A New Internet-Draft is available from the on-line Internet-Drafts
directories.

        Title : Event Notification Protocol - ENP
        Author(s) : S. Reddy
        Filename : draft-skreddy-enp-protocol-00.txt
        Pages : 23

As the complexity of distributed applications increases, an
increasing amount of processing is done using distributed processes,
which typically execute without the direct supervision of an end
user. The user must poll these processes periodically to check if
they are completed successfully or not. This polling results in
unnecessary wastage of network bandwidth as well as computing
resources. The user generally cannot see intermediate results or
progress reports for long running processes, they must wait till the
process is completely finished before viewing the results.
Thus the problem of monitoring events is central in distributed
applications and protocols. A repeated need in such applications is
receive notifications when a resource property value changes or
event state changes. Current database systems provides mechanisms
like constraints, triggers and active database rules. These
facilities provides an automated means to ensure the database
integrity or perform specific action when data changes. Need for
such kind of requirement is fundamental is network applications

In the body type:

NOTE: The mail server at ietf.org can return the document in
        MIME-encoded form by using the "mpack" utility. To use this
        feature, insert the command "ENCODING mime" before the "FILE"
        command. To decode the response(s), you will need "munpack" or
        a MIME-compliant mail reader. Different MIME-compliant mail readers
        exhibit different behavior, especially when dealing with
        "multipart" MIME messages (i.e. documents which have been split
        up into multiple messages), so check your local documentation on
        how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
