If this header is not-received, the requesting client is assumed to follow normal Gnutella-behavior in the event of a busy response.-</p><p>If there is an upload "slot" available, the download begins as-normal with a 200 or 206 response. If not, the request is placed at-the end of the queue and a 503 response is returned with the-additional X-Queue header, of the form:-</p>-<pre> X-Queue: position=2,length=5,limit=4,pollMin=45,pollMax=120-</pre>-<p>Clearly this header includes several pieces of information separated-by commas in the usual manner. Every part is optional, and if-desired it can be broken into multiple headers, etc. Anyway, the-parts:-</p><p>The "position" key indicates the request's position in the queue,-where position 1 is next in line for an available slot.-The "length" key indicates the current length of the queue, for-informational purposes. Likewise the "limit" key specifies the-number of concurrent uploads allowed. All of this information is-completely optional, and is only used for display within the client.-</p><p>Finally, "pollMin" and "pollMax" provide hints to the requesting-client as to how often it should re-request the file (in seconds).-Requesting more often than pollMin will be seen as flooding, and-cause a disconnection. Failing to issue a request before pollMax-will be seen as a dropped connection. Once again these items are-optional and need not be present in the header, in which case a-default retry interval can be used.-</p><p>Upon receiving a 503 response with an X-Queue header, the downloader-displays any information it received to the user and waits for an-appropriate period before reissuing the request. The default retry-period is adjusted to lie comfortably within pollMin and pollMax if-they were present in the response, which allows a particularly busy-server to adjust its parameters and reduce load. When the request-finally succeeds, it does so in the normal way.-</p><p>This solution brings the following properties :-</p>-<ul><li> The downloader can see their place in the queue change as they move towards position #1, so even if the queue is long, at least progress can be observed. Important not to underestimate the value of showing visible progress to the user.-</li></ul>-<ul><li> Because the HTTP request is reissued periodically, the client is able to request the most appropriate "Range" each time. It also allows active propagation of alternate location headers in both directions, and in the case of a partial file gives the requesting client an up-to-date picture of the available ranges.-</li></ul>-<ul><li> By requiring the requesting client to maintain a connection, there is no need to hold open upload positions for a request that may never come. If the client is no longer interested in downloading from this source (found other sources, etc), it can close the connection immediately.-</li></ul>-<p>If the requesting client issues a request for a different file while-it is in a queued state, it is shifted back to the end of the queue.-It MUST continue to request the same file in order to hold the-position.-</p><p>When a successful partial request completes, the client is allowed-to make an additional request without being shifted to the end of-the queue. This allows clients to perform fixed block size / chunking-downloads without the risk of losing their position.-</p><p>The queue has a maximum length, and any requests which would not fit-within it are sent a standard, non-queued 503.-</p><p>Upload queues represent an important step for the evolution of-Gnutella because they reward users who have waited for a file, rather-than a "luck of the draw" approach which (if anything) rewards users-who abuse the system by requesting too often, etc. It is also much-more satisfying for a user to see a decrementing queue position which-assures that progress is being made, rather than a seemingly-never-ending stream of busy messages.-[TODO: put a word about the controversy. This paragraph above seems-too optimistic ?]-</p><p>This mechanism can be extended to provide more optimised performance:-</p>-<ul><li> The pollMin and pollMax time variables can be made proportional to the position within the queue. As a request moves closer to the head of the queue, the polling times can be reduced. This provides the requesting party with a finer precision update, and reduces or eliminates any gap in transmission when moving from the head of the queue into an active transfer state.-</li></ul>-<ul><li> Query-hit output MAY be adjusted based on the state of the upload queues -- for example, if no queue positions are available, it may be prudent to reduce the output of query hits, with the goal of reducing the number of new upload requests which could not be accepted.-</li></ul>-<p><a href="/index.php?title=Metadata_Extension" title="Metadata Extension"><< Metadata Extension</a> | <a href="/index.php?title=Link_Compression_Extension" title="Link Compression Extension">Link Compression Extension >></a> | <a href="/index.php?title=Main_Page" title="Main Page">Main Page</a>-</p>-<!-- Saved in parser cache with key wikidb:pcache:idhash:957-1!1!0!1!0!1!0!!en and timestamp 20061006081105 -->-<div class="printfooter">-Retrieved from "<a href="http://www.the-gdf.org/index.php?title=Active_Queuing_Extension">http://www.the-gdf.org/index.php?title=Active_Queuing_Extension</a>"</div>- <!-- end content -->- <div class="visualClear"></div>- </div>- </div>- </div>- <div id="column-one">- <div id="p-cactions" class="portlet">- <h5>Views</h5>- <ul>- <li id="ca-nstab-main"- class="selected" ><a href="/index.php?title=Active_Queuing_Extension">Article</a></li><li id="ca-talk"- ><a href="/index.php?title=Talk:Active_Queuing_Extension">Discussion</a></li><li id="ca-viewsource"- ><a href="/index.php?title=Active_Queuing_Extension&action=edit">View source</a></li><li id="ca-history"- ><a href="/index.php?title=Active_Queuing_Extension&action=history">History</a></li> </ul>- </div>- <div class="portlet" id="p-personal">- <h5>Personal tools</h5>- <div class="pBody">- <ul>- <li id="pt-login"><a href="/index.php?title=Special:Userlogin&returnto=Active_Queuing_Extension">Create an account or log in</a></li> </ul>- </div>- </div>- <div class="portlet" id="p-logo">- <a style="background-image: url(/skins/common/images/wiki.png);"- href="/index.php?title=Main_Page"- title="Main Page"></a>- </div>- <script type="text/javascript"> if (window.isMSIE55) fixalpha();

These </i>-so-called Gnutella servents perform tasks normally associated with both-clients and servers. They provide client-side interfaces through which-users can issue queries and view search results, while at the same time-they also accept queries from other servents, check for matches against-their local data set, and respond with applicable results. Due to its-distributed nature, a network of servents that implements the Gnutella-protocol is highly fault-tolerant, as operation of the network will not-be interrupted if a subset of servents goes offline.<i> - Philippe Verdy </i>-</p><p>This document is intended for readers with a fair knowledge of-network programming but does not require any previous Gnutella-experience.

These were often called-"hostcaches". However hostcaches are not used anymore.-</p><p>To connect to the Gnutella network, a servent needs to find-and store hosts' addresses. There are four ways by which a servent may-get hosts' addresses:-</p>-<ol><li> Calling a GWebCache-</li><li> Storing hosts' addresses read from X-Try and X-Try-Ultrapeers headers during handshakes (whether the handshake was successful or not).-</li><li> Storing hosts' addresses in pong messages (after at least one connection is established with the GNet).-</li><li> Storing hosts' addresses read from QueryHit messages (after a minimum of two connections are established with the GNet).

In most cases, it is not needed to query a-GWebCache more than once per session. This means, notably, that
