Okokuqala, sidinga ukucacisa umqondo: ukushintshwa kwesendlalelo sokufinyelela, ukushintshwa kwesendlalelo sokuhlanganisa, nokushintsha kwesendlalelo esiyinhloko akukona ukuhlukaniswa nezimfanelo zamaswishi, kodwa kuhlukaniswa ngemisebenzi abayenzayo. Azinazo izidingo ezimisiwe, futhi zincike kakhulu kusayizi wendawo yenethiwekhi, amandla okudlulisela phambili idivayisi, kanye nendawo esakhiweni senethiwekhi. Isibonelo, iswishi efanayo Yesendlalelo 2 ingasetshenziswa kusendlalelo sokufinyelela noma isendlalelo sokuhlanganisa ezakhiweni ezihlukene zenethiwekhi. Uma isetshenziswa isendlalelo sokufinyelela, iswishi ibizwa ngokuthi iswishi yesendlalelo sokufinyelela, futhi uma isetshenziswa kungqimba yokuhlanganisa, inkinobho ibizwa ngokuthi iswishi yesendlalelo sokuhlanganisa.
Izici nomehluko wesendlalelo sokufinyelela, isendlalelo sokuhlanganisa nesendlalelo esiyinhloko
Isendlalelo esiyinhloko singanikeza ukudluliswa kwe-interzone okuphelele, isendlalelo sokuhlanganisa singanikeza ukuxhumana okusekelwe kunqubomgomo, futhi isendlalelo sokufinyelela singanikeza ukufinyelela komsebenzisi kunethiwekhi yezinhlelo zokusebenza zesevisi eziningi nezinye izinhlelo zokusebenza zenethiwekhi.
1. Isendlalelo sokufinyelela
Ngokuvamile ingxenye yenethiwekhi ebhekene ngqo nomsebenzisi ukuze axhume noma afinyelele inethiwekhi ibizwa ngokuthi isendlalelo sokufinyelela, esilingana nezisebenzi ezisezingeni eliphansi ekwakhiweni kwebhizinisi, ngakho-ke isendlalelo sokufinyelela.shintshainezindleko eziphansi nezici zokuminyana kwembobo ezisezingeni eliphezulu.
Isendlalelo sokufinyelela sinikeza abasebenzisi amandla okufinyelela isistimu yohlelo lokusebenza engxenyeni yenethiwekhi yendawo. Isendlalelo sokufinyelela sinikeza umkhawulokudonsa owanele wokufinyelela phakathi kwabasebenzisi abangomakhelwane. Isendlalelo sokufinyelela siphinde sibophezeleke ngemisebenzi yokuphatha yomsebenzisi (njengokufakazela ubuqiniso kwekheli kanye nokuqinisekiswa komsebenzisi) kanye nokuqoqwa kolwazi lomsebenzisi (njengamakheli e-IP, amakheli e-MAC, namalogi okufinyelela).
2. Isendlalelo sokuhlanganisa
Isendlalelo sokuhlanganisa, esaziwa nangokuthi isendlalelo sokusabalalisa, "singumlamuli" phakathi kwesendlalelo sokufinyelela kunethiwekhi kanye nesendlalelo esiyinhloko. Ilingana nokuphathwa okuphakathi kwenkampani futhi isetshenziselwa ukuxhuma isendlalelo esiyinhloko kanye nosendlalelo sokufinyelela. Esimeni esimaphakathi, isendlalelo sokuhlangana senziwa ngaphambi kokuba indawo yokusebenza ifinyelele isendlalelo esiyinhloko ukuze kuncishiswe umthwalo wamadivayisi wesendlalelo esiyinhloko.
Akunzima ukuqonda ukuthi isendlalelo sokuhlanganisa, esaziwa nangokuthi isendlalelo sokuhlanganisa, sinemisebenzi ehlukahlukene njengokusebenzisa izinqubomgomo, ukuphepha, ukufinyelela kweqembu lomsebenzi, umzila phakathi kwamanethiwekhi endawo abonakalayo (ama-vlans), kanye nokuhlunga kwekheli lomthombo noma indawo. Kusendlalelo sokuhlanganisa, ashintshaesekela ubuchwepheshe bokushintshwa kwe-Layer 3 futhi i-VLAN kufanele isetshenziselwe ukuzuza ukuhlukaniswa kwenethiwekhi nokuhlukaniswa.
3. Isendlalelo esiyinhloko
Isendlalelo esiyinhloko siwumgogodla wenethiwekhi, oqinisekisa ukusebenza kwayo yonke inethiwekhi, futhi imishini yayo ihlanganisaimizila, ama-firewall, amaswishi engqimba eyinhloko, njll., okulingana nokuphatha okuphezulu ekwakhiweni kwebhizinisi.
Isendlalelo esiwumgogodla besilokhu sibhekwa njengomamukeli wokugcina kanye nesihlanganisi sayo yonke i-traffic, ngakho-ke ukwakheka kwesendlalelo esiyinhloko kanye nezidingo zemishini yenethiwekhi ziqinile kakhulu, umsebenzi walo ngokuyinhloko ukufeza ukudluliselwa okuhle phakathi kwenethiwekhi yomgogodla, umsebenzi wokuklama ungqimba lwangemuva imvamisa ukugxila kokuphindaphindeka, ukwethembeka kanye nokudluliswa kwesivinini esikhulu. Ngakho-ke, kuyadingeka ukuthi amadivaysi engqimba eyinhloko asebenzise ikhophi yasenqolobaneni eshisayo ye-dual-system redundancy, futhi umsebenzi wokulinganisa umthwalo ungasetshenziswa ukuthuthukisa ukusebenza kwenethiwekhi. Umsebenzi wokulawula wenethiwekhi kufanele usetshenziswe kungqimba yomgogodla kancane ngangokunokwenzeka.
Umehluko phakathi kwesendlalelo sokufinyelelashintsha, isendlalelo sokuhlanganisashintshakanye ne-core layershintshayiphuzu eliyisihluthulelo lolwazi olungenhla. Ishintshaokukhulunywe ngenhla ngeyemikhiqizo yokuxhumana edayiswa ngokushisayo e-Shenzhen HDV Phoelectron Technology LTD., njenge: Ethernetshintsha, Isiteshi seFibershintsha, Isiteshi se-Ethernet Fibershintsha, njll., amaswishi angenhla angasetshenziswa ezindaweni ezihlukahlukene, ukunikeza ukukhetha okwengeziwe kubasebenzisi abanezidingo ezahlukene, siyakwamukela ukuqonda, sizohlinzeka ngesevisi yekhwalithi engcono kakhulu.
