Abstract

The present invention discloses a method and device for data mapping. The method includes: encoding Fiber Channel (FC) data into valid data packets, and outputting the encoded valid data packets, wherein the 0th bit of the 0th byte of each valid data packet is 1; receiving and buffering the valid data packets, and outputting the buffered valid data packets as Optical channel Payload Unit-k (OPUk) data when the number of all the buffered valid data packets is not less than a predetermined threshold. The present invention also discloses a method and device for data demapping. Application of the present invention can avoid a Generic Framing Procedure (GFP) encapsulation process, thereby reducing complexity of the implementation of an FC system.

Description

Mapping method and device, and mapping method and device

This relates to optical communication teaching, and in particular to methods and devices for teaching God mapping, and methods and devices for teaching mapping. Background

At present, the 仟 channel (C, be Cha e ) is in the middle, because the rate of C is lower than (OT, Op ca Ta po ewo ), so C cannot be directly mapped to OT, especially 1 C, because the rate of 1 C is only 1.0625Gbp, which is 42% of the channel teaching sheep (O, Op ca Cha e aa), if the direct rate is matched, the wave is 58%.

Existing wood, the usual practice is in , will G C

The general procedure (G P, Ge e c a g oced ) encapsulation rate is assigned to the channel sheep (OP, Op ca Cha e ayoad) rate, and then P, then the channel sheep (T, Op ca Cha e Ta po), the most OT. Not only the way, but also the G FC of the sheep. However, in the presence of large-capacity cross-over wood and communication group (T) in G7 9, users can eliminate the need to assign the 1 C G package rate to the rate of P, and can directly package the 1 C G package.

Match P, then P, then

T, the most OT.

The way to go, but East said, in C, it is now necessary to first set the CGP encapsulation rate to OP, then OP O, then O OT, the most T, but, GP package, C system is also very, and more resources. content

5 In this case, the main purpose of this is to provide a method and device for mapping the gods, and a method and device for teaching the mapping, and to reduce the C system.

For the purpose of the purpose, the wood plan is

God's mapping method, including

C is valid, effective, effective 0 of 0

Receive valid, all valid not less than, will be the effective force OP.

Among them, C will be effective

5 The 9 C's C contains 8 valid, where, the valid 0 in the 0, 0 and the remaining 7 are in turn C, and the rest are in turn C is valid.

Among them, the method steps include all the teachings of Zhanyi are less than, all, will be the full effort OP

0.

Wherein, in the OP, the method step includes

Receive OP, will receive OP O, then O

OT.

God's mapping method, including

5 0 in 0 0 of OP, OP force is valid Effective

Receive valid, will receive a valid C.

Among them, will receive a valid C

Will contain 8 of C 7 to 9 .

The method step includes 0 0 of the received OP in the OP, and the OP is full and full.

Wherein, before the OP force is valid or full, the method step includes parsing O in the OT, and then

Parsing OP out.

a device for mapping gods, including compilation, rate, and control.

, valid for C, valid, effective 0

The rate, the received, and all the teachings are not less than the effective force of the OP

All of the teachings are less than, to the control control, at the rate of control, to the rate control rate, near the root received control, all, will be the full force OP.

Step, the device includes O and OT, where O, the OP at the receiving rate, will receive the OP O OT, in receiving O out of O, will receive O OT.

The mapping device includes a solution, where, in the receiving OP, 0 0 of the received OP, OP full, all received 0 0 of the OP, the OP force is valid, valid

, valid after receiving, will receive a valid C.

Step, the device includes OT and O, where OT, parses O O in the received OT, and receives OP from the received OT, and parses the OP in the received O.

Existing wood uses GP encapsulation and rate, comparison, and resource is relatively large, but this only needs to perform and rate step can be C to OP mapping, just perform the resolving step to OP to C demapping, compare sheep, and reduce C, more resources. 1 force this C OP mapping mapping method of the schematic diagram 2 force this C rules

It is indicated by the sheep of the C of the C. Hugh way

The following is a detailed description of the wood scheme.

As shown in Figure 1, the method of mapping this C OP mapping includes the following steps

In step 101, C is taught, and 0 of 0 is.

Hugh will divide 9 C into 8 , where 0 in 0, 0 in the remaining 7 in order of C, and the rest in order for each C to be valid.

In this paper, the full force mentioned below is effective for the force formed by C.

The rules of C are described in detail below in conjunction with 2. C 9 (b ), which contains 8 valid and . C is arranged in order, as shown in the upper part of 2, representing 1 , each C, the bottom of each is C, and the top is C. , move C to the front to form 0, because only, so 0 at 0 fixed padding, it forms 0. In addition, C's 8 is effective, and the media contains 8 valid, 2 times The half is shown.

In addition, the total 0 0 of 0 is specified, and this is all. complete

Fill the same rate as C and OP, which is also empty. Among them, there are different, can be 0, 1 or 2, and different represent different P rates, etc., and the existing wood will not be described here.

Step 102 104, receiving valid, all valid If it is less than, if it is, then it is full, and then proceed to step 105. Otherwise, it is valid.

Steps 102 to 104 rate, rate out of valid or full OP.

In addition, because the rate of OP is relatively fast, there may be a valid empty condition, so the pre-, effective is less than, the stop is effective, and the whole, to OP

. Among them, the size of the value is determined by the rate of C and OP, and the value of the value is the size of the rate in which the value can be required.

Steps 101 to 104 show the mapping from C to OP.

Step 105 106, receiving the OP, receiving the received OP O receiving O, and receiving the O OT

.

Among them, OP can be effective or capable. Among them, what will be OP O, and what will be O

OT existing wood, no longer here.

In addition, steps 101 to 106 are operations that can be performed on C on OT.

Step 107: Receive OT, and parse out the received OT.

.

Step 108: Receive the parsed O, and parse the OP in the received O.

In the OT, the O is analyzed, and the OP is extracted from the existing wood. Step 109, receiving the parsed OP, 0 of 0 in the OP is 0, if yes, then the OP is complete, and then performing step 110 otherwise, the OP force is valid, and then step 5 is performed, step 110, all, before Process.

Step 11, the output is valid, and the execution step 112 is performed.

Step 112, receiving valid, will receive a valid C, which will contain 8 of the seven.

Chengli in step 101, combined with 2 fields of wood 0 is easy to understand what the solution, no longer here.

Among them, step 09 to step 2 have the demapping of OP to C. Steps 107 to 112 are operations required to receive the OT exchange for C when the OT is received.

3 force this C OT's indication. 5 Among them, each includes C, , rate, control, O and OT receiving, each including OT, O, and C. Where, rate, and control C are mapped to the OP device

Resolve the device that the OP maps to C.

C The east of each C indicates the same mapping of the device shown in Figure 3.

C each, at C. Among them, the mediation C contains 8 valid and .

, C for each C, C with 5, valid 0 for 0 is valid .

Rate, valid for receipt, valid for all valid not less than

All of the effective less than, control, control, and full.

Which is the god of the rate, indicating the rate

All valid is already less than .

The main function of the rate is to assign the rate of C to P.

Control, as received, to rate control. The main function of the control is to monitor the rate of the rate, the effective amount of the rate is less than, and the control control rate stops to be valid, but all.

The rate is valid or full OP.

The mapping from C to OP is performed.

O, at the receiving rate out of the OP, will receive the OP O.

OT, in receiving O out of O, will receive O OT.

At this point, each completed the C to OT special, you can on the OT C.

The following will receive the OT special for each received.

OT, in the OT received by the OT, the O is parsed in the received OT.

O, in receiving O from the OT, The OP is parsed out in O.

, in the OP received O, the 0 of the received OP 0 is 0, if it is, then OP full, all Otherwise, the OP force is valid, valid. Will only be valid. Hugh, first set, but 0 in the 0 is no or not, if yes, then all else, will.

, valid after receiving, will receive a valid C.

The demapping of OP to C is reconciled. C each, received C.

At this point, C敖 is completed in C.

Compared with the existing wood schemes of the above wood schemes, it can be seen that the existing woods, due to the comparison of the GP itself, need to execute 64b/65b, including management and system, and nearly contain multiple channels, so the GPC OP has the same mapping mapping, occupying resources. Larger and used and rate

It is possible to map from C to OP, and use the solution to demap the OP to C and compare the sheep, so the resources can be occupied.

Let's take a look at the mapping of the 2G C P in the following, so that the field can understand this.

2G CP under the same mapping Step 201, C each 2 C .

Among them, C 9 , contains 8 valid and .

Step 202: Receive 2 C of each C, and receive the received C of the C into a valid of 8 and then valid, 0 1 of the valid 0. 2 and 4 are shown.

In step 203, the rate is valid, and the rate of 2 C is assigned to P. Since the rate of P is faster than the rate of 2G C, there may be a case where the effective number is empty, so the rate needs to fill the same rate of 2G C P with the full packet, the rest force

Whether all the effective quantities are less than, if it is, then to control, control in the receipt, return control, rate control, and to the rate of the target, otherwise effective.

Step 204, O receives the rate of P, and will receive the P, of course.

Step 205, the OT receives the O, and receives the received T, and then receives each T.

Step 206, the OT receives the T of the OT, and parses the received T, and then.

Step 207, O receives the OT out, and parses the received P, and then P.

Step 208, receiving O out of P, 0 of 0 in the received P is 0, if yes, then OP is full, all else, otherwise P force is effective and effective.

Step 209, the valid is received, and the valid C will be received, and Hugh will contain 8 of C 9 C.

Step 210, C each receives C.

In the above, each 2 C maps to P, then T, then T, receives each T

P , then P maps 2 C .

In addition, 1 C P has the same mapping mapping, and 8G C P 2 has the same mapping mapping, and 2G C P has the same mapping mapping, and is no longer here.

Above, the best of the power, not the limit
