Information-Centric Networking Cache Placement Method Based on Cache Node Status and Location

Information-Centric Networking with caching is a very promising future network architecture. The research on its cache deployment strategy is divided into three categories, namely, noncooperative cache, explicit collaboration cache, and implicit collaboration cache. Noncooperative caching can cause problems such as high content repetition rate in the web cache space. Explicit collaboration caching generally reflects the best caching effect but requires a lot of communication to satisfy the exchange of cache node information and depends on the controller to perform the calculation. On this basis, implicit cooperative caching can reduce the information exchange and calculation between cache nodes while maintaining a good caching effect. Therefore, this paper proposes an on-path implicit cooperative cache deployment method based on the dynamic LRU-K cache replacement strategy. This method evaluates the cache nodes based on their network location and state and selects the node with the best state value on the transmission path for caching. Each request will only select one or two nodes for caching on the request path to reduce the redundancy of the data. Simulation experiments show that the cache deployment method based on the state and location of the cache node can improve the hit rate and reduce the average request length.

MEMBANGUN PROXY SERVER WEB CACHE DENGAN ANALISIS PERBANDINGAN CACHE REPLACEMENT PADA SQUID PROXY

Pada sebuah jaringan komputer terdapat Proxy server yang memiliki fungsi salah satunya caching. Mekanisme caching pada proxy server adalah menyimpan objek-objek yang merupakan hasil permintaan komputer client dari internet dan memberikan layanan jika client akan mengaksesnya kembali tanpa meminta sepenuhnya ke internet. Mengingat bahwa cache memory merupakan penyimpanan yang tetap maka dapat memungkinkan terjadinya cache memory penuh, untuk mengoptimalisasi kinerja cache memory terdapat metode cache replacement pada proxy server. Cache replacement pada proxy server merupakan metode penghapusan objek pada cache memory untuk digantikan dengan objek baru yang bertujuan agar cache memory tidak penuh. Maka dari itu penulis akan membangun sebuah proxy server web cache serta menganalisis algoritme Least recently used dan Greedy dual size frequently sebagai aturan cache replacement pada squid proxy dengan menggunakan metode pengembangan Netwok Development Live Cycle (NDLC) Cisco PPDIOO. Kata kunci: Proxy server, Caching, Cache Replacement, LRU, GDSF, Cisco PPDIOO.

A Review of Probabilistic Techniques Used for Web browsers’ Caching

Cache memory plays a central role in improving the performance of web servers, especially for big data transmission, which response time is constrained. It is necessary to use an effective method, such as web cache. Browsers' cache has a significant role according to less bandwidth use, response time and traffic load as well as beneficial if the internet connection is slow. Due to the space limitations, modern browsers companies attempt to use a method to store a great number of web objects and to advance the effectiveness of web browsers. Many scientists have been working to discover and recommend various techniques for this purpose. This study consequently reviews the recent likelihood probabilistic methods, to figure out how browsers store web objects in their caches, and which methods are used to load more speedily and to store a great number of web objects. The comparison between numerous browsers performed to pick and recommend the utmost one for usage. The result has shown that each browser using RI (Ratio Improvement) has powerful performance; to be discussed later. It has proposed using Google Chrome browser because web objects are placed in its cache through the RI technique that correlated with browsers' effectiveness.

PENERAPAN TEKNOLOGI CACHE SERVER BERBASIS IoT DENGAN RASPBERRY Pi3 MENGGUNAKAN METODE FORWARD CHAINNING

With the rapid technological development, the growing number of Internet clients over time, the internet access response is slow and it takes filtering of a few websites that can harm users. For that required cache proxy server to speed up internet access time and website filtering. The use of proxy servers usually still use the standard configuration on the proxy server. This configuration can be set or modified (tuning) in such a way as to create a proxy server that is reliable and have better performance. The play on the proxy server is done by changing some parameters that are inside the proxy server application and adapted to the needs of usage on the internet network. The application used to create this proxy server is squid that runs on raspberry pi3 with a rasbian operating system. Squid applications are mostly used in local and internet networks for storing web cache, blocking multiple websites, managing bandwidth up to access restrictions.
