Emhlabeni wezobuchwepheshe wenethiwekhi, ukuqonda indima nokubaluleka kokuthopha kwenethiwekhi, ama-microbursts, i-Tap switch kanye nabathengisi bepakethi yenethiwekhi kubuchwepheshe be-microbursts kubalulekile ekuqinisekiseni ingqalasizinda yokuxhumana engenamthungo nesebenzayo. Le blog izohlola imiqondo esemqoka nobuchwepheshe obandakanyeka kumompompi wenethiwekhi, ama-microbursts, thinta switch kanye nabathengi bepakethi yenethiwekhi kubuchwepheshe be-microbursts.
Ompompi wenethiwekhiamadivaysi asetshenziswa kunethiwekhi ukuqapha nokubamba ithrafikhi yenethiwekhi. Zisetshenziselwa ukubheka kalula amasiginali ngaphandle kokuphazamisa ukusebenza kwenethiwekhi. Ompompi benethiwekhi benzelwe ukuvumela onjiniyela nabaphathi ukuba bathwebule futhi bahlaziye ithrafikhi yenethiwekhi ngesikhathi sangempela. Bangamathuluzi abalulekile ekuxazululeni ukuxazulula inkinga nokubheka ukusebenza kwenethiwekhi. Ompompi wenethiwekhi babalulekile ekuthwebizeni nokubheka ithrafikhi yenethiwekhi ngesikhathi sangempela. Banikeza onjiniyela nabaphathi abakwazi ukukhomba nezinkinga zokuxazulula izinkinga, baqaphe ukusebenza kwenethiwekhi, futhi baqinisekise ukuphepha kwenethiwekhi. Ngokuthwebula ithrafikhi yenethiwekhi ezindaweni ezibalulekile kunethiwekhi, ompompi wenethiwekhi bahlinzeka ngokuqonda okubalulekile ekusebenzeni kwenethiwekhi nokuziphatha.
* Ukuqapha kwethrafikhi okunembile: Ama-Network Tps Capture futhi ulethe yonke ithrafikhi yenethiwekhi, kufaka phakathi ama-microbursts, kumathuluzi okubheka. Lokhu kuqinisekisa ukuthi awekho amaphakethe aphuthelwe noma aphonswe, avumela ukuhlaziya okunembile nokuxazulula inkinga.
* Ukubonakala kwesikhathi sangempela: Ompompi bahlinzeka ngokubonakala kwangempela ekusebenzeni kwenethiwekhi, okuvumela abaphathi benethiwekhi ukuthola nokuhlaziya ama-microbursts njengoba kwenzeka. Lokhu kwenza ukukhonjwa okusheshayo nokuncishiswa kwezinkinga.
* Ukuqapha okungathandeki: Ompompi basebenza kalula, okusho ukuthi abangenisi okwengeziwe we-latency noma bathinte ukusebenza kwenethiwekhi. Lokhu kubalulekile ngesikhathi se-microbursts, njengoba kukuphi ukubambezeleka okwengeziwe noma ukugcwala okubangelwa amathuluzi okuqapha kungandisa inkinga.
Abathengisi be-Network Packet, ngakolunye uhlangothi, amadivayisi asetshenziselwa ukuphatha kahle futhi asabalalise ithrafikhi kuyo yonke inethiwekhi. Zenzelwe ukwandisa ukusebenza kwenethiwekhi ngokuhlanganisa, ukuhlunga, nokusabalalisa ithrafikhi yenethiwekhi kumathuluzi afanele okuqapha kanye nokuphepha. Abathengisi be-Network Packet babalulekile ekuqinisekiseni ukuthi ithrafikhi yenethiwekhi iphethwe kahle futhi iqondiswe kumathuluzi afanele okuhlaziya nokuqapha. Abathengisi be-Network Packet badlala indima ebalulekile ekuphatheni kahle nasekusakazeni ithrafikhi yenethiwekhi. Ngokuhlanganisa, ukuhlunga, nokusabalalisa ithrafikhi yenethiwekhi kumathuluzi afanele okuqapha kanye nokuphepha, i-Network Packet Broker ithuthukisa ukusebenza kahle kwenethiwekhi futhi iqinisekise ukuthi ithrafikhi yenethiwekhi iphethwe kahle futhi iqondiswe kumathuluzi afanele okuhlaziya nokuqapha.
* Ukulayisha umthwalo: I-NPBS ingasabalalisa ithrafikhi engenayo ngokulinganayo kuwo wonke amathuluzi amaningi okuqapha, ukuvimbela ukulayisha ngokweqile kanye nokuqinisekisa ukucubungula okusebenzayo ngesikhathi se-microbursts.
* Ukuhlunga kwephakethe kanye nokuhlangene: I-NPBS ingahlunga amaphakethe angafanele, idatha ehlanganisiwe kusuka ezixhumanisi eziningi, kanye ne-strip ye-protocol engadingekile. Lokhu kunciphisa inani ledatha elithunyelwe kumathuluzi okuqapha, ukuthuthukisa ukusebenza kwawo ekuhlaziyeni ama-microbursts.
* Ukuphindaphinda kwethrafikhi: I-NPBS ingaphinda futhi idlulise ukusakazwa okuthize kwethrafikhi kumathuluzi amaningi okuqapha ngasikhathi sinye. Lokhu kuvumela ukuhlaziya okufanayo futhi kuthuthukisa amathuba okuthola nokunciphisa ama-microbursts ngokushesha.
* Ukuqondisa kwethrafikhi ehlakaniphile: I-NPPS ethuthukisiwe ingenza ukuhlola okujulile kwepakethe kanye nokuqondisa kwethrafikhi okusekelwe kwimibandela ethile. Bangakwazi ukuqondisa ithrafikhi efanelekile kumathuluzi okuhlaziya afanele, aqinisekise ukuqapha okuhlosiwe kwama-microbursts.
Thepha ShintshaIngabe amadivaysi enethiwekhi asetshenziselwa ukuxhuma ompompi wenethiwekhi namanye amathuluzi okuqapha kwinethiwekhi. Zenzelwe ukuhlinzeka ngephuzu eliphakathi lokuxhuma nokuphatha ompompi wenethiwekhi, abathengi bepakethi yenethiwekhi, namanye amathuluzi okuqapha. Thepha Shintsha badlala indima ebalulekile ekuqinisekiseni ukuthi ithrafikhi yenethiwekhi ibhekelwe kahle futhi ibhekelwe ngempumelelo futhi ihlaziywe. I-Tap switch inikezela ngephuzu eliphakathi lokuxhuma nokuphatha ompompi wenethiwekhi, abathengisi bepakethi yenethiwekhi, namanye amathuluzi wokuhlola. Ngokuhlinzeka ngephuzu eliphakathi lokuphatha amathuluzi okuqapha inethiwekhi, ukushintshwa kompompi kudlala indima ebalulekile ekuqinisekiseni ukuthi ithrafikhi yenethiwekhi ibhekelwe kahle futhi ihlelwe ngempumelelo futhi ihlaziywe.
Yini #micRoburst?
I-Port ye-Recorktap Shintrap ithola ukuqhuma kwemininingwane ephakeme kaningi kunezinga elijwayelekile kungakapheli isikhathi esifushane (imvamisa ngaphakathi kwe-1-100 ms), futhi idlula ngisho ne-bandwidth yokuhambisa ethekwini ngephuzu elithile ngesikhathi, ukwenza ukulahleka kwephakethe kwedatha ethile. Uma ithrafikhi ye-micro-burst esheshayo idlula isikhala se-#tapwitch cache, idatha eyeqile ingalahlwa kuphela, okuholela ekulahlekelweni kwephakethe.
I-Microbursts yimithombo esheshayo yedatha engalayisha ngokweqile inethiwekhi futhi ibangele izindaba zokusebenza. Zenzeka lapho idivaysi yenethiwekhi, efana nokushintsha noma i-router, ithola ukuqhuma kwethrafikhi edlula umthamo wayo wokudlulisa. I-Microbursts ingaholela ekulahlekelweni kwephakethe, i-jitter, kanye nokwanda kwe-latency, okungathinta kabi ukusebenza kwenethiwekhi kanye nesipiliyoni somsebenzisi. I-Microbursts iyimbangela evamile yezinkinga zokusebenza kwenethiwekhi. Ngokulayisha ngokweqile amadivaysi enethiwekhi aneziqhumane ezisheshayo zedatha, ama-microbursts angaholela ekulahlekelweni kwephakethe, i-jitter, kanye nokwanda kwe-latency. Amandla okubheka nokuhlaziya ama-microbursts kubalulekile ekwakheni ukusebenza kwenethiwekhi kanye nokuqinisekisa ukusebenza kwenethiwekhi okubushelelezi nokusebenzayo.
Ukuhlanganiswa kompompi wenethiwekhi, abathengisi be-Network Packet, kanye nokuthepha okushintshiwe kokushaywa kwe-micro kudlala indima ebalulekile ekuqinisekiseni ukusebenza kwengqalasizinda yenethiwekhi. Ngokuqapha ngempumelelo nangokuhlaziya ithrafikhi yenethiwekhi, izinhlangano zingakhomba futhi zixazulule izinkinga zokusebenza, zisebenzise ukusebenza kwenethiwekhi, futhi ziqinisekise ukuphepha nobuqotho benethiwekhi yabo. Ompompi wenethiwekhi, ama-microbursts, thinta switch kanye nabathengisi be-Network Packet kubuchwepheshe be-Microbursts badlala indima ebalulekile ngokuqapha ngempumelelo nokuhlaziya izimoto zokuxhumana, futhi baqinisekise ukusebenza kwenethiwekhi, futhi baqinisekise ukuphepha kanye nobuqotho benethiwekhi yabo. Ukuqonda indima nokubaluleka kwalezi zingcweti kubalulekile ukuze ulondoloze ingqalasizinda yokuxhumana enempilo.
