Lefats'eng la lits'ebetso tsa marang-rang, li-switches tsa khoebo ke motheo oa likhokahano tse se nang moeli le phallo ea data ka har'a mokhatlo. Le hoja lisebelisoa tsena li ka shebahala joaloka mabokose a matšo ho ba sa tsebeng, tlhahlobo e haufi-ufi e senola kopano e entsoeng ka hloko ea likarolo tse sa tšoaneng, e 'ngoe le e' ngoe e bapala karolo ea bohlokoa ho netefatsa ts'ebetso e nepahetseng le ho tšepahala.
Ha re shebisiseng ts'ebetso ea kahare ea li-switches tsa khoebo mme re sibolle tapestry e rarahaneng ea likarolo tse etsang mokokotlo oa tharollo ea sejoale-joale ea marang-rang.
1. Bokhoni ba ho sebetsa:
Bohareng ba phetoho e 'ngoe le e' ngoe ea khoebo ke processor e matla e sebetsang e le setsi sa litaelo bakeng sa lits'ebetso tsohle. Li-processor tsena hangata ke li-CPU tse sebetsang hantle haholo kapa li-ASIC tse ikhethileng (li-circuits tse ikhethileng tsa ts'ebeliso) tse etsang mesebetsi ea bohlokoa joalo ka ho fetisa lipakete, ho tsamaisa le ho laola phihlello ka lebelo la lehalima le ho nepahala.
2. Mojule oa memori:
Li-module tsa memori, ho kenyelletsa le RAM (memori ea phihlello e sa reroang) le memori ea flash, e fana ka sesebelisoa ka lisebelisoa tse hlokahalang ho boloka le ho sebetsana le data. RAM e nolofalletsa phihlello e potlakileng ea tlhaiso-leseling e sebelisoang khafetsa, ha memori ea flash e sebetsa e le polokelo e tsitsitseng ea firmware, lifaele tsa tlhophiso le data ea ts'ebetso.
3. Boema-kepe ba Ethernet:
Li-port tsa Ethernet li theha sebopeho sa 'mele seo lisebelisoa li hokelang ho sona. Likou tsena li fumaneha ka mefuta e fapaneng ea litlhophiso, ho kenyeletsoa likou tsa khale tsa koporo tsa RJ45 bakeng sa likhokahano tsa likhoele le likhokahano tsa fiber optic bakeng sa litlhoko tsa marang-rang tse hole le tse lebelo le holimo.
4. Sebopeho sa phapanyetsano:
Lesela la ho fetola le emela mohaho oa ka hare o ikarabellang bakeng sa ho tsamaisa sephethephethe sa data pakeng tsa lisebelisoa tse hokahaneng. U sebelisa li-algorithms tse rarahaneng le ho sheba litafole, lesela le feto-fetohang le tsamaisa lipakete hantle ho ea moo li reriloeng teng, ho netefatsa latency e fokolang le ts'ebeliso e nepahetseng ea bandwidth.
5. Setsi sa phepelo ea motlakase (PSU):
Phepelo ea motlakase e tšepahalang e bohlokoa bakeng sa ts'ebetso e sa sitisoeng ea switching. Setsi sa phepelo ea motlakase (PSU) se fetola matla a kenang a AC kapa a DC hore a be matla a nepahetseng a hlokoang ke likarolo tse fetohang. Litlhophiso tse sa hlokeng letho tsa PSU li fana ka botsitso bo eketsehileng, ho netefatsa ts'ebetso e tsoelang pele ha ho ka etsahala hore motlakase o hlolehe.
6. Sistimi ea ho futhumatsa:
Ka lebaka la litlhoko tse matla tsa ts'ebetso ea li-switches tsa khoebo, sistimi e pholileng e sebetsang hantle e bohlokoa ho boloka mocheso o nepahetseng oa ts'ebetso le ho thibela mocheso o feteletseng. Licheso tsa mocheso, li-fan le mekhoa ea tsamaiso ea moea e sebetsa hammoho ho felisa mocheso o hlahisoang ke likarolo tse sebetsang le ho netefatsa ts'ebetso ea phetoho le bophelo ba tšebeletso.
7. Sehokelo sa tsamaiso:
Liphetoho tsa khoebo li na le lihokelo tsa tsamaiso tse kang dashboard e thehiloeng marang-rang, khokahanyo ea taelo ea mohala (CLI), le li-agents tsa SNMP (Simple Network Management Protocol) tse nolofalletsang batsamaisi ho hlophisa, ho beha leihlo le ho rarolla ts'ebetso ea marang-rang ba le hole. Likhokahano tsena li thusa lihlopha tsa IT ho boloka botšepehi ba marang-rang le ho rarolla mathata a hlahang ka tjantjello.
8. Likarolo tsa ts'ireletso:
Nakong ea litšokelo tse ntseng li eketseha tsa cyber, bokhoni bo matla ba ts'ireletso bo bohlokoa ho sireletsa data e hlokolosi le lisebelisoa tsa marang-rang. Liphetoho tsa likhoebo li kopanya mekhoa e tsoetseng pele ea ts'ireletso, ho kenyelletsa manane a taolo ea phihlello (ACLs), karohano ea VLAN, liprothokholo tsa encryption, le lits'ebetso tsa ho lemoha / thibelo ea ho kenella (IDS/IPS), ho thatafatsa li-perimeter tsa marang-rang khahlano le ts'ebetso e mpe.
ha re phethela:
Ho tloha ho matla a ho sebetsa ho ea ho liprothokholo tsa ts'ireletso, karolo e 'ngoe le e' ngoe ea khoebo e bapala karolo ea bohlokoa ho fana ka litharollo tsa marang-rang tse tšepahalang, tse sebetsang hantle. Ka ho utloisisa ho rarahana ha likarolo tsena, mekhatlo e ka etsa liqeto tse nang le tsebo ha e khetha le ho sebelisa lisebelisoa tsa marang-rang, ho rala motheo oa ecosystem ea IT e tsoetseng pele, e tsitsitseng le ea bopaki ba nako e tlang.
