Li-switch tsa indasteri li fapane le li-routers tsa 4G tsa indasteri lintlheng tse latelang:

(1) Maemo a fapaneng a ho sebetsa

Phetoho ea pele ea indasteri e ne e sebetsa ho lera la khokahanyo ea data (molara oa 2) oa mohaho o bulehileng oa OSI / RM, 'me router ea 4G ea indasteri e ne e etselitsoe ho sebetsa lera la marang-rang la mohlala oa OSI. Kaha sesebelisoa sa indasteri se sebetsa karolong ea bobeli (data link layer) ea OSI, molao-motheo oa eona oa ho sebetsa o batla o le bonolo. Empa li-routers tsa 4G tsa indasteri li sebetsa karolong ea boraro (marang-rang) ea OSI, e ka fumanang boitsebiso bo bongata ba protocol, 'me li-routers tsa 4G tsa indasteri li ka etsa liqeto tse bohlale ho fetisa.

(2) Phatlalatso ea data e thehiloe linthong tse fapaneng

Liphetoho tsa indasteri li sebelisa liaterese tsa 'mele kapa liaterese tsa MAC ho fumana aterese ea moo data e romelloang teng. Li-routers tsa indasteri tsa 4G li sebelisa linomoro tsa ID (ke hore liaterese tsa IP) tsa marang-rang a fapaneng ho fumana aterese ea ho fetisa data. Aterese ea IP e kenngoa ts'ebetsong 'me e hlalosa marang-rang moo sesebelisoa se leng teng. Ka linako tse ling liaterese tsena tsa karolo ea boraro li boetse li bitsoa liaterese tsa protocol kapa liaterese tsa marang-rang. Hangata aterese ea MAC e hahiloe ka har'a hardware, e fanoeng ke moetsi oa karete ea marang-rang, 'me e tiisitsoe ka karete ea marang-rang,' me ka kakaretso e ke ke ea fetoloa. Aterese ea IP hangata e fanoa ke molaoli oa marang-rang kapa sistimi.

(3) Phetoho ea setso ea indasteri e ka arola sebaka sa likhohlano feela, eseng sebaka sa khaso; ha router ea 4G ea indasteri e ka arola sebaka sa phatlalatso. Likarolo tsa marang-rang tse hoketsoeng ke sesebelisoa sa indasteri li ntse li le sebakeng se le seng sa khaso, 'me lipakete tsa data tsa phatlalatso li tla fetisoa likarolong tsohle tsa marang-rang tse hokahaneng ke sesebelisoa sa indasteri, se ka lebisang ho tšehetso ea puisano le bofokoli ba ts'ireletso maemong a mang. Likarolo tsa marang-rang tse hokahaneng le router ea 4G ea indasteri li tla abeloa libaka tse fapaneng tsa phatlalatso, 'me data ea phatlalatso e ke ke ea feta router ea 4G ea indasteri.

Le hoja li-switches tsa indasteri tse ka holimo ho lera la boraro li na le mesebetsi ea VLAN, sebaka sa phatlalatso se ka boela sa aroloa, empa puisano pakeng tsa libaka tse nyenyane tsa phatlalatso e ke ke ea fetisoa, 'me puisano pakeng tsa bona e ntse e hloka router ea 4G ea indasteri.

(4) Router ea 4G ea indasteri e fana ka ts'ebeletso ea firewall. E fetisetsa feela lipakete tsa data tse nang le liaterese tse itseng, 'me ha e fetise lipakete tsa data tse sa tšehetseng li-protocol tsa routing le phetiso ea lipakete tsa data ho netweke e lebisitsoeng, e ka thibelang lifefo tsa phatlalatso.
