Analisis Performansi Perutingan Link State Menggunakan Algoritma Djikstra Pada Platform Software Defined Network (SDN)
Main Article Content
Abstract
Software Defined Network (SDN) merupakan paradigma baru dalam sistem jaringan. Konsep dasar yang diusung oleh SDN adalah pemisahan antara layer control dan forward dalam perangkat yang berbeda. Konsep inilah yang menjadi perbedaan anatar SDN dan jaringan konvensional. Selain itu SDN memberikan konsep network topology virtualisation dan memungkinkan administrator untuk melakukan customize pada control plane. Dengan diterapkannya protokol OpenFlow pada SDN maka terdapat peluang untuk menerapkan perutingan flow based pada jaringan SDN dalam pendistribusian data dari source sampai ke destination. Link state IS-IS merupakan protokol routing yang menggunakan algoritma djikstra untuk menentukan jalur terbaik dalam pendistribusian paket. Dalam penelitian ini dilakukan analisis terhadap implementasi Link State IS-IS pada paltform SDN dengan menggunakan arsitektur RouteFlow. Parameter yang digunakan adalah throughput, delay, jitter dan packet loss serta performansi perangkat controller. Hasil pengujian pada kondisi overload yaitu dengan background traffic 125 Mb nilai packet loss mencapai 1,23%, nilai throughput 47,6 Mbp/s dan jitter 2.012 ms. Nilai delay terbesar adalah pada topology 11 switch 11 host yaitu berkisar diangka 553 ms. Sedangkan performansi perangkat controller dengan konsumsi memory pada saat menjalankan mengontrol jaringan berkisar diantara 25,638% sampai 39,04%
