Brandon Heller bb697af959 Spec: remove multi_phy_tx spec text and capability bit 
This flag was added on March 3, 2008 to comply with a specific vendor's
hardware limitations.  This vendor is out of business, and with the
assumption of a software datapath backup, it is unlikely that a switch
would be unable to support sending to a physical port and the controller
simultaneously.

This commmit removes the corresponding spec text and replaces the
capability bit with a reserved one.

Thanks to Justin Pettit for the history.

Brandon Heller b1e7cc00bc Spec: Add IP ToS rewrite action 
Enable additional basic QoS support, without requiring a full QoS
framework.  This commit defines a flow action to rewrite the DiffServ
CodePoint bits of the IP ToS field in the IP header.

Brandon Heller 25d7c2ecd2 Spec: Fix typo in diagram 
In the flow table matching picture, Ethernet type was compared to 0x8000
when 0x0800 was intended.

Brandon Heller 98ee054722 Spec: Minor change to CHECK_OVERLAP text 2009-06-29 11:37:28 -07:00
Brandon Heller 1a5762fbd2 Spec: Fix ambiguity regarding the duration field in Flow Expirations 
Before this spec change, flow expiration messages included a duration
field for the time the flow was active.  To find out the amount of time
the flow received traffic would have been much harder - the controller
would need to store a record of all flow mods it has sent, to know the
idle_timeout of this flow.  Additionally, both phrases, 'time flow was
active' and 'time traffic was received' were used in the spec for the
duration field.

Now we return the idle timeout in the flow expiration message, and ensure
duration is the time the entry was present in the flow table.  The hard
timeout will be obvious if it is the reason for the deletion, since the
reason field will be OFPER_HARD_TIMEOUT, and the duration will be the hard
timeout value.  From the duration and the idle_timeout, we can also
compute the time the flow received traffic.
 2009-06-29 11:37:28 -07:00
Brandon Heller 4f0da65910 Spec: Define behavior for conflicting flow mods 
Define a CHECK_OVERLAP flag for flow mods which requires the switch to
check for conflicting entries with the same priority, i.e., those for
which at least one packet could match multiple entries.

This flags is intended to be used for debugging purposes; in the worst
case, it may require a linear check through the flow table.
 2009-06-29 11:37:28 -07:00
Brandon Heller 91617a4690 Spec: Add VLAN priority bits 
The OpenFlow 10-tuple is now officially an 11-tuple, with the addition of
the VLAN priority (PCP) field.
 2009-06-29 11:37:28 -07:00
Brandon Heller 90bdc8626b Spec: Add barrier commands 
Add barrier request message, which ensures that all previously received
commands are complete before executing ones past the barrier message.  A
barrier reply must be sent for each barrier request.

We expect this command to be useful for testing and wireless handover
purposes.
 2009-06-29 11:37:28 -07:00
Brandon Heller f874420531 Spec: Start port enumeration at 1 
A number of protocols such as SNMP and STP start counting ports at one. To
increase compatibility, this commit adds a requirement that OpenFlow
ingress port values start at one.
 2009-06-29 11:37:28 -07:00
Brandon Heller e9353ae079 Spec: Add _EPERM error codes 
An OpenFlow hypervisor might choose to reject an OpenFlow request, but
currently has no message type defined for this error. It is not a
vendor-specific error, thus we define an _EPERM error code for each error
type.

Also remove unused, commented-out text.

VLAN tag if one is present. The header is the generic action header.

Brandon Heller 16e2b8ba6d Spec: Clarify transaction ID for error messages 
Note that if an error is in response to a specific message from the
controller, the transaction ID should match that from the original
request.

Brandon Heller 4b969c68f3 Spec: Clarify matching for disabled STP ports

the normal flow table processing path.
 2009-06-29 11:36:32 -07:00
Brandon Heller 3a7d98b612 Spec: Clarify matching behavior for flow mods and stats 
The spec does not currently define how wildcard matching should behave for
flow modification (specifically DELETE and MODIFY commands) and stats.
This commit adds text to define behavior when some fields are wildcarded
and others are left exact.

Brandon Heller 0c370a5ef9 Spec: Remove distinction between Type 0 and Type 1 
People tend to get confused about "Type 0" and "Type 1" vs "Version 1.0" and
"Version 2.0".  To simplify, we'll drop the reference to types.
 2009-06-29 11:36:32 -07:00
Brandon Heller b5525791b5 Spec: Notify controller of flows that are forcefully deleted 
Previously, a switch would only notify the controller when flows expired.
Now, when a switch is told to delete flows, it sends a flow expiration
message, enabling the controller to get packet and byte counts from
deleted flows. Without this, the controller must retrieve flow statistics
and then delete the flow, during which time the counts could change. This
could also aid in debugging if multiple applications or programs
controlling the same switch are deleting each others' flows.

This commit adds a OFPER_DELETE as a choice for the reason field of a flow
expiration.
 2009-06-29 07:07:29 -07:00
Brandon Heller a00b917457 Spec: Selective flow expirations 
Make flow expirations per-flow-entry, rather than per-switch.

This commit should give controllers extra flexibility to decide when they
want expirations, will simplify the job of an OpenFlow hypervisor, and may
reduce CPU load at the switch.
