Description
Technical field
The present invention relates to the events in the communications field more particularly to a kind of flexible Ethernet (Flexi1e Ethernet, FlexE)
Barrier notice and acquisition methods, device, communication equipment.
Background technique
In the past decade, network service traffic is always maintained at rapid growth, promotes the service bandwidth of communication apparatus quick
Increase, the interface rate of communication apparatus is increased to 100M from 10M bandwidth, then improves 1G, 10G, and every few years business speed is just turned over
Several times, to adapt to the demand of service traffics on network.The speed of the optical module of communication apparatus commercialization at present has reached 100G, and opens
Begin a large amount of commercial.When optical module speed starts to surmount 100G, difficult increasing, the optical mode that is encountered on optical module research and development technology
The production cost of block sharply increases.In developing from 100G to 400G, although having developed the optical module of 400G at present,
The optical module of 400G it is expensive, have been over the price of 4 100G optical modules, cause 400G optical module to lack commercial
Economic value.In the case where not increasing cost, in order to solve the transmitting demand of 400G business, can be transmitted on 100G optical module
400G business, International Standards Organization define FlexE agreement.FlexE agreement ties up the optical module of multiple 100G, is formed
The transmission channels of one big business speed pass through FlexE as shown in Figure 1, the figure show the universal architecture schematic diagram of FlexE
Agreement ties up N number of 100G optical module, forms a N*100G transmission channels, and the business for being equivalent to N*100G optical module passes
Speed is passed, the transmitting demand of N*100G business has both been met, also solves the problems, such as the economic value of business transmitting.Flexible Ethernet
Group (FlexE Group) refers to the group got up by 1 to N Ethernet PHY signal binding (Bonded), one
A flexible Ethernet group client (FlexE Client) refers to the ether stream based on MAC signal rate, can mismatch and take office
What Ethernet PHY stream, the client's MAC rate that can currently support have 10,40 or m*25Gb/s.Wherein, flexible Ethernet
Interlayer (FlexE Shim) is used to for client signal being mapped to or demapping is to FlexE Group.In Fig. 1, flexible Ethernet
Optical physics channel in group between the optical module and optical module at both ends constitutes a communication link, and the optical module of both ends of them is made
For the member of flexible Ethernet group.
Since FlexE agreement is that multiple optical physics channels are bundled into the logical channel of business transmitting, when an object
When breaking down, then entire logical channel all breaks down in reason channel, and such as a physical channel is interrupted, then entire logical channel is all
It interrupts, as shown in Fig. 2, the reliability of logical channel entire so just reduces, the probability that logical channel breaks down is single
Break down the integral multiple of probability for a physical channel, and multiple is exactly total binding number of physical channel.RPF is defined in FlexE agreement
(remote phy fault, distal end phy failure) information, for the optical fiber that the failure of the phy of local terminal member is passed through opposite direction
Pass to opposite end member.Local terminal member and opposite end member are the transmitting distal end phy fault messages between a pair of of optical fiber.Actually answering
In, the transmission-receiving function of optical module is integrated in together, is entirety, if optical module failure (namely member itself goes out
Show failure), then it receives and dispatches both direction and all interrupts, since the direction of hair is also interrupted, just sent without normal direction opposite end remote
Phy fault message is held, the distal end phy fault message of opposite end transmission can not be also received；In addition, since transmitting-receiving optical fiber wiring is to walk together
One physical pathway, when because the various mechanical reasons such as ditching cause fiber break, the optical fiber for receiving and dispatching both direction all occurs
It interrupts (namely optical physics channel failure where member), therefore can not also transmit distal end phy fault message.Therefore, at present
Flexible Ethernet is when a certain member is when (namely when there is bi-directional failure) receiving and dispatching both direction while interrupting, and FlexE is assisted at present
This earth fault for discussing and deciding justice can not just be transmitted to opposite end member, can not also receive the fault message of opposite end member, lead to local terminal

Scheme to facilitate the understanding of the present invention, the present embodiment combine a kind of specific FlexE agreement to do into one the present invention
Step illustrates.N in this example, in flexible Ethernet group comprising 4 physical links namely the flexible Ethernet group in Fig. 1
Value is 4.It certainly, may also be 2 or 3 or 5 etc., specific value is then needed according to specific application according to practical application
Scene is flexibly set.
In optical mode is fast, the data message of 100G is that data packet messages are carried out to 64/66 coding before sending, by 64 ratios
Special data block is extended to the block of information of 66 bits, and increased 2 bit is located at front, as the opening flag of 66 bit blocks, so
It is sent in a manner of 66 bit blocks from optical port afterwards.When receiving, optical port identifies 66 bits from the data flow received
Then block recovers 64 original bit datas from 66 bit blocks, re-assemblies data message.FlexE agreement is in
64 bits are to 66 pieces of conversion layers, in *, the data block of 66 bits are ranked up and are planned, as shown in Figure 10, for 100G industry
Business, every 20 66 bit data blocks are divided into a data chunk, and totally 20 data blocks in every group represent 20 time slots, each
Time slot represents the business speed of 5G bandwidth.It is every to have sent 1023 data chunk (1023*20 when sending the data block of 66 bits
A data block), it is inserted into a FlexE expense block, such as black block in Figure 10.After being inserted into expense block, continues to send data block, send
After complete second 1023*20 data block, it is inserted into expense block, and so on, it, can week in this way during sending data block
It is inserted into phase property expense block, the interval of two neighboring expense block is 1023*20 data block.
When being bundled into a big logical channel using the multiple physical channels of FlexE protocol realization, FLEXE agreement compares 66
Special data block is ranked up and plans, every 20 66 bit data blocks are divided into a data chunk, totally 20 numbers in every group
According to block, 20 time slots are represented.Such as Figure 11,4 physical channels are bundled into a logical channel, when transmission, by first data
Block group (20 data blocks) is sent on first physical channel, sends second for second data chunk (20 data blocks)
On a physical channel, send third data chunk (20 data blocks) on third physical channel, by fourth data
Block group (20 data blocks) is sent on the 4th physical channel, then sends the 5th data chunk (20 data blocks) to
On first physical channel, and so on, it is logical averagely, poll to send all data groups (20 data blocks) to 4 physics
On road.Data block on 4 physical channels is perfectly aligned when sending, and is all at interval of 1023 4 physical channels
Data chunk is inserted into expense block simultaneously on 4 physical channels, and the data block, expense block on such 4 physical channels are complete
Alignment.In receiving end, each physical channel individually receives data block, then determines expense block position.Each physical channel
On the basis of expense block position, the data chunk of 4 physical channels is realigned.The data chunk of 4 physical channels is with expense
It after being aligned on the basis of block position, resequences according to the inverse process of poll distribution when sending: first being taken from first physical channel
First data chunk (20 data blocks) sequence after expense block in front, then obtained from second physical channel
First data chunk (20 data blocks) is sorted later after expense block, then expense block is obtained from third physical channel
First data chunk (20 data blocks) sequence later is after secondary, then the after obtaining expense block in the 4th physical channel
One data chunk (20 data blocks) sequence is finally, then process above, elder generation take from first physical channel again
After second data chunk (20 data blocks) sequence time after expense block, expense block is obtained from second physical channel
After second data chunk (20 data blocks) sequence time later, and so on, by the data chunk weight of four physical channels
New sort is at a big logical channel data chunk.In this way, 4 physical channels can be tied up, is formed
One big logical channel.For client traffic, a big logical channel is only perceived, is passed by big logical channel
Business is passed, four physical channels without knowing bottom.
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 Figure 12, 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 far-end fault 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
It 12 filled black parts can be using any one or more with reserved field in expense frame when selecting reserved field
Expense block in.
Every 32 FlexE expense frame forms a multi-frame, indicates that the sequence of each frame in multi-frame is closed by OMF bit
System, such as Figure 13.OMF bit is 0 in 16 frames, is then 1 in subsequent 16 frame, with this circulation change, every 32 frame variation one
It is secondary.OMF bit is that 0 frame is the first frame in multi-frame for the first time, with this be the second frame, third frame ... the 32nd frame.Phy
Map transmitted in every frame 8 information (indicate corresponding 8 phy whether with, " 0 " indicates unused, " 1 " indicate with), 32
Frame can transmit 256 (0-255) information, transmit 256 phy number with situation.For example, No. 0 position is " 1 ", then table
Show the member of phy number=1 with；No. 15 positions are if it is " 1 ", then it represents that the member of phy number=15 with.
Client Calendar indicates that each time slot belongs to that client, divides Client Calendar A and Client Calendar
B, only one is effectively between A, B when work.There are 20 time slots, a multi-frame there are 32 frames, because 20 frames transmit 20 time slots before this
Customer information, behind 12 frames content as reserved field.Other byte contents are not directly dependent upon with scheme in expense frame,
This is repeated no more.
FlexE agreement ties up multiple physical channels, forms a big logical channel, meets the business of big flow
Transmitting needs, but when a physical channel is broken down, then the business of entire logical channel is all impacted.If one
Physical channel is interrupted, then the business of entire logical channel is also interrupted, and the reliability of business transmitting reduces.In FlexE
In agreement, RPF information is defined, RPF information can only transmit the far-end fault information of this member, can not transmit the event of other members
Hinder information, when two-way all interruptions of this member, both ends can not transmit the fault message of opposite end.In opening for FlexE protocol definition
In the reserved field for selling field, increase member's indicating fault content, such as Figure 14, RMF (remote member fault) word
Section for the fault message of all members is passed to distal end, and is transmitted especially by all members of local terminal to opposite end, in this way
As long as a paths are normal, so that it may fault message be passed to opposite end, bi-directional failure is avoided and cause not transmitting
The problem of failure.
Figure 14 is the example 1 of the present embodiment, increases RMF (remote member fault) field in expense frame,
For transmitting the fault message of all members of local terminal.In example 1, RMF uses a byte (8 bit wide), with a bit table
The fault message (if " 1 " indicates faulty, " 0 " indicates normal) for showing a member, can transmit the event of 8 members in a frame
Hinder information.By multi-frame structure, subsequent frame continues to transmit the fault message of other members, and a multi-frame can transmit 256
The fault message of a member.
Figure 15 is example 2 of the invention, in the case where seldom only 8 members of total number of members, RMF in expense frame
Field can once transmit all members.If needing equal 32 frames that could transmit again, the waiting time using multi-frame structure
It is very long.In the case where member is fewer, multi-frame structure is not transmitted, but every frame is all transmitting all members.
Figure 16 is example 3 of the invention, in the case where failure number of members is seldom, while transmit faulty member and
Trouble-free member causes faulty member waiting time in transmitting longer.In example 3, only transmit it is faulty at
Member, does not transmit trouble-free member.Two information, the phy of failure member number and fault message are transmitted when transmitting.Often
Frame transmit a failure member fault message, then transmit next member's failure fault message ... the last one therefore
The fault message for hindering member, is recycled with this.
It is merely given as several examples above, when specific implementation there are all kinds of flexible ways, but belongs to the protection model of the patent
Enclose, such as: (1), the fault message of member can be 1 bit to indicate, be also possible to multiple bits；(2), transmitting can be with
It is the fault message of member, being also possible to can be with the status information of characterization failure situation；(3), a frame can transmit a member
Information, the information of multiple members can also be transmitted.(4) member's failure indication information can be only transmitted, member can also be compiled
Number and failure indication information transmit together.
