10G.
Uburyo bw'ingenzi bwo kugabanya ubushyuhe bwa NPB
Gabanya ingaruka zo kudahuza neza kw'isura y'umubiri- Mu gihe ushushanya umuyoboro, gabanya igipimo cy’imikorere y’injira n’isohoka ry’amakuru uko bishoboka kose. Uburyo busanzwe ni ugukoresha umuyoboro w’ihuza ry’amakuru ukoresheje ikoranabuhanga rigezweho, kandi ukirinda igipimo cy’imikorere y’ihuza ry’amakuru ukoresheje ikoranabuhanga ritajyanye n’igihe (urugero, gukoporora 1 Gbit/s na 10 Gbit/s icyarimwe).
Kunoza politiki yo gucunga cache ya serivisi ya NPB- Politiki isanzwe yo gucunga cache ikoreshwa kuri serivisi yo guhindura ntabwo ikoreshwa kuri serivisi yo kohereza amakuru ya NPB. Politiki yo gucunga cache ya garantie idahindagurika + gusharanganya ibintu mu buryo budasanzwe igomba gushyirwa mu bikorwa hashingiwe ku miterere ya serivisi ya NPB. Kugira ngo tugabanye ingaruka za microburst ya NPB hakurikijwe imbogamizi iriho muri iki gihe ku bikoresho bya chip.
