Sikumema ukuba wazi Izinzuzo nobubi be-mesh topology, Uchungechunge lwezinto ezisiza ekudluliseni nasekuxhumaneni kwedatha phakathi kwamakhompyutha. Kuyindatshana ethokozisayo engaba wusizo kakhulu kubo bonke abasebenzisi abanolwazi besifundo.
Izinzuzo nobubi be-mesh topology
I-mesh network topology, ingenye lapho ngayinye ine-node exhunywe kuwo wonke ama-node, kuyindlela yokwenza ukuthi imilayezo idluliselwe isuka komunye nomunye ngezindlela ezahlukahlukene.
Manje, uma inethiwekhi enezikhala ixhumeke ngokuphelele ngokuphepha, ngeke zibe khona izingqinamba zokuxhumana, iseva ngayinye inokuxhumana kwayo namanye amaseva.
Ukusungulwa kwenethiwekhi enezikhala kuyindlela engcono yokuhambisa imininingwane, izwi nemiyalo phakathi kwezindawo, lawa manethiwekhi ahlukaniswa namanye amanethiwekhi ngoba izingxenye zenethiwekhi, okungukuthi, ama-node, zixhunywe komunye nomunye ngezintambo ezihlukene.
Ukucushwa okunikeza imizila ephindaphindwayo kuyo yonke inethiwekhi, okusho ukuthi esimweni lapho kukhona ukwehluleka kukhebuli eyodwa, enye yazo izobhekana nomgwaqo.
I-topology ye-mesh ihlukaniswe neminye efana ne-topology yesihlahla ne-topology yezinkanyezi, ngoba ayidingi iseva emaphakathi, ukunciphisa ukugcinwa, kufanele kwaziwe ukuthi ukwehluleka kwe-node kungadala ukwehluleka okuphelele kwenethiwekhi.
Sincoma lokhu okuthunyelwe okungakusiza kakhulu Izinhlobo ze-topologies yenethiwekhi nezici zazo.
Amanethiwekhi we-Mesh anesici sokuthi ayazilawula, angasebenza noma ngabe kwenzeka ukuthi i-node inyamalale noma ukuxhumeka kuphonsa ukwehluleka, konke kungenxa yokuthi amanye ama-node avimbela ukudlula, ngakho-ke inethiwekhi ye-mesh iba inethiwekhi inokwethenjelwa ngokuphelele.
I-topology ye-mesh wuhlobo lwenethiwekhi oluholela ekuxhumaneni kwenombolo enkulu yama-node, futhi ngayinye yalezi zixhunyaniswe ngqo nezinye, ukuze yonke imishini exhunywe kule nethiwekhi ihlale ixhunyaniswa njalo. Kuyiphuzu elibaluleke kakhulu, ukuhamba kwedatha kuzohlala kungaguquguquki ukufinyelela wonke amatheminali.
I-topology ye-mesh uhlobo lwenethiwekhi olunikeza izinzuzo nezinkinga njengoba kushiwo ngezansi:
Izinzuzo
I-topology yemeshini inikeza izinzuzo eziningi, ezihlose ukwanelisa izidingo zabasebenzisi bazo, kubalulekile ukuzenza zaziwe:
- Inikeza ukuthembeka okukhulu.
- Iyamelana nobunzima noma ukwehluleka, okungukuthi, ingasebenza lapho kubhekene nobunzima.
- Uma kwenzeka ukuthi ezinye zezinto ezinhle zivelisa ukwehluleka, i-topology enezikhala ihlala isebenza ngokuhambisana nezinye ezikhona ezisenethiwekhi.
- Inezixhumanisi eziningi, uma kwenzeka ukuthi kuvinjwe umzila owodwa, enye ingafakwa ukuxhumana nedatha.
- Ukwehluleka okwethulwe kudivayisi akukwenzi ukuphazamiseka ekudlulisweni kwedatha noma kunethiwekhi.
- Kulula futhi kuyasebenziseka ukuthola nokuhlonza noma yikuphi ukwehluleka ngenxa yokuxhumeka kwephoyinti nephoyinti.
- Ngokufaka noma ukususa noma iyiphi idivayisi, inqubo ayiphazamisi ukudluliswa kwedatha okuqhubekayo ngamanye amadivayisi.
- Azikho izinkinga zethrafikhi, ngoba kunamadivayisi amaningi angadlulisa imininingwane ngasikhathi sinye, kukhona nezixhumanisi ezinikezelwe ngamaphuzu akhomba kukhompyutha ngayinye.
- Inikeza ubumfihlo nokuphepha.
- Ukwehla okulula, okusho ukuthi i-node ngayinye ingasebenza njenge-router, ngakho-ke awudingi ukufaka amanye ama-routers, okusho ukuthi usayizi wenethiwekhi ungashintshwa kalula futhi ngokushesha.
- Ukuqiniseka kwezokuxhumana ngendlela ephazanyisiwe nawo wonke amakhompyutha axhunyiwe.
- Ubukhona bezindlela ezahlukahlukene zokushintshanisa idatha.
- Ukuhamba kolwazi akunamkhawulo.
- Lapho kunephutha emgwaqeni, zonke zizoqhubeka nokusebenza.
- Inikeza ukuphepha kubasebenzisi, ngoba inqubo yokuxhumana izoqhubeka.
- Imininingwane itholakala unomphela.
- Ukuba khona kwezinye iziteshi zokuxhumana ukuletha idatha kumsebenzisi, uma kwenzeka ukwehluleka kokuxhumeka kunemiphumela emibi.
- Inikeza ukuzinza ngaso sonke isikhathi, ukuxhumana akuhlali njalo.
- Uma kwenzeka ukwehluleka kwekhebula, okusele kuzothatha ithrafikhi yolwazi.
- Ikhompyutha ngayinye inezindlela zayo zokuxhuma namanye amadivayisi akha inqubo.
- Ukusetshenziswa kwe-topology enezikhala kunenzuzo enkulu ngokwesimo sezomnotho, kunikeza ukonga okukhulu ikakhulukazi ekugcinweni kwayo.
- Ayinayo i-node emaphakathi, enenzuzo uma kwenzeka ukwehluleka kweseva; yonke inethiwekhi ngeke kudingeke ilungiswe ngokuphelele.
- Inikeza ukusebenza kahle, ukuzethemba nejubane lapho wenza ukushintshana kwedatha.
nebubi
Yize lolu hlobo lwenethiwekhi luphakathi kokunconywa kakhulu, akuphephile ukuthi kukhona ukungalungi okuthile okumbalwa kulo lonke, ake sibheke:
- Inani lalo lingabonakala likhula esimweni sokusebenzisa imodi engenantambo.
- Kudinga izinsizakusebenza eziningi ukuze zifaneleke njengesiteshi sokuxhumana esisebenzayo.
- Izindleko zesondlo zingaba phezulu.
- Ukucushwa kokuqala kuyinkimbinkimbi, okusho ukuthi, ukusebenzisa le nethiwekhi kusukela ekuqaleni kuthatha isikhathi esithe xaxa kunokulungiselela okwendabuko.
- Ukulayishwa okuphezulu komsebenzi kusho ukuthi idivaysi ayisebenzi nje kuphela njenge-router, kodwa futhi inesibopho sokuthumela idatha.
- I-Mesh topology iyabiza, ngoba idinga amakhebuli amaningi namachweba we-I / O.
- Ukusetshenziswa kwamandla okuphezulu, uma i-node ngayinye iqala ukusebenza njengendawo yokuphela futhi njengomzila, umthwalo womsebenzi uyanda futhi udale ukungezwani. I-node ngayinye idinga amandla amaningi ukuze isebenze kahle.
- Uma kwenzeka okokusebenza kukhulu futhi kuxhunywe ngqo ohlelweni lukagesi, kungadala inkinga, okufanayo kungenzeka kumadivayisi amancane asebenza ngamabhethri ekugcineni angaveza ukwehluleka.
Izici
I-topology yemesh inezici ezithile ezibalulekile ukuzazi, phakathi kwazo okushiwo:
- Kungahanjiswa noma kube nezikhukhula.
- Lapho idatha ihanjisiwe kunethiwekhi, iyandiswa ngesikhombisi esichazwe ngaphambilini, esisuka kudivayisi eyodwa siye kwesinye, ukuze kufinyelelwe kudivayisi ekhonjiwe.
- Isebenza unomphela ngokusesha izindlela ezingalungile futhi ikhiqize ama-algorithm wokuzilungisa ukuze wakhe amatafula wedatha.
- Isimo sesikhukhula somgwaqo sihamba kuyo yonke inethiwekhi ngendlela engaguquguquki, uma nje idivayisi ithole ukuthi idatha iphethe ikheli layo, iyazithathela yona.
