Specific embodiment
For the ease of the understanding of those skilled in the art, the invention will be further described with reference to the accompanying drawing, not
It can be used to limit the scope of the invention.It should be noted that in the absence of conflict, embodiment and reality in the application
The various modes applied in example can be combined with each other.
Data transmission method provided in an embodiment of the present invention is for introducing this in the data transmission based on FLEXE agreement
Before data transmission method and device that inventive embodiments provide, the related content in FLEXE agreement is introduced first.
FLEXE agreement is defined according to physical layer 100G rate at present.In optical mode is fast, the data message of 100G is being sent
Before, it is that data packet messages are carried out to 64/66 coding, the data block of 64 bits is extended to the block of information of 66 bits, increased 2 ratio
Spy is located at before 66 bit blocks, as the opening flag of 66 bit blocks, is then sent in a manner of 66 bit blocks from optical port.
When receiving, optical port identifies 66 bit blocks from the data flow received, and original 64 are then recovered from 66 bit blocks
Bit data re-assemblies data message.
FLEXE agreement is in after 64 bits to 66 pieces of conversion layers, before sending 66 bit data blocks, to the number of 66 bits
It is ranked up and plans according to block, such as Fig. 3 A: for 100G business, every 20 66 bit data blocks are divided into a data chunk,
Totally 20 data blocks in every group, represent 20 time slots, and each time slot represents the business speed of 5G bandwidth, 20 time slots compositions
The time slot calendar of FLEXE.When the physical layer of 4 road 100G is bundled into the logic business bandwidth of a 400G, structure of time slot
It is made of 80 (4*20) a time slots, Calendar is 80 time slots, is divided into 4 groups, every group of 20 time slots, every group is a member
subcalendar.In physical layer, each physical layer carries the content of a member (subcalendar), still according to 20 data
Block forms a data chunk, and every 1023 data chunks are inserted into an expense block.Expense block plays positioning action, multiple members
It is positioned and is sorted on the basis of expense block, to restore business.It is every to have sent 1023 numbers when sending the data block of 66 bits
According to block group (1023*20 data block), it is inserted into a FLEXE expense block, such as black block in Fig. 3 A.After being inserted into expense block, continue
It sends data block and is inserted into expense block after having sent second 1023*20 data block, and so on, sending data in this way
During block, it can be periodically inserted expense block, the interval of two neighboring expense block is 1023*20 data block.It is receiving
End, each physical layer detection receive data, determine each 66 block information blocks, identify FLEXE expense block (block of information of black)
Afterwards, so that it may determine 20 time slot blocks.When logical channel is bundled by multiple physical managements, such as Fig. 3 C, each physics is logical
Road positions FLEXE expense respectively, determines respective 20 time slots, logical according to each physics then using expense block as alignment mark
This member number carried in expense block in road determines that the Queue sequence between member (is arranged from small to large according to member's number
Sequence), the time slot of all members is formed into a big time slot group calendar, then recovers client traffic.
FLEXE expense block is the expense block of 66 bit longs, when business data flow is sent, at interval of 1023*20
Data block is inserted into an expense block.Expense block plays positioning function in entire Business Stream, finds expense block, so that it may know industry
The position of first data chunk and the position of subsequent data chunk in business.The content of expense block such as Fig. 3 D, continuous 8
Expense block then forms an expense frame.One expense block is made of the block content of the block mark of 2 bits and 64.Block mark is located at
Preceding 2 column, behind 64 column be block content, the block mark of first expense block is 10, behind the block marks of 7 expense blocks be 01 or SS
(SS indicates that content is uncertain).The content of first expense block is: (1, indicate for 0x4B (8, hexadecimal 4B), C bit
Adjustment control), OMF bit (1, indicate expense frame multi-frame instruction), RPF bit (1, indicate remote bug instruction), RES ratio
Special (1, reserved bit), FLEXE group number (20, indicate the number of binding group), 0x5 (4, it is hexadecimal
5), 000000 (0) 28, be all.0x4B and 0x5 therein are the mark instructions of first expense block, when receiving, when finding
Corresponding position is 0x4B and 0x5 in one expense block, then it represents that after the expense block is first expense block in expense frame and is secondary
Continuous 7 expense blocks form an expense frame.In expense frame, the part reserved is to retain content, not yet defines, sees figure
3B black block.Fig. 3 E is FLEXE protocol overhead multi-frame structure schematic diagram.Other byte contents are not closed with the application in expense frame
System, no longer illustrates.
Define 8 expense blocks in FLEXE agreement and form a frames, such as Fig. 3 D, wherein in first expense block by 4B (16 into
System, is identified as 0x4B) and 05 (16 systems, be identified as 0x5), two field identifications.In expense block, detect that corresponding position is
4B and when 05 content, then it represents that the expense block is that first expense block and subsequent 7 expense blocks form a frame.
In FLEXE expense frame structure, FLEXE group number indicates FLEXE binding group mark, all group
The identical member of number belongs to one group.PHY number is member's number, in the same group number, Mei Gecheng
The PHY number of member is that uniquely, all members are to carry out according to the ordering rule of PHY number from small to large in sequence
Sequence.PHY number is 8 data, can indicate all numbers between 0-255, therefore in a group be up to
256 members.It is to retain number that 0 and 255 are defined in Current standards, and special applications, normal member use the volume of 1-254 altogether
Number.
In first expense block, OMF field is multi-frame indication signal, such as Fig. 3 D.OMF is single-bit numerical value, continuous 16
It is 0 in frame, is then 1 in continuous 16 frame, being then again is 0 in continuous 16 frame, is then 1 in continuous 16 frame, every 32 frame repeats
Once, such multi-frame is exactly to be made of 32 frames.In frame, Client calendar field indicates the configuration information of each time slot,
It can indicate that this time slot belongs to that client by Client calendar with business in carrying.Client traffic is needed in carrying
The number of timeslots wanted is uncertain, it would be desirable to be able to flexibly modification, therefore Client calendar has two sets of configuration informations,
Client calendar A and Client calendar B, two sets of Configuration Values are worked respectively in operating mode and standby mode,
For dynamic, smoothly handover configurations information.A time point, only a set of Configuration Values are in operating mode, another
Configuration Values are in standby mode.When needing to modify Configuration Values, then the Configuration Values of standby mode are modified, while opposite end being notified to indicate this
The Configuration Values of port are changed, and opposite end is prepared according to new Configuration Values, are passed back to originating end after being ready to, and wait both ends
After consensus, start the switching flow of allocation list, then becomes standby mode in operating mode allocation list originally, will locate originally
Repairing in standby mode allocation list becomes operating mode, realizes the dynamic adjustment of configuration information.
Multiple physical channels are bundled into a logical channel by FLEXE agreement, solve the wide demand of big business transfer tape.
Since FLEXE agreement is that multiple physical channels are bundled into the logical channel of business transmitting, when a physical channel occurs
When failure, then entire logical channel breaks down, and the reliability of logical channel reduces, and the probability that logical channel breaks down increases
Add several times, multiple is exactly the total quantity of physical channel.In FLEXE agreement current version, when event occurs for a physical channel
When barrier, needing the method for carrying out business recovery can only eliminate the channel member to break down from group, increase again
Add a newcomer.This is related to operating as follows and step: (1), transmitting terminal: sending and delete client traffic from failure member
Notice, failure member do not transmit client traffic；(2), receiving end: approve the time slot configuration amendment advice of transmitting terminal, provide reception
It replies；(3), transmitting terminal: client traffic is deleted from failure member, failure member does not transmit client traffic；(4), receiving end:
No longer client traffic is received from failure member；(5), increase newcomer, customer information is received from newcomer.Current this solution
Certainly method, there are drawbacks: (1), when a member breaks down, such as when transmitting-receiving optical fiber is dug disconnected simultaneously, the member is two
Information can not be normally transmitted between platform equipment, fault message is that one direction is known, each party, which only knows, oneself here to be connect
Time receiving failure, but do not know that whether other side receives normal, can not determine unidirectional fault or bi-directional failure, can not start deletion
The work of client slot；(2), when a member breaks down, sending and receiving end can not normally transmit information, can not
The notice and confirmation work for carrying out time slot deletion, not can be carried out the activity for deleting faulty channel time slot；(3) logical even if deleting failure
A series of activities such as the activity of road time slot can carry out, and entire deletion activity needs to shake hands by negotiation, have been more than communication network
Seeking time is wanted to service disconnection.In communication system, when communication channel breaks down, needing can be fast to key client's business
Speed is protected and is restored, and business interruption time is no more than 50ms.
In application based on FLEXE agreement, the embodiment of the present invention provides a kind of data transmission method and device, to client's industry
Business is classified: Very Important Person and normal client.The service quality of Very Important Person is very high, can be quickly extensive when service disconnection
Restitution business, break period are no more than 50ms；Normal client provides general service quality, does not guarantee recovery time after service disconnection,
Recovery time is longer (for example, could restore after waiting failure vanishes) after service disconnection.Such as Fig. 4 A, member (No. 1,2 of 5 100G
Number, No. 3, No. 4, No. 5 members, wherein 1-4 member is service aisle, and No. 5 members are protection channels) one FLEXE of composition
Group, total transmission bandwidth are 500G.Two clients are carried on group, one is Very Important Person, the bandwidth of 400G；One is
Normal client, the bandwidth of 100G.In configuration, by the Very Important Person business configuration of 400G on 1,2,3, No. 4 member, by 100G
Normal client configure on No. 5 members.When FLEXE bearer path is all normal, Very Important Person and normal client all obtain can
By transmitting.As shown in Figure 4 B, when member 1 is broken down, the identity of member 1 is quickly turned to member 5, while the identity of member 5
Be quickly turned to member 1, transmit Very Important Person instead of original member 1, the number of such 5 members by 1,2,3,4,5, become 5,
2,3,4,1, Very Important Person just still is transmitted by 1,2,3,4 members in group, No. 5 members transmit normal client, and Very Important Person exists
Quick-recovery it can get up fastly after instantaneous interruption, business interruption time is very short.Normal client is carried by the member interrupted, commonly
Client is broken down, and could restore normal after waiting failure vanishes.The member that breaks down is replaced by spare physical channel, it can be with
The impaired Very Important Person business of fast quick-recovery, has ensured the service quality of Very Important Person.This service protecting method, only works
Ability starting protection activity when channel is broken down sacrifices normal client and ensures Very Important Person.It is general when member is there is no when failure
Logical client and Very Important Person are all normally transmitted, and business is unaffected.
Referring to Fig. 6, the invention proposes a kind of data transmission methods, which comprises
Step 200, pass through logical channel transmission services data；Wherein, the number of first kind business is transmitted by working member
According to；The data of the second class business are transmitted by protection member；Wherein, the priority of first kind business is higher than the second class business；
Each physical channel in logical channel is divided into working member or protection member, and each physical channel is corresponded respectively in each work
Make member or respectively protects member；
Step 300, when working member meets preset switching condition, by the corresponding physical channel of the working member with
The corresponding physical channel of protection member is interchangeable.
In the embodiment of the present invention, first kind business is important client traffic；Second class business be normal client business, first
Class business is relatively high for the requirement restored after interrupting, therefore the object as priority protection.
Referring to Fig. 5, after step 200 further include:
Step 400, in receiving end, volume of each member in each FLEXE expense frame in each physical channel is detected
Number situation sorts according to member's number order, restores all time slots and client traffic.
It is appreciated that step 300 and step 400 are without specific sequencing.
In the embodiment of the present invention, it includes such as one of under type that the working member, which meets preset switching condition:
The working member is broken down corresponding physical channel；
Working member's bearer path situation is detected, meets protection operational requirements in working member's bearer path situation
When, working member's bearer path situation includes that channel interrupt, error code are at least one of out-of-limit.
In the embodiment of the present invention, before step 200 is by logical channel transmission services data, the method is also wrapped
It includes:
Step 100, working member and corresponding physical channel are determined, determines protection member and corresponding physical channel.
In step 100, protected mode can be 1 multiple working member of protection member protection, and (N is positive whole by such as 1:1,1:N
Number)；Protected mode can be the multiple working members of multiple protection member protections, and such as 2:N, 3:N etc., N is positive integer.
For example, including 5 physical channels in logical channel, it can be set are as follows: 4 physical channels are that working member is corresponding
Physical channel, 1 physical channel are the corresponding physical channel of protection member；May be set to be: 3 physical channels be work at
The corresponding physical channel of member, 2 physical channels are the corresponding physical channel of protection member.
Step 100 further include: determine the PHY number of working member and the PHY number of protection member, protect member
PHY number can be particular values, such as maximum value, the minimum in all members, or be 0 so as to receiving end differentiation, or
It is 255 etc..
Under normal circumstances, working member transmits business in its corresponding physical channel, protects member in its corresponding object
It manages channel and transmits business.
When sending business datum, working member and protection member can be used for carrying different data, for example, working
The business datum that Very Important Person is carried on the time slot of member, carries the business datum of normal client on the time slot of protection member.
In the embodiment of the present invention, the number of physical channel is R in logical channel；
The determining working member and corresponding physical channel, determine protection member and corresponding physical channel includes: to set
The number for setting working member is M, and the number of setting protection member is N；M+N=R；M, N, R are positive integer.
In step 200, need to be described as follows several points:
2-1, under 1:N mode, the selector type on working member and corresponding physical channel is 2 to select 1, selector one
A input carrys out self-shield member from working member, an input；Selector type on spare member and corresponding physical channel
It is that N+1 selects 1, N number of input comes from working member, and an input carrys out self-shield member.
2-2, under 2:N mode, the selector type on working member and corresponding physical channel is 3 to select 1, selector one
A input carrys out self-shield member from working member, two inputs；Selector type on spare member and corresponding physical channel
It is that N+1 selects 1, N number of input comes from working member, and an input carrys out self-shield member.
Selector selection working member is defeated on 2-3, in normal operating conditions, working member and corresponding physical channel
