GRID servisų kokybės parametrai labai aktualus klausimas šiais laikais. Šiame darbe pristatoma sukurta metodika GRID Servisų kokybės efektyvumo tyrimui. Taip pat pristatoma metodika kaip atlikti preliminarūs GRID tinklų parametrų skaičiavimai. Bei atliktas eksperimentas ir eksperimento rezultatai. / Nowadays GRID computing issues become urgent. GRID quality of service (QoS) importance grows together with the development of GRID technology. The importance of QoS of the grid lies in at least three aspects: the concept of grid service, the multiplicity of users’ demands, and the heterogeneity of grid resources (Pu Juhua, Xiong Zhang and Wu Zhenxing. The Research On QoS For Grid Computing.). Besides discussing GRID QoS parameters, there are also suggestions about the methods to obtain them. The scope of this document is to research the GRID QoS aspects and the description of developed methodology for estimating QoS efficiency evaluating network and clusters parameters. The results of efficiency experiments done using the developed methodology are presented there.

Šis darbas aprašo pagrindinius Grid paslaugų kūrimo metodus, kurie bando pasiūlyti operacinius suderinamumus, stabilumą ir produktyvumą, nepaisant to, kad pasaulinio tinklo paslaugos yra jauna technologija su keliais standartais. Tikimės, kad Grid paslaugos sukurtos iš pasaulinio tinklo paslaugų parodys vykdymo problemas, bent jau pradžioje, ir kad eksperimentavimas ir alternatyvų kūrimas, pareikalaus efektyvesnių pasaulinio tinklo paslaugų realizacijų. Pasiūlytas modelis sukurtas Grid architektūros pagrindu, taip išvengiant rizikos perkurti visą infrastuktūrą. / This work has described an approach to building Grid Services that attempts to promote interoperability, stability and productivity, despite the fact that Web Services are a young technology with few standards. We anticipate that Grid services built from Web Services will show performance problems, at least initially, and that experimentation and development of alternate, more efficient implementations of some of these Web Services will be necessary. Proposed model is based on existing Grid architecture, without the risk of rebuilding the whole infrastructure.
