Abstract
A method and system for sending notifications from servers of a server pool to clients is provided. The notification system determines when an in-band notification is to be sent to clients. The notification system identifies a distinguished server for each client that is to send the in-band notification to that client. The notification system then sends an out-of-band notification to the distinguished server of each client indicating that an in-band notification is to be sent to the client. When the distinguished server receives the out-of-band notification, the distinguished server then sends an in-band notification to the client.
