Siyakumema ukuba wazi Izibonelelo kunye nezinto ezingalunganga zetopologyKuluhlu lwezinto ezinceda ukuhambisa kunye nokunxibelelana kwedatha phakathi kweekhompyuter. Inqaku elinomdla elinokuba luncedo kubo bonke abasebenzisi abanolwazi besifundo.
Izibonelelo kunye nezinto ezingalunganga zetopology
I-topology yenethiwekhi enemingxunya, yenye apho nganye nganye inedode exhunywe kuzo zonke iindawo, yindlela yokwenza ukuba imiyalezo idluliselwe ukusuka kwenye ukuya kwenye ngeendlela ezahlukeneyo.
Ngoku, ukuba umnatha womnatha uqhagamshelwe ngokukhuselekileyo, akusayi kubakho zithintelo zonxibelelwano, iserver nganye inonxibelelwano lwayo kunye nezinye iiseva.
Ukusekwa kothungelwano lwe-mesh yeyona ndlela yokuhambisa ulwazi, ilizwi kunye nemiyalelo phakathi kweendawo, ezi nethiwekhi zahlukile kwezinye iinethiwekhi kuba izinto zenethiwekhi, oko kukuthi, iindawo, zidityanisiwe kwenye ngeentambo ezahlukeneyo.
Luqwalaselo olunikezela iindlela eziphindaphindwayo kuyo yonke inethiwekhi, oko kuthetha ukuba kwimeko apho kukho ukusilela kwintambo enye, enye yazo iya kuthatha uxanduva lwezithuthi.
I-topology ye-mesh yahlukile kwezinye ezinje nge-topology yomthi kunye ne-topology yeenkwenkwezi, kuba ayifuni iseva esembindini, ukunciphisa ukugcinwa, kufanelekile ukuba yaziwe ukuba ukusilela kwe-node kunokubangela ukusilela ngokupheleleyo kwenethiwekhi.
Sincoma esi sithuba esinokukuxhasa kakhulu Iindidi zeetopiki zenethiwekhi kunye neempawu zazo.
Uthungelwano lwe-Mesh lunophawu lokuba luyazilawula, lunokusebenza nokuba kunokwenzeka ukuba indawo inyamalale okanye uqhagamshelo luphose ukusilela, yonke into ibangelwa yinto yokuba ezinye iindawo zithintela indawo, ke umnatha womnatha uba inethiwekhi inokuthenjwa ngokupheleleyo.
I-topology ye-mesh luhlobo lwenethiwekhi ekhokelela kunxibelelwano lwenani elikhulu leendawo, kwaye nganye yezi inxibelelene ngokuthe ngqo nezinye, ukuze zonke izixhobo ezinxibelelene nale nethiwekhi ziya kuhlala zinxibelelana. Ingongoma ebaluleke kakhulu, ukuhamba kwedatha kuya kuhlala kunjalo ukufikelela kuzo zonke iitheminali.
I-topology ye-mesh luhlobo lwenethiwekhi enika izibonelelo kunye nezinto ezingalunganga njengoko kuchaziwe apha ngezantsi:
Inzuzo
I-topology ye-mesh ibonelela ngeendlela ezahlukeneyo, ezijolise ekwaneliseni iimfuno zabasebenzisi, kubalulekile ukuzazisa:
- Inika ukuthembeka okukhulu.
- Iyaxhathisa kubunzima okanye ukusilela, oko kukuthi, inokusebenza ebusweni bayo nayiphi na ingxaki.
- Kwimeko apho izinto ezithile ezintle zivelisa ukungaphumeleli, i-topology ye-mesh ihlala isebenza ngokuhambelana nezinye ezikhoyo ezikhoyo kwinethiwekhi.
- Inamakhonkco amaninzi, kwimeko apho indlela enye ivaliwe, enye inokufakwa ukunxibelelana nedatha.
- Ukusilela okuboniswe kwisixhobo akuvelisi ukuphazamiseka kudluliso lwedatha okanye kwinethiwekhi.
- Kulula kwaye kuyenzeka ukufumanisa nokuchonga nakuphi na ukusilela ngenxa yokunxibelelana kwenqaku nendawo.
- Ngokudibanisa okanye ukususa nasiphi na isixhobo, inkqubo ayiphazamisi ukuhanjiswa kwedatha okuqhubekayo ngezinye izixhobo.
- Akukho zingxaki zendlela, kuba kukho izixhobo ezininzi ezinokuhambisa idatha ngaxeshanye, kukwakho nokunikezelwa kwamakhonkco okwi-point-to-point kwikhompyuter nganye.
- Inika ubumfihlo nokhuseleko.
- Ukuma ngokulula, okuthetha ukuba node nganye inokusebenza njenge-router, ke awudingi ukufaka ezinye iirouters, oko kuthetha ukuba ubungakanani benethiwekhi bunokutshintshwa ngokulula nangokukhawuleza.
- Ukuqiniseka kunxibelelwano ngendlela ephazamisekileyo kunye nazo zonke iikhompyuter ezixhumeneyo.
- Ubukho beendlela ezahlukeneyo zokutshintsha idatha.
- Ukuhamba kolwazi akunamda.
- Xa kukho nasiphi na isiphoso endleleni, zonke ziya kuqhubeka nokusebenza.
- Inika ukhuseleko kubasebenzisi, kuba inkqubo yonxibelelwano iya kuqhubeka.
- Ulwazi lufumaneka ngokusisigxina.
- Ubukho bezinye iindlela zonxibelelwano zokuhambisa idatha kumsebenzisi, kwimeko yokusilela konxibelelwano kunye neziphumo ezibi.
- Inika uzinzo ngalo lonke ixesha, unxibelelwano luhlala luhleli.
- Kwimeko apho kukho ukusilela kwentambo, okuseleyo kuya kuthatha ingcaciso yezithuthi.
- Ikhompyuter nganye ineendlela zayo zonxibelelwano kunye nezinye izixhobo ezenza inkqubo.
- Ukusetyenziswa kwetopology enemingxunya kunenzuzo ngakumbi ngokwemiba yezoqoqosho, ibonelela ngolondolozo olukhulu ngakumbi kulondolozo lwayo.
- Ayinayo indawo engumbindi, ethi izuze kwimeko yokusilela kweseva; yonke inethiwekhi ayizukulungiswa ngokupheleleyo.
- Inika ukusebenza ngokukuko, ukuzithemba kunye nesantya xa kusenziwa unaniselwano ngedatha.
Iingxaki
Nangona olu hlobo lwenethiwekhi luphakathi kwezona zicetyiswayo, akukhuselekanga ukuba kukho iziphene ezithile ezimbalwa kulo lonke, masibone:
- Ixabiso laso linokubonwa lisanda kwimeko yokusebenzisa imowudi engenazingcingo.
- Ifuna izixhobo ezininzi ukuze ifaneleke njengejelo lonxibelelwano elisebenzayo.
- Iindleko zolondolozo zingaba phezulu.
- Ukucwangciswa kokuqala kuyinkimbinkimbi, oko kukuthi, kuthatha ixesha elide ukuphumeza le nethiwekhi ukususela ekuqaleni kunokumisela imveli.
- Umthwalo ophezulu womsebenzi uthetha ukuba isixhobo asisebenzi njenge-router kuphela, kodwa sinoxanduva lokuthumela idatha.
- I-topology ye-Mesh iyabiza, kuba ifuna iintambo ezininzi kunye namazibuko e-I / O.
- Ukusetyenziswa kwamandla amakhulu, nje ukuba i-node nganye iqale ukusebenza njengendawo yokuphela kunye nendlela, umthwalo womsebenzi uyonyusa kwaye uvelise uxinzelelo. I-node nganye ifuna amandla angakumbi ukuze isebenze kakuhle.
- Kwimeko apho izixhobo zikhulu kwaye zidityaniswe ngqo kwinkqubo yombane, kunokubangela ingxaki, kuya kwenzeka okufanayo kwizixhobo ezincinci ezisebenza ngeebhetri ekugqibeleni zinokubonisa ukusilela.
Izixhobo
I-topology ye-mesh ineempawu ezithile kubalulekile ukuzazi, phakathi kwazo zikhankanyiweyo:
- Inokuhanjiswa okanye ukugcwala kwezithuthi.
- Nje ukuba idatha ihanjiswe kuthungelwano, iyandiswa ngumgaqo ochazwe ngaphambili, ovela kwisixhobo esinye uye kwesinye, ukuze ufikelele kwisixhobo ekujoliswe kuso.
- Isebenza ngokusisigxina kwiindlela ezingalunganga kwaye ivelise ii-algorithms zokuzilungisa ngokwakho ukwenza iitafile zedatha.
- Umkhukula wendlela ohamba kuyo yonke inethiwekhi ngendlela engagungqiyo, nje ukuba isixhobo sibone ukuba idatha iphethe idilesi yayo, iyazithathela yona.
