Description
Technical field
The present invention relates to network communication technology field, be specifically related to a kind of IPV6 based on DCC agreement ground
Location coding, coding/decoding method and the system of correspondence thereof.
Background technology
From the point of view of in terms of technical development of computer, internet rule and network transmission speed etc., existing
IPV4 is the most inapplicable.It is empty that the most topmost problem is exactly the IP address of 32 bits of IPV4
Between cannot meet the Internet-scale of rapidly expansion.Therefore, IPV6 agreement in telecommunications core network and
Application in terminal there will be and get more and more.
IPv6 address is 128 bit lengths, generally writing 8 groups, and often group is the form of four hexadecimal numbers.
Such as: FE80:0000:0000:0000:AAAA:0000:00C2:0002 is a legal IPv6 ground
Location.IPv6 address can carry out the reduction of length by zero compression method.
The implication of zero compression method is: if the value of several continuous sections is all 0 in address, then these are 0 years old
Just can simply with:: represent.So address above mentioned just can be write as
The simplified way of FE80::AAAA:0000:00C2:0002.But zero compression method in the address can only be with once.
It addition, address leading zero can also be omitted in each section, then be after again simplifying
FE80::AAAA:0:C2:2 form.
In the coding/decoding system of DCC agreement, the data type that IP address uses is Address.It is with one
Based on individual variable length string, the first two byte is ddressType, starts to represent from the 3rd byte
Address, each byte value represents 8 bit lengths of IP address.So, IPV6 address just uses 16 words
Joint represents.
At present, IPV6 address also cannot be processed by the coding/decoding system of DCC agreement.But along with telecommunications
The development of core net, necessarily uses IPV6 address, thus requires that coding/decoding system supports this type of as early as possible

Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
Embodiment one, a kind of IPV6 address coding method based on DCC agreement.Below in conjunction with Fig. 1 pair
The coding method that the present embodiment provides illustrates.
Seeing Fig. 1, the coding method that the present embodiment provides includes: S1a, is carried in DCC agreement and joins
The configuration file of each AVP attribute put.
S2a, the coding function corresponding to the AVP configuration with IPV6 address characteristic in configuration file
And decoding functions.
S3a, loaded original DCC message by api interface, and resolve successively in described DCC message
Each AVP.
S4a, each AVP parsed from DCC message extract there is IPV6 address characteristic
AVP, and find coding function corresponding to this AVP.
S5a, call coding function corresponding to each AVP, the IPV6 address in original DCC message is entered
Row coded treatment, forms the DCC message stream output after coding.
Concrete, the config.xml configuration file of each AVP attribute of configuration in DCC agreement is loaded
In internal memory, wherein, AVP be generally of IPV4 address characteristic or IPV6 address characteristic or other
Address characteristic.For configuration file has the AVP of IPV6 address characteristic, configure this AVP corresponding
Coding function and decoding functions, wherein, address corresponding an AVP, an AVP configure it
Corresponding coding function and decoding functions.
Original DCC message is loaded in internal memory by api interface, resolves original DCC successively and disappear
Each AVP in breath, and each AVP kind analytically gone out extracts the AVP with IPV6 address characteristic,
And the coding function corresponding for AVP with IPV6 address characteristic is found according to aforesaid configuration.Respectively
Call coding function corresponding to each AVP, the corresponding IPV6 address in original DCC message is compiled
Code processes.Concrete coding process is: 128 to the IPV6 address in original DCC message
Position, carries out segmentation according to every 8 bytes, altogether obtains 16 bytes；Each to after segmentation
Individual byte makees hexadecimal to metric conversion, has hexadecimal to be converted to ten each byte and enters
System, i.e. each byte is the numerical value between 0 to 255, obtains the IPV6 of metric 16 bytes
Address；From the beginning of the 3rd byte of the IPV6 address of metric 16 bytes after conversion, will be every
One decimal system byte is filled up in the byte of Address categorical variable.Every in original DCC message
After one IPV6 address has carried out coded treatment, by api interface, by the IPV6 address after coding
It is saved in DCC message stream, exports with the form of DCC message stream and use to external equipment.

Breath stream, and resolve each AVP in this DCC message stream.
S2b, each AVP analytically gone out extract the AVP with IPV6 address characteristic, and searches
To the decoding functions that this AVP is corresponding.
S3b, call correspondence decoding functions, to coding after DCC message stream in IPV6 address enter
Row decoding process, obtains decoded IPV6 value.
Wherein, call the decoding functions of correspondence, the IPV6 address in the DCC message stream after coding is entered
The detailed process of row decoding is: enter 16 ten of the IPV6 address in the DCC message stream after coding
Byte processed, from the beginning of the 3rd byte, is converted into hexadecimal byte by each decimal system byte successively,
And with the first blank character segmentation set between each two byte, form the hexadecimal of 8 sections
IPV6 address；Hexadecimal IPV6 address character string to described 8 sections, starts anew to search,
If the string value that there is continuous section is 0, then the character string of this continuous section is used the set
Two blank characters, replace, and form the IPV6 address character string after zero compression processes；Zero compression is processed
After IPV6 character string, start anew search, if the beginning of each section is 0 or 00 or 000, then
Dispense 0 or 00 or the 000 of beginning, formed and omit the IPV6 address character string after leading zero processes.
Wherein, the object lesson that zero compression processes and omission leading zero processes is: such as, obtain
The hexadecimal IPV6 address character string of 8 sections be
FE80:0000:0000:0000:AAAA:0000:00C2:0002 is a legal IPV6 address, IPV6 ground
Location can use zero compression method and omission leading zero compression method to carry out compresses in length.The implication of zero compression method
For: if the value of several continuous sections is all 0 in IPV6 address, then these 0 just can simply with::
Represent.The simplification of FE80::AAAA:0000:00C2:0002 just can be write as in the most above-mentioned IPV6 address
Mode, but zero compression method can only be with once in IPV6 address.It addition, each section in IPV6 address
In leading zero can also omit, then be FE80::AAAA:0:C2:2 form after again simplifying.
See Fig. 3, above-mentioned IPV6 geocoding based on DCC agreement and coding/decoding method are combined
Illustrate.First read configuration file, and be loaded into internal memory, then, read original DCC
Message is also loaded into internal memory.Judge to need coded treatment to need for decoding during this original DCC message
Process, when original DCC message needs coded treatment, resolve the AVP in DCC message, find
The coding function mated with this AVP, uses coding function to encode IPV6 address.Concrete volume
Code process is: intercept the step-by-step of initial IP V6 address, and every 8 intercept once, obtain 16 bytes,
Each byte is carried out hexadecimal to metric conversion, from the beginning of the 3rd byte, by each ten
The byte of system is filled up in the corresponding byte of Address categorical variable.IPV6 after coding is passed through address
Api interface is saved in DCC message stream.When original DCC message needs decoding process, resolve
Each AVP in DCC message, finds the decoding functions that this AVP mates, and uses decoding functions to IPV6
Address is decoded.Concrete decoding process is: read the IPV6 address after coding, by byte cycle,
The decimal system in byte is converted to hexadecimal, and each two byte is split with separator ": ",
And the IPV6 address after segmentation is carried out zero compression method process and omits leading zero process, after being decoded
IPV6 address, and exported by api interface.
