Urusobe protocole STP, izwi kandi nka Spanning Tree Protocol. Kugaragara kwi protocole bikemura cyane cyane ikibazo cyibihuza bitagira ingano bikora imirongo. Nka gikoresho cya terefone yo gutumanaho,OLTbyanze bikunze uhura nibibazo byurusobe rwumubiri murwego rwimiterere ya topologiya. Muri icyo gihe, bitewe nuburyo bugaragara bwibibazo byurusobe, biragoye kumenya igice cyibikoresho byurusobe bitera ikibazo cyumuzingi.
Porotokole ya STP nugukora ibiti byumvikana muburyo bwo guhagarika ibyambu bimwe murusobe rufite imirongo ifatika binyuze muri algorithm.
Nkuko bigaragara kuri iyi shusho yavuzwe haruguru, hariho uburyo butatu bwo gushushanya mubishushanyo mbonera bya topologiya, kandi hariho ibibazo byumubiri bifatika hamwe na bitatu byahinduwe muburyo bw'urusobe. Igihe cyose imikorere ya STP ishoboye kurihindura, ihindurahitamo icyerekezo gifatika cyo guhagarika gishingiye kumategeko ya protocole.
Ibikoresho byose byurusobekerane rwitumanaho murusobe bigerwaho muburyo bwubutumwa. STP ikoresha BPDU (Bridge Protocol Data Unit) kugirango imenyeshe icyambu cyitumanaho gikeneye guhagarikwa. Imikoreshereze yimikorere ya STP ntishobora guhagarika gusa icyambu cya 1 cyitumanaho cyahindura, ariko kandi ukoreshe icyambu cya 1 cyitumanaho nkicyambu cyinyuma. Ariko, mugihe Ihuza 3 ridashoboye kuvugana, icyambu cya 1 kirakora kugirango habeho itumanaho risanzwe.
Muri iki gihe urusobe rwibidukikije, bitewe nuburyo bugoye bwibidukikije, STP yabaye umurimo wingenzi kubikoresho byo mu biro nka switch naOLTs. Kugirango uhuze ibikenewe ku isoko kandi wuzuze ibisabwa byo gusaba imiyoboro y'abakiriya, RSTP yagaragaye nka verisiyo yazamuye imikorere ya STP. Ugereranije na STP, RSTP irashobora kwimuka vuba mubijyanye nimikorere, kandi umuvuduko nuburyo bwiza bwo guhuza imiyoboro nibyiza kuruta STP. Mugihe kimwe, RSTP irashobora guhuzwa na STP, ni ukuvuga, ibintu bibiri byahinduwe murusobe, umwe ukoresha STP undi akoresha RSTP. Imikorere irashobora kugerwaho, ariko ihinduragukora RSTP izahita ihinduka kuri STP ikora.
Ibyavuzwe haruguru ni incamake muri make ya protocole y'urusobe rw'ikoranabuhanga rya porogaramu ya STP, ishobora kuba nk'ibisobanuro kuri buri wese. Isosiyete yacu ifite software ikomeye hamwe nitsinda rya tekiniki ryibikoresho, rishobora gutanga serivisi zumwuga kubakiriya. Ibicuruzwa byacu byagurishijwe cyane bikubiyemo ubwoko butandukanye bwo guhinduranya kandiOLTibicuruzwa bikurikirana. Niba ukeneye, urashobora kurushaho gusobanukirwa.
