Embodiment 3
The present embodiment is the alternative embodiment of the application, for combining specific implement scene to carry out the scheme of the application
It is described in detail.
In the scheme of the present embodiment, CBR business is carried by FLEXE, can be true when distal end reception CBR business is problematic
It surely is that reason leads to the CBR traffic issues.
Present embodiments provide a kind of method that CBR business realizes business monitoring on FLEXE, comprising:
Step 1: in S block, marking off one section of field as CBR business monitoring in the field location of reservation.
Step 2: in T block, also marking off one section of field as CBR business monitoring in the field location of reservation.
Step 3: in local terminal, block statistics and sequence number in the monitoring information of CBR being placed on S block, the school bip8 in monitoring information
It tests and is placed in T block, sent by FLEXE.
Step 4: in distal end, extraction block is counted from the S block received, sequence number is counted with local block respectively, sequence
It number is compared.The bip verification that bip8 verification and local computing are extracted from T block is compared.To obtain the prison of CBR business
Control information.
Below by taking the CPRI business with CBR characteristic as an example, the features of the present invention and technology contents are illustrated, when specific implementation
As long as meeting the business (such as E1 business) of CBR characteristic, the scope of the present embodiment is belonged to.
If transmitting forward pass business using the load bearing equipment of FLEXE is supported, just there will be CBR business specific
CPRI be transmitted as the Client of FLEXE.CPRI is without ether network simulation, and directly at L1 layers, PCS is encoded eventually
Knot, regenerates or is converted, so that meeting the PCS coding rule of FlexE Client, passed in the time slot of FLEXE Shim
It send.
If CPRI business during transmission, is lost the data content of some block or some block by the modification of mistake
, the CPRI business of distal end parsing will be problematic, since the CPRI frame of FLEXE carrying itself is without OAM (operation, management, dimension
Shield) instruction, it is mutually isolated between local side and distal end, just it can not also navigate to bottom is where to malfunction at this time, what reason is led
The error of CPRI business is caused, is that block is lost or block content is modified, the source of error cannot be found, can not just solve failure.
Once the CPRI business of parsing goes wrong, will can not determine.If additionally adding the monitoring information of some positioning, pass through S
Still unused retention position is sent out in block and T block, once business is problematic, opposite end will be known according to these monitoring informations
Road is caused by what reason, to solve failure.
S block one shares 8 bytes, has 7 bytes to retain, such as Fig. 7, Fig. 7 are that each byte of S block defines in the present embodiment
Schematic diagram.Retention position in S block increases the sequence number of the block statistics and 2 byte of 2 bytes, for monitoring
Whether lost block is had.
T block one shares 8 bytes, has 7 bytes to retain, such as Fig. 8, Fig. 8 are that each byte of T block defines in the present embodiment
Schematic diagram.Retention position in T block increases the bip8 verification an of byte, for monitor CPRI block data content whether by
Modification.
Block statistics is extracted from the S block received when distal end to compare with the block of local computing statistics, when the two is inconsistent,
It is known that between a S and T block there is CPRI dropout of data block.
When abstraction sequence number compares with the sequence number of local computing from the S block received for distal end, the unequal feelings of the two
Under condition, if the CPRI business restored is correct, it is only lost S block；If restore CPRI business it is incorrect, be lost S block and
CPRI business datum block.
When abstraction sequence number compares with the sequence number of local computing from the S block received for distal end, when the two is equal, and
And the block that block statistics and local computing are extracted in the S block received is counted and is compared, the two is also consistent, and from the T received
The bip verification that bip8 verification and local computing are extracted in block is compared, and the two is unequal, if the business restored is abnormal,
CPRI data block contents are modified.
When abstraction sequence number compares with the sequence number of local computing from the S block received for distal end, when the two is equal, and
And the block that block statistics and local computing are extracted in the S block received is counted and is compared, the two is also consistent, and from the T received
The bip verification that bip8 verification and local computing are extracted in block is compared, and the two is unequal, if the business restored is normal,
There is T lost block mistake before this T block.
The specific example that the present embodiment CBR business realizes the method and apparatus of monitoring on FLEXE is given below:
Sending direction counts the data block (one piece of 64bit) between S block and T block, the bit being placed in next S block every time
In [47:32], i.e., data block number (including S block and the T of block statistical counting in current S block between a upper S and T block
Block), as shown in figure 9, Fig. 9 is the schematic diagram that the block statistics in the present embodiment in S block calculates.Receiving direction, calculate each S block with
Data block between T block, obtained local count value compares with the block extracted from next S block statistics, if unequal,
Then block error statistics counter is reported CPU plus difference between the two by block error statistics counter.When block error statistics meter
Number device is not 0, then having CPRI dropout of data block between a upper S and T block.
Sending direction, the bit [63:48] of S block is sequence number, since 0, every time plus 1.I.e. one (S+ data block (n block)
+ T) plus 1, as shown in Figure 10, Figure 10 is the schematic diagram that the series number in the present embodiment in S block calculates.Receiving direction often receives one
A S block, local sequence number add 1, and local sequence number is compared with the sequence number extracted from S block, if unequal, sequence
Number error count adds 1, and sequence number errors counting is reported CPU.It is not equal to 0 when sequence number errors count, if the CPRI industry restored
It does honest work really, is then lost S block；If the CPRI business restored is incorrect, it is lost S block and CPRI business datum block.
Sending direction carries out bip8 verification, verification to a upper T block and this S block and this all data block every time
Value is placed in the bit [55:48] in this T block, and as shown in figure 11, Figure 11 is showing for the bip8 verification in the present embodiment in T block
It is intended to.The last T block of extraction+this S block+this all data block are carried out bip8 verification, obtained school by receiving direction
It tests value to compare with the check value in this T block in verification domain, if unequal, bip8 error statistics counter adds 1.When
Bip8 error statistics counter is not 0, and block error statistics counter is 0 and sequence number errors count and are equal to 0, this three
Under the conditions of a, if the business restored is incorrect, CPRI data block contents are modified；If the business restored is correct, in this T
There is T lost block mistake before block.
Can have all kinds of flexible ways when specific implementation, comprising: meet CBR characteristic business (be not limited to CPRI business,
E1 business etc.)；Block static fields can any position in S block in reserve bytes；Sequence-number field can retain in S block
Any position in byte；Bip8 check field can any position in T block in reserve bytes.Block statistics and sequence number are not
It must be 16bit, be also possible to other bit bit wides.
