Choyamba, tiyenera kumveketsa bwino lingaliro: zosinthira zosanjikiza zofikira, masiwichi ophatikizika, ndi masiwichi apakati sigawo ndi mawonekedwe a masiwichi, koma amagawidwa ndi ntchito zomwe amachita. Alibe zofunikira zokhazikika, ndipo makamaka zimadalira kukula kwa malo ochezera a pa Intaneti, mphamvu yotumizira chipangizocho, ndi malo omwe ali mumtundu wa intaneti. Mwachitsanzo, masinthidwe a Layer 2 omwewo atha kugwiritsidwa ntchito pagawo lofikira kapena pagulu lophatikizira pama network osiyanasiyana. Ikagwiritsidwa ntchito pagawo lofikira, chosinthiracho chimatchedwa switch layer yofikira, ndipo ikagwiritsidwa ntchito pagulu lophatikizira, chosinthiracho chimatchedwa switch aggregation layer.
Makhalidwe ndi kusiyana kwa kusanjikiza kofikira, kusanjikiza kosanjikiza ndi core layer
Chigawo chapakati chingapereke kufalitsa kwapakati pakatikati, kusanjikiza kophatikizana kungapereke mgwirizano wozikidwa pa ndondomeko, ndipo gawo lofikira lingapereke mwayi wogwiritsa ntchito maukonde ogwiritsira ntchito mautumiki ambiri ndi ntchito zina za intaneti.
1. Kufikira wosanjikiza
TUSally gawo la netiweki lomwe limayang'anizana mwachindunji ndi wogwiritsa ntchito kuti alumikizane kapena kulumikizana ndi netiweki amatchedwa gawo lofikira, lomwe limafanana ndi ogwira ntchito m'mizu yamakampani, kotero gawo lofikira.kusinthaali ndi mtengo wotsika komanso mawonekedwe apamwamba kwambiri adoko.
Gawo lofikira limapatsa ogwiritsa ntchito mwayi wopeza makina ogwiritsira ntchito pagawo lamaneti amderali. Gawo lofikira limapereka bandwidth yokwanira yofikira pakati pa ogwiritsa ntchito oyandikana nawo. Gawo lofikira limakhalanso ndi udindo woyang'anira ogwiritsa ntchito (monga kutsimikizira ma adilesi ndi kutsimikizika kwa ogwiritsa ntchito) komanso kusonkhanitsa zidziwitso za ogwiritsa ntchito (monga ma adilesi a IP, ma adilesi a MAC, ndi zolemba zofikira).
2. Aggregation wosanjikiza
The Aggregation layer, yomwe imadziwikanso kuti gawo logawa, ndi "mkhalapakati" pakati pa network access layer ndi core layer. Ndizofanana ndi kasamalidwe kapakati pa kampaniyo ndipo imagwiritsidwa ntchito kulumikiza gawo lapakati ndi gawo lofikira. Pamalo apakati, kusanja kwa convergence kumachitika pamaso pa malo ogwirira ntchito kukafika pachimake kuti kuchepetsa katundu wa zida zapakati.
Sikovuta kumvetsetsa kuti kusanjikizana, komwe kumadziwikanso kuti kusanjikiza, kumakhala ndi ntchito zosiyanasiyana monga kukhazikitsa mfundo, chitetezo, mwayi wamagulu ogwirira ntchito, kuyendetsa pakati pa ma netiweki amdera lanu (vlans), komanso kusefa magwero kapena kopita. M'magulu ophatikiza, akusinthayomwe imathandizira ukadaulo wosinthira wa Layer 3 ndipo VLAN iyenera kugwiritsidwa ntchito kukwaniritsa kudzipatula komanso kugawa magawo.
3. Chigawo chapakati
Chigawo chapakati ndi msana wa maukonde, omwe amatsimikizira kugwira ntchito kwa intaneti yonse, ndipo zida zake zikuphatikizapoma routers, zozimitsa moto, masiwichi apakati, ndi zina zambiri, zomwe ndizofanana ndi kasamalidwe kapamwamba pamapangidwe amakampani.
Chigawo chapakati nthawi zonse chimaganiziridwa kuti ndi cholandira chomaliza ndi chophatikizira magalimoto onse, kotero kuti mapangidwe apakati ndi zofunikira za zipangizo zamakono ndizokhwima kwambiri, ntchito yake makamaka ndi kukwaniritsa kufalikira kwabwino pakati pa maukonde a msana, ntchito yopangira msana kawirikawiri cholinga cha redundancy, kudalirika ndi kufala kwachangu. Chifukwa chake, ndikofunikira kuti zida zoyambira zosanjikiza zitengere zosunga zobwezeretsera zapawiri-system redundancy, ndipo ntchito yoyezera katundu itha kugwiritsidwanso ntchito kupititsa patsogolo magwiridwe antchito apaintaneti. Ntchito yoyang'anira maukonde iyenera kukhazikitsidwa pamsana wamsana pang'ono momwe mungathere.
Kusiyana pakati pa gawo lofikirakusintha, gulu la aggregationkusinthandi core layerkusinthandiye mfundo yofunikira ya chidziwitso pamwambapa. Thekusinthazomwe tatchulazi ndi za malonda kulankhulana otentha ku Shenzhen HDV Phoelectron Technology LTD., monga: Efanetikusintha, Fiber Channelkusintha, Ethernet Fiber Channelkusintha, etc., zosinthika pamwambazi zingagwiritsidwe ntchito m'madera osiyanasiyana, kuti apereke zosankha zambiri kwa ogwiritsa ntchito omwe ali ndi zosowa zosiyanasiyana, kulandiridwa kuti amvetse, tidzapereka ntchito yabwino kwambiri.
