Utloisisa melemo ea li-switch tsa Ethernet tsa indasteri tse laoloang

Tikolohong ea kajeno ea indasteri e ntseng e tsoela pele ka potlako, tlhokahalo ea likhokahano tse tšepahalang le tse sebetsang hantle li bohlokoa ho feta pele.Li-switch tsa Ethernet tsa indasteriphetha karolo ea bohlokoa ho netefatsa phetiso ea data e se nang moeli le khokahanyo ea marang-rang libakeng tsa indasteri. Har'a mefuta e fapaneng ea li-switch tsa Ethernet tsa indasteri, li-switches tse laoloang li hlahella bakeng sa likarolo tsa tsona tse tsoetseng pele le ts'ebetso. Sengoliloeng sena, re tla shebisisa melemo ea li-switch tsa Ethernet tsa indasteri tse laoloang le hore na ke hobaneng li le bohlokoa bakeng sa lits'ebetso tsa sejoale-joale tsa indasteri.

Li-switch tsa Ethernet tsa indasteri tse laoloang li fana ka boemo bo holimo ba taolo le boits'oaro ho feta li-switches tse sa laoleheng. Ka li-switches tse laoloang, batsamaisi ba marang-rang ba ka lokisa le ho laola litlhophiso tsa ho fetola, ho beha sephethephethe pele, ho shebella ts'ebetso ea marang-rang, le ho kenya ts'ebetsong mehato ea ts'ireletso. Boemo bona ba taolo ke ba bohlokoa haholo libakeng tsa indasteri moo ho ts'epahala le ts'ireletso ea marang-rang e leng tsa bohlokoa.

E 'ngoe ea melemo e ka sehloohong ea ho tsamaisoali-switches tsa Ethernet tsa indasterike bokhoni ba bona ba ho tšehetsa likarolo tsa boleng ba tšebeletso (QoS). QoS e lumella sephethephethe sa data sa bohlokoa hore se etelletsoe pele, ho netefatsa hore tlhahisoleseling e sa tsotelleng nako e kang matšoao a taolo kapa data ea nako ea nnete ea ho lekola e beoa pele ho sephethephethe se seng sa bohlokoa. Bokhoni bona bo bohlokoa haholo lits'ebetsong tsa liindasteri le taolong, moo likhokahano tsa nako ea nnete li leng bohlokoa ho boloka ts'ebetso e sebetsang hantle le polokeho.

Ntle le moo, li-switches tse laoloang li fana ka likarolo tse ntlafalitsoeng tsa ts'ireletso ea marang-rang, ho kenyelletsa lethathamo la taolo ea phihlello, ts'ireletso ea boema-kepe, le ts'ehetso ea LAN (VLAN). Mehato ena ea ts'ireletso e thusa ho sireletsa marang-rang a indasteri ho tsoa phihlellong e sa lumelloeng, ho qhekella le litšokelo tse ka bang teng ka cyber. Nakong ea li-cyberattacks tse ntseng li eketseha tsa indasteri, likarolo tse matla tsa ts'ireletso tse fanoang ke li-switches tse laoloang li bohlokoa ho sireletsa lisebelisoa tsa bohlokoa le lintlha tse hlokolosi.

Monyetla o mong oa li-switch tsa Ethernet tsa indasteri tse laoloang ke ts'ehetso ea liprothokholo tsa tsamaiso e tsoetseng pele joalo ka Simple Network Management Protocol (SNMP) le Remote Monitoring and Control (RMON). Liprothokholo tsena li thusa ho lekola marang-rang, ho ntlafatsa ts'ebetso, le ho rarolla mathata, ho lumella batsamaisi ho tseba le ho rarolla mathata a ka bang teng pele a ama ts'ebetso. Bokhoni ba ho beha leihlo le ho laola marang-rang a indasteri bo molemo haholo bakeng sa lits'ebeletso tse kholo tsa indasteri le lits'ebetso tse ajoang.

Ho phaella moo, li-switches tse laoloang li fana ka phetoho e kholoanyane le scalability, e lumellang ho thehoa ha li-topology tse rarahaneng tsa marang-rang le ho kopanya lisebelisoa tse sa tšoaneng tsa indasteri le li-protocol. Ebang ho hokahanya li-PLC, li-HMI, li-sensor kapa lisebelisoa tse ling tsa indasteri, li-switches tse laoloang li fana ka ts'ebetso e hlokahalang ho finyella litlhoko tse fapaneng tsa marang-rang. Ho feta moo, bokhoni ba ho arola marang-rang ka ho sebelisa li-VLAN bo thusa ho laola sephethephethe hantle le ho itšehla thajana ha lisebelisoa tsa bohlokoa kapa li-subsystems.

Ka kakaretso, melemo ea ho laoloali-switches tsa Ethernet tsa indasterili hlakile. Ho tloha taolong e ntlafetseng le ts'ireletso ho ea ho bokhoni ba tsamaiso e tsoetseng pele le ho tenyetseha, li-switches tse laoloang li bohlokoa bakeng sa lisebelisoa tsa morao-rao tsa indasteri. Ha marang-rang a liindasteri a ntse a tsoela pele ho fetoha le ho hola, karolo ea li-switches tse laoloang ho netefatsa hore likhokahano tse tšepahalang le tse sebetsang hantle li tla ba bohlokoa le ho feta. Ka ho utloisisa melemo ea li-switch tsa Ethernet tsa indasteri tse laoloang, likhoebo li ka etsa liqeto tse nang le tsebo ha li sebelisa marang-rang a matla le a tsitsitseng a indasteri.
