Mungafunike kudziwa kuti OSI Model 7 Layers ndi chiyani?
Tisanalowe mu chitsanzo cha OSI, tiyenera kumvetsetsa mawu oyambira olumikizirana kuti tithe kukambirana motere.
Ma Node
Node ndi chipangizo chilichonse chamagetsi cholumikizidwa ku netiweki, monga kompyuta, chosindikizira, rauta, ndi zina zotero. Node zimatha kulumikizidwa kuti zipange netiweki.
Ulalo
Ulalo ndi kulumikizana kwachilengedwe kapena kwanzeru komwe kumalumikiza ma node mu netiweki, komwe kungakhale ndi waya (monga Ethernet) kapena opanda waya (monga WiFi) ndipo kumatha kukhala mfundo imodzi kapena zingapo.
Ndondomeko
Ndondomeko ndi lamulo la ma node awiri mu netiweki kuti asinthane deta. Malamulo awa amafotokoza kalembedwe, tanthauzo, ndi kulunzanitsa kusamutsa deta.
Netiweki
Netiweki imatanthauza gulu la zipangizo, monga makompyuta, ma printers, zomwe zimapangidwa kuti zigawire deta.
Topology
Topology imafotokoza momwe ma node ndi maulalo amakhazikitsidwira mu netiweki ndipo ndi gawo lofunikira pa kapangidwe ka netiweki.
Kodi chitsanzo cha OSI ndi chiyani?
Chitsanzo cha OSI (Open Systems Interconnection) chimafotokozedwa ndi International Organization for Standardization (ISO) ndipo chimagawa maukonde apakompyuta m'magawo asanu ndi awiri kuti athandize kulumikizana pakati pa machitidwe osiyanasiyana. Chitsanzo cha OSI chimapereka kapangidwe kokhazikika ka kapangidwe ka netiweki, kuti zipangizo zochokera kwa opanga osiyanasiyana zitha kulankhulana.
Zigawo zisanu ndi ziwiri za chitsanzo cha OSI
1. Gawo Lakuthupi
Udindo wotumiza mitsinje yamagetsi yopanda kanthu, umatanthauzira makhalidwe a zolumikizira zakuthupi monga zingwe ndi zizindikiro zopanda waya. Deta imatumizidwa mu ma bits pagawo ili.
2. Gawo la Ulalo wa Deta
Mafelemu a deta amatumizidwa kudzera pa chizindikiro chenicheni ndipo ali ndi udindo wozindikira zolakwika ndi kuwongolera kayendedwe ka deta. Deta imakonzedwa m'mafelemu.
3. Gulu la Netiweki
Ili ndi udindo wonyamula mapaketi pakati pa ma network awiri kapena kuposerapo, kusamalira njira zolumikizirana ndi ma adilesi olondola. Deta imakonzedwa m'mapaketi.
4. Gawo Loyendera
Imapereka deta yotumizidwa kuchokera kumapeto mpaka kumapeto, kuonetsetsa kuti deta ndi yolondola komanso yotsatizana, kuphatikizapo protocol yolunjika yolumikizidwa ndi TCP ndi protocol yopanda kulumikizana ndi UDP. Deta ili mu mayunitsi a magawo (TCP) kapena ma datagram (UDP).
5. Gawo la Gawo
Kusamalira magawo pakati pa mapulogalamu, omwe ali ndi udindo wokhazikitsa, kukonza, ndi kuthetsa magawo.
6. Gawo Lowonetsera
Kusamalira kusintha kwa mawonekedwe a deta, kuyika zilembo, ndi kubisa deta kuti muwonetsetse kuti detayo ingagwiritsidwe ntchito moyenera ndi gulu la pulogalamu.
7. Gawo Logwiritsira Ntchito
Imapatsa ogwiritsa ntchito mautumiki apaintaneti mwachindunji, kuphatikiza mapulogalamu ndi mautumiki osiyanasiyana, monga HTTP, FTP, SMTP, ndi zina zotero.
Cholinga cha gawo lililonse la chitsanzo cha OSI ndi mavuto ake omwe angakhalepo
Gawo 1: Gawo Lathupi
Cholinga: Gawo lakuthupi limakhudzana ndi makhalidwe a zipangizo zonse zakuthupi ndi zizindikiro. Lili ndi udindo wopanga ndikusunga kulumikizana kwenikweni pakati pa zipangizo.
Kusaka zolakwika:
○Yang'anani ngati zingwe ndi zolumikizira zawonongeka.
○Onetsetsani kuti zipangizo zakuthupi zikugwira ntchito bwino.
○Tsimikizani kuti magetsi ndi abwinobwino.
Gawo 2: Gawo la Ulalo wa Deta
Cholinga: Gawo lolumikizira deta lili pamwamba pa gawo lenileni ndipo limayang'anira kupanga chimango ndi kuzindikira zolakwika.
Kusaka zolakwika:
○Mavuto omwe angakhalepo pa gawo loyamba.
○Kulephera kwa kulumikizana pakati pa ma node.
○Kuchulukana kwa maukonde kapena kugundana kwa chimango.
Gawo 3: Gawo la Netiweki
Cholinga: Gawo la netiweki limayang'anira kutumiza mapaketi ku adilesi yopitako, kusamalira kusankha njira.
Kusaka zolakwika:
○Onetsetsani kuti ma routers ndi ma switch akonzedwa bwino.
○Onetsetsani kuti adilesi ya IP yakonzedwa bwino.
○Zolakwika za ulalo wa ma link zingakhudze momwe layer iyi imagwirira ntchito.
Gawo 4: Gawo Loyendera
Cholinga: Gawo loyendera limatsimikizira kutumiza deta modalirika komanso kusamalira kugawa ndi kukonzanso deta.
Kusaka zolakwika:
○Tsimikizani kuti satifiketi (monga SSL/TLS) yatha ntchito.
○Onani ngati chotetezera moto chatseka doko lofunikira.
○Kufunika kwa magalimoto kumakhazikitsidwa bwino.
Gawo 5: Gawo la Gawo
Cholinga: Gawo la gawoli lili ndi udindo wokhazikitsa, kusunga ndi kuthetsa magawo kuti zitsimikizire kusamutsa deta mbali zonse ziwiri.
Kusaka zolakwika:
○Chongani momwe seva ilili.
○Tsimikizani kuti kasinthidwe ka pulogalamuyo ndi kolondola.
○Magawo akhoza kutha nthawi kapena kutha.
Gawo 6: Gawo Lowonetsera
Cholinga: Gawo lowonetsera limagwira ntchito yokhudza nkhani za kapangidwe ka deta, kuphatikizapo kubisa ndi kuchotsa kubisa.
Kusaka zolakwika:
○Kodi pali vuto ndi dalaivala kapena pulogalamu?
○Kaya mtundu wa deta wasankhidwa bwino.
Gawo 7: Gawo Logwiritsira Ntchito
Cholinga: Gawo la pulogalamu limapereka ntchito zogwiritsira ntchito mwachindunji ndipo mapulogalamu osiyanasiyana amayendetsedwa pa gawoli.
Kusaka zolakwika:
○Pulogalamuyi yakonzedwa bwino.
○Kaya wogwiritsa ntchitoyo akutsatira njira yoyenera.
Kusiyana kwa TCP/IP ndi OSI
Ngakhale kuti chitsanzo cha OSI ndiye muyezo wolankhulirana ndi maukonde, chitsanzo cha TCP/IP ndiye muyezo wa maukonde womwe umagwiritsidwa ntchito kwambiri. Chitsanzo cha TCP/IP chimagwiritsa ntchito kapangidwe ka hierarchical, koma chili ndi zigawo zinayi zokha (application layer, transport layer, network layer, ndi link layer), zomwe zimagwirizana motere:
Chigawo cha pulogalamu ya OSI <--> Chigawo cha pulogalamu ya TCP/IP
Gawo loyendetsa la OSI <--> Gawo loyendetsa la TCP/IP
Chigawo cha netiweki cha OSI <--> Chigawo cha netiweki cha TCP/IP
Gawo la ulalo wa data la OSI ndi gawo lenileni <--> gawo la ulalo wa TCP/IP
Kotero, chitsanzo cha OSI cha magawo asanu ndi awiri chimapereka chitsogozo chofunikira pakugwirizanitsa zida ndi machitidwe a netiweki pogawa momveka bwino mbali zonse za kulumikizana kwa netiweki. Kumvetsetsa chitsanzo ichi sikungothandiza oyang'anira ma netiweki kuthetsa mavuto, komanso kumayala maziko a kafukufuku ndi kafukufuku wozama wa ukadaulo wa netiweki. Ndikukhulupirira kuti kudzera mu mawu oyamba awa, mutha kumvetsetsa ndikugwiritsa ntchito chitsanzo cha OSI mozama kwambiri.
