Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the specific technical solution of invention is described in further detail.The following examples are intended to illustrate the invention, but does not have to
To limit the scope of the invention.
Embodiment one
The embodiment of the present invention provides the interconnection method of a kind of Interlaken interface and FlexE IMP, and Fig. 1 is that the present invention is real
The implementation process schematic diagram for applying an Interlaken interface and the interconnection method of FlexE IMP, as shown in Figure 1, the method packet
Include following steps:
Step S101, by from Interlaken interface to data carry out framing, and to after framing data carry out
Coding, obtains coded data.
Here, Interlaken interface is explained first.
Interlaken interface is the high-speed interface of a kind of chip based on data packet transmission and chip interconnection, compared to tradition
10G Ethernet connection unit and system packet interface, Interlaken interface be suitble to 10Gbps or more high speed transmission,
Interlaken interface can be used in any number of serial link (or " channel "), and the number of active lanes usually supported is 256, can
To expand to 64K, and interface capability can be improved by adjusting the number of deserializer.Interlaken interface has
It is directly related with number of active lanes to imitate bandwidth.
During realization, the step S101 can be realized by following steps:
Step S1011, by since Interlaken interface to data, the lead code of 7 bytes, 1 byte frame
The frame end for according with (Start of Frame Delimiter, SFD) and 1 byte accords with (End of Frame Delimiter, EFD)
It is combined into a frame；
Here, the lead code of 7 bytes, SFD and EFD are pre-set.
The frame first symbol of the preamble data and 1 byte is carried out 8 byte-aligneds by step S1012；
It here, is 8 bytes by the number of data units of Interlaken interface, agreement provides that 8 bytes are a number
It is to be encoded for convenience, and lead data code and frame first symbol are also 8 bytes according to unit, is conducive to adjust interface
Bandwidth.
Data after framing are converted to Media Independent Interface (the 100Gb/s Media of 100G Ethernet by step S1013
Independent Interface, CGMII) format data；
Step S1014 encodes the data of the CGMII format, obtains coded data.
Here, to the data encoding of the CGMII format at 66 bits (bit) data.
Step S102, by the speed adjust of the coded data to preset Ethernet rate.
Here, it since the rate for the data transmitted in Interlaken interface is higher, is carried out pair with FlexE IMP at this time
It is needed when connecing by the speed adjust of coded data to preset Ethernet rate.
During realization, the step S102 can be realized by following steps:
Step S1021 determines the number N for needing the Inter-packet gap (Inter Packet Gap, IPG) being inserted into；
Here, the number for the IPG for needing to be inserted into is determined according to 12 bytes of Inter-packet gap average out to.In other implementations
In example, determines that the number for needing the IPG being inserted into can be realized by following two step: obtaining the data packet of the coded data
The byte number of Inter-packet gap between number and data packet；According to the packet between the data packet number and data packet of the coded data
The byte number in gap determines the number for needing the IPG being inserted into.
For example, it is assumed that there is 3 data packets, the byte number of the Inter-packet gap between current data packet is 20 bytes, due to 3
There are two Inter-packet gap, 12 bytes of Inter-packet gap average out between data packet, then 24 bytes are needed altogether, due to current parlor
The byte number of gap is therefore 20 bytes need to be inserted at this time 4 IPG.
In other embodiments, IDLE also can be inserted, 1 spare bits (IDLE) is 66bit block, including 8 IPG.Such as
When the multiple that the IPG number that fruit needs to be inserted into is 8, the number of the IPG of insertion can according to need, determine the IDLE for needing to be inserted into
Number.
Step S1022 is inserted into N number of IPG in the packet tail of the coded data, using local clock by the coded data
Speed adjust is to preset Ethernet rate.
Step S103 scrambles the coded data after the speed regulation, and sends FlexE's for the data after scrambling
IMP mapping block.
Here, signal scrambling technique is explained.Scrambling is a kind of to encode by data permutation or to data
So that the method for its randomization, this technology mix pseudo-random sequence with original code rate, to realize the mesh such as conversion, direct current equilibrium
, but allow for carrying out data recovery by descrambling.During realization, it can be scrambled by scrambler.
Scrambler includes two types, respectively self-synchronous scrambler and side scrambler.Self-synchronous scrambler directly will be defeated
Enter data as scrambler state, does not need resetting and synchronizing process.The buffer status and transmission data exclusive or of side scrambler
Next state is constituted, this needs to carry out " resetting/synchronous " scrambler state between input and output.
The advantages of self-synchronous scrambler, is not needing using any synchronization character.The function of scrambler is added in transmitting terminal
It disturbs, is receiving descrambling, replying initial data.But self-synchronous scrambler need two feedback ends, in this way can reproducible it is wrong twice
Accidentally.In order to avoid this phenomenon, Interlaken interface protocol uses side scrambler, can be avoided using self-synchronous scrambler and
Caused error code replicates problem.
In other embodiments, the step of the speed adjust by the coded data is to preset Ethernet rate
Later, the method also includes:
Judge whether to detect preset abnormal conditions occur；
There are preset abnormal conditions if detected, the coded data is replaced with into local error code (local
fault)。
Here, it detects that preset abnormal conditions can include but is not limited to: detecting GFP CSF signal, detects OTN
Layer link fault signal (ODU2AIS, ODU2-LCK, ODU2-OCI etc.) detects 100GE input signal failure (LOS) or OTN
Layer link breaks down (ODUk AIS, ODUk-LCK, ODUk-OCI etc.).
The citing of the above abnormal conditions is merely illustrative, in the actual implementation process can be according in IEEE802.3
Protocol definition replaces the abnormal conditions of local error code.
In the interconnection method of a kind of Interlaken interface provided in an embodiment of the present invention and FlexE IMP, first will
From Interlaken interface to data carry out framing, the data after framing are encoded, coded data is obtained；Then
By the speed adjust of the coded data to preset Ethernet rate；Finally the coded data after the speed regulation is added
It disturbs, and sends the data after scrambling to the IMP mapping block of FlexE.So, it is possible realize Interlaken interface with
The docking of FlexE IMP.
