-ryu.app.ofctl
-*************
-
-ryu.app.ofctl provides a convenient way to use OpenFlow messages
-synchronously.
-
-OfctlService ryu application is automatically loaded if your
-Ryu application imports ofctl.api module.
-
-Example::
-
-    import ryu.app.ofctl.api
-
-OfctlService application internally uses OpenFlow barrier messages
-to ensure message boundaries.  As OpenFlow messages are asynchronous
-and some of messages does not have any replies on success, barriers
-are necessary for correct error handling.

+****************
+Ryu L2 isolation
+****************
+This section describes how Ryu cooperates with Openstack Quantum and
+how its L2 isolation works.
+
+Overview
+========
+Ryu provides REST API by which Quantum server tells necessary informations.
+Quantum Server manages the association networks(uuid) to actual key value in
+addition to normal Quantum management informations.
+(Here key value is an integer for VLAN ID, GRE key and so on.
+The quantum only have to know the range of key which depends on the isolation
+technology. For example, 12 bit in VLAN case, 24 bit in GRE case.)
+Quantum Ryu plugin doesn't know about what technology Ryu uses for L2
+isolation.
+
+  .. image:: /images/internal-quantum-overview.png
+
+Quantum doesn't necessarily knows all the informations Ryu needs like
+mac address attached to the interface. Ryu can gather those informations
+by accessing directly to OVSDB. When tunnel ports on OVS needs to be created
+on compute-node, Ryu will directly accesses to OVSDB and creates/deletes
+ports.
+
+
+Cooperate with Openstack Quantum
+================================
+Ryu reacts to Qauntnum events, compute-node boots up, network
+creation/deletion, and VM instance creation/deletion.
+When VM instance is created, corresponding quantum port is created.
+
+compute-node boot up
+--------------------
+When a compute note boots up, minimal initalization work is done by
+Ryu-quantum-agent which tell necessary informations to Ryu.
+Then Ryu set up OVS such that OVS connects to Ryu via OpenFlow.
+There are 2 steps of OVS initialization. By agent and by Ryu.
+This is to keep Ryu agent logic minimal and independent from what actual Ryu
+needs to set. Even if Ryu is enhanced for new feature and some additional
+configuration to OVS is needed (for example multi-controller for HA),
+ryu agent doesn't need to be modified due to 2 step initialization.
+
+  .. image:: /images/internal-quantum-bootup.png
+
+network creation
+----------------
+When network is created, quantum Ryu plugin assigns Key value to
+a created network, and tell the association to Ryu
+
+  .. image:: /images/internal-quantum-network-creation.png
+
+VM instance creation
+--------------------
+When VM instance is created, quantum port is created. Quantum Ryu
+plugin tells the association of (network uuid, port uuid) to Ryu, and
+then OVS port is created.  Ryu finds the port creation via OpenFlow
+and get the information of the created port for (port uuid, attached
+mac address) via OVSDB protocoal, and then sets up network
+configuration to OVS.
+
+  .. image:: /images/internal-quantum-instance-create.png
+
+quantum_adapater RyuApp
+-----------------------
+This application watches port creation/deletion by OF protocol.
+When it detects the creation of ports, it tries to retrieve related
+informations(port uuid, mac address) by OVSDB protocol,
+tries to determine if the port corresponds to Qauntnum VM port, and then
+stores those informations into the in-memory, which generates the event of
+VMPort creation. Then Ryu app of isolation (simple_vlan or gre_tunnel)
+will be notified.
+
+live-migration
+--------------
+live-migration is popular feature with virtualization, so as OpenStack.
+As of this writing, there is no hooks in quantum. So no notification/callback
+are triggered when live-migration starts/on-going/ends/error-abort.
+Traditional live-migration uses GARP to tell switches the used mac address
+is moved.
+
+  .. image:: /images/internal-live-migration.png
+
+VLAN
+====
+OVS supports port vlan with setting tag value in OVSDB.
+Ryu utilizes it for L2 isolation.
+
+simple_vlan RyuApp
+------------------
+When port is created, it sets tag value to key assigned to a given network uuid.
+And sets flow entry to output:normal.
+
+live-migration
+--------------
+As flows includes output:normal action, packets are processed by
+OVS builtin mac-learning.
+
+#. When destination VM port is created, same rule is inserted on OVS
+   on the destination.
+   But the port on the destination is not used until the first GARP packet
+   is sent
+#. When VM is resumed on the destination, a GARP packet is sent.
+   Then, mac learning tables on each switch are updated.
+   So the port on the source will be unused.
+#. When the VM on the source is destroyed, the port on the source is also
+   destroyed.
+
+
+GRE tunneling
+=============
+OVS supports tunneling and Ryu utilizes it for L2 isolation as follows.
+
+  .. image:: /images/internal-gre-tunnel.png
+
+tunnel_port_updator RyuApp
+--------------------------
+This application watches the VM port creation/deletion, and creates/deletes
+tunnel port on OVS when necessary.
+That is, it creates tunnel port between compute-nodes which have VMs of same
+tenant. it deletes tunnel ports when compute-nodes have no VMs of same
+tenant.
+
+gre_tunnel RyuApp
+-----------------
+This application watches VM/tunnel port creation/deletion, and
+installs/removes flow entries based on port creation/deletion.
+
+Flow Entries
+------------
+Ryu installs following flow entries.
+
+  .. image:: /images/internal-quantum-gre-flow-table.png
+
+live-migration
+--------------
+As flows are aware of mac address of each ports, Ryu updates flow table
+for live-migration on each compute-nodes.
+When the port of same mac address is added on another compute-node,
+Ryu installs flows that duplicates packet so that packets destined to
+the mac address will be duplicated and sent to both ports.
+GARP from hypervisor isn't used.
+
+  .. image:: /images/internal-tunnel-live-migration-before.png
+  .. image:: /images/internal-tunnel-live-migration-during.png
+  .. image:: /images/internal-tunnel-live-migration-after.png
+
+Mac address based L2 isolation
+==============================
+Ryu also supports mac address based L2 isolation.
+In this case key isn't used.
+
+mac learing
+-----------
+When VM sends packets, Ryu determins network uuid from OVS port and then
+associates src mac address to network uuid.
+
+   .. image:: /images/mac-learning.png
+
+
+packet filtering(L2 unicast case)
+---------------------------------
+* When VM sending L2-unicast packet, Ryu checks if the destination mac
+  address belongs to the same netowrk id of the source mac address which
+  is same to the network uuid that the OVS port is associated to.
+* If no, the packet is dropped.
+* If yes, send the packet is sent to ports which belongs to the same
+  network uuid and external port.
+
+   .. image:: /images/filtering-outgoing.png
+   .. image:: /images/filtering-incoming.png
+
+
+packet filtering(L2 broadcast case)
+-----------------------------------
+* When VM sending L2-broadcast/multicaset packet, Ryu checks if the source
+  mac address.
+* send the packet to all external ports and all OVS ports that belongs
+  to the same network uuid of the source mac address.
+* When receiving broacast/multicast packet from the external ports,
+  Ryu checks if the source mac address belongs to known network uuid.
+
+   * If yes, send the packet to the external ports except incoming one
+     and the all OVS ports that belongs to the network uuid
+   * if no, drop the packet.
+
+   .. image:: /images/filtering-broadcast.png
+
+live-migration
+--------------
+As of this writing, simple isolation doesn't support live-migration.

-
-Example
-=======
-
-The following simple code creates a BGP instance with AS number 64512
-and Router ID 10.0.0.1. It tries to establish a bgp session with a
-peer (its IP is 192.168.177.32 and the AS number is 64513). The
-instance advertizes some prefixes.

-Basic Usage
-===========
-
-1. Instantiate :py:mod:`ryu.lib.ovs.vsctl.VSCtl`.
-
-2. Construct commands with :py:mod:`ryu.lib.ovs.vsctl.VSCtlCommand`.
-   The syntax is almost the same as ovs-vsctl_ command.
-
-3. Execute commands via :py:mod:`ryu.lib.ovs.vsctl.VSCtl.run_command`.

-Example
--------
-
-.. code-block:: python
-
-    from ryu.lib.ovs import vsctl
-
-    OVSDB_ADDR = 'tcp:127.0.0.1:6640'
-    ovs_vsctl = vsctl.VSCtl(OVSDB_ADDR)
-
-    # Equivalent to
-    # $ ovs-vsctl show

-
-Introduction
-============
-
-Ryu OVSDB Manager library allows your code to interact with devices
-speaking the OVSDB protocol. This enables your code to perform remote
-management of the devices and react to topology changes on them.
-
-Please note this library will spawn a server listening on the port 6640 (the
-IANA registered for OVSDB protocol), but does not initiate connections from
-controller side.
-Then, to make your devices connect to Ryu, you need to tell the controller IP
-address and port to your devices.
-
-.. code-block:: bash
-
-    # Show current configuration
-    $ ovs-vsctl get-manager
-
-    # Set manager (controller) address
-    $ ovs-vsctl set-manager "tcp:127.0.0.1:6640"
-
-    # If you want to specify IPv6 address, wrap ip with brackets
-    $ ovs-vsctl set-manager "tcp:[::1]:6640"
-
-Also this library identifies the devices by "system-id" which should be unique,
-persistent identifier among all devices connecting to a single controller.
-Please make sure "system-id" is configured before connecting.
-
-.. code-block:: bash
-
-    # Show current configuration
-    $ ovs-vsctl get Open_vSwitch . external_ids:system-id
-
-    # Set system-id manually
-    $ ovs-vsctl set Open_vSwitch . external_ids:system-id=<SYSTEM-ID>
-
-Example
-=======
-
-The following logs all new OVSDB connections in "handle_new_ovsdb_connection"
-and also provides the API "create_port" for creating a port on a bridge.
