Gigabit masiwichi: Nsonga chifukwa chosankha

Wamakono wa m'deralo makompyuta ogwira ntchito zopezera - ntchito zimene posapita nthawi amakumana oyang'anira onse dongosolo. Kukweza interoperability makompyuta pamodzi kulenga zinthu mulingo woyenera kugwira ntchito kwa ogwira ntchito m'tsogolo adzatsogolera ndi kuwonjezeka mu kupambana kampani. Unit chachikulu, mtima wa maukonde aliyense olemera ndi gigabit masiwichi. Iwo amapereka yosalala Mipikisano yamazinga ndi mkulu-liwiro deta kutengerapo ndi nthambi chizindikiro. Kusankha olondola a mchitidwe chimadalira pa ntchito kwa maukonde ndi ogwira wonse.

Sinthani ndi likulu

Pitani - chipangizo lopereka mgwirizano wa makompyuta angapo mu LAN wosakwatiwa ndipo amakhala kusintha khalidwe la chizindikiro opatsirana. Chimodzimodzi ntchito yomweyo zimagwiridwa ndi zipangizo zina zopezera - likulu (ndi English Pankakhala -. Mfundo iliyonse mu maukonde). Komabe, posankha akatswiri akhala akulimbikitsidwa kupereka mmalo masiwichi lapansi. Chimayambitsa izi?

likulu ntchito angayerekezedwe ndi ntchito ya repeater ochiritsira - amalandira mbendera ndi patsogolo kwa makompyuta onse olumikizidwa, mosasamala chimene ndi kompyuta cholinga otaya zambiri. Chifukwa cha "misa yamakalata" LAN kudya "kupha" amenewa, yafupika mlingo kufala wonse. Komanso, ambiri munafuna Aang'onoang'ono kuti maukonde, ndi apamwamba Mwina mtanda wa mphepo - kumene nambala yaikulu mapaketi onyenga anatumiza pa maukonde.

Wamba Gigabit masiwichi yomweyo pambuyo kugwirizana si losiyana kwa likulu la. Koma pa nthawi, iwo apanga tebulo kusinthitsa, kapena mndandanda anatilamula wa Mac maadiresi makompyuta, malinga ndi zomwe deta paketi watumidwa m'tsogolo. Choncho, magwiridwe akadakwanitsira imayendetsedwa ndi maukonde.

Chiwerengero cha madoko ndi liwiro la

Magwiridwe LAN zimadalira zoikamo lophimba. Ngakhale zipangizo yotsika mtengo Mbali zambiri kuti kuziika popanda mamembala ena a gulu ili mtengo. Komabe, pamene inu kusankha ayenera kulabadira yekha kuti ena mwa magawo zofunika kwambiri. Woyamba ndi chiwerengero cha madoko. Izo zimatengera chiwerengero cha zipangizo zopezera kuti akhoza olumikizidwa kwa magetsi a. Childs, chiwerengero cha madoko zimasiyanasiyana 5 48. chizindikiro china chofunika kwambiri ndi ndalama deta - liwiro limene aliyense ukugwira gigabit kudoko lophimba lapansi. Ifeyo si zosakwana 1000 MB / gawo. Koma ambiri a zipangizo kuthandiza muyezo IEEE 802,3 Nway - galimoto-kudziwika paketi mlingo.

mphamvu

Bandiwifi - mankhwala chiwerengero cha madoko kwa mlingo pazipita deta. chizindikiro Kudziwa ntchito a dongosolo panthawi ya katundu pachimake. Optimally, chithunzi ichi adzakhala apamwamba, mtsinje deta kuchokera ma PC onse nthawi yomweyo. Mwachitsanzo, lophimba anu ali madoko 10 imathamanga mpaka 300 MB / s. mphamvu ndi 2 GB / s. Pa chapamwamba katundu madoko adzatha kupatsira otaya mudziwe 3 GB / s, amene ali poyerekeza bandiwifi lapansi. masiwichi Gigabit awa sadzatha kuthana ndi kufunika pachimake ndi choopsa ntchito ogwira lonse.

ntchito Network zimadalira mgwirizano Full-duplex ndi theka duplex. Mu Full-duplex mode, kufala kwa mapaketi deta amakulira mbali ziwiri - kuchokera lophimba pa kompyuta ndi mosemphanitsa. The mode theka duplex, chizindikiro imafalikira yekha mu njira imodzi. Anamanga-zofanana kupewa mikangano pa ntchito zipangizo zopezera ntchito modes osiyana.

Tsindikani

Posankha n'kuyamba Nkofunika kulabadira kukula kwa tebulo kusinthitsa zokhudza "maina" doko ku adiresi Mac kompyuta. chizindikiro ichi tiyenera kuyesetsa kwa chiwerengero cha ma PC pa maukonde anu. Nthawi kumene zipangizo kukumbukira sipadzakhala malo kujambula chipangizo latsopano network udzachotsa adiresi ya PC mocheperapo-ntchito, ndiyeno kachiwiri akuyamba kufufuza ake. Izi kwambiri amachepetsa ntchito.

Mumayenda Control Mbali tiyenera kukhala masiwichi onse gigabit, chifukwa chimateteza ku imfa deta. Mothandizidwa ndi zipangizo awiri "kukambirana" pakati pawo, imene dongosolo ndipo pamene kutumiza chizindikiro.

kasamalidwe lophimba

Malinga ndi mtundu wa masiwichi kulamulira ali m'magulu awiri - imayendetsedwa ndi unmanaged. Mbali yoyamba tili ndi chipangizo kwathunthu yoyenda yokha popanda kusintha zipangizo Buku ndi calibration. Ndi bwino yosayenera ofesi yaing'ono kapena maukonde kunyumba, chifukwa ali ndi mtengo wotsika, sikutanthauza alowererepo anthu. drawback Aika - otsika zokolola, amene salola ntchito zake kampani zikuluzikulu. Anakwanitsa Gigabit Sinthani komanso amatha mu mode basi, koma ali ndi zipangizo zosiyanasiyana imene mkulu akhoza kusintha ntchito yake mosavuta. oimira ambiri JetStream, TP-Link, D-Link. kwambiri sangathe awo - mtengo.

10 masiwichi gigabit

Mu malo mpikisano n'kofunika kwambiri kuti athe kusankha mofulumira ndi kulamula. Kuti zonsezi zitheke, m'pofunika kuti akonzekeretse ndi ogwira ntchito ndi masiwichi liwilo, kupereka ukuthamana kufulumizitsa 10 GB / s. Akuti panali makina onga pa msika kwa zaka zoposa 10 zapitazo. Komabe, iwo akugwirabe ntchito, ndi kuchotsa iwo sapezeka panobe.

Kulumikiza 10 gigabit lophimba, mungagwiritse ntchito CHIKWANGWANI chamawonedwe chingwe, twinax kapena wamba mkuwa waya muyezo UTP / FTP. Masiku ano, anthu otchuka ndi zipangizo kuti kulumikiza ochiritsira mkuwa waya. Iwo amapereka deta pa luso 10GBASE-T, ndi mtengo wotsika ndi kupanga maukonde monga kusintha ngati nkotheka. Payokha, ndi Dziwani m'mbuyo ngakhale ndi Intaneti Gigabit.

mavenda lophimba

Atsegula mndandanda wa Alcatel-Lucent kampani. OmniSwitch banja ake zipangizo cholinga yomanga a sing'anga ambiri, komanso chipangizo Intaneti kakang'ono ogwira pachimake. The zitsanzo OmniSwitch 6850E zimaonetseratu 10 Gigabit lophimba chikupezeka monga zapadera, koma mu OmniSwitch 6900 wamanga madoko 64 mkulu-liwiro kufala paketi.

Company D-Link ali osiyanasiyana nthumwi ziwiri zokha za gulu zipangizo. Lake 8-Port Gigabit Kompyuta Sinthani DXS-3600-16S amapereka kugwirizana PC kudzera amodzi doko SFP + koma mu DXS-3600-32S chitsanzo kale 24 cholumikizira ofanana. Onse zipangizo mpando kwa gawo thambo ndi amene adzatha kulumikiza zopezera luso 10GBASE-T.

Cisco kampani sangathe kukondweretsa zida. Komabe, limatithandiza yosafuna zambiri yothetsera mu mawonekedwe a zigawo pulagi-mu Mwachitsanzo, Nexus ndi chothandizira. Awa "Atalikulitsa" angagwiritsidwe ntchito kulumikiza Intaneti pogwiritsa chingwe mkuwa kapena kudzera CHIKWANGWANI kuwala.

HP akupereka ake masiwichi Gigabit zosowa za mabizinesi ang'onoang'ono ndi sing'anga. Imodzi mwa oimira olemekezeka ndi HP 6125G / XG, umene uli wosakanizidwa chipangizo - 1/10-gigabit lophimba. Oyeretsedwa 10 gigabit zitsanzo lophimba mndandanda anapereka 5820. Iwo kukhalabe liwiro ichi pa mipando SFP +. Komabe, mwa zipangizo angapezeke, ndi PoE-gigabit lophimba Industrial HP 5920 zino.

Kodi kusankha kwa maukonde kwanu?

Ngati inu ntchito mogwirizana opanda zingwe kwa kaphatikizidwe zipangizo kwa maukonde kunyumba n'zosatheka zosayenera chifukwa mitengo otsika deta ndi bwino kugwiritsa ntchito masiwichi unmanaged. Choyamba, iwo ndi mtengo. Kachiwiri, ndi wosavuta kulumikiza ndi sintha, sikutanthauza wosuta alowererepo. Njira adzakhala chitsanzo TP-KULUMIKIZANA TL-SG1008D. Siwichi 8 madoko kwa kugwirizana, ntchito ndi magetsi wagawo chikugwirizana ndi kubwereketsa ndi. kufala Data kungakupatseni imathamanga 1 GB / s.

mukhoza kusankha kuwala Gigabit TRENDnet kapena Asus kupanga magetsi ngati n'koyenera. Mtengo wa zipangizozi ndi pa mlingo yovomerezedwa, ndi magwiridwe awo ndi mutu zokwanira zosoŵa za maukonde kunyumba.
