Specific embodiment

It is right below in conjunction with the accompanying drawings and the specific embodiments to make the object, technical solutions and advantages of the present invention clearer The present invention is described in further detail.It should be noted that the embodiment and enforcement in the case where not conflicting, in the application Feature in example can mutual combination in any.

The data flow of specific bandwidth has been arrived after MAC layer, parallel data stream is formed through MII interfaces, by these data flows Be combined into the data signal of 64 bits, subsequent FlexE SHIM carry out 64B/66B codings to the data that MII interfaces come, generate by 66 bit block dimerous a, part is the synchronous head of 2 bits, and another part is the payload of 64 bits, should The logic serial stream of 64B/66B blocks is referred to as FlexE Client (FlexE clients) in the flexible ethernet technologys of FlexE.

Flexibly Ethernet includes FlexE group (FlexE groups), FlexE Client (FlexE client) and FlexE Calendar (FlexE Calendar time slots).

FlexE group are made up of 1 to n 100GBASE-R ethernet physical layer device.Each physical layer device makes With most of PCS (Physical Coding Sublayer, physics described in the 82nd article of ieee standard 802.3-2015 drafts Coding sub-layer) function, including the distribution of PCS passages, path marking insertion, alignment and correction.In each PHY of FlexE group The FlexE payload of upper carrying has the form of the logic serial stream of legal 64B/66B blocks, by PCS channel alignment labellings Except taking, therefore it is that FlexE payload can not be carried by the field that PCS channel alignments labelling takes.

Each FlexE Client is a 64B/66B block logic serial streams for representing an ethernet mac layer.64B/ 66B codings are according to ieee standard 802.3-2015 Figure 82-4.

The running of FlexE mechanism uses Calendar, and 66B blocks position is distributed on each PHY of FlexE group to often Individual FlexE Client.Calendar is the time slot for possessing 5G granularities.

For a FlexE group of the 100GBASE-R PHY including n binding, master Calendar's patrols It is 20n to collect length.

Flexibly the SHIM layers (bed course) of Ethernet by FlexE Client data flows by being mapped to corresponding Calendar Time slot sets, realize the basic function of flexible Ethernet.

First, the present invention provides a kind of method, realizes based on the OAM of FlexE Client;

Solution is converted into the FlexE Client's belonging to the PCS Lane from the oam state or business of each PCS Lane The problem of oam state or business, the oam state or business of each PCS Lane are included but is not limited to, based on PCS Lane Block lock, signal reduces (loss of signal), based on the BIP error monitorings of PCS Lane, PCS_SD_BER, Alignment lock etc..

Solve following problem:

Some existing OTN mappers/demappers (mapper/de-mapping device) are not complete and LF or RF orders Collection PCS code words are transparent, may mistake indivedual LF sent for FlexE Client or RF so that these LF/RF for being mistaken When being transmitted as the LF and RF as whole link, whole linkdown is caused to fall, particularly using not perceiving On the premise of FlexE is transmitted, carry one group of low rate FlexE Client service and use less than complete PCS code words transparent mapped In scene.

The technical scheme for being used is as follows:

In order to realize the OAM(Operation Administration Maintenance) based on the FlexE Client to binding 100GbE PHY, need to realize to single logical The monitoring in road, therefore OAM process is placed on into MII, and (MII here is to be referred to as, rather than only only includes a certain specific MII types Such as, CGMII interfaces) after interface, meanwhile, the 64B/66B codings being placed in FlexE SHIM layers are extracted and inserted for convenience Before process, as shown in Figure 10.It is summarized as claim:OAM process is placed on after MII interfaces, the 64B/66B in FlexE SHIM layers Before coded treatment.

The PHY numbers and numbering of flexible ethernet port binding are obtained, to facilitate specific FlexE Client and correspondence PCS Lane carry out correspondence, and to protection below and recover function use;

The on position of on position and alignment marker to OAM blocks is all to be located at PCS Lane passages, is produced It is raw identical with alignment marker with the frequency of insertion;

For compatible existing protocol, newly-increased OAM data block using 66bit size, to should OAM data block Control code control routines are located at-1-Control codes of Table 82 in ethernet standard IEEE P802.3ba In member-retaining portion, that is to say, that in the table in the value of Control Code fields, those values not being defined, select one The value of the Control Code of the individual OAM Control Character to be used as the present invention.

The position that OAM Information is deposited is as follows:

The OAM domains of the 24bit of Fig. 2;Or:

Management passage field (Management Channel) or newly-established field or guarantor in FlexE expense structures Section of writeeing down characters (Reserved).

By the corresponding relation for obtaining PCS Lane and FlexE Client, there is a certain oam state in PCS Lane and become When changing (such as certain failure) or needing to process a certain OAM business, according to the corresponding relation, it may be determined that target FlexE Client, the oam state for arranging target FlexE Client is malfunction or arranges related OAM Information, and OAM Information is deposited Position as previously described.By these modes, solve from the OAM of each PCS Lane and realize and condition conversion is the PCS The OAM realizations of the FlexE Client belonging to Lane and the problem of state.

After belonging to the oam state of all of PCS Lane of certain FlexE Client and all recovering normal, by this The oam state of FlexE Client carries out reverting to normal condition.

The oam state or business of each PCS Lane is included but is not limited to, based on the block lock of PCS Lane, Signal reduces (loss of signal), based on the BIP error monitorings of PCS Lane, PCS_SD_BER, alignment lock Etc..

Then, solve in flexible Ethernet bundling port, it is caused when part FlexE Client or part PHY failure Bandwidth wastage problems, this needs to realize being done based on the local terminal failure/far-end fault LF/RF handling processes of flexible Ethernet to existing Modification, this problem is described as follows:

As one or more the PHY failures for belonging to FlexE group, continuous far-end fault command set (Remote Fault Ordered Set) by the FlexE groups being assigned to inside the calendar time slots of arbitrary FlexE Client It is sent back to, by set by the FlexE expenses by each PHY, it (is exactly remote that these PHY are directed towards the FlexE groups of distal shim for RF positions The PHY at end) in.

This way simply simply binds to carry the stream of bigger speed to the transmission and the transmission that do not perceive FlexE Situation, be not problem, because the failure of single high speed FlexE Client is equivalent to the failure of the FlexE group.But It is that, if on the premise of using FlexE transmission is not perceived, one group of low rate FlexE Client service of carrying is used and has been less than The transparent mapped of full PCS code words, such case is it is possible that problem.Such as, two be bound into flexible Ethernet two PHY, can carry multiple FlexE Client inside it, when one of PHY breaks down, may result on two PHY Other FlexE Client fail, even some FlexE Client simply use another normal PHY.By this Bright method can solve the problem.

Solution is as follows:

By the oam state or business of PCS Lane, and FlexE Client and PCS Lane correspondence relationship informations, can be with The FlexE Client that need carry out OAM process corresponding with the PCL Lane is obtained, in the FlexE Client business correspondence Physical layer insertion LF or LLF (LF illustrate:Ethernet Local Fault Ordered Set), by time by the target (LLF is that for LF, past LF is directed to whole link and sends out LF, the present invention to the LF or LLF of FlexE Client Refer to send out LF to some scope, so being called LLF, middle L can be belonging to the institute of certain FlexE Client sometimes Gap, or certain electric lane passages set, can also be the lane passage set of certain light) upper-layer protocol is reported to, then Upper-layer protocol belonging to local FlexE Client sends RF or RLF to opposite end, and (RF illustrates:Remote Fault Ordered Set), whole time slot existing FlexE technologies being adopted, to the FlexE group belonging to the FlexE Client Send the mode of RF, be changed to only to be transmitted to all time slots belonging to the FlexE Client (L in RLF be refer to Some scope, can both be belonging to all time slots of certain FlexE Client, can also be to certain electric lane passage Set, can also be that the lane passage set of certain light is transmitted), there is corresponding field field in the expense structure of FlexE The information such as numbering, the lane channel numbers of the PHY for breaking down are informed, OAM Information is filled into of the present invention in expense In field.

The equipment of opposite end is being received after RLF alarms are indicated just by the original data of empty data block insertion replacement at this It is transmitted in Calendars time slots occupied by FlexE Client.Said process is realized to failure FlexE Client OAM management.

In addition, also to solve the problems, such as to send the protection and recovery under failure condition.

The method wherein protected and recover includes:

To need FlexE Client to be protected to arrange standby PHY, the numbering of the PHY is notified to manage to FlexE SHIM Reason entity;

As it was previously stated, if it find that FlexE Client have OAM failures, then the oam state of FlexE Client is set to Malfunction, the position of write is with noted earlier;

Standby PCS Lane are replaced into the PCS Lane in OAM malfunctions so that do not result in whole link paralysis; Or:

Standby PHY is replaced into the PHY belonging to target FlexE Client so that do not result in whole link paralysis.

After the OAM modules of FlexE Client are detected and enable standby PHY, all of failure PCS belonging to it The OAM of Lane reverts to normal condition, then the oam state of FlexE Client is set to into normal condition, and the position of write is same It is noted earlier.If standby PCS Lane or standby PHY enable failure, the oam state of the FlexE is continued to remain failure State.
