Neeg tes hauj lwm - qhov yooj yim mechanism ntawm cov ntaub ntawv

Yuav ua li cas yog ib tug neeg computer network? Qhov no tej zaum yuav zoo tau lub tsev kawm ntawv ntaub ntawv chaw uas integrates yooj yim converged thauj infrastructure MPLS- administrative vaj tse, kev kawm thiab menyuam kawm ntawv lub tsev kawm ntawv. Nyob rau hauv tes hauj lwm no yam muaj ntsiab ntawm lub "tiam tom ntej no tes hauj lwm", yog li lawv muaj zoo scalability nyob rau hauv cov ntaub ntawv ntawm kev sib txuas lus kho qhov muag raws, Wi-nkaus. Yog li ntawd cia wb mus saib closer neeg tes hauj lwm.

qauv

Cov tes hauj lwm yuav tsum muaj high-ceev Internet, nkag mus computerized ntaub ntawv kev pab, cov internal VoIP-telephony kev koom ua ke nrog lub streaming nyob rau hauv ntev-deb li cas thiab tsam tes hauj lwm. Neeg ntaub ntawv network yuav tsum tsim kev kawm xov xwm thiab TV ntsiab lus, cov txheej txheem rau cov ntaub ntawv tis thiab yuav tsum tau mobile ib suab ib qho tseem ceeb cov txheej xwm. Cov kev pab txhawb nqa network los xyuas kom meej interoperability ntawm txawv units - multi-kev pab cuam thauj system kev cov ntaub ntawv kis tau tus mob (MTSPD). Yog hais tias peb tseem yuav tau xav txog lub neeg network ntawm lub University, nws yog raws li nyob rau hauv lub internal hauj lwm MTSPD niaj hnub cov exchanges nrog lub peev xwm ntawm 10 txhiab chav nrog tau streaming kev koom ua ke nyob rau hauv ntev-deb li cas thiab tsam tes hauj lwm.

hauv paus ntsiab lus ntawm cov lag luam

Workstations kev cob cog rua rau lub servers, uas yog tom qab ua ke los ntawm ib tug kev twb kev txuas apparatus. Neeg tes hauj lwm loj los ntawm xws li tshiab network feem los ntawm routers, kev sib txuas lus raws ntawm ntau hom ntawm repeaters. Lub Internet kev twb kev txuas yog ua tau los ntawm tshwj xeeb pab kiag li lawm thiab software rau kev tiv thaiv thiab tiv thaiv hauv cov network los ntawm sab nraum ntaub ( "hacking"). Cov thawj coj ntawm cov ntaub ntawv servers thiab databases, kev tshwj xeeb koom haum thiab kev ntsuas - lub ntsiab txoj kev los tiv thaiv cov ntaub ntawv nyob rau hauv lub nkag theem. Neeg tes hauj lwm raug muab faib ua virtual aav rau virtual networking yees (IEEE 802.1Q) rau muab cov kev kawm theem ntawm kev ruaj ntseg.

Cov telephony

Qhov no yog ib qho tseem ceeb heev lub caij uas cov neeg network ntawm kev sib txuas lus infrastructure. Xov tooj hu yog ua nyob rau hauv lub tuam txhab, bypassing nyob deb thiab tsam tes hauj lwm. Cov telephony system txhawb peb hom nrog cov neeg siv:

  • analog tes;
  • cov;
  • IP-telephony.

wireless Kev sib txuas lus

Xws li ib tug network uas yuav tsum tau los xyuas kom meej saib rau mobile neeg siv mus rau lub nrog cov kev pab thiab ntiaj teb no network.

Neeg tes hauj lwm muaj xws li wireless network xws li, ib tug nkag point, raws li zoo raws li neeg rau zaub mov kev tswj software.

IP-telephony

Niaj hnub nimno tus IP-telephony system nyob rau hauv neeg tes hauj lwm muaj xws li nyob rau hauv nws cov mej zeej hu tswj neeg rau zaub mov, firewalls, IP-tes. Siv cov IP-tes ua los ntawm uas twb muaj lawm LAN keyboards ncaj qha mus rau hauv lub tsev los yog nkag aggregation. Cov tshuaj no tso cai rau koj kom sai deploy ib tug heev xis mobile rooj sab laj chav ncaj qha nyob rau hauv cov kev tshwm sim hauv cheeb tsam.
