Iprotocol yenethiwekhi ye-STP, ekwaziwa ngokuba yiProtocol yeSpanning Tree. Ukuvela kwale protokoli ikakhulu kusombulula ingxaki yonxulumano olungafunekiyo lwenza i-loops kuthungelwano. Njengesixhobo se-terminal sonxibelelwano lwenethiwekhi,OLTNgokungathintelekiyo idibana nemiba ye-loop yenethiwekhi yendawo kubuyo betopology yenethiwekhi. Ngelo xesha, ngenxa yobukho bomzimba wemiba ye-loop yenethiwekhi, kunzima ukuchonga ukuba yeyiphi inxalenye yezixhobo zenethiwekhi ezibangela ingxaki ye-loop.
Iprothokholi ye-STP kukwenza ulwakhiwo lomthi olunengqiqo ngokuvala ngengqiqo amanye amazibuko kumsebenzi womnatha onamaqhina abonakalayo ngokusebenzisa algorithm.
Njengoko kubonisiwe kulo mzobo ungentla, kukho izinto ezintathu zokutshintshela kwi-diagram ye-topology yenethiwekhi, kwaye kukho imiba ye-loop ebonakalayo kunye nokutshintsha okuthathu kuyilo lwenethiwekhi. Logama nje umsebenzi we-STP uvuliwe kwitshintsha, itshintshaikhetha ukuba yeyiphi izibuko lekhonkco elibonakalayo ukubhloka ngokusekelwe kwimithetho yeprothokholi.
Lonke unxibelelwano lweprotocol yesixhobo sothungelwano kuthungelwano lufumaneka ngonxibelelwano lomyalezo. I-STP isebenzisa i-BPDU (iYunithi yeDatha yeProtokholi yeBridge) ukwazisa ukuba yeyiphi indawo yonxibelelwano yonxibelelwano ekufuneka ivaliwe. Ukusetyenziswa komsebenzi we-STP akunakuvimba kuphela i-Link ye-1 yonxibelelwano yezibukotshintsha, kodwa sebenzisa i-Link 1 yonxibelelwano port njengendawo yokugcina. Nangona kunjalo, xa i-Link 3 ingakwazi ukunxibelelana, i-Link 1 port ivuliwe ukuqinisekisa unxibelelwano oluqhelekileyo lwenethiwekhi.
Kwimeko yenethiwekhi yanamhlanje, ngenxa yokuntsonkotha kokusingqongileyo kwenethiwekhi, i-STP ibe ngumsebenzi oyimfuneko kwizixhobo zeofisi ezinjengokutshintsha kunyeOLTs. Ukuze uhlangabezane neemfuno zemarike kwaye uhlangabezane neemfuno zesicelo sothungelwano lwabathengi, i-RSTP iye yavela njengenguqu ephuculweyo yokusebenza kwe-STP. Xa kuthelekiswa ne-STP, i-RSTP inokukhawuleza ifuduke ngokwemigaqo yokusebenza, kwaye isantya kunye nokusebenza kakuhle kwe-network convergence kungcono kune-STP. Ngexesha elifanayo, i-RSTP inokuhambelana ne-STP, oko kukuthi, iiswitshi ezimbini kwinethiwekhi, enye iqhuba i-STP kunye ne-RSTP. Umsebenzi usenokuphunyezwa, kodwa itshintshaesebenzayo RSTP izakutshintsha ngokuzenzekelayo isebenze i-STP.
Oku kungasentla sisishwankathelo esifutshane sothungelwano lweprotocol yeSTP yeteknoloji yesoftware, enokusebenza njengesalathiso kumntu wonke. Inkampani yethu inesoftware eyomeleleyo kunye neqela lobuchwephesha behardware, elinokubonelela ngeenkonzo zobugcisa kubathengi. Iimveliso zethu ezithengiswa kakhulu zigubungela iintlobo ezahlukeneyo zokutshintsha kunyeOLTiimveliso series. Ukuba ufuna, unokuqonda ngakumbi.
