Kalasi ya Changfei: Kusiyana Pakati pa Njira Imodzi ndi Multimode Fiber Optic Transceivers

Choyamba, tiyeni tiyang'ane pa:

Kusintha koyambira si mtundu wosinthira,
Ndilo kusintha komwe kumayikidwa pachimake (network backbone).
1. Chosinthira pachimake ndi chiyani

Nthawi zambiri, ma network akuluakulu amabizinesi ndi malo odyera pa intaneti amafunikira kugula masiwichi oyambira kuti athe kukulitsa luso lokulitsa maukonde ndikuteteza ndalama zomwe zilipo kale. Pokhapokha chiwerengero cha makompyuta chikafika pamlingo wina chikhoza kugwiritsidwa ntchito, pomwe palibe chifukwa chosinthira pamunsi pa 50, ndipo mayendedwe ndi okwanira. Chomwe chimatchedwa core switch chimatanthawuza kamangidwe ka maukonde. Ngati ndi netiweki yaying'ono yam'deralo yokhala ndi makompyuta angapo, chosinthira chaching'ono chokhala ndi madoko 8 chimatchedwa core switch. Masiwichi apakati nthawi zambiri amatanthauza masiwichi a Layer 2 kapena Layer 3 omwe ali ndi magwiridwe antchito a netiweki komanso kutulutsa kwamphamvu. Pamalo ochezera a pa intaneti omwe ali ndi makompyuta opitilira 100, kusintha koyambira ndikofunikira kuti pakhale ntchito yokhazikika komanso yothamanga kwambiri.

2. Kusiyana pakati pa masiwichi oyambira ndi okhazikika

masiwichi: Chiwerengero cha madoko omwe amasinthidwa pafupipafupi amakhala 24-48, ndipo madoko ambiri amtaneti ndi madoko a gigabit Ethernet kapena gigabit Ethernet. Ntchito yaikulu ndikupeza deta ya ogwiritsa ntchito kapena kusonkhanitsa deta yosintha kuchokera kumagulu ena ofikira. Kusintha kwamtunduwu kumatha kukhazikitsidwa ndi Vlan yosavuta routing protocol ndi zina zosavuta za SNMP nthawi zambiri, ndipo bandwidth yakumbuyo ndi yaying'ono. Pali madoko ambiri osinthira ma core switch, omwe nthawi zambiri amakhala modular ndipo amatha kuphatikizidwa momasuka ndi madoko owoneka bwino ndi madoko a gigabit Ethernet. Nthawi zambiri, masiwichi apakati ndi masiwichi osanjikiza atatu omwe amatha kukhazikitsa ma protocol osiyanasiyana apamwamba pa intaneti monga ma routing protocol/ACL/QoS/load balancing. Mfundo yofunika kwambiri ndi yakuti bandwidth ya backplane ya masiwichi oyambira ndi apamwamba kwambiri kuposa ma switch okhazikika, ndipo amakhala ndi ma module a injini ndipo ndi oyambira komanso osunga zobwezeretsera. Kusiyana pakati pa ogwiritsa ntchito kulumikiza kapena kupeza maukonde: Gawo la netiweki lomwe limayang'anizana mwachindunji ndi ogwiritsa ntchito kulumikiza kapena kulowa pamaneti nthawi zambiri limatchedwa gawo lofikira, ndipo gawo lomwe lili pakati pa gawo lofikira ndi gawo loyambira limatchedwa kugawa. wosanjikiza kapena wosanjikiza. Cholinga cha gawo lofikira ndikulola ogwiritsa ntchito kumapeto kuti alumikizane ndi netiweki, kotero chosinthira chosanjikiza chofikira chimakhala ndi mawonekedwe otsika mtengo komanso kachulukidwe ka doko. Kusintha kosanjikiza kosanjikiza ndi malo olumikizirana osinthika angapo, omwe amayenera kuthana ndi magalimoto onse kuchokera pazida zosanjikiza ndikupereka uplink ku gawo loyambira. Chifukwa chake, masinthidwe ophatikizika amakhala ndi magwiridwe antchito apamwamba, zolumikizira zochepa, komanso kusintha kwakukulu. Msana wa maukonde amatchedwa pachimake wosanjikiza, amene cholinga chachikulu ndi kupereka wokometsedwa ndi odalirika msana kufala dongosolo kudzera mkulu-liwiro kutumiza mauthenga. Chifukwa chake, pulogalamu yosinthira yoyambira imakhala yodalirika kwambiri, magwiridwe antchito, komanso kupitilira.
Poyerekeza ndi masiwichi wamba wamba, amayenera kukhala ndi zinthu monga cache yayikulu, kuchuluka kwamphamvu, virtualization, scalability, ndi ukadaulo wa module redundancy. Pakali pano, msika wosinthika umasakanizika, ndipo khalidwe la mankhwala ndilosiyana. Ogwiritsa ntchito amatha kulabadira CF FIBERLINK posankha zinthu, ndipo pali chosinthira chimodzi choyenera kwa inu!
