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.
