<p>Stream management implements these features using short XML elements at the root stream level. These elements are not "stanzas" in the XMPP sense (i.e., not &IQ;, &MESSAGE;, or &PRESENCE; stanzas as defined in <cite>RFC 6120</cite>) and are not counted or acked in stream management, since they exist for the purpose of managing stanzas themselves.</p>
|
||||
<p>Stream management is used at the level of an XML stream. To check TCP connectivity underneath a given stream, it is RECOMMENDED to use whitespace keepalives (see <cite>RFC 6120</cite>), &xep0199;, or TCP keepalives. By contrast with stream management, &xep0079; and &xep0184; define acks that are sent end-to-end over multiple streams; these facilities are useful in special scenarios but are unnecessary for checking of a direct stream between two XMPP entities.</p>
|
||||
<p>Note: Stream Management can be used for server-to-server streams as well as for client-to-server streams. However, for convenience this specification discusses client-to-server streams only. The same principles apply to server-to-server streams. (In this document, examples prepended by "C:" are sent by a client and examples prepended by "S:" are sent by a server.)</p>

<p>If the client wants to be allowed to resume the stream, it includes a boolean 'resume' attribute, which defaults to false &BOOLEANNOTE;. For information about resuming a previous session, see the <link url='#resumption'>Resumption</link> section of this document.</p>
|
||||
<p>The <enable/> element MAY include a 'max' attribute to specify the client's preferred maximum resumption time in seconds.</p>
|
||||
<p>Upon receiving the enable request, the server MUST reply with an <enabled/> element or a <failed/> element qualified by the 'urn:xmpp:sm:3' namespace. The <failed/> element indicates that there was a problem establishing the stream management "session". The <enabled/> element indicates successful establishment of the stream management session.</p>

<p>The client MUST NOT attempt to negotiate stream management until it is authenticated; i.e., it MUST NOT send an <enable/> element until after authentication (such as SASL, &xep0078; or &xep0220;) has been completed successfully.</p>

<p>When an <r/> element ("request") is received, the recipient MUST acknowledge it by sending an <a/> element to the sender containing a value of 'h' that is equal to the number of stanzas handled by the recipient of the <r/> element. The response SHOULD be sent as soon as possible after receiving the <r/> element, and MUST NOT be withheld for any condition other than a timeout.

<p class='def'><strong>Definition:</strong> The 'id' attribute defines a unique identifier for purposes of stream management (an "SM-ID"). The SM-ID MUST be generated by the server. The client MUST consider the SM-ID to be opaque and therefore MUST NOT assign any semantic meaning to the SM-ID. The server MAY encode any information it deems useful into the SM-ID, such as the full JID &LOCALFULL; of a connected client (e.g., the full JID plus a nonce value). Any characters allowed in an XML attribute are allowed. The SM-ID MUST NOT be reused for simultaneous or subsequent sessions (but the server need not ensure that SM-IDs are unique for all time, only for as long as the server is continuously running). The SM-ID SHOULD NOT be longer than 4000 bytes.</p>

<p>Note: The order of events might differ from those shown above, depending on when the server offers the SM feature, whether the client chooses STARTTLS, etc. Furthermore, in practice server-to-server streams often do not complete SASL negotiation or even TLS negotiation. The foregoing text does not modify any rules about the stream negotiation process specified in <cite>RFC 6120</cite>. However, since stream management applies to the exchange of stanzas (not any other XML elements), it makes sense for the server to offer the SM feature when it will be possible for the other party to start sending stanzas, not before. See also &xep0170;.</p>

<p>To request resumption of the former stream, the client sends a <resume/> element qualified by the 'urn:xmpp:sm:3' namespace. The <resume/> element MUST include a 'previd' attribute whose value is the SM-ID of the former stream and MUST include an 'h' attribute that identifies the sequence number of the last handled stanza sent over the former stream from the server to the client (in the unlikely case that the client never received any stanzas, it would set 'h' to zero).</p>

<section2 topic='Efficient Acking Scenario' anchor='scenarios-efficient'>
|
||||
<p>The basic acking scenario is wasteful because the client requested an ack for each stanza. A more efficient approach is to periodically request acks (e.g., every 5 stanzas). This is shown schematically in the following pseudo-XML.</p>

<p>In particular, on mobile networks, it is advisable to only request and/or send acknowledgements when an entity has other data to send, or in lieu of a whitespace keepalive or XMPP ping (XEP-0199).</p>
