A resource lending control apparatus stores an assignment time and a deletion time in association with each other for each customer. The assignment time indicates a time for assigning an application used by each customer to provide a service to a server. The deletion time indicates a time for deleting the application from the server. The resource lending control apparatus calculates a lendable period of a remaining fixed resource of a lending customer by subtracting the deletion time and the assignment time of the lending customer from a remaining fixed period. The resource lending control apparatus calculates a total borrowing period, i.e., a period during which a borrowing customer is to use a borrowed resource, by adding the deletion time and the assignment time of the borrowing customer to a borrowing request period. Then, the resource lending control apparatus determines whether the calculated total borrowing period is covered by the calculated lendable period to determine to lend the remaining fixed resource.

Every time a packet is received from a server, a communication performance measuring equipment transmits/receives a predetermined control packet to/from a client and a branching node, respectively, thereby collecting information about communication environment. Based on the information and a predetermined delay model, a delay time in delivering the same packet from the server to the client is estimated, and, according to the delay time, transmission timing of an acknowledge packet in response to the received packet is controlled. Thus, it is possible to accurately measure communication performance between an arbitrary client and an arbitrary server, no matter where the communication performance measuring equipment is physically arranged.

An instruction for transformation processing of an image is detected. An instruction for specifying a targeted image which will be the object of transformation processing is detected. An instruction for specifying a fixed point of the image without changing the position thereof, independent of transformation processing, is detected. Then, the instructed transformation processing is executed on the targeted image. The targeted image is displayed such that the fixed points of the targeted image before/after image processing are matched.
