Description

The failure notification and acquisition methods, device, communication equipment of flexible Ethernet
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 Mutually isolated between member and distal end member, every end member, which only knows, is locally detected failure, but can not know opposite end member Malfunction, cannot notify opposite end member stops to send business on failure path, business can not be switched on trusted path.

S301: each failure member currently to break down in local terminal member in flexible Ethernet group is obtained.
In the present embodiment, obtain in flexible Ethernet group that failure has occurred in which member in local terminal member, it can be by sentencing It is disconnected to determine from the data cases that the physical link where each member receives, if such as being not received by where the member The data that physical link is sent then can determine that the member breaks down.In the present embodiment member break down including but Physical link failure where being not limited to member's faults itself and member.
S302: the fault message of each failure member is separately added into the data to be sent of target members.
Target members in the present embodiment include at least one member in local terminal member except each failure member itself.This Embodiment is directed to each target members, and the fault message of each failure member is all added in its data to be sent.Herein to Sending data can be dedicated for carrying out the various data of fault message notice, be also possible to business datum or institute's business number According to the various data of other miscellaneous functions of transmission.
Member in the present embodiment except each failure member itself refers to other members except failure member, it is assumed for example that Member's A failure then selects at least one as target members in other members at least in local terminal member in addition to member A, Such as member B.The member B selected at this time may be the member to break down, it is also possible to the member of failure have occurred.Cause This can directly select local terminal member all in flexible Ethernet group in a kind of this example, and target members include spirit at this time All local terminal members, can maximumlly guarantee that the fault message of failure member can successfully be sent in this way in Ethernet group living To opposite end, except bi-directional failure occurs for not all local terminal member.Certainly, being specifically chosen which member can be with as target members It is flexibly set according to practical application scene.
S303: by the data to be sent of each target members by each target members the corresponding opposite end into flexible Ethernet group Member sends.
Namely opposite end on the physical link is sent for data to be sent by the physical link where each target members Member.
As described above, the fault message of failure member can be added to the data to be sent of target members in the present embodiment In, the corresponding member in opposite end is sent to by target members.Data to be sent in the present embodiment can be to carry out The data of fault notification, such as various fault notification messages are also possible to business datum or institute's business datum send together its His various auxiliary datas.For example, the fault message of each failure member can be added in the expense frame that data to be sent include, one A expense frame is made of multiple expense blocks, thus specifically can by fault message be added expense frame at least one with reserved word In the expense block of section.The fault message of each failure member is added at this time in the data to be sent of target members includes: with expense Frame is unit, and the fault message of each failure member is added at least one expense block with reserved field of an expense frame In.In another example the fault message of each failure member can be added in the multi-frame that data to be sent include, target members at this time Data to be sent include the multiple expense blocks for constituting expense frame, and N number of expense frame constitutes a multi-frame will be each as unit of multi-frame At least one the opening with reserved field at least one expense frame that a multi-frame includes is added in the fault message of failure member In pin block, N is more than or equal to 2, is provided according to existing protocol, and 32 expense frames constitute a multi-frame.Which of multi-frame is specifically added It can also flexibly be set according to specific requirements in expense frame.And the reserved field of which expense block is specifically occupied, and specifically account for It can flexibly be set according to specific application scenarios with how many reserved field.
In the present embodiment, fault message is added in expense frame as unit of expense frame, or is added as unit of multi-frame In multi-frame, can flexibly be set according to concrete application scene, for example, can according to break down membership, fault message have Body includes the flexibly setting such as occupied length of content.
In the present embodiment, the fault message of failure member may include failure member identification, at this time then can be only by hair The member identification for having given birth to the member of failure is added in expense frame or multi-frame.In another example in another middle example, failure at The fault message of member may include failure member identification and failure indication information, can know the member of all members at this time Other information is added in expense frame or multi-frame, and the member for failure has occurred can then add failure indication information, for not The member to break down does not add failure indication information then, or addition state is normally to indicate information (in some instances It different can add).Fault message specifically uses failure member identification, or uses failure member identification+failure Indicate that the mode of information can also flexibly be set according to concrete application scene.Failure member identification in the present embodiment can be with It is member's number or the various information of other energy unique identification members.Failure indication information in the present embodiment, which can be, to be used for Any information of failure has occurred in instruction.
In this way, in local terminal, for the fault message of the member to break down, can by other except failure member at Member is sent to opposite end, to notify the fault condition of opposite end local terminal, carries out failure negotiation to be conducive to both sides, alerts and make phase The safeguard measure etc. answered, the safeguard measure in the present embodiment including but not limited to reject faulty link from group, and standby When with link, reserve link is added.Correspondingly, the fault method that opposite end obtains flexible Ethernet is shown in Figure 4, comprising:
S401: the failure notification method that opposite end member in flexible Ethernet group is based on flexibly Ethernet as described above is received Transmitted data.
S402: from the fault message for extracting each failure member to break down in the member of opposite end in the data received.
When the fault message of the failure member of opposite end is to be added in expense frame or multi-frame to send over, from the number received The fault message that each failure member to break down in the member of opposite end is extracted in then includes: to extract from the data received Corresponding expense frame and multi-frame out, and extracted from the reserved field of expense frame or the corresponding expense block of multi-frame and be out of order member's Fault message, and then which physical link the case where breaking down in conjunction with local terminal member analyzes (comprising physical channel and object Manage channel both ends optical module) have occurred bi-directional failure (may be physical path failure, it is also possible on the physical link at Member's itself fail).For the physical link of bi-directional failure has occurred, it can be rejected from flexible Ethernet group, be kept away Exempt from business still to send on the physical link of the failure, although reducing the bandwidth of flexible Ethernet group logical channel at this time, Breaking down with a physical channel causes the result of whole service disconnections to be compared, and this processing mode is apparently more rationally real With.It, can will be spare after the physical link for rejecting failure in addition, spare physical link also can be preset in the present embodiment Physical link be added in the flexible Ethernet group, namely faulty physical link is replaced with spare physical link, then The auto switching function after physical link breaks down may be implemented, realize the automatic recovery of business, it in this way can be significantly Ground improves the reliability of FlexE business, improves application value.For example, with reference to shown in Fig. 5, flexible Ethernet group member A and right It holds the failure of the physical link generation where member B and is removed, spare physical link is added in the flexible Ethernet group, To realize the replacement of failed physical link, the automatic recovery of business is realized, improves the reliability of FlexE business.
The present embodiment sends opposite end for the fault message of failure member by other members except failure member, thus Fault message cannot be transmitted to the problem of opposite end when avoiding the occurrence of bi-directional failure.Allow both-end according to the fault condition of opposite end It is alerted accordingly and protection is handled, promote the reliability of FlexE business.

The failure that second memory 92 is used to store flexible Ethernet obtains program;
The failure that second processor 91 is used to run the flexible Ethernet in second memory obtains program, strictly according to the facts to realize Apply the step in the failure acquisition methods of flexible Ethernet shown in example one kind.It should be understood that first in the present embodiment Communication equipment and the second communication equipment can be with various optical communication equipments or servers etc..
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.
