Imizila ihlukaniswa yaba izinhlobo ezintathu: umzila omile, umzila oguquguqukayo, nomzila oqondile.
Endleleni yokufaka umzila omile owenziwe ngesandla, ukuze kuxazululwe inkinga yomzila wawo wonke umhlaba we-ip, ibuthakathaka kakhulu eqinisweni.
Ngakho-ke, ochwepheshe bacabanga ukuvumela umzila ovela ekhaya, utshele umzila oseduze, ukuthi ngingubani eduze kwakhe, ukuthi ngingubani eduze kwakhe, ukuze ngemva kokuqedwa kombuthano, itafula lomzila liyatholakala, ngokusekelwe kulesi simiso, umzila oguqukayo uyakhiqizwa.
Iphrothokholi elula kakhulu yomzila ibizwa nge-RIP, ebizwa ngokuthi “i-distance vector protocol”, futhi okwamanje sisebenzisa inguqulo yayo ethuthukisiwe i-RIP2. Uma sithi iphrothokholi yomzila ilula noma inkimbinkimbi, enye yezindlela zokunquma ubunkimbinkimbi be-algorithm "yezindleko ezibanzi zomzila" ebalulwe umthetho olandelwayo womzila, futhi i-algorithm yezindleko zendlela ye-RIP2 iyona elula kakhulu.
Ku-RIP2, amarutha athumela lokho okubizwa ngokuthi “i-vector yebanga” kumarutha angomakhelwane njalo ngemizuzwana engama-30, futhi itafula lomzila ligcina kuphela ikheli le-hop elilandelayo lendlela engcono kakhulu eya endaweni okuyiwa kuyo. I-RIP2 Ikhetha indlela engcono kakhulu ngokusekelwe ekubalweni kwe-router hop encane. Isibonelo, kunezindlela ezimbili phakathi kwerutha A nerutha B. Umzila owodwa udlula kumarutha ayi-10 kanti omunye udlula amarutha angu-8. I-RIP2 inquma ukuthi iphakethe le-ip ku-A kufanele lidlule emzileni wesibili ukuze lifinyelele umzila B
I-RIP2 ivumela ubuningi be-hops engu-15. Ama-hop angaphezu kuka-15 athathwa njengokungafinyeleleki. Iphrothokholi entsha ye-RIP esekelwe ku-ipv6 i-RIPng ithuthukise ifomethi yolwazi nezici ezihlobene namakheli kune-RIP2.
Ubulula buwukuqina kanye nobuthakathaka. Kunethiwekhi enkulu ye-IP, ukuthembela kuphela enanini lama-hops le pharamitha yebanga ukukhetha umzila, ezimweni eziningi kuzoba wumsebenzi omncane. Esibonelweni esifanayo, i-router A ifika kumzila we-router B enenani elibonakala lilikhulu lama-hops, kodwa uma umkhawulokudonsa mkhulu kakhulu kunalowo wendlela yesi-2, i-RIP2 izokwenzani?
I-RIP2 isazokhetha ngenkani indlela yesi-2. Futhi empeleni, indlela yesi-2 ayilungile. Ngakho-ke, i-RIP ifanele amanethiwekhi amancane, noma emaphethelweni amanethiwekhi amakhulu e-IP.
Njengeminye yemikhiqizo yethu ye-onu, kungenzeka ukulungisa le phrothokholi ye-RIP eguquguqukayo yomzila. Eminye imikhiqizo yethu ye-ONU yilena: i-olt onu, i-ac onu, i-Communications onu, i-optical fiber onu, i-catv onu, i-gpon onu, i-xpon onu, njll., ingenza ukwesekwa okuhlukile kwezindawo ezahlukene zenethiwekhi, wamukelekile ukuza ukuze ufunde kabanzi.
