Ukutshintsha Umthamo

Umthamo wokutshintsha utshintshi, owaziwa ngokuba yi-backplane bandwidth okanye ukutshintshwa kwe-bandwidth, yimali ephezulu yedatha enokuthi iphathwe phakathi kweprosesa ye-interface okanye i-interface yekhadi kunye nebhasi yedatha.Umthamo wokutshintshiselana ubonisa umthamo wotshintshiselwano lwedatha iyonke yokutshintsha, kwaye iyunithi yiGbps.Umthamo wotshintshiselwano wokutshintsha ngokubanzi ukusuka kwiiGbps ezininzi ukuya kumakhulu eGbps.Ukuphakama kwamandla okutshintsha kokutshintsha, kunamandla amandla okucubungula idatha, kodwa indleko yokuyila iphezulu.

 Ireyithi yokugqithisela ipakethi

Ireyithi yokuthumela ipakethe yokutshintsha ibonisa ubungakanani bokukwazi ukutshintshela ukuhambisa iipakethi.Iyunithi ngokubanzi yibps, kwaye umyinge wogqithiso lwepakethi yotshintshiselwano ngokubanzi lusuka kumashumi e Kpps ukuya kumakhulu eMPps.Izinga lokuthunyelwa kwepakethe libhekisela kwinani leepakethi zedatha yezigidi (Mpps) umtshintshi unokuhamba phambili ngesekhondi, oko kukuthi, inani leepakethi zedatha ezinokuthi zigqithise phambili ngexesha elifanayo.Izinga lokuthunyelwa kwepakethi libonisa amandla okutshintsha kokutshintsha kwiiyunithi zeepakethi zedatha.

Enyanisweni, isalathisi esibalulekileyo esimisela izinga lokuthunyelwa kwepakethi yi-backplane bandwidth yokutshintsha.Ukuphakama kwe-backplane bandwidth yokutshintsha, amandla okusebenza okuqhubela phambili idatha, oko kukuthi, ukuphakama kwepakethi yokuthumela isantya.

Ethernet Ring

Iringi ye-Ethernet (eyaziwa ngokuba yinethiwekhi yomsesane) yi-topology yeringi equka iqela le-IEEE 802.1 ehambelanayo ye-Ethernet nodes, i-node nganye enxibelelana namanye ama-nodes amabini ngokusebenzisa i-802.3 Media Access Control (MAC) esekelwe kwi-ring port I-Ethernet MAC inakho. zithwalwe zezinye iitekhnoloji zomaleko wenkonzo (ezifana ne-SDHVC, i-Ethernet pseudowire ye-MPLS, njl. njl.), kwaye zonke ii-nodes zinokunxibelelana ngokuthe ngqo okanye ngokungathanga ngqo.
