Reddy         Filename : draft-skreddy-enp-protocol-00.txt         Pages : 23         Date : 19-May-00 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 A URL for this Internet-Draft is: <A href="http://www.ietf.org/internet-drafts/draft-skreddy-enp-protocol-00.txt">http://www.ietf.org/internet-drafts/draft-skreddy-enp-protocol-00.txt</A> Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then         "get draft-skreddy-enp-protocol-00.txt". A list of Internet-Drafts directories can be found in <A href="http://www.ietf.org/shadow.html">http://www.ietf.org/shadow.html</A> or <A href="ftp://ftp.ietf.org/ietf/1shadow-sites.txt">ftp://ftp.ietf.org/ietf/1shadow-sites.txt</A> Internet-Drafts can also be obtained by e-mail. Send a message to:         mailserv@ietf.org. In the body type:         "FILE /internet-drafts/draft-skreddy-enp-protocol-00.txt". 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. </DIV> <DIV>  <A href="http://www.ietf.org/internet-drafts/draft-skreddy-enp-protocol-00.txt">http://www.ietf.org/internet-drafts/draft-skreddy-enp-protocol-00.txt</A></DIV></BODY></HTML>
