<section xml:id="Theory">
<title>Theory of Operation</title>
<para>This section presents the objects and semantics of
Quantums logical model.</para>
<para>Quantum abstracts the physical implementation of the
network, allowing plugins to configure and manage
physical resources. Quantum is a standalone service,
in that it requires no other project within OpenStack
to function correctly.</para>
<para>Further Quantum is agnostic to the entities it
allows to connect. While we anticipate Nova instances
will be a heavy user of Quantum, any entity can make
use of any Quantum created network so long as it
provides an appropriate interfaces for exposing VIFs
to Quantum itself.</para>
<para>Virtual Interfaces (VIF) in the logical model are
analogous to physical network interface cards (NICs).
VIFs are typically owned a managed by an external
service; for instance when Quantum is used for
building OpenStack networks, VIFs would be created,
owned, and managed in Nova. VIFs are connected to
Quantum networks via ports. A port is analogous to a
port on a network switch, and it has an administrative
state. Quantum API allows for controlling the
administrative state of the port, which can be either
'DOWN' or 'ACTIVE'.</para>
<para>When a VIF is attached to a port the Quantum API
creates an attachment object, which specifies the fact
that a VIF with a given identifier is plugged into the
port.</para>
<para>The Quantum plugin is responsible for managing
virtual and/or physical network switches to implement
the network forwarding connectivity described by the
Quantum networks, ports, and attachments.</para>
<para>VIFs attached to ACTIVE ports are required to have
access to the L2 broadcast domain defined by the
network where they are attached. Each VIF shall be
capable of exchanging traffic with all other entities
attached through ACTIVE ports.</para>

<title>Concepts</title>
<para>To use the Quantum API effectively, developers should
understand the concepts introduced in this chapter.</para>
<section xml:id="Network">
<title>Network</title>
<para>Each tenant can define one or more networks. A
network is a virtual isolated layer-2 broadcast domain
reserved to the tenant. A tenant can create several
ports for a network, and plug virtual interfaces into
these ports.</para>
</section>
<section xml:id="Port">
<title>Port</title>
<para>A port represents a virtual switch port on a logical
network switch where all the interfaces attached to a
given network are connected.</para>
<para>A port has an administrative state which is either
'DOWN' or 'ACTIVE'. Ports which are administratively
down will not be able to receive/send traffic.</para>
</section>
<section xml:id="Attachment">
<title>Attachment</title>
<para>An attachment represents an interface plugged into a
logical port. At any time at most one attachment can
be plugged into a given port.</para>
<para>An attachment typically identified a virtual network
interface. Network interfaces are typically defined in
an external services which uses Quantum, for instance
the OpenStack Compute service, Nova.</para>

</chapter>
<chapter xml:id="General_API_Information-d1e436">
<title>General API Information</title>
<para>The OpenStack Quantum API is defined as a ReSTful HTTP
service. The API takes advantage of all aspects of the
HTTP protocol (methods, URIs, media types, response codes,
etc.) and providers are free to use existing features of
the protocol such as caching, persistent connections, and
content compression among others. For example, providers
who employ a caching layer may respond with a 203 when a
request is served from the cache instead of a 200.
Additionally, providers may offer support for conditional
&GET; requests using ETags, or they may send a redirect in
response to a &GET; request. Clients should be written to
account for these differences.</para>
<section xml:id="Authentication-d1e444">
<title>Authentication</title>
<para>The current version of the OpenStack Quantum service
does not require that each request will include the
credentials of the user submitting the request.</para>
<para>However, Quantum deployments can support several
authentication schemes (OAuth, Basic Auth, Token). The
authentication scheme used is determined by the
provider of the Quantum service. Please contact your
provider to determine the best way to authenticate
against this API.</para>
<para>Ideally, middleware modules for Authentication
and/or Authorization should be inserted in the first
stages of the Quantum pipeline (available in
<code>etc/quantum.conf</code>).</para>
<note>
<para>Some authentication schemes may require that the
API operate using SSL over HTTP (HTTPS).</para>
</note>
</section>
<?hard-pagebreak?>
<section xml:id="URI_structure">
<title>URI structure</title>
<para>Each request to the OpenStack Quantum API must refer
to a specific version of the API itself, and it must
also identify the tenant for which the request is
being sent.</para>
<para>This information is specified in the URI. The URI
for each request to the OpenStack Quantum API should
be prefixed with the API version identifier and the
tenant identifier, as follows:</para>
<para>
<code>/{Quantum-version}/tenants/{tenant-id}/{Quantum-API-entity}</code>
</para>
<para>As an example, the following URI represents a
request for retrieving all the networks configured for
the tenant "ABC" using the 1.0 API.</para>
<para>
<code>/v1.0/ABC/networks</code>
</para>
</section>
<section xml:id="Request_Response_Types">
<title>Request/Response Types</title>
<para>The OpenStack Quantum API supports both the JSON and
XML data serialization formats. The format for both
the request and the response can be specified either
using the <code>Content-Type</code> header, the
<code>Accept</code> header or adding an
<code>.xml</code> or <code>.json</code> extension
to the request URI.</para>
<para>If conflicting formats are specified in headers
and/or format extensions, the latter takes precedence.
XML is currently the default format for both requests
and responses.</para>

<section xml:id="Async_behaviour">
<title>Asynchronous Behavior by Quantum Plugins</title>
<para>The Quantum API presents a logical model of network
connectivity consisting of networks, ports, and
attachments. It is up to the Quantum plugin to
communicate with all managed virtual and/or physical
switches to ensure that these devices implement packet
forwarding behavior consistent with the logical
model.</para>
<para>The plug-in task of mapping from the logical model
to the physical world might happen asynchronously.
This means that when an API client modifies the
logical model using an HTTP POST, PUT, or DELETE, the
API call may return prior to the plugin performing any
modifications to underlying virtual and/or physical
switching devices. The only guarantee an API client
has is that all subsequent API calls will properly
reflect the changed logical model.</para>
<para>As a concrete example, consider the case where a
client uses an HTTP PUT to set the attachment for a
port. There is no guarantee that packets sent by the
interface named in the attachment will be forwarded
immediately once the HTTP call returns. However, there
is a guarantee that a subsequent HTTP GET to view the
attachment on that port would return the new
attachment value.</para>
<note>
<para>Future versions of the API may expose a notion
of an "operational status" on a logical entity
like a network or port.</para>
<para>This would indicate whether the Quantum plugin
had successfully configured virtual and/or
physical switches in order to implement the
network connectivity described by that element of
the logical model.</para>
<para>For example, a port might have an operational
status of <code>"DOWN"</code> because the VM
interface specified as an attachment was not
currently running on any physical server.</para>
</note>
</section>
<section xml:id="Versions">
<title>Versions</title>
<para>The Quantum API uses a URI based versioning scheme.
The first element of the URI path contains the target
version identifier. <example>
<title>Request with URI versioning</title>
<literallayout class="monospaced">
GET /v1.0/tenants/tenantX/networks HTTP/1.1

<section xml:id="Extensions">
<title>Extensions</title>
<para>The Quantum API is extensible. Extensions serve
several purposes:</para>
<itemizedlist spacing="compact">
<listitem>
<para>They allow the introduction of new features
in the API without requiring a version change;
</para>
</listitem>
<listitem>
<para>They allow the introduction of vendor
specific niche functionality</para>
</listitem>
<listitem>
<para>They act as a proving ground for
experimental functionalities which might be
included in a future version of the API.
</para>
</listitem>
</itemizedlist>
<para>Applications can programmatically determine what
extensions are available by performing a &GET; on the
<code>/v1.0/extensions</code> URI. Note that this
is a versioned request &mdash; that is, an extension
available in one API version may not be available in
another.</para>
<example>
<title>Extensions Response: XML</title>
<programlisting language="xml"><?db-font-size 90%?><xi:include href="samples/extensions.xml" parse="text"/></programlisting>
</example>
<?hard-pagebreak?>
<example>
<title>Extensions Response: JSON</title>
<programlisting language="json"><?db-font-size 90%?><xi:include href="samples/extensions.json" parse="text"/></programlisting>
</example>
<para>Extensions may also be queried individually by their
unique alias by performing a &GET; on the
<code>/v1.0/extensions/alias_name</code>. This
provides the simplest method of checking if an
extension is available as an unavailable extension
will issue an itemNotFound (404) response.</para>
<note>
<para>Existing core API resources can be extended with
new actions or extra data in request/response of
existing actions. Further new resources can also
be added as extensions. Extensions usually have
vendor specific tags that prevent clash with other
extensions. Availability of an extension will vary
with deployments and the specific plugin in use.
</para>
</note>
<important>
<para>Applications should be prepared to ignore
response data that contains extension elements.
Applications should also verify that an extension
is available before submitting an extended
request.</para>
</important>
</section>
<?hard-pagebreak?>
<section xml:id="Faults">
<title>Faults</title>
<para>When an error occurs at request time, the system
will return an HTTP error response code denoting the
type of error. The system will also return additional
information about the fault in the body of the
response.</para>
<example>
<title>"Network not found" fault Response
(XML)</title>
<programlisting language="xml"><xi:include href="samples/fault.xml" parse="text"/>
</programlisting>
</example>
<example>
<title>"Network not found" fault Response
(XML)</title>
<programlisting language="json"><xi:include href="samples/fault.json" parse="text"/> </programlisting>
</example>
<para>The error code is returned in the body of the
response for convenience. The message section returns
a human-readable message that is appropriate for
display to the end user. The detail section is
optional and may contain information&mdash;for
example, a stack trace&mdash;to assist in tracking
down an error.</para>
<para>The root element of the fault (e.g. networkNotFound)
may change depending on the type of error. The
following is a list of possible elements along with
their associated error codes.</para>

<para>This operation sets the administrative state for
a port. Currently Quantum recognizes two port
states: <code>DOWN</code> and <code>ACTIVE</code>.
In the <code>DOWN</code> state a port will not
provide connectivity to the network.</para>
<para>This feature allows the tenant the ability to
take entities offline without affecting the
logical topology.</para>
<para>The operation will return the
<code>RequestedStateInvalid</code> error code
if the specified administrative state is not
either <code>DOWN</code> or
<code>ACTIVE</code>.</para>
<para>The operation's request body must contain a Port
object with the new administrative state for the
port.</para>
