Switching Capacity

Iko kuchinjika simba rekuchinja, inozivikanwawo seye backplane bandwidth kana switching bandwidth, ndiyo yakanyanya kuwanda yedata inogona kubatwa pakati peiyo switch interface processor kana interface kadhi uye data bhasi. Iyo yekutsinhana simba inoratidza huwandu hwese hwekuchinjana data kweiyo switch, uye iyo unit iGbps. Iyo yekutsinhana kwekuchinja kweiyo general switch inotangira kubva akati wandei kusvika kumazana eGbps. Iyo yakakwirira yekuchinjisa simba rekuchinja, kusimba kwekugona kugadzirisa data, asi kukwira kwemutengo wekugadzira.

 Packet kutumira Rate

Chiyero chekufambisa kwepaketi chekuchinja chinoratidza saizi yekugona kweiyo switch yekuendesa mberi mapaketi. Iyo unit inowanzoita bps, uye mwero wekutumira wepaketi yezvizhinji switch kubva pamakumi eKpps kusvika kumazana eMpps. Chiyero chekuendesa kwepaketi chinoreva kuti mangani emamiriyoni emapaketi edata (Mpps) switch inogona kumberi pasekondi, ndiko kuti, nhamba yemapakiti e data ayo switch inogona kumberi panguva imwe chete. Chiyero chekufambisa kwepaketi chinoratidza kugona kwekuchinja kwechinjo mumayuniti emapaketi edata.

Muchokwadi, chiratidzo chakakosha chinotaridza mwero wekutakura wepaketi ndeye backplane bandwidth yekuchinja. Iyo yakakwira iyo backplane bandwidth yekuchinja, iyo yakasimba kugona kugadzirisa data, ndiko kuti, iyo yakakwirira yepaketi yekufambisa mwero.

Ethernet Mhete

Mhete yeEthernet (inowanzozivikanwa seringi network) iring topology ine boka reIEEE 802.1 rinoenderana neEthernet node, node imwe neimwe ichitaurirana nemamwe manodhi maviri kuburikidza ne802.3 Media Access Control (MAC) yakavakirwa ring port Iyo Ethernet MAC inogona. kutakurwa nemamwe masevhisi matekinoroji (akadai seSDHVC, Ethernet pseudowire yeMPLS, nezvimwewo), uye node dzese dzinogona kutaurirana zvakananga kana zvisina kunanga.
