Sechinhu chakakosha kutaurirana data chigadzirwa,maindasitiri Ethernet switchinofanirwa kuve yakavhurika uye inoenderana nezvigadzirwa kubva kune akawanda vagadziri kuti ive nechokwadi chenguva refu yakagadzikana uye yakachengeteka kushanda kwehurongwa.Kana iwe uchingovimba nemumwe mugadziri, njodzi yakakura zvakanyanya.Naizvozvo, zvichibva pane scalability uye kuenderana kufunga, kutarisisa kwakazara kunofanirwa kupihwa kusanganisamaindasitiri Ethernet switchkubva kune vakasiyana vagadziri kuti vagadzire isina mhete network yekuisa hwaro hwakasimba hwekuwedzera network mune ramangwana.Saka, maindasitiri eEthernet anochinja kubva kune vakasiyana vagadziri vanogona kuvaka aredundant ring network?

Mhinduro ndihongu.Industrial Ethernet switch kubva kune vakasiyana vagadziri vanogona kutaurirana mumwe nemumwe kuburikidza ne loop yemagetsi port uye optical port.

⑴ Networking protocol

Zviyero zvinoenderana nenyika, zviyero zvemabhizinesi eGuodian, uye zviyero zveindasitiri zviri kugadzirwa zvese zvinonyatso taura kuti "network inogona kuumbwa zvinoenderana nezvinodiwa neiyo simba system, uye networking protocol inofanirwa kutora zvirevo zvepasi rose:RSTP, MSTP, nezvimwewo.”Naizvozvo, pamusoro pekutsigira yakavanzika Mhete protocol ine yakazvimirira yehungwaru kodzero dzakagadzirwa nemugadziri wega wega, iyo indasitiri yeEthernet switch inofanirwawo kutsigira RSTP neMSTP yepasi rose standard ring network protocol.Chero bedzi iyo RSTP neMSTP yepasi rose standard ring network maprotocol akagamuchirwa, maindasitiri eEthernet switch kubva kune vakasiyana vagadziri anogona kugadzira network ine topological zvimiro senyeredzi, mhete, uye muti.

⑵ layer yemuviri

Iko hakuna dambudziko mukubatana uye kupindirana kwekuchinja kubva kune vakasiyana vanogadzira padanho remuviri, chero bedzi midhiya paramita ichienderana, senge iyo indasitiri-giredhi optical fiber transceiver iri single-mode kana akawanda-mode, uye wavelength. parameters ye optical fiber transceiver.Kupfupisa, zvisinei neiyo networking protocol kana iyo yemuviri layer, switch kubva kune vakasiyana vagadziri vanogona kutaurirana kana vachigadzira imwechete mhete network.
