Igama le- WAP liqukethe iinguqu ezimbini ezahlukeneyo kwihlabathi lokunxibelelana kwe-wireless. I-WAP imele i- Wireless Access Point neProtocol ye-Wireless Protocol .
Amanqaku okufikelela ezingenazintlu
Indawo yokufikelela engenazintambo yinkqubo edibanisa i-wireless (ngokuqhelekileyo i- Wi-Fi ) inethiwekhi yendawo kwi-network (ngokuqhelekileyo ye- Ethernet ) inethiwekhi.
Ukufumana ulwazi oluthe vetshe, jonga - Ziziphi iingongoma zokufikelela ezingenazintambo?
IProsoft Application Protocol
Iprotocol ye-Wireless Application yachazwa ukuxhasa ukuhanjiswa kwezinto eziphathekayo kwizixhobo eziphathekayo kwiinkonzo ezingenantambo. Ephambili kwiplani ye-WAP yinkqubo yenethiwekhi esekelwe kwi- OSI . I-WAP isebenzise iinkqubo ezininzi zokunxibelelanisa ezintsha ezenza imisebenzi efana neyohlukeneyo kodwa ihluke kwiiprotokholi zeWebhu ze- HTTP , iTCP kunye ne- SSL .
I-WAP ibandakanye iingcamango zezikhangeli, iinkonzo , ii-URL kunye neendlela zokunxibelelana . Iiphequluli ze-WAP zakhiwe kumadivayisi amancinci omnxeba njengeefowuni, ii-pagers kunye nee-PDA. Esikhundleni sokuphuhlisa umxholo kwi-HTML kunye neJavaScript, abathuthuli be-WAP basebenzisa i-WML kunye ne-WMLScript. Ukuxinwa kwiintambo zombini zomnatha kunye nokusetyenziswa kwamandla kwezixhobo, i-WAP isekela kuphela i-subset encane yokusetyenziswa kwe-PC. Izicelo zobuninzi bezobuchwephesha beziintlobo zeendaba, ukucaphulwa kwesitokisi kunye nokuthumela imiyalezo.
Nangona inani elifanelekileyo lamadivayisi anikwe amandla kwi-WAP bekhona kwimarike ukususela ngo-1999 ukuya kwiminyaka ye-2000, akuzange kuthathe ixesha elide ukuba iteknoloji ingagqibekanga kunye nokuphuculwa kweetheknoloji ngokukhawuleza kwintanethi yeselula kunye nee-smartphone.
I-Model Model
Umzekelo we-WAP unemiqolo emithathu kwisigxina, ukusuka phezulu ukuya phezulu: Isicelo, iSeshoni, Intsebenzo, Ukhuseleko kunye nezothutho.
Uluhlu lwesicelo se-WAP yi-Wireless Application Environment (WAE). U-WAE uxhasa ngokuthe ngqo ukuphuhliswa kwesicelo se-WAP ngeLwimi lokuLungisa iNtambo (WML) esikhundleni se-HTML kunye ne-WMLScript esikhundleni seJavaScript. I-WAE ikwaquka i-Wireless Telephony Application Interface (i-WTAI, okanye i-WTA efutshane) enika iinkqubo zenkqubo yokufowunela kwiifowuni zokuqalisa iifowuni, ukuthumela imiyalezo yombhalo kunye nezinye iindlela zokunxibelelana.
Iseshingi yeseshoni ye-WAP yiNkqubo ye-Wireless Session Protocol (WSP). I-WSP ilingana ne-HTTP ye-WAP. I-WAP iquka iiphequluli kunye neeseva nje njengeWebhu, kodwa i-HTTP ayilona ukhetho olufanelekileyo kwi-WAP ngenxa yokungafani kakuhle kwintambo. I-WSP igcina i-bandwidth exabisekileyo kwiinqhagamshelo ezingenazintambo; ngokukodwa, i-WSP isebenza ngeenkcukacha ezincinci ezinobumba apho i-HTTP isebenza ngokukodwa ngedatha yombhalo.
Iprotocol ye-Wireless Transaction Protocol (WTP) inikezela ngeenkonzo zesevisi yokuthengiswa kwezothutho kunye nokuthembeka. Ikhusela iikopi eziphindwe kabini kwiipakethi ukuba zifunyenwe ngendawo ekuya kuyo, kwaye ixhasa ukubuyiswa kwakhona, ukuba kuyimfuneko, kwiimeko apho amapakethi ehla. Kule ntetho, i-WTP ifana ne-TCP. Nangona kunjalo, iWTP nayo iyahluka kwiTCP. I-WTP ibaluleke kakhulu kwi-TCP edibeneyo eyenza ukusebenza komsebenzi okongezelelweyo kwi-intanethi.
Ukukhuseleka kweeNgcaciso zeNgcaciso (Wireless Transaction Layer) (WTLS) inikezela ukuqinisekiswa kunye nokusebenza kwemfihlo ngokufana neSecott Sockets Layer (SSL) kwiwebhsayithi. Njengesi-SSL, i-WTLS iyakhethwa kwaye iyasetyenziswa kuphela xa iseva yomxholo ifuna yona.
I-Wireless Datagram Protocol (WDP) isebenzisa isalathisi esingenanto kwiiprotokholi zenethiwekhi eziphantsi. yenza imisebenzi efana ne-UDP. I-WDP yinkalo engezantsi yekhowudi ye-WAP, kodwa ayisebenzisi ukuxhunywa komzimba okanye idatha yonxibelelwano. Ukwakha inkonzo enxibelelwano epheleleyo, i-WAP stack kufuneka iphunyezwe kwiprogram engumgangatho ophantsi welifa eliqhelekileyo kungekhona inxalenye yesimo. Ezi mpahla, ezibizwa ngokuba ziinkonzo zenkampani okanye abaphathi , zinokusetyenziswa kwi-IP okanye ngaphandle kwe-IP.
