Abstract
Network disconnections are automatically detected between a client application and a server When a disconnection is detected by either the client or server, a determination is made as to whether the disconnection is a temporary disconnection or a longer-lasting disconnection. While disconnected, attempts are made to automatically reconnect the client and server. During the disconnected period, a subset of communication functions remain operable. When the connection is restored, presence/availability information is automatically delivered to the client.
