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 koyenera kwa interzone, kusanjikiza kophatikizana kungapereke mgwirizano wozikidwa pa ndondomeko, ndipo gawo lofikira lingapereke mwayi wogwiritsa ntchito maukonde ogwiritsira ntchito ma multi-services ndi ma intaneti ena.
1. Kufikira wosanjikiza
TUSally gawo la netiweki lomwe limayang'anizana mwachindunji ndi wogwiritsa ntchito kuti alumikizane kapena kulumikizana ndi netiweki amatchedwa gawo lofikira, lomwe ndi lofanana ndi ogwira ntchito m'mabungwe amakampani, chifukwa chake chosinthira cholumikizira chimakhala ndi mtengo wotsika komanso doko lapamwamba. kachulukidwe makhalidwe.
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.Pagulu lophatikizana, chosinthira chomwe chimathandizira ukadaulo wosinthira wa Layer 3 ndi VLAN ziyenera kugwiritsidwa ntchito kukwaniritsa kudzipatula komanso kugawa magawo.
3. Chigawo chapakati
Chigawo chapakati ndi msana wa intaneti, womwe umatsimikizira kugwira ntchito kwa maukonde onse, ndipo zida zake zimaphatikizapo ma routers, ma firewall, ma switches apakati, ndi zina zotero, zomwe ziri zofanana ndi kasamalidwe kapamwamba mu zomangamanga zamakampani.
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.
Kusiyanitsa pakati pa kusintha kosanjikiza kofikira, kusintha kwakusanjikiza kophatikizana ndi chosinthira chapakati ndiye mfundo yofunika kwambiri pazomwe zili pamwambapa.Kusinthana kwatchulidwa pamwambapa ndi kwa malonda olankhulana otentha ku Shenzhen HDV Phoelectron Technology LTD., monga: Efaneti lophimba, CHIKWANGWANI Channel lophimba, Efaneti CHIKWANGWANI Channel lophimba, etc., masiwichi pamwamba angagwiritsidwe ntchito m'madera osiyanasiyana, kupereka zosankha zambiri kwa ogwiritsa ntchito omwe ali ndi zosowa zosiyanasiyana, kulandiridwa kuti mumvetse, tidzapereka chithandizo chabwino kwambiri.
