Spanning Tree protocol atau yang sering disingkat dengan STP adalah metode pada jaringan yang menjamin tidak adanya loop dalam jaringan. Dengan model jaringan OSI untuk jaringan komputer, STP ada di layer 2 OSI. Spanning tree protocol memperbolehkan desain jaringan memiliki redundant link untuk membuat jalur backup otomatis. Dengan menggunakan metode spanning tree protocol maka apabila perangkat switch cisco catalyst tersebut down maka akan berimbas pada jaringan tersebut karena sudah ada backup link. Apabila main link down atau terputus, maka port yang tadi terblok akan terbuka oleh switch, sehingga data dari komputer pengirim akan melewati redundant.Kata Kunci: Jaringan, Komputer, Spanning

Is it strange that the spanning tree protocol (STP) has been the only thing used to defend the Layer-2 backbone against looping? Do we trust it? For several decades, the campus backbone has often been an unsuspected problem, one of which is STP failure. Meanwhile, the MAC address flapping is probably a feasible issue for modern network fabrics. According to the serious Layer-2 issues, particularly the legacy switches extended STP design, this work uses the notion of a software-defined network fashion to evaluate the traditional and modern networks. Through the MAC address lookup of all bridge devices, this work proposes the Layer-2 evaluation system (LES), which uses a novel approach known as support supervised learning to create the data preparation for machine learning. Additionally, the LES enabled network administrators to determine their backbones. This study is intended to evaluate the potential slowdown network caused by MAC address problems. Furthermore, this work investigates the proposed method in a real network, and it also covers the evaluation and performance of our proposed method.

SDN is approaching its own structure of acceptance. Therefore, the increasing deployment of SDNs is being discussed as a possible approach, appearing in the development of the hybrid SDN networks. An foremost work in the hybrid SDN networks is bandwidth allocation, taking into account the integration of both SDN-enabled and conventional switches. The network loop in layer 2 switches is skipped in Spanning Tree Protocol (STP) by ceaselessly watching the network to trace all links and block the unwanted ones. Bridge loops will occur anytime there’s a redundant Layer2 way between ends. By default, switches forward broadcast/multicast out all ports, other than the port from that the broadcast/multicast was delivered. Once a switch loop is brought in the network, broadcast messages are going to be broadcasted more often leading to broadcast storms. The Spanning-tree algorithm enforces a distributed divergent of the Bellman-Ford iterative algorithm that always looks for the optimal solution and selects an optimal influential switch anytime. In this paper we use controller’s global network view for resolving loop problem in layer 2 network. SDN controller acts on broadcast packets received from switch-ports and host-ports differently that is if the broadcast packets received from host ports, the SDN controller broadcasts these packets to all ports and if broadcast packets is received from switch ports, only some switches broadcasts these packets on all ports instead of all switches.

Loop Network

Spanning Tree Protocol (STP) adalah layanan yang memungkinkan LAN switch dan LAN bridge terinterkoneksi secara berlebih dengan cara menyediakan mekanisme untuk mencegah loop yang tidak diinginkan dalam jaringan yang terjadi pada bridge. Tanpa adanya STP, pada frame Ethernet akan terjadi loop untuk periode tak terbatas di dalam waktu jaringan dengan link berlebihan secara fisik. Untuk mencegah loop pada frame Ethernet, STP memblok beberapa port dari frame Ethernet  sehingga hanya satu jalur yang aktif ada di antara setiap pasang segmen LAN (collision domain). Hasil STP adalah loop frame Ethernet tidak terbatas yang membuat LAN dapat digunakan. Satu hal yang perlu diperhatikan adalah bahwa Redundant link tidak untuk keseimbangan beban, karena hanya satu link aktif. Cara kerja Spanning Tree Protocol adalah menggunakan algoritma spanning tree yang secara otomatis menemukan topologi jaringan dan membentuk suatu jaringan tunggal yang optimal melalui suatu bridge jaringan dengan menugasi fungsi-fungsi yang ada pada setiap bridge. STP Menghentikan terjadinya loo-loop network pada network layer 2 (bridge atau switch). STP secara terus menerus memonitor network untuk menemukan semua link, memastikan bahwa tidak ada loop yang terjadi dengan cara mematikan semua link yang redundant. STP menggunakan algoritma yang disebut Spanning Tree Algorithm (STA) untuk menciptakan sebuah topologi database, kemudian mencari dan menghancurkan link-link redundant. Dengan menjalankan STP, frame-frame hanya akan diteruskan pada link-link utama yang dipilih oleh STP.

A proper network optimization is needed to deal with problems on the network and to minimize latency in the data flow in a dense network. The data stream is directed into the right channels so that the optimal network speed and latency can be minimized. Spanning tree is one of the algorithms that can be used. The purpose of the Spanning tree is to prevent and reduce the loops in the network by negotiating free path and as well as to increase network uptime through redundancy (back-up). To comprehend spanning tree, the first important thing to know is how bridges and switches perform their functions. The more switches used, the use of the spanning tree becomes more important. With the spanning tree protocol, a broadcast storm can be prevented that can achieved network optimization.
