Cooperative caching scheme based on the minimization of total cost for P2P caches
To reduce the total cost of P2P cache system, a cooperative cache scheme based on the minimization of total cost is proposed. In the scheme, delivery cost and storage cost are taken into account, and inter-ISP cost, popularity, file size, storage cost are used to evaluate each object's caching...

description | To reduce the total cost of P2P cache system, a cooperative cache scheme based on the minimization of total cost is proposed. In the scheme, delivery cost and storage cost are taken into account, and inter-ISP cost, popularity, file size, storage cost are used to evaluate each object's caching gain value, which is a new concept defined to estimate the benefits of storing or replacing an object. When a replacement is needed, the objects with the minimum caching gain value will be evicted. Simulation results show that the proposed scheme can effectively reduce the total cost of P2P cache system. |
