Network protocol STP, yomwe imadziwikanso kuti Spanning Tree Protocol.Kuwonekera kwa protocol iyi makamaka kumathetsa vuto la maulalo osafunikira omwe amapanga malupu pamaneti.Monga chida chothandizira kulumikizana ndi netiweki, OLT imakumana ndi zovuta zama netiweki pamawonekedwe a network topology.Panthawi imodzimodziyo, chifukwa cha kupezeka kwakuthupi kwa nkhani za loop network, zimakhala zovuta kudziwa kuti ndi gawo liti la zida zapaintaneti zomwe zikuyambitsa vuto la loop.
Protocol ya STP ndiyopanga mtengo womveka bwino potsekereza madoko ena pamaneti okhala ndi malupu akuthupi kudzera mu algorithm.
Monga momwe tawonetsera pa chithunzi pamwambapa, pali masiwichi atatu pazithunzi za netiweki topology, ndipo pali zovuta za kuzungulira kwakuthupi ndi masiwichi atatu pamawonekedwe a netiweki.Malingana ngati ntchito ya STP yayatsidwa pakusintha, chosinthiracho chimasankha doko lolumikizana ndi thupi lomwe lingatseke potengera malamulo a protocol.
Kuyankhulana konse kwa protocol ya netiweki pamanetiweki kumatheka kudzera mukulankhulana kwa mauthenga.STP imagwiritsa ntchito BPDU (Bridge Protocol Data Unit) kuti idziwitse malo olumikizirana ndi switch omwe akuyenera kutsekedwa.Kugwiritsa ntchito ntchito ya STP sikungalepheretse doko la kulumikizana kwa Link 1, komanso kugwiritsa ntchito doko lolumikizana la Link 1 ngati doko losunga zobwezeretsera.Komabe, Link 3 ikalephera kulankhulana, doko la Link 1 limatsegulidwa kuti zitsimikizire kulumikizana kwanthawi zonse.
M'malo amasiku ano amtaneti, chifukwa chazovuta zapaintaneti, STP yakhala ntchito yofunika kwambiri pazida zamaofesi monga ma switch ndi ma OLT.Pofuna kukwaniritsa zosowa za msika ndikukwaniritsa zofunikira za makasitomala, RSTP yatulukira ngati njira yowonjezereka ya machitidwe a STP.Poyerekeza ndi STP, RSTP imatha kusamuka mwachangu malinga ndi magwiridwe antchito, ndipo liwiro ndi magwiridwe antchito a network convergence ndizabwino kuposa STP.Panthawi imodzimodziyo, RSTP ikhoza kukhala yogwirizana ndi STP, ndiko kuti, zosintha ziwiri pamaneti, imodzi ikuyenda STP ndi ina ikuyendetsa RSTP.Ntchitoyi itha kukwaniritsidwabe, koma chosinthira chomwe chikuyendetsa RSTP chidzasintha kukhala STP.
Zomwe zili pamwambazi ndizofotokozera mwachidule zaukadaulo wa pulogalamu yapaintaneti ya STP, yomwe imatha kukhala yofotokozera aliyense.Kampani yathu ili ndi mapulogalamu amphamvu komanso gulu laukadaulo la hardware, lomwe limatha kupereka chithandizo chaukadaulo kwa makasitomala.Zogulitsa zathu zomwe zimagulitsidwa kwambiri zimaphimba mitundu yosiyanasiyana ya masiwichi ndi zinthu za OLT.Ngati mukufuna, mutha kumvetsetsa.
