Resource Allocation Guidelines : Configuring a large telecommunication application / Riktlinjer för resursallokeringEriksson, Daniel January 2001 (has links)
Changing the architecture of the Ericsson Billing Gateway application has shown to solve the problem with dynamic memory management that decreased the performance. The new architecture that is focused on processes instead of threads showed increased performance. It also allowed for the possibility to adjust the process / thread configuration towards the network topology and hardware. Measurements of different configurations showed the importance of an accurate configuration and also that certain guidelines could be established based on the results. / Genom att ändra architecturen på Billing Gateway löste man på Ericsson problemet med "Dynamisk minneshantering". Den nya architecturen som fokuserar på processer istället för trådar visade ökad prestanda. Den nya architecturen tillät också vissa konfigurationsmöjligheter gentemot nätverkstopologi och hårdvara. Mätningar på olika konfigurationer visade vikten av rätt konfiguration och också att vissa riktlinjer kunde utrönas från resultaten. / Phone#: +46 457 66582

Inteligentní distribuce souborů v CDN / Intelligent File Distribution in CDNKaleta, Marek January 2014 (has links)
This work deals with algorithms for distributing and mapping content on nodes in CDN system. Compares local and global algorithms for loading files on origin and edge servers. A high level CDN simulator is made. A matrix based approach for mapping content on CDN servers is proposed along with tranformation for solution of mapping optimalisation through genetic algorithms.

Implementace CDN a clusteringu v prostředí GNU/Linux s testy výkonnosti. / CDN and clustering in GNU/Linux with performance testingMikulka, Pavel January 2008 (has links)
Fault tolerance is essential in a production-grade service delivery network. One of the solution is build a clustered environment to keep system failure to a minimum. This thesis examines the use of high availability and load balancing services using open source tools in GNU/Linux. The thesis discusses some general technologies of high availability computing as virtualization, synchronization and mirroring. To build relatively cheap high availability clusters is suitable DRDB tool. DRDB is tool for build synchronized Linux block devices. This paper also examines Linux-HA project, Redhat Cluster Suite, LVS, etc. Content Delivery Networks (CDN) replicate content over several mirrored web servers strategically placed at various locations in order to deal with the flash crowds. A CDN has some combination a request-routing and replication mechanism. Thus CDNs offer fast and reliable applications and services by distributing content to cache servers located close to end-users. This work examines open-source CDNs Globule and CoralCDN and test performance of this CDNs in global deployment.

Dostupná řešení pro clustrování serverů / Available Solutions for Server ClusteringBílek, Václav January 2008 (has links)
The goal of this master thesis is to analyze Open Source resources for loadbalancing and high availability, with aim on areas of its typical usage. These areas are particularly solutions of network infrastructure (routers, loadbalancers), generally network and internet services and parallel filesystems. Next part of this thesis is analysis of design, implementation and plans of subsequent advancement of an fast growing Internet project. The effect of this growth is necessity of solving scalability on all levels. The last part is performance analysis of individual loadbalancing methods in the Linux Virtual Server project.
