摘要：Recently, huge number of e-mails is sent and received. These e-mails are classified into spam and non spam ones which are processed with the same priority. To guarantee a higher priority service to non-spam e-mails than that is provided to spam e-mails, a two-priority queue scheme was proposed. There are some drawbacks in the two-priority queue scheme such as it fails to provide a Quality of Service (QoS) in case of network bottlenecks. In this paper, an algorithm for servicing non-spam e-mails with high probability is proposed. Markov chain is used to analyze the servicing probability of e-mails in case of two and three priority queue schemes. Results proved that the three-queue scheme provides a higher probability service to the most important non spam e-mails than that is provided to the same class in case of the two-queue scheme.
