Tsanangudzo yeprotocol ndiyo yekutaurirana label yekoramu, mativi maviri ekutaurirana anofanirwa kuita pamwe chete kuita yakajairwa kufambisa data zvinoenderana nechiyero ichi. Mukukurukurirana kwekombuta, iyo nzira yekutaurirana inoshandiswa kuona kunyoreswa pakati pekombuta netiweki yekubatanidza, kana pasina yakabatana yekutaurirana protocol, kuendesa ruzivo pakati pemakomputa hakugone kuzivikanwa, iyo nzira yekutaurirana ndiyo mitemo yekutaurirana yakabvumiranwa ne mativi maviri pamberi. Inogona kungonzwisiswa semutauro wakajairika unoshandiswa nemakomputa kutaura kune mumwe nemumwe
Iyo protocol stack inoreva iyo chaiyo yekumisikidza fomu yeprotocol, isu tinowanzo kutaura ibasa reraibhurari rinoitwa nekodhi, kuitira kufambisa kufona kwemugadziri. Protocol stack ihuwandu hwemaprotocol mune yega yega yetiweki, uye mufananidzo wayo unoratidza mafaera ekufambisa munetiweki. Kubva kuprotocol yepamusoro kusvika kune yakaderera protocol, uye kubva paprotocol yepasi kusvika kune yepamusoro protocol.
Network vagadziri vanoshandisa hierarchical network architecture, nzira yekukurukurirana pakati pemauto maviri, kusanganisira kushandura michina, iyo protocol inoshanda senge stack, saka inonzi protocol stack.
Host a: Application layer- -> Transmission layer- -> Network layer- -> Data Link layer- -> Physical layer, inoenderana host b: Physical layer- -> Data Link layer- -> Network layer- -> Transmission layer- -> Application layer

VLAN inoreva iyo chaiyo yemunharaunda nharaunda network, iboka rezvishandiso zvine musoro uye vashandisi, kutaurirana pakati peboka iri remidziyo nevashandisi kwakafanana mune imwechete network segment, inogona kuve nzvimbo dzakasiyana, network dzakasiyana, vashandisi vakasiyana pamwe chete kuti vagadzire virtual. network nharaunda, sekushandiswa kweLAN yemuno seyakanaka, inochinjika, inoshanda. VLAN inogona kuderedza manejimendi mutengo wekufambisa kana kushandura nzvimbo yenzvimbo dzekushandira, kunyanya kune mamwe makambani anogara achichinja mumamiriro ebhizinesi, chikamu ichi chemutengo wekutarisira chakaderedzwa zvakanyanya.
Kuzviparadzanisa kweVlan kunoenderana nebasa reVlan tekinoroji, kuburikidza nechikamu cheVlan chezviteshi zvakasiyana, zviteshi zvemidziyo, vashandisi kuti vawane kuparadzaniswa kwakazara kwebhizinesi data.

16, Broadband uye Dial-up
Taishandisa ADSL Broadband. ADSL: Asymmetric Digital Subscriber Line.
Broadband inoshandiswa nekubatanidza tambo yerunhare kubva kune yako Broadband inotakura kuenda kune yako yemukati modem (inowanzozivikanwa sekatsi) uyezve kushandisa tambo kubatanidza kune zvimwe midziyo yakabatana neInternet.
Mushure memakore ebudiriro, ADSL yakapfuura nemuzvizvarwa zvitatu, kubva kune yekutanga ADSL kusvika kune yakazovandudzwa ADSL2 uye ikozvino ADSL2 +, iyo yekurodha yekumhanyisa ikozvino inogona kusvika kusvika 24M. ADSL inoshandisa frequency division multiplexing kuona kuti nharembozha, uplink uye downlink masiginecha hazvikanganise mumwe nemumwe.
Nhasi, kushandiswa kwakawanda kwefiber kumba (FTTH), mushure mezvose, kukurumidza kwekufambisa kwechiedza kupfuura kumhanya kwemagetsi ekufambisa, kwakanyanya kushanda. FTTH inoshanda nekudhonza fiber optic kubva kune inotakura kuenda kumba kwako uye kuibatanidza nemwenje modem (inowanzozivikanwa seyakajeka katsi). Wobva washandisa tambo yeInternet kubva pakatsi yechiedza kutungamirira kuInternet.
Dial-up Internet kazhinji inoreva PPPoe dial-up, inova nzira yekuwana iyo Internet, zvese ADSL Broadband dial-up (nhare yekufambisa tambo) uye fiber optic dial-up (fiber optic transmission). PPPoe inoreva Point-to-Point Protocol Pamusoro peEthernet, zvinoreva kuti kune mbiri mbiri dze server uye mutengi mune point-to-point protocol PPPoe paInternet. Mushandi anogamuchira uye anotumira ruzivo kune mutengi wevashandisiwo zvavo sevhavha, inova imwe-kune-vakawanda topology. Kuti usiyanise kuzivikanwa uye kugona kwemutengi wega wega, mushandisi wega wega anofanirwa kunyoresa account nepassword mune opareta, uye oisa iyo account nepassword pakombuta yake achishandisa chaiyo software kuti atumire kune server yeanoshanda. Kana akaundi yacho iri pamutemo, anogona kushandisa Indaneti nguva dzose. Ehe, dzimwe nguva tinozoona kuti tinogona kupinda Indaneti pasina kuisa password yeakaundi mukombuta. Izvi zvinodaro nekuti iyo account password yakagadzikwa pane katsi, saka isu hatifanirwe kuiisa nemaoko.
Iri pamusoro itsananguro pfupi yebroadband uye dial-up yakaunzwa neShenzhen HDV Phoelectron Technology Co., LTD. Iyo yakakodzera network michina yeShenzhen HDV Phoelectron Technology Co., Ltd. ine software inoenderana nezvigadzirwa zvedu, izvi zvigadzirwa zvenetiweki ndizvo.ONUseries, optical module series,OLTseries, transceiver series.
