ISP's (English：Internet service provider, referred to as：ISP fortune)
In battalion's business's network, Provider Edge (English：Provider edge, referred to as：PE) equipment would generally be right
The data traffic sent by the user of the PE equipment access operator networks carries out traffic policing.
As shown in figure 1, user 1 and user 2 are by the access network 2 of the network equipment 105, the network equipment
105 according to user 1 and user 2 each bandwidth set in advance to user 1 and user 2 to the network equipment
105 data traffics for sending are supervised.
When mutually sending data between two networks of different operators, a PE for carrier network
The flow of the data that equipment can also send to another carrier network to the PE equipment is supervised.
For example, the network equipment 102 in network 1 shown in Fig. 1 sends to the network equipment 103 in network 2
Data.The network equipment 102 presets bandwidth to net to the network equipment 103 to the transmission data of network 1
The data traffic that network equipment 103 sends carries out traffic policing, and the network equipment 103 is also to the network equipment 102
The bandwidth that presets for sending data to network 2 is supervised to the data traffic that the network equipment 102 sends
Pipe.
For example, the network equipment 101, can to the network equipment 105, user 1 and user 2
Be router, the network switch, fire wall, WDM, Packet Transport Network equipment, base station,
Base station controller or data center etc..
For sake of convenience, in the application, the equipment of data, referred to as institute will be sent by certain network equipment
State the user of certain network equipment.For example, the user mentioned in the application, both can be shown in Fig. 1
Being set to network shown in the user 1 and user 2, or Fig. 1 of data is sent to the network equipment 105
Standby 103 network equipments 102 for sending data.
The network equipment presets bandwidth to each user.For example, the bandwidth can be by the grade of service
Agreement (English：Service-level agreement, referred to as：SLA) set, it is also possible to by stream
Amount adjustment agreement (English：Traffic conditioning agreement, referred to as：TCA) set.
When the data traffic that user is sent to the network equipment is more than bandwidth set in advance, the network equipment
Forwarding will be abandoned or postponed beyond the data for presetting bandwidth.
Under normal circumstances, the network equipment to the oversight mechanism of flow generally by token bucket algorithm to being sent to
State the network equipment message whether in the network equipment to being carried out within such message bandwidth set in advance
Mark, and further determined whether that message is carried out the treatment such as to forward according to mark.For example, being noted in request
Solution (English：Request for Comments, RFC) 2697 define single-rate three-color marker (English
Text：Single Rate Three Color Marker, referred to as：SrTCM), it is fixed in RFC2698 standards
Justice a two rate three color marker (English：Two Rate Three Color Marker, referred to as：trTCM).
The network equipment can use committed access rate (English to bandwidth set in advance described in message：
Committed access rate, referred to as：CAR) describe.For example, in trTCM, net
Network equipment can be by committed information rate (English to each user bandwidth set in advance：committed
Information rate, referred to as：CIR) and peak information rate (English：Peak information rate,
Referred to as：PIR) describe.CIR refers to the bandwidth that network equipment promissory warranty user transmits data, PIR
It refer to the network equipment when user's transmitted data amount is larger, it is allowed to the bandwidth that user can additionally use.Net
Network equipment ensures user can be forwarded with being not more than the data of CIR transmission by the network equipment.In net
Network equipment ensure that after the business that each user is transmitted within the CIR, if the network equipment also have it is surplus
Remaining bandwidth, the then data that can forward user to be transmitted more than CIR and less than or equal to PIR；The network equipment
Abandon or postpone data of the forwarding user to be transmitted more than PIR.
Accordingly, the token bucket of trTCM includes C barrels and P barrels.Increased with CIR in described C barrels and made
Board, it is described P barrels in token is increased with PIR, until the token quantity in corresponding bucket reaches and presets
The upper limit.For example, the upper limit set in advance is by Committed Burst Size (English in described C barrels：Committed
Burst Size, referred to as：CBS) describe, it is described P barrels in the upper limit set in advance happened suddenly by peak value
Size (English：Peak Burst Size, referred to as：PBS) describe.
Each token represents a data traffic for unit, the i.e. network equipment in the message that the network equipment is received
A data for unit are often forwarded, then 1 token is deducted from corresponding token bucket.For example, an order
Board can represent a bit (English：Bit), a byte (English：) or eight hytes Byte
(English：octet).Token bucket increases token with certain speed, refers to increase in token bucket in the unit interval
Plus token quantity corresponding to data volume, it is equal with the speed.Such as CIR is 100Mbit/s,
Token is added with CIR, 1 token represents 1bit, refers to increase 1M tokens per second.
Below by taking trTCM as an example, the method to being realized traffic policing by CAR is described in detail.
Fig. 2 is shown a kind of network equipment and the method flow that data traffic is supervised is realized using trTCM
Figure.After the network equipment receives message, the corresponding token bucket of the message is determined, the token bucket includes
P barrels and C barrels.Then, the network equipment performs following steps.
S201, the network equipment determines the token quantity in P barrels.If the token quantity in described P barrels is small
In 0, S202 is performed, if token quantity is more than 0 in described P barrels, perform S203.
The packet labeling is red by S202, the network equipment.Specifically, labeled as red,
Mean that the corresponding user's current data flow of the token bucket has exceeded PIR.Further, network sets
It is standby to abandon or postpone to send the message.
S203, the network equipment determine it is described C barrels in token quantity.If in described C barrels
Token quantity is less than 0, performs S204.If the token quantity in described C barrels is more than 0, S205 is performed.
The packet labeling is yellow by S204, the network equipment, is deducted accordingly from described P barrel
Token number.Specifically, labeled as yellow, it is meant that the corresponding user's current data stream of the token bucket
Amount is not above PIR more than CIR.Further, whether the network equipment detection currently has
Remaining bandwidth.If the network equipment currently has remaining bandwidth, the message is forwarded.If described
The network equipment then abandons or postpones to send the message currently without remaining bandwidth.Additionally, the network
Equipment also deducts corresponding token number from P barrels.For example, the size of the message is 640bit, each
Token represents 1bit, then 640 tokens are deducted from described P barrels.
The packet labeling is green by S205, the network equipment, from described P barrels and described C barrels
It is middle to deduct corresponding token number respectively.Specifically, labeled as green, it is meant that the token bucket correspondence
User's current data flow be less than or equal to CIR.Further, the network equipment forwards the message.
It is green by packet labeling, refers to that corresponding with the message first is set in the network equipment
Mark, described first identifies for indicating the network equipment to the forwarding of the message in the message pair
Within the CIR for answering, the network equipment should forward the message.It is red by packet labeling, refers to
The second mark corresponding with the message is set in the network equipment, and described second identifies for indicating
Forwarding of the network equipment to the message sets beyond the corresponding CIR of the message, and the network
It is standby to abandon or postpone the forwarding message.It is yellow by the packet labeling, refers in the network
The 3rd mark corresponding with the message is set in equipment, and the described 3rd identifies for indicating the network to set
The standby forwarding to the message is beyond the corresponding CIR of the message, but the network equipment is to described
Message forwarding, discarding postpone forwarding, depending on the bandwidth of the network equipment current residual.
For example, the network equipment 105 shown in Fig. 1 can be using above-mentioned token bucket respectively to user 1
The data traffic sent with user 2 is supervised, and the network equipment 103 shown in Fig. 1 can use above-mentioned
Token bucket is supervised to the data traffic that the network equipment 102 sends.
However, same user is for different all types of business, it is understood that there may be different bandwidth demands.
That is, when the user is sent to the total data flow of the network equipment beyond bandwidth set in advance,
User needs the network equipment to ensure that priority business high is forwarded first, or needs the network equipment to ensure
The ratio that the business of high priority is forwarded is not less than ratio set in advance.
For example, user sends service message and operational administrative within a period of time to the network equipment
Safeguard (English：Operations, administration and maintenance, referred to as：OAM) report
The total flow of text, the service message and OAM message is more than CIR.And OAM message exists for user
Communication plays an important roll in network, and flow occupancy is smaller, therefore user needs always to be flowed in data
When amount is more than CIR, the preferential forwarding for ensureing OAM message.In scheme shown in Fig. 2, if
The service message for first reaching the network equipment uses up the token in the corresponding token bucket of the user, then described
Before token bucket not yet adds enough tokens, the OAM message reaches the network equipment, then may be used
Can be abandoned by the network equipment.Actual demand with user is not inconsistent.
Fig. 3 shows a kind of flow of data traffic monitoring and managing method provided in an embodiment of the present invention.
S301, the network equipment receives message.
For example, the network equipment can be the network equipment 101 shown in Fig. 1 to the network equipment 105
In a network equipment.
S302, the network equipment determines corresponding first token bucket of the message.
For example, first token bucket is the token supervised for the total flow to first user
Bucket, the message is the message that the first user sends to the network equipment.Possible show in one kind
In example, the network equipment determines the first user by receiving the port of the message.In another kind
In possible example, the network equipment determines the first user by the field in the message.
For example, the field can be VLAN (mark (English：virtual local area network
Identifier, referred to as：VID) field.The network equipment is by inquiring about VID set in advance and user
Mapping, determine the first user.
Optionally, the network equipment obtains field according to instruction set in advance from the message.Such as
The value of really described field is preset value, and the network equipment creates the corresponding priority symbol of the message.
For example, specify in SLA of the network equipment with the first user, described first
Total number of users exceedes when presetting bandwidth of the first user according to flow, and OAM message is ensured first
Forwarding.The message that the network equipment is received is ethernet frame (English：Ethernet frame),
The network equipment is from the ethernet frame stem (English in the message：Header too net class is extracted in)
Type (English：EtherType) field, for 0x8902, (16 enter the value of the EtherType fields
System), i.e., described message is OAM message, then the network equipment establishment message is corresponding preferential
Mark.
For example, the network equipment sets the message corresponding metadata (English by instructing：
Metadata in), the priority symbol is write in the metadata.For example, the message pair
In the metadata for answering, with the priority symbol, the priority symbol is 0, it is meant that described
Message does not exist corresponding priority symbol.The network equipment is set to 1 by by the priority symbol,
Create the priority symbol.
For example, if defining CIR in SLA between the network equipment and the first user
And PIR, then first token bucket can be the token bucket including C barrels He P barrels shown in Fig. 2.Such as
CIR is specify only in SLA between the really described network equipment and the first user, then first order
Board bucket can also be the token bucket of srTCM specified in RFC2697.First token bucket can be with
C barrels shown in Fig. 2 is only included, i.e., when having available token in C barrels, the network equipment is by C
Labeled as green, when not having available token in described C barrels, the network equipment marks C barrels to bucket
It is red.
S303, the network equipment determines whether there is priority symbol corresponding with the message.If deposited
In priority symbol corresponding with the message, S304 is performed；If there is no corresponding with the message excellent
First identify, perform S305.
For example, the priority symbol can be the priority symbol of establishment in S302.The network sets
It is standby that it is marked to the message in the token quantity by the message in first token bucket
Before, the corresponding metadata of the message is first read, whether include in the retrieval metadata described
Priority symbol.For example, the metadata includes priority symbol, value of the priority symbol etc.
In 1, it is meant that the message has corresponding priority symbol；The value of the priority symbol is equal to 0, meaning
Taste the message in the absence of corresponding priority symbol.
S304, the network equipment is deducted and the message data amount equal numbers from first token bucket
The token of amount, and be green by the packet labeling.
It should be noted that being deducted from first token bucket and the message data amount equal amount
Token, it, according to the corresponding token bucket algorithm of first token bucket, is being green by the packet labeling to refer to
Corresponding token is deducted respectively from some sub- token bucket in first token bucket during color.For example,
First token bucket includes as shown in Figure 2 C barrels and P barrels of the two sub- token bucket, then according to Fig. 2
Shown token bucket algorithm, the network equipment is deducted and the report from described C barrels and in described P barrels
The token of literary data volume equal amount.
In a kind of possible example, no matter the available token quantity in first token bucket more than etc.
In 0,0 is also less than, the network equipment is deducted and the message data from first token bucket
Measure the token of equal amount.I.e. for exist correspondence priority symbol message, no matter the current data of user
Flow exceedes how much preset bandwidth, and the network equipment ensures the message that there is the priority symbol
It is forwarded.
In alternatively possible example, the network equipment sets the first preset value, described first
Preset value is less than 0.If available token bucket quantity is more than or equal to institute in first token bucket
When stating the first preset value, the network equipment is deducted and the message data amount from the first token bucket
The token of equal amount；If the first token bucket quantity is less than first preset value, i.e. institute
The quantity of token in the first token bucket is stated for negative, and the absolute value of the negative presets less than first
The absolute value of value, it is meant that the network equipment is carried preferentially due to ensureing in the message that the user sends
The flow of the message of mark, forwarded quite in the case where bandwidth is preset beyond the user
The message of quantity, therefore the network equipment cannot again forward message of the user with priority symbol.
For example, first preset value is -2Mbit.
S305, the network equipment marks the message according to the quantity of token in first token bucket
Color.
It should be noted that in embodiment shown in Fig. 3, to realize the function of traffic policing, described
One token bucket needs at least can be by packet labeling into green or red both colors.First token
Whether bucket can be yellow by the packet labeling, or labeled as more other colors, the application does not do
Limitation.
Fig. 4 shows a kind of flow of data traffic monitoring and managing method provided in an embodiment of the present invention.
S401, the network equipment receives message.
S402, the network equipment determines corresponding second token bucket of the message.
S403, the face of network equipment message according to the number tag of token in the second token bucket
Color.If the message of token number tag of the network equipment in second token bucket
Color is green, performs S404 and its subsequent step；If the network equipment is according to the described second order
The color of the message of the token number tag in board bucket is not green, performs S405 and its follow-up step
Suddenly.
S404, the network equipment creates the corresponding priority symbol of the message.
S405, the network equipment determines corresponding first token bucket of the message.
S406, the network equipment determines whether there is priority symbol corresponding with the message.If deposited
In priority symbol corresponding with the message, S407 is performed；If there is no corresponding with the message excellent
First identify, perform S408.
S407, the network equipment is deducted and the message data amount equal amount from the first token bucket
Token, and be green by the packet labeling.
S408, the network equipment marks the message according to the quantity of token in first token bucket
Color.
For example, the message that the network equipment is received is the message of first user.The first user
SLA in specify first user CIR be 100Mbit/s, PIR is 120Mbit/s.Wherein, it is described
First user needs video traffic to ensure 30Mbit/s.Specifically, the first user needs video industry
Business ensures that 30Mbit/s refers to, if the video traffic flow is less than or equal to 30Mbit/s, total data
Flow is more than 100Mbit/s, then the video traffic needs complete in the corresponding token bucket of the first user
Portion is labeled as green；If the video traffic flow be more than 30Mbit/s, in the video traffic
Part within 30Mbit/s needs all to be marked in the corresponding token bucket of the first user,
Beyond the part of 30Mbit/s the remaining 70Mbit/s of CIR are shared with other business of the first user.
The second token bucket in S402 includes C barrels that adds token with the speed of 30Mbit/s.If institute
The message that message is video traffic is stated, then the network equipment determines the message correspondence second token
Bucket.For example, after the network equipment receives the message, the VID field of the message is obtained,
The VID field identifies the first user simultaneously and the message is video traffic.For example, institute
State VID field to be represented by 3 hexadecimal numbers, highest order is used to identify user, when highest order is 1,
Represent that the user is first user；Lowest order is used for mark business-type, when lowest order is 1, table
Show that the type of service is video traffic.When the value of the VID field is 0x101, the network sets
It is standby to determine that the message is the video traffic message of first user, so that it is determined that message correspondence described the
Two token buckets.
In a kind of possible example, second token bucket only includes described C barrels.In S403,
The network equipment judge it is described C barrels in whether include available token, if there is available token,
It is then green by the packet labeling；Then it is red by the packet labeling if there is no available token
Color.
In alternatively possible example, second token bucket include it is described C barrels, and with 30Mbit/s
Speed addition P barrels of token.In S403, flow mark of the network equipment according to Fig. 2
Remember the color of the message.
Can refer to such as RFC2698 it should be noted that there is available token in the application, in token bucket
In the trTCM of offer similar token bucket algorithm, the corresponding data volume of the quantity of token in the token bucket
More than the data volume carried in the message；May also mean that the token bucket being similar in flow as described in Figure 2
In algorithm, the corresponding data volume of the quantity of token is more than 0 in the token bucket.
For example, the network equipment described in S404 is by instructing the setting message corresponding
In metadata, the priority symbol is write in the metadata.
For example, corresponding first token bucket of the message is determined in S405, is the first user pair
The token bucket answered.For example, the token bucket includes C barrels and P barrels, described C barrels with 100Mbit/s's
Speed adds token, and the described P barrels speed with 120Mbit/s adds token.
The concrete mode of S406 to S408, the specific implementation with S303 to S305 is identical, no
Repeat again.
Fig. 5 shows a kind of schematic diagram of data traffic maintenance device provided in an embodiment of the present invention.
As shown in figure 5, data traffic maintenance device 500 includes receiving unit 501, the first determining unit
502, the indexing unit 504 of judging unit 503 and first.
The receiving unit 501 is used to receive message；
