Abstract

Povećanjem broja korisnika, poslužiteljski mrežni čvorovi na kojima se izvršavaju korisničke usluge postaju preopterećeni. Preopterećenost se može smanjiti dodavanjem novih primjeraka korisničkih usluga koji preuzimaju dio opterećenja. Mehanizmima za uravnoteženje opterećenja moguće je korisničke zahtjeve ravnomjerno rasporediti na više primjeraka korisničkih usluga. U okviru magistarskog rada analizirane su postojeće tehnologije i mehanizmi uravnoteženja opterećenja. Analiziran je MidArc posrednički sustav i opisana je arhitektura sustava za uravnoteženje opterećenja korisničkih usluga. Sustav za uravnoteženje opterećenja je ostvaren i ugrađen u MidArc posrednički sustav. Objašnjeni su i ostvareni mehanizmi upravljanja sustavom za uravnoteženje opterećenja. Objašnjena je arhitektura sustava za dodavanje novih primjeraka korisničkih usluga u posrednički sustav. Sustav za dodavanje primjeraka korisničkih usluga programski je ostvaren i ugrađen u MidArc posrednički sustav. Iskustva stečena u razvoju sustava za uravnoteženje opterećenja ukazuju na korisnost primjene takvih sustava u ostvarenju posredničkih sustava.

Abstract (english)

The growing number of users increases the load on the distributed computing systems that execute the services. One way to prevent a server from overloading is to add another server to the system, which consumes part of the client workload. Load balancing mechanisms distribute client workload equitably among back-end servers to improve overall system responsiveness. This master thesis analyses existing load balancing technologies and mechanisms. The MidArc middleware system is analysed and the architecture for the MidArc load balancing system is defined. The load balancing system is implemented and built into the MidArc middleware system. The controlling mechanisms for the load balancing system are defined and implemented. The architecture of the subsystem for installing new resources into the middleware system is defined. The subsystem for installing new resources is implemented and built into the MidArc middleware system. Experience gained in development of the load balancing system showed the benefits of adding such functionality to middleware systems.
