Uyini umehluko phakathi kokushintsha kweLayer 2 kanye neLayer 3?
2022-09-16
1. Amaleveli okusebenza ahlukene: Amaswishi esendlalelo sesi-2 asebenza kusendlalelo sesixhumanisi sedatha, futhi amaswishi Esendlalelo sesi-3 asebenza kungqimba yenethiwekhi. Ukushintsha kwe-Layer 3 akuphumeleli nje kuphela ukudlulisela phambili amaphakethe edatha ngesivinini esiphezulu, kodwa futhi kuzuzisa ukusebenza kahle kwenethiwekhi ngokuya ngokuhlukahluka...

Ukuthuthukiswa kwe-transceiver optical yocingo
2022-09-13
Ama-transceivers ocingo ezwe lethu athuthuke ngokushesha ngokuthuthukiswa kwemboni yokuqapha. Ukusuka ku-analog kuye kudijithali, bese kusuka kudijithali kuya ekuchazeni okuphezulu, ziqhubeka zithuthuka. Ngemuva kweminyaka yokuqongelela ubuchwepheshe, ba...

Ukushintshwa Kwendandatho Ephethwe Kusebenza Kanjani?
2022-09-14
Ngokuthuthuka kwemboni yezokuxhumana kanye nokwaziswa komnotho wezwe, imakethe yokushintshashintsha kwenethiwekhi yendandatho ephethwe ikhule kancane kancane. Ibiza kakhulu, iguquguquka kakhulu, ilula futhi kulula ukuyisebenzisa. Ubuchwepheshe be-Ethernet h...

Uyini umehluko phakathi kwe-switch kanye ne-fiber converter?
2022-09-07
I-Optical fiber transceiver iyithuluzi elibiza kakhulu futhi elivumelana nezimo. Ukusetshenziswa okuvamile ukuguqula amasignali kagesi ngamapheya asontekile abe amasignali okubona. Ngokuvamile isetshenziswa ezintambo zethusi ze-Ethernet ezingakwazi ukumbozwa futhi kufanele zisebenzise imicu yokubona ukuze ...

Iyini i-Ring network redundancy&IP protocol?
2022-09-05
Kuyini ukudayiswa kwenethiwekhi ye-Ring? Inethiwekhi yokukhala isebenzisa indandatho eqhubekayo ukuxhuma idivayisi ngayinye ndawonye. Iqinisekisa ukuthi isignali ethunyelwe idivayisi eyodwa ingabonwa yiwo wonke amanye amadivaysi eringini. Ukungadingeki kwenethiwekhi yeringi kubhekise ekutheni ingabe iwindi lisekela...
