STP ndi chiyani?

STP (Spanning Tree Protocol) ndi njira yolumikizirana yomwe imagwira ntchito pagawo lachiwiri (data link layer) mu mtundu wa OSI network. Ntchito yake yayikulu ndikuletsa malupu omwe amayamba chifukwa cha maulalo ochulukirapo pama switch. Amagwiritsidwa ntchito kuwonetsetsa kuti palibe loop mu Ethernet. The logic topology .Chifukwa chake, mphepo yamkuntho yowulutsa imapewedwa, ndipo kuchuluka kwazinthu zosinthira kumakhala.

Spanning Tree Protocol idakhazikitsidwa ndi algorithm yopangidwa ndi Radia Perlman ku DEC ndikuphatikizidwa mu IEEE 802.1d, mu 2001, bungwe la IEEE lidakhazikitsa Rapid Spanning Tree Protocol (RSTP), yomwe imakhala yothandiza kwambiri kuposa STP pomwe ma network akusintha. Network yolumikizana mwachangu idayambitsanso gawo la doko kuti lipititse patsogolo njira yolumikizira, yomwe idaphatikizidwa mu IEEE 802.1w.

Kodi OSI ndi chiyani?

(OSI) Open System Interconnection Reference Model, yotchedwa OSI model (OSI model), chitsanzo chamalingaliro, choperekedwa ndi International Organisation for Standardization, chimango chopangira makompyuta osiyanasiyana padziko lonse lapansi Interconnect. Kutanthauziridwa mu ISO/IEC 7498-1.
