Zvakananga-kuburikidza
Rakananga-kuburikidza neEthernet switches inogona kunzwisiswa semutsetse matrix ine crisercross mitsara pakati pemidziyo. Kana paketi yedata painoonekwa pachiteshi chekupinda, iyo Packet Heacer yakaongororwa, iyo kero yekuenda inowanikwa, tafura yemukati yekutsvaga inotangwa, uye chiteshi chinowirirana chakashandurwa. Iyo yedata packet yakabatana nekupindirana kweiyo yekuisa uye kubuda, uye packet yakabatana zvakananga kune iyo inoenderana muchiteshi chekuziva kuti switching basa. Nekuti hazvidi kuchengetwa, kunonoka kwakanyanya uye kuchinja kwakanyanya, ndiko kunobatsira. Iko kukanganisa ndeyekuti kubvira mukati meiyo yedata yedata isina kuponeswa neiyo Ethet switch, hazvigoneke kutarisa kana iyo inotapukira yedata yekukanda isina kunaka, uye kukanganisa kwekuona hakugone kupihwa. Nekuti hapana cache, iyo yekuisa / yekubuda madhiri ekumhanya kwakasiyana hakugone kubatana, uye zviri nyore kurasikirwa.
Chitoro uye mberi
Chitoro uye Mberi Mode ishandiso yekunyorera mumunda wekombiyuta network. Iyo yekutanga inochengetedza iyo packet yekupinda muchiteshi cheCRC, zvinoita crc Nekuda kweizvi, kunonoka kwekuchengetera uye kuendesa ku data kukura kwedata kwakakura, ndiko kupfupikisa kwaro, asi kunogona kuona zvisina kunaka macketi ekutenderera nekuvandudza switch uye zvakanyanya kuvandudza mashandiro emhando yepamusoro. Kunyanya kukosha ndechekuti inogona kutsigira kushandurwa pakati pezviteshi zvekumhanya kwakasiyana uye kuchengeta basa rekubatana pakati pezvidimbu zvepamusoro uye zvakadzika-mhanya-mhanya-madimikira.
Chidimbu Chekusazviparadzaniswa
Iyi ndiyo mhinduro pakati pevaviri vekutanga. Iyo inotarisa kuti kureba kweiyo yedata yedata yakakwana kune 64 mabheti. Kana iri isingasviki 64 mabheti, zvinoreva kuti ipaketi yekunyepa uye pakapaketi yakaraswa; Kana yakakura kupfuura makumi matanhatu neshanu, iyo packet inotumirwa. Iyi nzira haigovera kuongororwa kwedata. Yayo data yekugadzirisa inokurumidza kupfuura yekuchengetedza uye kutumira, asi zvishoma nezvishoma pane zvakananga kupfuudza. Kusvitsa kuchinjika kweiyo hirschman switch.
Panguva imwecheteyo, iyo hirschman switch inogona kuendesa data pakati pezvimoto zvakawanda. Chiteshi chimwe nechimwe chinogona kutorwa seyakazvimirira muviri wetiwedhi Paunotumira iyo data yekutumira iyo node d, node b inogona kutumira data kune node c panguva imwe chete, uye zvese zvine iyo yakazara bandwidth ye network uye ine yavo chaiyo yekubatana. Kana iyo 10Mbps ethernet switch inoshandiswa, iyo yakazara traffic ye switch yakaenzana ne2x10mbps = 20Mbps. Kana 10mbps yakagoverwa hub inoshandiswa, iyo yakazara traffic yeHUB haizopfuure 10Mbps.
Muchidimbu, iyoHirschman switchIcho chishandiso chetiweki chinogona kupedzisa basa rekugadzirisa uye kutumira mafirita mafuremu zvichibva pane mac kero yekuzivikanwa. Iyo hirschman switch inogona kudzidza mac kero uye chengetedza mune yemukati kero tafura, uye kusvika pakanangana nechinongedzo kuburikidza nekuchinjika kwechinguvana pakati peiyo yakatangira
