Maulana, Muhamad Rizka (2018) Analisis Kinerja On-Path Caching Dan Off-Path Caching Pada Information-Centric Networking. Sarjana thesis, Universitas Brawijaya.
Abstract
Peningkatan lalu lintas data di Internet yang sangat tinggi tidak didukung oleh arsitektur Internet saat ini yang masih bersifat host-centric. Paradigma Information-centric Networking (ICN) berusaha untuk mengatasi masalah tersebut dengan model komunikasi yang bersifat content-centric atau information-centric. Beberapa konsep arsitektur berbasis ICN telah diusulkan seperti CCN, DONA, dan NetInf. Arsitektur baru tersebut umumnya memiliki tiga kesamaan konsep kerja, yaitu operasi Publish-Subscribe, In-network Caching, dan Content-oriented Security. In-network caching memainkan peran penting dalam meningkatkan kinerja jaringan dengan cara menyimpan konten di cache yang tersebar di jaringan. Terdapat 2 jenis mekanisme in-network caching, yaitu onpath caching dan off-path caching. Sebelum arsitektur ICN diterapkan, perlu adanya studi analisis kinerja in-network caching agar nantinya dapat dijadikan sebagai acuan. Penelitian ini bertujuan untuk menganalisis dan membandingkan kinerja on-path caching dan off-path caching pada topologi Biznet menggunakan simulator Icarus. Metrik kinerja yang digunakan adalah cache hit ratio (CHR), latensi, dan link load. Hasil pengujian menunjukkan bahwa dalam aspek cache hit ratio, mekanisme off-path caching memiliki CHR 12,45% lebih tinggi dibandingkan mekanisme onpath caching. Sementara dalam aspek link load, mekanisme on-path caching memiliki link load 63,14% lebih rendah dibandingkan dengan mekanisme offpath caching. Dan dalam aspek latensi, mekanisme on-path caching memiliki latensi 42,07% lebih rendah dibandingkan dengan mekanisme off-path caching. Selain itu, ditemukan pula bahwa semakin besar kapasitas cache dan nilai α berarti semakin tinggi cache hit ratio, semakin rendah link load, serta semakin rendah latensi
English Abstract
The massively increasing Internet traffic is not supported by the current Internet architecture which is still based on host-centric communication. Information-centric networking (ICN) paradigm has been proposed to resolve that problem with content-centric communication. Some ICN architectures have been proposed, such as CCN, DONA, and NetInf. Those proposed architectures generally have three main concepts, which are publish-subscribe operation, innetwork caching, and content-oriented security. In-network caching plays a very important role in ICN paradigm. It can improve network performance by saving content in caches that are spread in the network. There are two types of innetwork caching, which are on-path caching and off-path caching. Before the ICN architecture is deployed to replace current architecture, it is necessary to conduct a performance analysis of in-network caching so that the result can be used as a reference for the deployment. This research aims to analyze and to compare onpath and off-path caching strategies on Biznet topology using Icarus simulator. Cache hit ratio, latency, and link load are used as performance metrics. The result of this research shows that off-path caching has 12.45% higher cache hit ratio than on-path caching, and on-path caching has 63.14% lower link load and 42,07% lower latency than off-path caching. In addition to that, it is worth noted that bigger cache capacity and α value results in higher cache hit ratio, lower link load, and lower latency.
