Abstract:
Grid systems become the common solutions supporting scientific researches, business analysis, entering even the world of entertainment. Modern grids should satisfy following requirements to be considered as useful and convenient tools: cost-effectiveness, performance, quality of service, reliability, security. The critical part of grid system is a communication network, responsible for proper and reliable data transfer between computing nodes. In case of grids where data transfer delays (QoS) and reliability are not crucial, public networks (usually in conjunction with VPN technology) are used. For better performance and stable communication parameters private wide area networks (WANs) are build and utilized in grid environments. WAN-based grid systems require specific designing methods in order to ensure the cost and QoS optimality. Some problems typical for wide area networks must be considered: topology of private WAN, capacity of channels, routing (flow assignment), allocation of computing nodes. In the paper the model of WAN-based grid system is presented and the cost minimizing and QoS ensuring algorithm is proposed. Both network optimization issues and distributed computing optimization issues are considered simultaneously. Algorithm may be useful as well for designing as optimizing of WAN-based grids.
