Iphrothokholi yenethiwekhi i-STP, eyaziwa nangokuthi i-Spanning Tree Protocol.Ukuvela kwale phrothokholi ikakhulukazi kuxazulula inkinga yezixhumanisi ezingasasebenzi ezakha izihibe kunethiwekhi.Njengesisetshenziswa esibulalayo sokuxhumana kwenethiwekhi, i-OLT ihlangabezana nakanjani nezinkinga ze-loop yenethiwekhi kusakhiwo se-topology yenethiwekhi.Ngesikhathi esifanayo, ngenxa yokuba khona ngokomzimba kwezinkinga ze-loop yenethiwekhi, kunzima ukukhomba ukuthi iyiphi ingxenye yemishini yenethiwekhi ebangela inkinga ye-loop.
Iphrothokholi ye-STP iwukwenza ukwakheka kwesihlahla okunengqondo ngokuvimbela ngokunengqondo ezinye izimbobo kunethiwekhi enamaluphu abonakalayo ngokusebenzisa i-algorithm.
Njengoba kuboniswe esithombeni esingenhla, kukhona amaswishi amathathu kumdwebo we-topology yenethiwekhi, futhi kunezinkinga ze-loop ebonakalayo ngokushintsha okuthathu kusakhiwo senethiwekhi.Inqobo nje uma umsebenzi we-STP uvuliwe ekushintsheni, iswishi ikhetha ukuthi iyiphi imbobo yesixhumanisi esingokomzimba okufanele ivinjwe ngokusekelwe emithethweni yephrothokholi.
Konke ukuxhumana kwephrothokholi yedivayisi yenethiwekhi kunethiwekhi ngokuyisisekelo kufinyelelwa ngokusebenzisana komlayezo.I-STP isebenzisa i-BPDU (Iyunithi Yedatha Yephrothokholi Yebhuloho) ukuze yazise ukuthi iyiphi imbobo yokuxhumana yeswishi okufanele ivinjwe.Ukusetshenziswa komsebenzi we-STP akukwazi nje kuphela ukuvimba imbobo yokuxhumana ye-Link 1 yeswishi, kodwa futhi kusebenzise imbobo yokuxhumana ye-Link 1 njengendawo yokugcina ikhophi.Nokho, lapho i-Link 3 ingakwazi ukuxhumana, imbobo ye-Link 1 iyavulwa ukuze kuqinisekiswe ukuxhumana okuvamile kwenethiwekhi.
Esimweni senethiwekhi yanamuhla, ngenxa yobunkimbinkimbi bendawo yenethiwekhi, i-STP isiphenduke umsebenzi obalulekile kumishini yasehhovisi efana nokushintsha nama-OLT.Ukuze kuhlangatshezwane nezidingo zemakethe futhi kuhlangatshezwane nezidingo zenethiwekhi zamakhasimende, i-RSTP ivele njengenguqulo ethuthukisiwe yokusebenza kwe-STP.Uma kuqhathaniswa ne-STP, i-RSTP ingafuduka ngokushesha ngokwemibandela yokusebenza, futhi isivinini nokusebenza kahle kokuhlangana kwenethiwekhi kungcono kune-STP.Ngesikhathi esifanayo, i-RSTP ingahambisana ne-STP, okungukuthi, amaswishi amabili kunethiwekhi, eyodwa egijima i-STP kanti enye isebenzisa i-RSTP.Umsebenzi usengafezwa, kodwa iswishi egijima i-RSTP izoshintsha ngokuzenzakalelayo isebenze i-STP.
Okungenhla ukubuka okufushane kobuchwepheshe besofthiwe yenethiwekhi ye-STP, engasebenza njengereferensi yawo wonke umuntu.Inkampani yethu ineqembu eliqinile le-software ne-hardware lobuchwepheshe, elingahlinzeka ngezinsizakalo zobuchwepheshe kumakhasimende.Imikhiqizo yethu edayiswa kakhulu ihlanganisa izinhlobo ezahlukene zokushintshwa kanye nemikhiqizo yochungechunge lwe-OLT.Uma udinga, ungaqhubeka uqonde.
