Abstract
A plurality of cache servers, connected to a packet forwarding apparatus, forwarding a packet transmitted and received between a storage apparatus that holds a content under management in store and a user terminal, temporarily holds at least part of the content under management in store. A controller decides an on-screen resolution at the terminal, based on information contained in a content request message from the terminal, and selects a cache server that holds a content of the on-screen resolution in store. The controller instructs the selected cache server to deliver the content. The cache server instructed calculates a bit rate based on a signal received from the terminal. The cache server reads content from the terminal, which is to have the on-screen resolution and a bit rate not higher than the calculated bit rate. The content is stored in a packet and transmitted, then delivered without reducing the user's QoE.
