The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.
Fungsi dasar dari STP adalah untuk mencegah pengulangan penghubung dan radiasi siaran yang dihasilkan dari mereka.
STP is based on an algorithm that was invented by Radia Perlman while she was working for Digital Equipment Corporation.
STP ini berdasarkan algoritme yang ditemukan oleh Radia Perlman ketika bekerja untuk Digital Equipment Corporation.
The first Spanning Tree Protocol was invented in 1985 at the Digital Equipment Corporation by Radia Perlman.
Spanning Tree Protocol pertama ditemukan pada tahun 1985 di Digital Equipment Corporation oleh Radia Perlman.
In 1990, the IEEE published the first standard for the protocol as 802.1D, based on the algorithm designed by Perlman.
Pada tahun 1990, IEEE menerbitkan standar pertama untuk protokol sebagai 802.1D, berdasarkan algoritma yang dirancang oleh Perlman.
Subsequent versions were published in 1998 and 2004, incorporating various extensions.
Berikut versi diterbitkan pada tahun 1998 dan 2004, yang menggabungkan berbagai ekstensi.
The original Perlman-inspired Spanning Tree Protocol, called DEC STP, is not a standard and differs from the IEEE version in message format as well as timer settings.
Selain itu, awalnya Perlman terinspirasi Spanning Tree Protocol, yang disebut DEC STP, bukan standar dan berbeda dari versi IEEE pada format pesan serta pengaturan waktu.
The IEEE encourages vendors to provide a Protocol Implementation Conformance Statement, declaring which capabilities and options have been implemented, to help users determine whether different implementations will interoperate correctly.
IEEE mendorong vendor untuk menyediakan "Protocol Implementation Conformance Statement", menyatakan kemampuan dan pilihan yang telah dilaksanakan, untuk membantu pengguna menentukan apakah implementasi yang berbeda akan interwork dengan benar.
In 2001, the IEEE introduced Rapid Spanning Tree Protocol (RSTP) as IEEE 802.1w.
IEEE 802.1w - 2004 Rapid Spanning Tree Protocol (RSTP) IEEE 802.1s - 2005 Multiple Spanning Tree Protocol (MSTP)
RSTP was then incorporated into IEEE 802.1D-2004 making the original STP standard obsolete.
