Izwi rokuti WAP rine zvinyorwa zviviri zvakasiyana munyika ye wireless networking. WAP inomirira zvose Wireless Access Point uye Wireless Application Protocol .
Wireless Access Points
A wireless access point iyo inogadzirisa wireless (kazhinji Wi-Fi ) inzvimbo yekambani kune wired (kazhinji Ethernet ) network.
Kuti uwane mamwe mashoko, tarisa- Chii chine wireless access points?
Wireless Application Protocol
The Wireless Application Protocol yakatsanangurwa kutsigira zvinyorwa zvinotengeswa kune zvigadzirwa zvemagetsi pamusoro pemagetsi asingatauri. Pakati pekugadzirwa kweP WAP yakanga yakagadzirwa nehutachiona yakagadzirwa nemuenzaniso weOSI . WAP yakaita mitauro yakawanda mitauro inoshandiswa iyo inoita mabasa akafanana asi asi yakasiyana nemitambo inozivikanwa yeWeb HTTP , TCP , uye SSL .
WAP yakabatanidza pfungwa dzevashandisi, sevhisi , URLs , uye network gateways . WAP browsers yakagadzirwa nemasikirusi emafoni mashoma akadai sefoni, pagers, uye PDAs. Panzvimbo yekuvandudza zvinyorwa mu HTML neJavaScript, vashandisi ve WAP vakashandisa WML neWMLScript. Kudzivirirwa pazvinhu zviviri zvekutengesa mitambo uye kushandiswa kwesimba kwezvigadzirwa, WAP yakatsigira kambani kadiki kadiki yemashandisi ePC. Zvinyorwa zvekushandiswa kwekombiyuta iyi yaiva nhepfenyuro dzemashoko, zvinyorwa zvinyorwa, uye mameseji.
Kunyange zvazvo nhamba yakanaka yezvikomborero zvakagadzirwa neW WAP zvaive mumusika kubva muna 1999 kusvika pakati pe2000, hazvina kutora kwenguva refu kuti teknolojia ive isina kushandiswa nekuvandudzika kwekombiki yepamusoro ekutengesa mafoni uye mafoni.
The WAP Model
I-WAP model inosanganisira zvikamu zvishanu mumutsetse, kubva kumusoro kusvikira pasi: Kuita, Session, Transaction, Security uye Transport.
WAP's application layer ndiyo Wireless Application Environment (WAE). WEMWE anonyatsotsigira kukura kwekushandisa kweW WAP ne Wireless Markup Mutauro (WML) panzvimbo ye HTML neWMLScript panzvimbo ye JavaScript. WAE inosanganisirawo Wireless Telephony Application Interface (WTAI, kana WTA kwenguva pfupi) iyo inopa purogiramu yepurogiramu kumapurofoni ekutanga foni, kutumira mameseji, uye mamwe maitiro ekubatanidza.
WAP's session layer ndiyo Wireless Session Protocol (WSP). WSP ndiyo yakaenzana neHTTP yeWeb browsers. WAP inosanganisira browsers nes server seWebhu, asi HTTP yakanga isiri sarudzo yakakodzera ye WAP nemhaka yekusakosha kwayo kwetambo. WSP inochengetedza bandwidth inokosha kune wireless links; kunyanya, WSP inoshanda nemabhadhadziro akawandisa emunharaunda umo HTTP inonyanya kushanda nemashoko ekunyora.
Wireless Transaction Protocol (WTP) inopa rubatsiro rwekutengeserana-yepamusoro kwekutendeseka uye kutendeseka. Inodzivirira mapepa emapepa kubva pakagamuchirwa nechinzvimbo, uye inobatsira kudzorerazve, kana zvichidikanwa, mumamiriro ezvinhu apo mapaketi anodonhedzwa. Munyaya iyi, WTP yakafanana neTCP. Zvisinei, WTP yakasiyanawo neTCP. WTP inonyanya kushandiswa-pasi pasi yeTCP iyo inopedza mamwe maitiro ekuwedzera kubva kunhare.
Wireless Transaction Layer Security (WTLS) inopa kuvimbiswa uye kuvharidzira kushanda kunoenderana neSecure Sockets Layer (SSL) muWeb network. Kufanana neSSSL, WTLS inosarudzwa uye inoshandiswa chete kana zvinyorwa zvinodiwa zvinoda.
Wireless Datagram Protocol (WDP) inoshandisa imwe nzvimbo yepamusoro kune zvikamu zvepasi-pasi mitambo; inoita mabasa akafanana neDPP. WDP ndiyo inoperera pasi yePACK stack, asi haisi kushandisa mamiriro ekugadzira muviri kana data. Kuti uvakire zvakakwana network network service, iyo WAP stack inofanira kushandiswa pane imwe nzvimbo yakaderera yefaji yekodzero kwete chetsika chikamu chemuenzaniso. Izvi zvinopindirana, zvinonzi vashandi vekutakura kana vatakuri , zvinogona kuva IP-based kana kwete IP based.
