Anetwork switchchishandiso chinowedzera network uye chinogona kupa mamwe madoko ekubatanidza mune sub-network yekubatanidza mamwe makomputa.Iine maitiro ehupamhi hwekuita-mutengo wechiyero, kuchinjika kwakanyanya, kuri nyore, uye nyore kuita.Saka, ndeipi basa reiyo network switch mu data center?

Kana iyo network switch interface inogamuchira yakawanda traffic kupfuura yainogona kubata, network switch inosarudza kuichengeta kana network switch kuti iirase.Iyo cache yetiweki switch inowanzo kukonzerwa neyakasiyana network interface kumhanya, traffic yetiweki switch inongoerekana yaputika kana akawanda-kune-imwe traffic traffic.

Dambudziko rinowanzoitika rinokonzeresa kubhuroka munetiweki switch ndeyekuchinja kamwe kamwe muzhinji-kune-imwe traffic.Semuenzaniso, application inovakwa pane akawanda server cluster node.Kana imwe yemanodhi panguva imwe chete ichikumbira data kubva kunetiweki switch yemamwe manode ese, mhinduro dzese dzinofanira kusvika pa network switch panguva imwe chete.Kana izvi zvikaitika, mafashama emutraffic eese ma switch etiweki anozadza chiteshi cheanokumbira network switch.Kana iyo network switch isina kukwana egress buffers, network switch inogona kurasa imwe traffic, kana network switch inogona kuwedzera kunonoka application.Yakakwana buffers yetiweki switch inogona kudzivirira kurasikirwa kwepaketi kana kunonoka kwetiweki kunokonzerwa neakaderera-level protocol.

Iyo yazvino data center switching platform inogadzirisa dambudziko iri nekugovana switching buffer ye network switch.Iyo network switch ine buffer dziva nzvimbo yakagoverwa kune chaiyo chiteshi.Iwo akagovaniswa mabuffers etiweki switch anosiyana zvakanyanya pakati pevatengesi vakasiyana uye mapuratifomu.

Vamwe vanogadzira network switch vanotengesa network switch dzakagadzirirwa nzvimbo dzakati.Semuenzaniso, mamwe maswiti etiweki ane yakakura buffer processing, iyo inokodzera akawanda-kune-imwe ekufambisa mamiriro munzvimbo yeHadoop.Munzvimbo inokwanisa kugovera traffic, network switch haidi kuendesa mabuffers padanho rekuchinja.

Iyo buffer yetiweki switch yakakosha, asi hapana mhinduro chaiyo yekuti ingani nzvimbo yatinoda kune network switch.Iyo yakakura network switch buffer inoreva kuti network haizorasa chero traffic, uye zvakare zvinoreva kuti kunonoka kwetiweki kunowedzera-iyo data yakachengetwa netiweki switch inoda kumirira isati yaendeswa mberi.Vamwe vatariri venetiweki vanosarudza madiki mabhafa etiweki switch kuti abvumire application kana protocol kugadzirisa kudzikisa imwe traffic.Mhinduro chaiyo ndeyekunzwisisa nzira yetraffic yeiyo application's network switch uye sarudza network switch inoenderana nezvido izvi.
