Analisis Simulasi Penerapan Algoritma OSPF Menggunakan RouteFlow pada Jaringan Software Defined Network (SDN)

Pada jaringan konvensional, konfigurasi protocol routing sangat tidak fleksibel, tidak efisien dan konfigurasi dilakukan pada tiap perangkat. Hal ini tentu saja tidak dapat memenuhi tuntutan operasional saat ini yang rata-rata memiliki jaringan yang besar dan perangkat jaringan yang memiliki spesifikasi berbeda. Software Defined Network (SDN) muncul sebagai harapan untuk permasalahan kompleksitas jaringan konvensional. Paradigma baru SDN melakukan pemisahan antara control plane dan forwarding plane. RouteFlow merupakan salah satu komponen berbasis software yang dapat mengaplikasikan protocol routing konvensional pada jaringan SDN. Open Shortest Path First (OSPF) merupakan sebuah protokol routing konvensional yang memiliki kemampuan untuk mendeteksi perubahan topologi jaringan dengan cepat dalam sebuah jaringan yang besar. Protokol routing OSPF diterapkan pada teknologi SDN menggunakan RouteFlow dengan tujuan untuk mempermudah dalam mengontrol jaringan dengan sistem terpusat. Convergence time dan parameter Quality of Service (Throughput, Delay, Jitter dan Packet Loss) diukur dengan skenario pemutusan link, penambahan jumlah switch dan background traffic.  Hasil pengukuran convergence time menunjukan bahwa penambahan jumlah switch mempengaruhi pertambahan waktu konvergensi, sedangkan untuk parameter Quality of Service (QoS) pada peningkatan topologi switch didapatkan hasil yang masih sesuai dengan standar ITU-T G.1010 namun apabila ditambahkan background traffic yang memenuhi 50% bandwidth jaringan maka QoS memburuk.Pada jaringan konvensional, konfigurasi protocol routing sangat tidak fleksibel, tidak efisien dan konfigurasi dilakukan pada tiap perangkat.

Implementation model architecture software defined network using raspberry Pi: a review paper

Software defined network (SDN) made with basic concepts that are different from traditional networks in controlling the network, the separation between the control layer and forwarding layer on different devices allows the administrator to adjust the control plan for all devices centralized in one action, while in traditional network, the control and forwarding layers are located in the infrastructure making network administrator must manage devices one by one. Research using single board computers on network technology provides an opportunity to implement SDN architecture. Raspberry Pi has sufficient ability. QoS results meet the ITU-T G.1010 reference which indicates that Raspberry Pi can be used on designed networks

Implementation of Role-Based Access Control on OAuth 2.0 as Authentication and Authorization

As today’s technology transition from monolithic towards microservices architecture, the authentication and authorization system also becomes a new concern because of the difference between monolithic and microservices pattern. Monolithic mostly uses role-based access control while microservices uses scope with OAuth 2.0. With this in mind, there is a need for a model that can integrate OAuth 2.0 with role-based access control. With rolebased access control implemented on OAuth 2.0, we expect a simpler authorization process and a more secure authentication and authorization system for microservices backend architecture. This paper proposes a model to implement role-based access control on OAuth 2.0 using Laravel framework, we also test the performance of the system following by response time, data transferred and throughput. From the performance test, this approach has a good performance and can handle certain requests with simulated users even with limited resources
