QoS priority：Carry in the heading of message.Conventional QoS priority field includes 802.1p, differential service
Code point (Differentiated Services Code Point, DSCP), EXP (experimental) etc..User is permissible
According to the different QoS priority field used in heterogeneous networks of the network planning, such as in VLAN (Virtual
Local Area Network, VLAN) 802.1p used in network, in Internet protocol (English：Internet Protocol,
Referred to as：IP) DSCP used in network, in multiprotocol label switching (English：Multi-Protocol Label Switching,
Referred to as：MPLS) EXP used in network.
Local first level：It is a kind of priority with local significance, after message reaches forwarding unit, one can be allocated
Local data domain, this local data domain can be used for storing local first level.Local first level only has 0～7 eight values, right
Answer eight exit port queues of queue0～queue7.
With reference to Figure of description and each embodiment, technical scheme is illustrated.
Forwarding unit can be summarized as follows to the handling process of message：
First, the priority mapping on direction and other Business Processing are carried out to message；Secondly, routing table is searched；Again
Secondary, OpenFlow forward process is carried out to message；Then, the priority mapping on outgoing direction is carried out to message；Finally, reported
Text is joined the team column processing.
As the enforcement order of OpenFlow forward process is after the priority mapping on direction is entered, on outgoing direction
Before priority mapping, and OpenFlow forward process and priority mapping are required for using local first level, so at present
For equipment, cannot be while the use priority mapping function and OpenFlow forward process function.
For this purpose, present applicant proposes a kind of message processing method and device, by the built-in attribute QoS-local- of message
Id (the local identifier of service quality) is transmitting the queue ID of OpenFlow queue, so that OpenFlow queue function and excellent
First level mapping function can be used simultaneously.
The message processing method that the application is provided, can be applicable to the OpenFlow virtual net shown in Fig. 1, OpenFlow virtuality
Net includes OpenFlow controller (hereinafter referred to as controller) 100, forwarding unit 110 and escape way (Secure
Channel) 120, wherein, the escape way 120 between controller 100 and forwarding unit 110 by being pre-configured with communicates.
Controller 100, is the control centre of OpenFlow virtual net, for according to the configuration of user or dynamic operation
Protocol generation flow table is sent to forwarding unit 110.Flow table is the core data knot that forwarding unit 110 carries out forwarding strategy control
Structure, including matching domain (English：Match), enumerator (English：Counter) and action fields (English：Action).
Forwarding unit 110, for receiving the flow table that controller 100 is issued, and is processed to message according to flow table, such as
OpenFlow forward process, priority mapping etc..
Below by Fig. 2, the message processing method provided by the application is described.
Referring to the method flow diagram that Fig. 2, Fig. 2 are provided for the application.As shown in Fig. 2 the flow process may include following steps：
Step 201：Forwarding unit receives message by first port.
Step 202：Forwarding unit finds, in local having, the first flow table item that mates with first message in flow table item.
Step 203：Forwarding unit determines that the exit port that first flow table item is indicated is second port, according to described second
The value of the QoS-local-id of first message is set to the qos policy that port enables the team of first flow table item instruction
The value of row ID, first message is added in the exit port queue that is mated with the Qos-local-id of first message.
Wherein, the local flow table item of forwarding unit is handed down to forwarding unit in advance by controller, and flow table item is generally comprised
Matching domain and action fields.
Matching domain is used for matching message, can be the five-tuple of message, the type of message (as video traffic message, voice
Service message) etc..
In the application, the action fields of flow table item are used for indicating when message is mated with matching domain by the QoS- of the matching message
The value of local-id is set to the value of specified queue ID and the matching message is forwarded to specified exit port, for example, it is possible to refer to
Show and matching message is forwarded to specific exit port R2, and the Qos-local-id of the matching message is entered as 1.So report
Text is most sent from the queue that the queue ID of exit port R2 is 1 at last.
In the application, same equipment sends and is sent to the different messages of same purpose equipment, through forwarding unit
When, can send from the different queue of forwarding unit same port.Specific implementation is as follows：
Forwarding unit receives the second message by first port, and the second message is different from the first message in step 201.
For example, if the five-tuple of the first message is different from the second message, e.g., the source port of the first message is different from second
The source port of message, then it is considered that the second message is different from the first message.Again for example, if the type of the first message is different from
The type of the second message, such as the first message are video traffic messages, and the second message is speech business message, then it is also assumed that
Second message is different from the first message.
After forwarding unit receives the second message, find, in local having, the second for mating with the second message in flow table item
List item.
Then, forwarding unit determines that the exit port that the second flow table item is indicated is second port, enables according to second port
The value of the QoS-local-id of the second message is set to qos policy the value of the queue ID of the second flow table item instruction, and second is reported
Text is added in the exit port queue that is mated with the Qos-local-id of second message.
Wherein, the value for arranging if the QoS-local-id of the first message is different from the QoS-local- for the second message
The value that id is arranged, then although the first message and the second message are all forwarded to second port, but the first message and the second message
Different exit port queues are entered, and is forwarded from different exit port queues.
Different queues can correspond to different Flow Behaviors, and Flow Behavior is the QoS action that is done for message, including true
Protect and forward (Assured Forwarding, AF), fast-forwarding (Expedited Forwarding, EF), Weighted Fair Queuing
(Weighted Fair Queuing, WFQ) etc..
As the application transmits the queue ID of OpenFlow queue by the built-in attribute QoS-local-id of message, no
Queue ID is carried using the local first level to message, so as to priority mapping function or other use local first level
Function all can with OpenFlow forward process function and meanwhile use.
By taking priority mapping function as an example, before the flow table item that mates with message is found, forwarding unit can be according to pre-
If the priority mapping relation for entering on direction, the initial Q oS priority mapping that the message is carried is local first level；And
After finding the flow table item that mates with message, according to the priority mapping relation on default outgoing direction, by the local of the message
Priority mapping is new QoS priority, and the initial Q oS priority that the message is carried replaces with the new QoS priority.
Before and after mapping, the value of QoS priority or type are likely to occur change.
For example, when the value for needing the priority for lifting some messages according to actual networking requirements, excellent to reach these messages
During the purpose being first processed, the mapping relations of the different priorities value of same priority field can be configured on forwarding unit.
Such as, on direction is entered, configuration preference level is mapped as DSCP-LP (60-6), and on outgoing direction, configuration preference level is mapped as
LP-DSCP (6-63), then after the message that certain initial DSCP is 60 enters forwarding unit, in the side of entering upwardly through priority
It is 6 that mapping can arrange the LP of the message, and the value of the DSCP that the message can be carried by priority mapping in outgoing direction is set
It is set to 63.
Again for example, when message is through heterogeneous networks, in order to keep the priority of message, can be in connection heterogeneous networks
The mapping relations of different priorities field are configured on forwarding unit.
Such as, on direction is entered, configuration preference level is mapped as DSCP-LP (60-6), and on outgoing direction, configuration preference level is mapped as
LP-EXP (6-50), then after the message that certain initial DSCP is 60 enters forwarding unit, in the side of entering upwardly through priority
It is 6 that mapping can arrange the LP of the message, the precedence field of the message can be changed by priority mapping in outgoing direction
For EXP.
Further, since the span of the built-in attribute QoS-local-id of message be 1 to 4095, so if by
Join QoS-local-id and message is sent into different queues, then the model of the number of queues that each port of forwarding unit can be arranged
Enclose for 1 to 4095, i.e., 4095 queues can be at most set in each exit port, it is clear that the usable range of queue is improve, can
To meet the application scenarios of a large amount of queues.
In order to be illustrated more clearly that the technical scheme of the application, below by one embodiment technique scheme is done into
The explanation of one step, it should be noted that this embodiment is only a kind of implementation of the application, does not constitute the limit to the application

Show, when the QoS-local-id of message is 1, message is sent into queue 1；When the QoS-local-id of message is 2, by message
Send into queue 2；When the QoS-local-id of message is 3, message is sent into queue 3；When the QoS-local-id of message is 4
When, message is sent into queue 4.
3rd, device A is sent to the R1 mouth entrance of 4 message flows of equipment B from forwarding unit.Forwarding unit is by message flow and control
Device processed is set in advance in local flow table item and is mated one by one, and the flow table item according to coupling carries out action queue sets to message
(Set-Queue).For example, the QoS-local-id of message flow 1 is entered as 1, the QoS-local-id of message flow 2 is entered as
2, the QoS-local-id of message flow 3 is entered as 3, the QoS-local-id domain of message flow 4 is entered as 4, then this 4
Message streams to R2 mouth.
4th, this 4 message flows mate the QoS-local-id value of itself on R2 mouth and enter different queues.As Fig. 5 institute
Show, QoS-local-id (1) corresponding queue 1, QoS-local-id (2) corresponding queue 2, QoS-local-id (3) correspond to queue
3, QoS-local-id (4) corresponding queues 4.Finally, message flow 1 is sent from the queue 1 of R2 mouth, and message flow 2 is from the queue 2 of R2 mouth
