Abstract |
We develop an analytical model of the web proxy cache and obtain the hit ratio in terms of the incoming requests rate, replacement distribution and document’s modification rate. We choose a queuing network to evaluate the decrease of the response time. Numerical results show that securing a perfect coherency leads to performance degradation which could be significant in extreme cases. |
