Detailed Description
The technical solutions of the embodiments of the present invention are explained and illustrated below, but the following embodiments are only preferred embodiments of the present invention, and not all of them. Based on the embodiments in the embodiment, those skilled in the art can obtain other embodiments without creative efforts, which belong to the protection scope of the present invention.
Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure or characteristic described in connection with the embodiment itself may be included in at least one embodiment of the patent disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.
Example one
A data packet transmission conversion method is characterized in that a node acquires a data packet with a self-defined network address, wherein the network address comprises an interface address, and the interface address carries an IPv6 address identifier; and the sending node acquires the interface address, forwards the data packet according to the interface address information, and if the IPv6 address identifier is detected, executes the subsequent operation of the data packet by adopting the IPv6 protocol parameter corresponding to the destination terminal.
The network address structure is divided into 7 segments, wherein, segment 1 defines type prefix (address category), segment 2 defines country (country code), segment 3 defines region (region code), segment 4 defines operator code, segment 5 defines top level operator (operator code), segment 6 defines user ID, and segment 7 defines user interface address; the network address structure comprises 232 bits, wherein a 1 st field is an 8-bit field, a 2 nd field is an 8-bit field, a 3 rd field is a 16-bit field, a 4 th field is an 8-bit field, a 5 th field is a 16-bit field, a 6 th field is a 48-bit field, and a 7 th field is a 128-bit field.
Then, after the 7 th segment is modified to 128 bits, the conversion of the IPv6 mode can be implemented, that is, the user interface address carries an IPv6 address identifier, the IPv6 address identifier is identified, the network transport address is converted into the IPv6 address, and the data packet is sent to the destination terminal corresponding to the IPv6 address.
Optionally, segment 2 is set to have different values to access different transmission addresses, including corresponding aggregated global anycast address values, corresponding link local anycast address values, corresponding site local anycast address values, corresponding multicast address values, and corresponding aggregatable global anycast address values.
Optionally, among the 7 segments constituting the network address, the 1 st segment to the 5 th segment are decimal values, the 6 th segment is a character string value, and each segment is separated by a one-sided brace symbol.
The preferred text string canonical address form adopted in this embodiment is as follows, without limitation to other forms:
among the 7 segments constituting the network address, the 1 st segment to the 5 th segment are decimal values, the 6 th segment is a character string value, and each segment is separated by a one-sided brace symbol, for example, the network address is: a { b { c { d { f { g, wherein:
a is a decimal value of an 8-bit address segment representing a type prefix for identifying an address class.
b is a decimal value of an 8-bit address field representing a country code for being identified as a country, for example a chinese code of 1 may be defined.
c is a decimal value of a 16-bit address field representing a regional code within a country hierarchy for a regional code identified as the country based on identifying the country code, for example, the shanghai code may be defined as 21.
d is a decimal value of an 8-bit address field representing an operator code within a national hierarchy for being identified as a specific operator, e.g., a chinese telecom code of 1, a chinese unicom code of 3, etc.
e is a decimal value of a 16-bit address field representing an operator definition for operator-defined encoding.
f is a string value of a 48-bit address field, which may include numbers and upper and lower case english letters, representing a user ID, which may be an organization, company, natural person, etc. The network address has an address prefix, the length of which is the decimal value that makes up the address prefix.
g is the hexadecimal of a 128-bit address field, which may also be identified by a hyphen hexadecimal to represent the user interface address. The user interface address may be an interface address in IPv6 mode.
Optionally, in the 7 th segment, the user interface address segment adopts a hexadecimal value of IPv6 or a top-off hexadecimal value.
For example: the network address of a server of a company may be identified as:
1{1{21{1{1000{310107{2000：：1。
when the 8 th bit in the type prefix is 1 and the address type is an aggregatable global unicast address, the 2 nd section forming the unicast address is used for distinguishing and aggregating different country regions, and the 3 rd section forming the unicast address is used for aggregating management regions of a single country;
when the 8 th bit in the type prefix is 2, the address type is a link local unicast address, when the address type is the link local unicast address, the 2 nd to 5 th sections of the unicast address are 0, the 6 th section only uses the last 32 bits, and the other bits of the 6 th section are 0; all interfaces need to have at least one link local unicast address.
When the 8 th bit in the type prefix is 3, the address type is a site local unicast address. When the address type is a site local unicast address, all of the 2 nd to 6 th sections of the unicast address are customized.
When the 8 th bit in the type prefix is 4, the address type is a multicast address.
When bit 8 in the type prefix is 5, the address type is an aggregatable global anycast address.
The unicast address assigned to each interface has an interface identifier, and when the address type is a link local unicast address or a site local unicast address, the interface identifier is 32 bits in the last 32 th and 7 th sections of the 6 th section of the unicast address, constituting an IEEE EUI-64 format, and when the u position of the IEEE EUI-64 is 0, the interface identifier has a meaning of a local scope, and when the u position of the IEEE EUI-64 is 1, the interface identifier has a meaning of a global scope. The motivation for using the u-position when forming interface identifiers is to facilitate the system administrator to manually configure a locally scoped interface identifier when a hardware token is not available, i.e., in the case of a serial link, tunnel endpoint, etc. The interface identifier should be unique on its link, possibly to a wide extent, and in many cases one interface identifier is the same as the link layer address of its interface, the same interface identifier may be used on multiple interfaces on a single node, the global uniqueness of the interface identifier is not affected by the same interface identifier on multiple interfaces of a single node, or the global uniqueness of each unicast address is created by the interface identifier.
The network address has an address prefix, the length of which is the decimal value that makes up the address prefix. This embodiment also discloses a representation manner of the address prefix of the network address:
address/prefix length;
wherein the prefix length is a decimal value that constitutes a prefix identifying a length of leftmost consecutive address bits of the network address.
For example:
200 length prefix of somebody's unicast address:
1{1{21{1{1000{310107 can be represented in the following format:
1{1{21{1{1000{310107/200, the entire network address may be abbreviated as:
1{1{21{1{1000{310107{2000：：1/200。
in assigning network addresses, if an address contains a long string of 0 bits, then using "{ }" indicates that there are multiple sets of 0 values. The nodes receive and transmit data packets according to the network addresses of the interfaces, and the nodes with the return addresses are used for sending the data packets to the nodes. The return address is not assigned to any logistics interface.
For example:
when the 1 st segment to the 6 th segment in the 7 segments forming the network address are 0 and the 7 th segment is 1, the network address is used as a return address, and the node with the return address is used for sending a data packet to the node:
0{0{0{0{0{0{1: return address, which may be denoted as {6} 1;
when the 7 segments constituting the network address are all 0, the network address is taken as an unspecified address:
0{0{0{0{0{0{0: the address is not indicated and may be denoted as 7.
Unspecified addresses cannot be allocated to any node, one application of unspecified addresses is to add an unspecified address to the source address field of a transmitted packet at the time of initialization of the host, before the host does not get its own address. Unspecified addresses cannot be used in packets as destination addresses nor in routing headers of the network.

The present embodiments also provide a network packet processing device comprising a receiver, a memory and a processor,
comprises a receiving module used for receiving data packets;
the processor identifies the header information of the data packet, extracts the network address information in the header information, and executes the operation of forwarding the data packet according to whether the network address information carries the IPv6 address identifier.
The above are merely specific embodiments of the present invention, but the scope of the present invention is not limited thereto.
