Dzina lakuti WAP limakhala ndi matanthauzo awiri osiyanasiyana pa malo osungira mauthenga opanda waya. WAP imayimira onse opanda Wire Point Access ndi Wireless Application Protocol .
Zosakaniza Zopanda Zapanda
Malo osayendetsedwa opanda waya ndi chipangizo chomwe chimagwirizanitsa opanda waya (kawirikawiri Wi-Fi ) makanema amtunduwu kuntaneti (wamba Ethernet ).
Kuti mudziwe zambiri, onani - Kodi ndizitani zopanda pakompyuta?
Foni ya M'manja
The Wireless Application Protocol inasankhidwa kuti zithandizire zokhudzana zopereka kwa mafoni apamwamba pa mawotchi opanda waya. Choyambira pa mapangidwe a WAP chinali chingwe chogwiritsira ntchito pulogalamu ya OSI . WAP ikugwiritsa ntchito mauthenga angapo atsopano a mauthenga omwe amagwira ntchito mofananako koma akusiyana ndi mapulogalamu odziwika bwino a pa intaneti a HTTP , TCP , ndi SSL .
WAP ikuphatikizapo malingaliro a ma browser, ma seva , ma URL , ndi makanema a makanema . Mawindo oyendetsa makompyuta anakhazikitsidwa kuti apange zipangizo zam'nyanja monga mafoni, pagers, ndi PDA. M'malo mokhala ndi zokhudzana ndi HTML ndi JavaScript, oyambitsa WAP amagwiritsa ntchito WML ndi WMLScript. Kukanikizidwa pa ma intaneti akuyenda mofulumira ndikugwiritsira ntchito mphamvu zamakono, WAP inathandiza kokha kachigawo kakang'ono ka ntchito za PC. Zochita zamtunduwu zamakono zinali zowonjezera zamabuku, zolemba zamagulu, ndi mauthenga.
Ngakhale kuti zipangizo zamakono zopezeka pa WAP zinakhalapo pamsika kuyambira 1999 mpaka pakati pa zaka za 2000, sizinatengere nthawi yambiri kuti zipangizo zamakono zisinthe ndi zipangizo zamakono zamakono ndi mafoni a m'manja.
The WAP Model
Pulogalamu ya WAP imakhala ndi zigawo zisanu mukhola, kuyambira pamwamba mpaka pansi: Kugwiritsa ntchito, Gawo, Kugulitsa, Chitetezo ndi Transport.
Pulogalamu yamakono ya WAP ndiyo Wireless Application Environment (WAE). WAE mwachindunji akuthandizira chitukuko cha Pulogalamu ya WAP ndi Chilankhulo cha Wireless Markup (WML) m'malo mwa HTML ndi WMLScript mmalo mwa JavaScript. WAE imaphatikizapo mawonekedwe a Wireless Telephony Application (WTAI, kapena WTA mwachidule) omwe amapereka mawonekedwe a pulogalamu kwa matelefoni poyitana mafoni, kutumiza mauthenga, ndi mauthenga ena.
Pulogalamu yamakono ya WAP ndiyo Wireless Session Protocol (WSP). WSP ndi ofanana ndi HTTP kwa WAP osatsegula. WAP ikuphatikiza ma browser ndi ma seva monga Webusaiti, koma HTTP siinali yabwino pa WAP chifukwa cha kusagwirizana kwake pa waya. WSP imateteza mawonekedwe ofunika kwambiri pa maulumikiza opanda waya; makamaka, WSP ikugwira ntchito ndi deta yosakanikirana komwe HTTP imagwira ntchito makamaka ndi malemba.
Wireless Transaction Protocol (WTP) imapereka chithandizo chamagulu pazinthu zodalirika komanso zosakhulupirika. Imalepheretsa mapepala awiri kuti asalandireko, ndipo imathandizira kubwezeretsanso, ngati kuli kofunikira, panthawi imene mapaketi ataya. Pankhani imeneyi, WTP ikufanana ndi TCP. Komabe, WTP imasiyananso ndi TCP. WTP kwenikweni ndi TCP yochepetsedwa pansi yomwe imapangitsa ntchito zina zoonjezera kuchokera pa intaneti.
Wireless Transaction Layer Security (WTLS) imapereka chitsimikizo ndi kufotokozera zofanana zomwe zimagwirizana ndi Security Sockets Layer (SSL) pa intaneti. Monga SSL, WTLS ndi yokhayokha ndipo imagwiritsidwa ntchito pamene seva yokhutira ikufunika.
Wopanda Datagram Protocol (WDP) amagwiritsa ntchito zosanjikizira pazitsulo zamtundu wotsika; imachita ntchito yofanana ndi UDP. WDP ndi gawo la pansi la WAP, koma silikugwiritsira ntchito chiyanjano cha thupi kapena deta. Kuti mupange utumiki wokhudzana ndi intaneti, pulogalamu ya WAP imayenera kukhazikitsidwa pazithunzi zochepa zomwe sizingagwiritsidwe ntchito. Mapulogalamu awa, otchedwa mautumiki othandizira kapena othandizira , akhoza kukhala IP-based kapena osakhala a IP.
