Summary

Our analysis shows that notification messages are small, popular documents account for a significant fraction of the messages, and there exists a high degree of sharing in geographical regions. System designers need to develop transport protocols that can send such messages in a reliable, efficient and secure manner. For example, an overlay network consisting of geographically placed caches along with application-level multicast can reduce the total network bandwidth requirements and server load. We also observed that there is a significant variation in clients' usage of notification services. Service providers can design pricing plans according to the needs of the clients and also specialize content based on geographical location.
