Abstract
Vi præsenterer en ny arkitektur for en Grid Information Service, der er designet til at være skalerbar, fejltolerant og fleksibel. To centrale elementer er: 1) noder bruger Optimized Link State Routing Protocol (OLSR), en routing-protokol der lader dem automatisk finde og vedligeholde forbindelser og dermed selvorganisere netværksstrukturen; og 2) ressourceinformation cirkulerer og opdateres efter, hvor længe den er gyldig, så kun aktuelle data spredes. Arkitekturen er implementeret, og systemet fungerer som forventet. Med OLSR kan netværket automatisk opbygges og vedligeholdes, og strukturen viser fejltolerance (systemet fortsætter med at virke, selv hvis nogle dele fejler) og fleksibilitet (systemet kan tilpasse sig ændringer). Gennemførte ydeevneforsøg indikerer, at systemet skalerer godt, når netværket vokser.
We present a new architecture for a Grid Information Service designed to be scalable, fault-tolerant, and flexible. Two key features are: 1) nodes use the Optimized Link State Routing Protocol (OLSR), a routing protocol that lets them automatically find and maintain paths and thus self-organize the network structure; and 2) resource information is disseminated and refreshed based on how long it remains valid, so only current data circulates. The architecture was implemented, and the system works as intended. With OLSR, the network can automatically build and maintain itself, and the structure shows fault tolerance (it keeps working even if some parts fail) and flexibility (it adapts to changes). Performance experiments indicate that the system scales well as the network grows.
