Lefatšeng le potlakileng la marang-rang moo phallo ea data le khokahanyo li leng bohlokoa, li-switches tsa marang-rang ke mokokotlo oa mekhoa e metle ea puisano. Todahike ke moetapele oa tharollo ea marang-rang, a lula a fana ka li-switches tsa morao-rao tsa marang-rang ho likhoebo tsa motlakase le malapeng. Sehlooho sena se hlahloba phetoho ea li-switches tsa marang-rang le hore na Todahike e ka pele ho tsoelo-pele ena ea thekenoloji joang.
Tšimoloho ea Liphetoho tsa Network
Li-switches tsa marang-rang li ile tsa hlaha ho elella bofelong ba lilemo tsa bo-1980 le mathoasong a lilemo tsa bo-1990 e le phetoho ea libaka tsa marang-rang. Ho fapana le li-hubs, tse phatlalatsang lintlha ho lisebelisoa tsohle tse hokahaneng, li-switches li ka tsamaisa data ka bohlale ho lisebelisoa tse itseng, li eketsa haholo ts'ebetso ea marang-rang le lebelo. Todahike o ile a hlokomela bokhoni ba theknoloji ena esale pele mme a qala letoto la eona la pele la li-switches bohareng ba bo-1990, a beha litekanyetso tse ncha tsa ts'ebetso le ts'epo.
2000s: Ho phahama ha Gigabit Ethernet
Mathoasong a lilemo tsa 2000, theknoloji ea Gigabit Ethernet e ile ea amoheloa ka potlako, e fihla lebelo la 1 Gbps. Ena ke ho tlola ho hoholo hoa maemo a pele a 100 Mbps Fast Ethernet. Todahike e phatlalalitse letoto la li-switches tsa Gigabit ho fihlela tlhoko e ntseng e hola ea bandwidth e phahameng likhoebong le marang-rang a lapeng. E etselitsoe ho sebetsana le sephethephethe sa data se ntseng se hola, li-switch tsena li ts'ehetsa habonolo lits'ebetso tse joalo ka seboka sa video, media media le phetiso e kholo ea lifaele.
2010s: Ho kena nakong ea li-switches tse bohlale le tse laoloang
Ha marang-rang a ntse a rarahana le ho feta, tlhoko ea li-switches tse bohlale, tse bonolo ho li laola lia hola. Todahike e hlahisitse letoto la li-switches tse laoloang ka bohlale tse fanang ka batsamaisi ba marang-rang ka taolo e kholo le ponahalo. Li-switch tsena li na le likarolo tse tsoetseng pele joalo ka tšehetso ea VLAN, ho beoa pele ha boleng ba lits'ebeletso (QoS), le likarolo tse ntlafalitsoeng tsa ts'ireletso bakeng sa taolo e nepahetseng le e sireletsehileng ea marang-rang.
Mehla ea sejoale-joale: Ho amohela 10 GB ho ea holimo
Lilemong tsa morao tjena, ho sutumetsa ka lebelo le phahameng le ts'ebetso e ntle ho tsamaisitse nts'etsopele ea li-switch tsa 10 Gb Ethernet (10GbE). Todahike e 'nile ea e-ba ka pele ho phetoho ena, ho hlahisa moloko o mocha oa li-switches tse etselitsoeng ho finyella litlhoko tsa marang-rang a morao-rao a sebetsang hantle. Li-switch tsena tsa 10GbE li loketse litsi tsa data, maemo a phahameng a ts'ebetso ea likhomphutha, le likhoebo tse hlokang phetiso ea data e potlakileng haholo le latency e tlase.
Boitlamo ba Todahike ho Boqapi
Katleho ea Todahike 'marakeng oa switjha oa marang-rang e bakoa ke boitlamo ba eona bo sa thekeseleng ba ho nchafatsa le boleng. Khampani e lula e tsetela ho lipatlisiso le nts'etsopele ho tlisa tsoelo-pele ea morao-rao lihlahisoa tsa eona. Li-switches tsa Todahike li tsebahala ka matla a tsona, scalability le matla a matla, e leng se etsang hore e be khetho ea pele bakeng sa mefuta e fapaneng ea lisebelisoa.
Lisebelisoa tse tsoetseng pele bakeng sa lefats'e le hokahaneng
Liphetoho tsa morao-rao tsa Todahike li na le mefuta e mengata ea likarolo tse tsoetseng pele tse etselitsoeng ho fihlela litlhoko tsa marang-rang a sejoale-joale:
High port density: E fana ka palo e kholo ea likou ho amohela marang-rang a ntseng a hola.
Tšehetso ea PoE +: Matla holim'a Ethernet Plus (PoE +) e nolofalletsa lisebelisoa tsa motlakase tse kang lik'hamera tsa IP, lifono tsa VoIP, le libaka tsa ho kena ka mohala ka ho toba ho tloha thapo ea Ethernet.
Ts'ireletso e tsoetseng pele: Likarolo tse joalo ka manane a taolo ea phihlello (ACLs), ts'ireletso ea boema-kepe, le likarolo tsa marang-rang li sireletsa khahlanong le litšokelo tsa marang-rang.
Taolo e ntlafetseng: Sehokelo sa webo se hlakileng, sehokahanyi sa mola oa taelo (CLI), le ts'ehetso ea liprothokholo tsa taolo ea marang-rang joalo ka SNMP e nolofatsa taolo.
Redundancy le ho tšepahala: Likarolo tse kang Link Aggregation Control Protocol (LACP) le ts'ehetso bakeng sa phepelo ea motlakase e sa hlokahaleng e netefatsa hore marang-rang a tla sebetsa le ho tšepahala.
Ho sheba bokamoso
Ha sebaka sa marang-rang se ntse se tsoela pele ho fetoha, Todahike e ikemiselitse ho etella pele ka litharollo tse ncha ho fihlela litlhoko tse ntseng li hola tsa khokahanyo. Khampani e ntse e hlahloba bokhoni ba theknoloji e hlahang e kang 25GbE, 40GbE le 100GbE, hammoho le tsoelo-pele ea software-defined networking (SDN) le network function virtualization (NFV).
Ka bokhutšoanyane, ho phehella ho sa khaotseng ha lebelo le phahameng, tsamaiso e ntlafetseng, le ts'ireletso e ntlafetseng e tsamaisitse nts'etsopele ea li-switches tsa marang-rang. Boikemisetso ba Todahike ho boqapi bo e boloka e le ka pele ho nts'etsopele ena, e fana ka tharollo e thusang likhoebo le batho ka bomong ho fihlela ho feta. Ha re ntse re ea nakong e tlang, Todahike e ntse e ikemiselitse ho fana ka mahlale a morao-rao a marang-rang a hokahanyang lefatše ka litsela tse potlakileng, tse bohlale le tse sireletsehileng haholoanyane.
