Analisis Performansi VLAN Pada Jaringan Software Defined Network (SDN)
Main Article Content
Abstract
Software defined network (SDN) adalah sebuah paradigma baru dalam dunia jaringan yang mampu memusatkan fungsi beberapa control plane pada layer 2 maupun di layer 3 secara terprogram, hal tersebut menyebabkan jaringan akan bersifat lebih fleksibel dan terskala. Dengan jumlah pertumbuhan pengguna internet yang semakin tinggi maka hal tersebut akan berbanding lurus terhadap kompleksitas dari jaringan internet itu sendiri. Sehingga paradigma SDN ini menjadi salah satu solusi yang muncul. Penerapan Virtual Local Area Network (VLAN) pada jaringan tradisional telah menjadi hal yang penting dan banyak diterapkan. Fungsi VLAN adalah untuk membatasi broadcast trafik dari suatu host, sehingga hanya dapat mengirim data kepada VLAN ID yang sama. Penelitian ini menganalisis performansi VLAN di jaringan SDN. Terjadi penurunan angka jumlah paket yang dapat terkirim (data transfer) dan nilai throughput pada sebuah VLAN ID karena terdapat pengaruh dari VLAN ID yang berbeda. Pada pengujian membandingkan VLAN dengan non VLAN over Netwok Functions Virtualization (NFV) didapatkan bahwa nilai data transfer dan throughput yang diperoleh pada VLAN lebih besar. Hasil analisis dari seluruh pengujian penambahan traffic terlihat bahwa kinerja VLAN pada SDN akan membebani kinerja jaringan pada VLAN yang berbeda
