Tus qauv hauv zos network hauv nws daim ntawv tam sim no (nruab nrab) tau tsim thaum kawg tau tsim ntau xyoo dhau los, qhov twg nws txoj kev loj hlob tau nres.
Ntawm ib sab, qhov zoo tshaj plaws yog yeeb ncuab ntawm qhov zoo, ntawm qhov tod tes, stagnation kuj tsis zoo heev. Ntxiv mus, raws li kev soj ntsuam ze dua, lub chaw ua haujlwm niaj hnub no, uas tso cai rau koj ua haujlwm yuav luag txhua qhov haujlwm ntawm lub chaw ua haujlwm ib txwm muaj, tuaj yeem tsim tau pheej yig dua thiab sai dua li kev ntseeg, thiab nws cov qauv tsim yuav yooj yim dua thiab muaj peev xwm ua tau ntau dua. Tsis ntseeg kuv? Cia peb sim ua kom tiav. Thiab cia peb pib nrog dab tsi yog suav tias yog qhov tseeb tso ntawm lub network.
SKS yog dab tsi?
Ib qho kev tsim kab hluav taws xob (SCS) raws li lub hauv paus kawg ntawm engineering infrastructure yog siv nyob rau hauv ob peb theem:
- tsim;
- ua tau, installation ntawm cable infrastructure;
- installation ntawm cov ntsiab lus nkag;
- installation ntawm switching cov ntsiab lus;
- commissioning ua hauj lwm.
Tsim
Txhua qhov haujlwm loj, yog tias koj xav ua kom zoo, pib nrog kev npaj. Rau SCS, qhov kev npaj no yog tsim. Nws yog nyob rau theem no uas nws tau coj mus rau hauv tus account tias yuav tsum tau muab ntau txoj haujlwm, pes tsawg qhov chaw nres nkoj yuav tsum nyob, thiab lub peev xwm muaj peev xwm yuav tsum tau muab tso rau. Nyob rau theem no, yuav tsum tau ua raws li cov qauv (ISO / IEC 11801, EN 50173, ANSI / TIA / EIA-568-A). Qhov tseeb, nws yog nyob rau theem no uas ciam teb muaj peev xwm ntawm cov tsim network tau txiav txim siab.
Cable infrastructure
Nyob rau theem no, tag nrho cov kab hluav taws xob tau muab tso rau kom ntseeg tau tias cov ntaub ntawv xa mus dhau lub network hauv zos. Kilometers ntawm tooj liab cable symmetrically twisted nyob rau hauv khub. Pua pua kilograms ntawm tooj liab. Qhov yuav tsum tau nruab rau lub thawv cable thiab cov tais - tsis muaj lawv, kev tsim kho cov kab hluav taws xob tsis yooj yim.
Cov ntsiab lus nkag
Txhawm rau muab cov chaw ua haujlwm nkag mus rau lub network, cov ntsiab lus nkag tau raug teeb tsa. Kev taw qhia los ntawm lub hauv paus ntsiab lus ntawm redundancy (ib qho tseem ceeb tshaj plaws hauv kev tsim kho ntawm SCS), cov ntsiab lus no tau muab tso rau hauv ntau tshaj qhov tsawg kawg nkaus uas yuav tsum tau muaj. Los ntawm kev sib piv nrog cov khoom siv hluav taws xob: qhov ntau qhov (sockets) muaj, qhov hloov tau yooj yim dua koj tuaj yeem siv qhov chaw uas muaj lub network zoo li no.
Hloov cov ntsiab lus, commissioning
Tom ntej no, lub ntsiab thiab, raws li ib qho kev xaiv, nruab nrab hloov cov ntsiab lus raug ntsia. Racks / telecom txee tau muab tso rau, cables thiab cov chaw nres nkoj raug cim, kev sib txuas tau ua rau hauv cov ntsiab lus sib sau ua ke thiab hauv qhov crossover node. Lub cav hloov pauv tau muab tso ua ke, uas yog tom qab hloov kho thoob plaws hauv lub neej tag nrho ntawm cable system.
Thaum tag nrho cov txheej txheem installation tiav, tag nrho cov kab ke raug sim. Cables txuas nrog cov khoom siv hauv lub network, thiab lub network tau tsim. Kev ua raws li qhov zaus bandwidth (kev sib kis ceev) tshaj tawm rau SCS tau raug kuaj xyuas, cov ntsiab lus nkag tau raug hu, thiab tag nrho lwm yam tseem ceeb rau kev ua haujlwm ntawm SCS raug kuaj xyuas. Tag nrho cov kev tsis txaus ntseeg raug tshem tawm. Tsuas yog tom qab no, lub network raug xa mus rau tus neeg siv khoom.
Lub cev nruab nrab rau kev xa cov ntaub ntawv yog npaj txhij. Tom ntej no yog dab tsi?
Dab tsi "nyob" hauv SCS?
Yav dhau los, cov ntaub ntawv los ntawm ntau lub tshuab, kaw rau lawv tus kheej thev naus laus zis thiab cov txheej txheem, raug xa mus rau cable infrastructure ntawm lub network hauv zos. Tab sis thev naus laus zis zoo tau ntev tau muab faib ua xoom. Thiab tam sim no hauv cheeb tsam hauv cheeb tsam muaj, kab tias, tsuas yog Ethernet sab laug. Xov tooj, vis dis aus los ntawm cov koob yees duab soj ntsuam, ceeb toom hluav taws, kev ruaj ntseg, cov ntaub ntawv ntsuas hluav taws xob, kev nkag mus rau kev tswj hwm thiab ntse intercom, thaum kawg - tag nrho cov no tam sim no mus rau saum Ethernet.
Ntse intercom, nkag mus tswj qhov system thiab chaw taws teeb tswj ntaus ntawv
Peb optimize cov infrastructure
Thiab cov lus nug tshwm sim: nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, peb puas tseem xav tau txhua qhov ntawm SCS ib txwm?
Hardware thiab software hloov
Nws yog lub sijhawm lees paub qhov pom tseeb: kho vajtse hloov ntawm theem ntawm kev sib txuas thiab cov hlua khi tau ua tiav nws qhov txiaj ntsig. Txhua yam tau ua tiav ntev los ntawm kev siv VLAN cov chaw nres nkoj, thiab cov thawj coj txheeb xyuas cov xov hlau hauv cov txee dai khaub ncaws thaum twg muaj kev hloov pauv hauv lub network qauv yog qhov cuam tshuam. Nws yog lub sijhawm los ua cov kauj ruam tom ntej thiab cia li tso cov ntoo khaub lig thiab patchcords.
Thiab nws zoo li ib qho me me, tab sis yog tias koj xav txog nws, yuav muaj txiaj ntsig ntau dua los ntawm cov kauj ruam no dua li los ntawm kev hloov mus rau cable ntawm pawg tom ntej. Txiav txim rau koj tus kheej:
- Qhov zoo ntawm lub cev teeb liab kis nruab nrab yuav nce.
- Kev ntseeg siab yuav nce ntxiv, vim tias peb tshem tawm ob ntawm peb cov neeg kho tshuab kev sib cuag los ntawm qhov system (!).
- Yog li ntawd, lub teeb liab kis tau tus mob yuav nce. Tsis tseem ceeb, tab sis tseem.
- Mam li nco dheev yuav muaj chaw nyob hauv koj lub txee dai khaub ncaws. Thiab, los ntawm txoj kev, yuav muaj ntau qhov kev txiav txim nyob ntawd. Thiab qhov no twb txuag nyiaj.
- Tus nqi ntawm cov cuab yeej tshem tawm yog me me, tab sis yog tias koj coj mus rau hauv tus account tag nrho cov nplai ntawm kev ua kom zoo, cov nyiaj khaws cia zoo kuj tuaj yeem sau tau.
- Yog tias tsis muaj kev sib txuas, koj tuaj yeem crimp tus neeg siv kab ncaj qha raws li RJ-45.
Yuav ua li cas? Peb simplified lub network, ua kom nws pheej yig dua, thiab tib lub sij hawm nws tau dhau los ua buggy tsawg thiab tswj tau ntau dua. Tag nrho qhov zoo!
Los yog tej zaum, ces, muab lwm yam pov tseg? π
Optical fiber ntau tsis yog tooj liab
Vim li cas peb thiaj xav tau kilometers ntawm twisted khub cable thaum tag nrho cov ntaub ntawv uas mus raws ib tug tuab bundles ntawm tooj liab xov hlau yuav kis tau yooj yim ntawm optical fiber? Cia peb nruab qhov hloov chaw 8-chaw nres nkoj hauv chaw ua haujlwm nrog kev kho qhov muag thiab, piv txwv li, kev txhawb nqa PoE. Los ntawm lub txee dai khaub ncaws mus rau qhov chaw ua hauj lwm muaj ib tug fiber optic core. Los ntawm kev hloov mus rau cov neeg siv khoom - tooj liab thaiv. Tib lub sijhawm, IP xov tooj lossis lub koob yees duab soj ntsuam tuaj yeem muab lub zog tam sim ntawd.
Nyob rau tib lub sijhawm, tsis yog tsuas yog qhov loj ntawm tooj liab cable nyob rau hauv zoo nkauj lattice tais raug tshem tawm, tab sis kuj cov nyiaj yuav tsum tau rau nteg tag nrho cov splendor no, tsoos rau SCS, tau txais kev cawmdim.
Muaj tseeb, xws li cov tswv yim sib txawv me ntsis cuam tshuam lub tswv yim ntawm "qhov tseeb" kev tso kawm ntawm cov khoom siv nyob rau hauv ib qho chaw, thiab kev txuag ntawm cable thiab multiport keyboards nrog tooj liab ports yuav raug siv rau kev yuav khoom me me nrog PoE thiab optics.
Nyob ntawm tus neeg siv khoom
Tus neeg siv-sab cable hnub rov qab mus rau lub sijhawm thaum wireless technology zoo li cov khoom ua si ntau dua li cov cuab yeej ua haujlwm tiag tiag. Niaj hnub no "wireless" yuav yooj yim muab speeds tsis tsawg tshaj li qhov uas ib tug cable tam sim no muab, tab sis yuav cia koj untie koj lub computer los ntawm ib tug taag kev twb kev txuas. Yog lawm, cov huab cua tsis yog roj hmab, thiab nws yuav tsis muaj peev xwm ua kom tsis muaj qhov kawg ntawm cov channel, tab sis, ua ntej, qhov kev ncua deb ntawm tus neeg siv mus rau qhov chaw nkag tuaj yeem me me (chaw ua haujlwm xav tau qhov no), thiab qhov thib ob, muaj twb yog hom tshiab thev naus laus zis uas siv piv txwv li, hluav taws xob kho qhov muag (piv txwv li, hu ua Li-Fi).
Nrog rau ntau yam yuav tsum tau nyob rau hauv 5-10 meters, txaus los mus cuag 2-5 cov neeg siv, qhov chaw nkag tau tag nrho cov kev txhawb nqa gigabit channel, raug nqi tsawg heev thiab ntseeg tau kiag li. Qhov no yuav cawm tus neeg siv kawg ntawm cov xov hlau.
Optical Hloov S thiab ib lub gigabit wireless router txuas nrog ib qho chaw kho qhov muag
Nyob rau yav tom ntej, lub sijhawm zoo li no yuav muab los ntawm cov cuab yeej ua haujlwm hauv millimeter nthwv dej (802.11ad / ay), tab sis rau tam sim no, txawm tias nyob rau qis qis, tab sis tseem tsis tau rov ua dua rau cov neeg ua haujlwm hauv chaw ua haujlwm, qhov no tuaj yeem ua tiav raws li 802.11. ac txheem.
Muaj tseeb, qhov no txoj hauv kev rau kev sib txuas cov khoom siv xws li IP xov tooj lossis lub koob yees duab yees duab hloov pauv. Ua ntej, lawv yuav tsum tau muab lub zog sib cais los ntawm kev siv hluav taws xob. Qhov thib ob, cov khoom siv no yuav tsum txhawb Wi-Fi. Txawm li cas los xij, tsis muaj leej twg txwv tsis pub tawm ntawm qee qhov chaw nres nkoj tooj liab ntawm qhov chaw nkag rau thawj zaug. Yam tsawg kawg rau kev rov qab sib raug zoo lossis qhov xav tau tsis tau pom dua.
Piv txwv li, ib tug wireless router , 802.11a/b/g/n, 802.11ac Wave 2, 4xGE RJ45, 1xSFP
Cov kauj ruam tom ntej yog logical, txoj cai?
Cia peb tsis txhob tso tseg. Cia peb txuas cov ntsiab lus nkag nrog fiber ntau optic cable nrog bandwidth ntawm, hais, 10 gigabits. Thiab cia peb tsis nco qab txog SCS ib txwm muaj xws li npau suav phem.
Lub tswv yim yuav yooj yim thiab elegant.
Hloov chaw ntawm cov txee thiab cov tais ntim nrog tooj liab, peb nruab ib lub txee me me uas muaj qhov hloov kho qhov muag "dozens" "nyob" rau txhua tus neeg siv 4-8, thiab peb txuas cov fiber ntau mus rau cov ntsiab lus. Yog tias tsim nyog, rau cov cuab yeej qub koj tuaj yeem tso qee qhov chaw nres nkoj "tooj liab" ntxiv ntawm no - lawv yuav tsis cuam tshuam nrog cov txheej txheem tseem ceeb hauv txhua txoj kev.
