<div class="sectionbody">
<div class="paragraph">
<p>An asynchronous operation is any interaction between two software entities where the conclusing action does not immediately follow the initiating action. There are a number of different models for Asynchronous Operations. This section attempts to describe someof the more common ones. An understanding of the scope of this space will help discuss and compare the alternatives OGC faces in asynchonous services.</p>
</div>
<div class="paragraph">
<p>Asynchronous operatations have three variables:</p>
</div>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>The overall pattern of behavior</p>
</li>
<li>
<p>How the two entities rendezvous</p>
</li>
<li>
<p>The criteria for selecting response messages</p>
</li>
</ol>
</div>
<div class="sect2">
<h3 id="_behavior_models"><a class="anchor" href="#_behavior_models"></a>2.1. Behavior Models</h3>
<div class="sect3">
<h4 id="_request_response"><a class="anchor" href="#_request_response"></a>2.1.1. Request-Response</h4>
<div class="paragraph">
<p>Request-Response is a synchronous behavior model. A request is issued by one entity and a response is provided in return. Asynchonous behaviors can best be understood in contrast to this model.</p>
</div>
</div>
<div class="sect3">
<h4 id="_delayed_response"><a class="anchor" href="#_delayed_response"></a>2.1.2. Delayed Response</h4>
<div class="paragraph">
<p>This model differs from Reqest-Response in that the immediate response is not the final response. Rather it acknowedges successful receipt of the request. The final response is to be delivered latter.</p>
</div>
</div>
<div class="sect3">
<h4 id="_standing_request"><a class="anchor" href="#_standing_request"></a>2.1.3. Standing Request</h4>
<div class="paragraph">
<p>A Standing Request is a variation of the Delayed Response pattern. While a Delayed Response performs a single operation, a Standing Request is active until instructed to stop.</p>
</div>
</div>
<div class="sect3">
<h4 id="_synchronization"><a class="anchor" href="#_synchronization"></a>2.1.4. Synchronization</h4>
<div class="paragraph">
<p>The Synchronization pattern supports a scenario where communication between the message producer and consumer is intermittent. When communication is possible, they perform whatever transactions are needed to synchronize their states, then establish a checkpoint for that state. Both parties can then continue to operate independently until the next synchronization opportunity arrives.</p>
</div>
</div>
<div class="sect3">
<h4 id="_publish_subscribe"><a class="anchor" href="#_publish_subscribe"></a>2.1.5. Publish-Subscribe</h4>
<div class="paragraph">
<p>The Publish-Subscribe model completely separates message producers and consumers. Potential consumers of messages create filtering criteria which describe the types of messages they wish to receive. They then "subscribe" to a Pub-Sub service with this filtering criteria. Producers of messages "publish" those messages to the Pub-Sub service along with a set of tags which describe each message. The Pub-Sub service evaluates the tags against the filtering criteria of all subscribers. The message is forwarded to all subscribers who’s criteria are met.</p>
</div>
<div class="paragraph">
<p>The "publish" operation follows the Request-Response pattern. The "subscribe" operation follows the Standing Request pattern.</p>
</div>
</div>
<div class="sect3">
<h4 id="_broadcast"><a class="anchor" href="#_broadcast"></a>2.1.6. Broadcast</h4>
<div class="paragraph">
<p>Broadcast is the simplest asynchronous pattern. The message producer simply sends the message to everyone. It is left up to the recipients to decide what to do with it.</p>
</div>
</div>
</div>
<div class="sect2">
<h3 id="_notification_and_alert"><a class="anchor" href="#_notification_and_alert"></a>2.2. Notification and Alert</h3>
<div class="paragraph">
<p>An inherent property of Asynchronus operations is that there is no persistent connection between the message producer and message receiver. Therefore, there must be a way for the message producer to re-establish a connection with the receiver in order to complete the transaction. There are a number of ways this is done.</p>
</div>
<div class="sect3">
<h4 id="_callback"><a class="anchor" href="#_callback"></a>2.2.1. Callback</h4>
<div class="paragraph">
<p>Callbacks can be viewed as mini-services who’s sole purpose is to receive an asychronous response. Information on how to access the callback is provided with the initial request. Message producers (or their agents) use this information deliver responses, typically using the Request-Response pattern.</p>
</div>
</div>
<div class="sect3">
<h4 id="_polling"><a class="anchor" href="#_polling"></a>2.2.2. Polling</h4>
<div class="paragraph">
<p>In polling the requesting entity checks on the status of their request on a recurring basis. Upon completion of the request, the requestor retrieves the result to complete the transaction.</p>
</div>
</div>
<div class="sect3">
<h4 id="_stored_response_queue"><a class="anchor" href="#_stored_response_queue"></a>2.2.3. Stored response queue</h4>
<div class="paragraph">
<p>A stored response queue is a service which holds responses to asynchoronous requests. The message producer simply leaves the response in the queue, and it’s up to the requestor to retrieve it.</p>
</div>
</div>
<div class="sect3">
<h4 id="_man_in_the_loop"><a class="anchor" href="#_man_in_the_loop"></a>2.2.4. Man in the Loop</h4>
<div class="paragraph">
<p>If all else fails, let the human do it. Many alternatives are available including instand messaging, e-mail, phone calls, even the Postal Service.</p>
</div>
</div>
</div>
<div class="sect2">
<h3 id="_filtering"><a class="anchor" href="#_filtering"></a>2.3. Filtering</h3>
<div class="paragraph">
<p>Filtering allows a message producer to identify the intended recipients of a message.</p>
</div>
<div class="sect3">
<h4 id="_event_rss_snmp"><a class="anchor" href="#_event_rss_snmp"></a>2.3.1. Event (RSS, SNMP)</h4>
<div class="paragraph">
<p>Event filtering specifies that a notification will be sent if certain conditions occure. For example, if the free space in a mail box drops below 10%.</p>
</div>
</div>
<div class="sect3">
<h4 id="_tags_jms"><a class="anchor" href="#_tags_jms"></a>2.3.2. Tags (JMS)</h4>
<div class="paragraph">
<p>Publish-Subscribe implementations typically define a set of topics (terms) which can be used to select messages for delivery. In the most basic case a recipient can only subscribe to topics. More capable systems may provide a simple query language to go with the topic vocabulary,</p>
</div>
</div>
<div class="sect3">
