I-Exchange yitemu elivamile lobuchwepheshe obuthumela ulwazi ukuze ludluliselwe emzileni ohambisanayo ohlangabezana nezimfuneko ngemishini eyenziwa ngesandla noma ezenzakalelayo ngokuvumelana nezidingo zokudlulisa ulwazi kuzo zombili iziphetho zokuxhumana.Ngokwezikhundla ezihlukene zokusebenza, ingahlukaniswa ngokushintsha kwenethiwekhi yendawo ebanzi kanye nokushintsha kwenethiwekhi yendawo.Ukushintshwa kwenethiwekhi yendawo ebanzi kuwuhlobo lwemishini eqeda umsebenzi wokushintshana ngolwazi ohlelweni lokuxhumana.Ngakho-ke, yiziphi izindlela zokudlulisela iswishi?

Indlela yokudlulisela:

1. Sika-ngokusebenzisa ukushintsha
2. Ukushintsha kwesitolo nokudlulisa
3. Ukushintsha okungenaziqephu

Ukuthi ukudlulisa okuqondile noma ukudlulisela phambili isitolo kuyindlela yokudlulisela izendlalelo ezimbili, futhi amasu awo okudlulisela phambili asekelwe endaweni okuyiwa kuyo i-MAC (DMAC), awukho umehluko phakathi kwezindlela ezimbili zokudlulisela phambili kuleli phuzu.
Umehluko omkhulu phakathi kwazo yilapho zibhekana nokudlulisela phambili, okungukuthi, ukuthi iswishi ibhekana kanjani nobudlelwano phakathi kwenqubo yokwamukela kanye nenqubo yokudlulisela phambili iphakethe ledatha.

Uhlobo lokudlulisela:
1. Sika
Iswishi ye-Ethernet eqondile ingaqondwa njengeswishi yocingo ye-matrix ewela iqonde phezulu naphakathi kwembobo ngayinye.Lapho ithola iphakethe ledatha endaweni yokufaka, ihlola unhlokweni wephakethe, ithola ikheli lendawo yephakethe, iqala ithebula lokubheka eliguquguqukayo langaphakathi futhi iliguqulele embobeni yokukhiphayo ehambisanayo, ixhume ezimpambanweni zokufakwayo. nokukhiphayo, futhi idlulisela iphakethe ledatha ngqo Imbobo ehambisanayo ibona umsebenzi wokushintsha.Njengoba kungekho sitoreji esidingekayo, ukubambezeleka kuncane kakhulu futhi ukushintshaniswa kuyashesha kakhulu, okuyinzuzo yakho.
Ububi bayo ukuthi ngenxa yokuthi okuqukethwe kwephakethe ledatha akulondolozwanga ngokushintsha kwe-Ethernet, ayikwazi ukuhlola ukuthi iphakethe ledatha elidlulisiwe alilungile yini, futhi alikwazi ukuhlinzeka ngamakhono okuthola iphutha.Ngenxa yokuthi asikho isilondolozi, izimbobo zokufaka/zokukhiphayo ezinesivinini esihlukile azikwazi ukuxhunywa ngokuqondile, futhi amaphakethe alahleka kalula.

2. Gcina bese udlulisela phambili (Isitolo; Dlulisa)
Indlela yesitolo-nokudlulisela iyindlela esetshenziswa kakhulu emkhakheni wamanethiwekhi amakhompyutha.Ihlola iphakethe ledatha yembobo yokufaka, ikhiphe ikheli lendawo yephakethe ledatha ngemva kokucubungula iphakethe lephutha, futhi iliguqulele endaweni yokukhipha ukuze ithumele iphakethe ngetafula lokubheka.Ngenxa yalokhu, indlela yokulondoloza nokudlulisela phambili inokulibaziseka okukhulu ekucutshungulweni kwedatha, okuwukushiyeka kwayo, kodwa ingenza ukutholwa kwephutha kumaphakethe wedatha afaka iswishi futhi ithuthukise ngempumelelo ukusebenza kwenethiwekhi.Kubaluleke kakhulu ukuthi ikwazi ukusekela ukuguqulwa phakathi kwamachweba wesivinini esihlukile futhi igcine ukubambisana phakathi kwamachweba anesivinini esikhulu namachweba anesivinini esiphansi.

3. I-fragment Free
Lesi yisixazululo phakathi kokubili kokuqala.Ihlola ukuthi ubude bephakethe ledatha banele ngamabhayithi angu-64, uma bungaphansi kwamabhayithi angu-64, kusho ukuthi iphakethe lomgunyathi, bese ulahla iphakethe;uma likhulu kunamabhayithi angama-64, thumela iphakethe.Le ndlela futhi ayinikezi ukuqinisekiswa kwedatha.Isivinini sayo sokucubungula idatha siyashesha ukwedlula isitolo-nokudlulisela phambili, kodwa sihamba kancane kunokudlula okuqondile.
Kungakhathaliseki ukuthi ukudlulisela okuqondile noma ukudlulisela phambili kwesitolo, kuyindlela yokudlulisela izendlalelo ezimbili, futhi amasu azo okudlulisela phambili asekelwe endaweni okuyiwa kuyo i-MAC (DMAC).Awukho umehluko phakathi kwezindlela ezimbili zokudlulisela phambili kuleli phuzu.Umehluko omkhulu phakathi kwazo yilapho zibhekana nokudlulisela phambili, okungukuthi, ukuthi iswishi ibhekana kanjani nobudlelwano phakathi kwenqubo yokwamukela kanye nenqubo yokudlulisela phambili iphakethe ledatha.
