Nkhaniyi idabadwa potengera nkhaniyi . Sindikugwirizana ndi malingaliro ambiri a wolemba, ndipo m'nkhaniyi sindikufuna kuti ndiwatsutse, komanso ndipereke malingaliro anga, omwe ndidzawateteza mu ndemanga. Kenako, ndilankhula za mfundo zingapo zomwe ndimatsatira popanga netiweki yakomweko pabizinesi iliyonse.
Mfundo yoyamba ndi yodalirika. Maukonde osadalirika nthawi zonse amakhala okwera mtengo kwambiri chifukwa cha mtengo wake wokonza, kutayika kwa nthawi yocheperako komanso kutayika kwa kusokoneza kwakunja. Kutengera mfundo iyi, nthawi zonse ndimapanga ma netiweki akuluakulu okhala ndi mawaya, ndipo, ngati kuli kofunikira, yowonjezera opanda zingwe (maukonde a alendo kapena maukonde olumikizira mafoni). Chifukwa chiyani maukonde opanda zingwe sadali odalirika? Netiweki iliyonse yopanda zingwe imakhala ndi zovuta zingapo zachitetezo, zokhazikika komanso zogwirizana. Zowopsa zambiri kwa kampani yayikulu.
Kudalirika kumatsimikiziranso kapangidwe ka maukonde. Topology ya "nyenyezi" ndi njira yabwino yomwe tiyenera kuyesetsa. "Star" amachepetsa chiwerengero chofunikira cha masiwichi, kuchuluka kwa mizere yowopsa ya thunthu, ndikuthandizira kukonza. Ndikosavuta bwanji kuyang'ana vuto mu switch imodzi kusiyana ndi angapo amwazikana m'maofesi, monga momwe mlembi wa nkhani yomwe tatchulayi ikuwonetsa. Sizopanda pake kuti mawu oti "kusintha zoo" amagwiritsidwa ntchito.
Koma nthawi zambiri pochita kumafunikabe kugwiritsa ntchito "fractal star" kapena "mixed topology" topology. Izi ndichifukwa cha mtunda wocheperako kuchokera ku zida zosinthira kupita kumalo ogwirira ntchito. Ichi ndichifukwa chake ndikukhulupirira kuti ma optical network pamapeto pake adzalowa m'malo opotoka.
Ngati sizingatheke kuyika masiwichi onse pamalo amodzi, ndiye kuti ndibwino kugwiritsa ntchito topology yosakanikirana, chifukwa mitengo ikuluikulu yonse idzatenga njira zosiyanasiyana, zomwe zidzachepetsa mwayi wowonongeka munthawi imodzi kumitengo ingapo.
Kulankhula za mitengo ikuluikulu. Masinthidwe olumikizidwa ndi mizere ya thunthu ayenera kukhala ndi njira yosunga zobwezeretsera nthawi zonse, ndiye ngati mzere umodzi wawonongeka, kulumikizana pakati pa node kudzakhalabe ndipo palibe kulumikizana kumodzi komwe kudzasweka. Mutha kutenga nthawi ndikulimbitsanso waya wowonongeka. Chifukwa chake, pamitengo ikuluikulu, ngakhale patali pang'ono, mutha kugwiritsa ntchito chingwe chachangu komanso chocheperako.
Mfundo yachiwiri yomanga scs ndi yomveka komanso yothandiza. Ndizomveka zomwe sizilola kugwiritsa ntchito ma optics "amakono" polumikiza malo ogwirira ntchito ndi zida zina zapaintaneti. Monga mlembi wa nkhani yomwe tatchulayi molondola, zonse tsopano zikugwira ntchito pa chingwe chopotoka. Ndizothandiza kwambiri. Koma pali zochepa zomwe zingagwire ntchito kudzera pamayendedwe opangira popanda zida zowonjezera. Ndipo chipangizo chilichonse chowonjezera sichingokhala pachiwopsezo komanso mtengo wowonjezera. Koma ili likadali mtsogolo. Tsiku lina, pafupifupi chipangizo chilichonse chikakhala ndi cholumikizira cholumikizira, ma optics adzalowa m'malo mwa zingwe zopotoka.
Kulingalira komanso kuchita bwino kungawonetsedwenso mu kuchuluka kwa soketi za rj45 pantchito. Ndizothandiza kugwiritsa ntchito soketi 2 pamalo aliwonse. Mzere wachiwiri ungagwiritsidwe ntchito, mwachitsanzo, kulumikiza foni ya analogi (ya digito), kapena kungokhala zosunga zobwezeretsera. Umu ndi momwe SCS imapangidwira makampani akuluakulu. Kwa mabizinesi ang'onoang'ono ndi apakatikati, ndizomveka kugwiritsa ntchito socket imodzi yapakompyuta pamalo antchito, popeza mafoni a IP nthawi zambiri amakhala ndi madoko awiri - ulalo womwe ukubwera ndi wachiwiri kulumikiza kompyuta kudzera pamenepo. Kwa osindikiza maukonde, nthawi zonse amalangizidwa kuti apange malo ogwirira ntchito osiyana, ndikupeza, ngati n'kotheka, mosavuta kwa ogwira ntchito onse omwe amagwiritsa ntchito, mwachitsanzo m'makonde. Munthu wodziwa bwino ntchito ya IT ayenera kusankha chomwe chili chofunikira kwambiri - kulingalira kapena kuchita, popeza tonse timadziwa bwino zomwe oyang'anira amakonda kusankha.
Palinso mfundo ina yofunika yomwe ndinganene kuti ndi yomveka komanso yothandiza. Izi ndi zomveka redundancy. Ndizothandiza kwambiri kukhala ndi malo ogwirira ntchito ambiri m'maofesi monga momwe antchito angakwanitse, m'malo mokhala ndi angati omwe akugwira ntchito kumeneko. Apanso, wogwira ntchito waluso yemwe ali ndi lingaliro la luso lazachuma la kampaniyo ndipo amamvetsetsa kuti pazopempha zatsopano, ayenera kusankha njira yothetsera vuto la kusowa kwa malo.
Ndipo ndithudi, mfundo ya kulingalira ndi kuchitapo kanthu kumaphatikizapo kusankha zipangizo ndi zipangizo. Mwachitsanzo, ngati kampani ndi yaying'ono ndipo ilibe mwayi wogwiritsa ntchito woyang'anira maukonde oyenerera omwe amatha kugwira ntchito ndi masiwichi a L2, ndizomveka kugwiritsa ntchito masiwichi osayendetsedwa, pomwe payenera kukhala mitengo ikuluikulu yosunga zobwezeretsera, ngakhale sakugwira ntchito. Palibe chifukwa chosungira pazinthu. Kugwiritsa ntchito zopotoka zamkuwa m'malo mwa mkuwa kumatanthauza kuti m'zaka zingapo mumatsimikiziridwa kukumana ndi vuto la kugwirizana koyipa. Kukana mapanelo, zingwe za fakitale ndi okonza kumatanthauza kuti pakapita nthawi mudzakhala ndi chisokonezo mu chipinda, nthawi zonse "kugwa" maulalo ndi okosijeni wa zolumikizira. Simuyeneranso kudumpha pa kabati ya seva. Kukula kwakukulu sikudzakulolani kuti mukhale ndi zipangizo zambiri, komanso kudzakhala kosavuta kusamalira.
Osadumphadumpha zingwe. Zingwe zabwino za fakitale ziyenera kupezeka kuntchito komanso mu kabati ya seva. Ngati muwerengera nthawi yomwe crimping zolumikizira ndi mtengo wa zida, ndiye kugula fakitale chigamba chingwe adzakhala otsika mtengo. Kuphatikiza apo, chingwecho chidzakhala cholimba, zolumikizira zitha kukhala zoyipa, zolumikizira zitha kukhala oxidize mwachangu, chida cha crimping chingakhale choyipa, diso limatha kukhala losawoneka bwino, ndipo pali zifukwa zina zambiri zosagwiritsa ntchito chingwe chopangira tokha.
Malingaliro anga, ngati palibe chifukwa choti malo ogwirira ntchito azigwira ntchito pa liwiro la 10G, ndizomveka kugwiritsa ntchito chingwe chopotoka cha gulu la 5e m'malo mwa gulu la 6, chifukwa sizotsika mtengo, komanso zowonda, zosinthika komanso chifukwa chake. yabwino kwambiri kukhazikitsa.
Ndipo potsiriza, mfundo yachitatu ndi yadongosolo. Kukula kwa netiweki, m'pamenenso dongosololi limafunikira kwambiri. Masiketi ndi madoko a mapanelo azigamba ayenera kuwerengedwa. Kuwerengera nthawi zambiri kumayambira kumalo ogwirira ntchito kuchokera kumanzere kupita kumanja kuchokera pakhomo la chipinda. Payenera kukhala pulani yapansi yovomerezeka yokhala ndi malo ndi manambala a malo ogulitsira.
Ndizochita zadongosolo osati zolekanitsa ma netiweki omwe amagwiritsidwa ntchito. Ngati mlembi wa "kawirikawiri kutchulidwa" nkhani akuganiza kuti palibe chapadera chosinthira mu chipinda chake, ndiye kuti sitingakwanitse.
Ndizomwezo. Mfundo zitatu izi zimatsimikizira projekiti yanga iliyonse ya SCS. M'nkhaniyi sindinathe kukhudza chilichonse, mwina ndinaphonya zambiri, ndipo mwina ndalakwitsa kwinakwake. NthaΕ΅i zonse ndimakhala wokonzekera kukambitsirana kolimbikitsa ngati ndipatsidwa kapepala koitanira anthu kusukulu kapena mβmakalata aumwini.
