In server migration service (SMS), computers called work places (WPs) are deployed at various locations in a network, and virtual servers for network applications (NW-Apps) may migrate between WPs towards the clients of the NW-App to achieve better QoS. In SMS, an SMS provider tries to provide an NW-App provider with a certain level of QoS that they agree upon, and if the SMS provider fails, it pays penalty (e.g., reimbursement of a part of service charges to users) depending on the degree and length of the QoS violation. Thus, the SMS provider is incentivized to migrate servers between WPs to satisfy the agreed-upon QoS level to reduce the penalty. On the other hand, an SMS provider also needs to be moderate in performing server migrations to avoid degradation of network QoS (i.e., QoS of background traffic) caused by server migrations. This paper formulates an integer-programming model for the off-line server location decision (i.e., when and to which WP servers should migrate) where the penalty associated with NW-App’s QoS violations is minimized, keeping the number and distance of server migrations below a given level. This paper also compares the minimum penalty obtained through solving the integer-programming model against the penalty obtained with a greedy on-line server locations decision algorithm, which migrates a server to a WP that minimizes the current penalty with no consideration of the penalty that will arise in the future. Numerical examples show that the integer-programming model achieves 36% to 49% lower penalty than the greedy algorithm when the degradation of network QoS is little acceptable. |
