Abstract

Raspodijeljene priručne memorije značajno smanjuju kašnjenje dohvata Internet stranica. Učinkovitost raspodijeljenih priručnih memorija određuju njihovi upravljački protokoli. Magistarski rad opisuje programsko ostvarenje direktorijskog upravljačkog protokola i uspoređuje direktorijski i Squid protokol na osnovi rezultata mjerenja. U svrhu programskog ostvarenja u sustavu Squid proučeni su komunikacijski standardi koji se koriste u suvremenim zastupničkim sustavima. Analiziran je protokol koji sustav Squid koristi za upravljanje raspodijeljenim zastupničkim sustavima. Na osnovi komunikacijskih standarda i postojećeg upravljačkog protokola definirane su nove komunikacijske poruke za upravljanje raspodijeljenom priručnom memorijom. Nakon programskog ostvarenja direktorijskog protokola, uspoređena su njegova svojstva sa svojstvima protokola Squid. U svrhu usporedbe protokola ostvaren je mjerni sustav za mjerenje kašnjenja direktorijskog i Squid protokola. Programski su ostvareni mjerni programi i definirani uvjeti izvođenja mjerenja. Prikupljeni rezultati grafički su prikazani i analizirani. Na osnovi analize uspoređena su svojstva proširivosti direktorijskog i Squid protokola.

Abstract (english)

Distributed cache systems significantly reduce the latency of Web page download. Efficiency of distributed cache systems is affected by the distributed cache management protocols. The master thesis describes an implementation of a directory-based cache management protocol. The thesis also compares the performance of Squid protocol and directory-based protocol. In order to implement directory-based protocol in Squid, communication standards used in modern proxy systems were studied. The cache management protocol used by Squid proxy was analyzed. Using the knowledge of communication standards and existing cache management protocols new cache management communication messages were defined. Once the directory-based protocol was implemented, its performance was compared to the performance of Squid protocol. In order to compare the performance of the protocols, a measurement system was developed. The measurement system was used to measure the latency of Squid protocol and directory-based protocol. Measurement programs were implemented and the measurement environment was defined. The measurement results are presented and analyzed. Based on the analysis, scalability of Squid and directory-based protocols is compared.
