distributing any on-demand address of a network to each interface of a group of nodes, and receiving and transmitting data packets by the group of nodes according to the any on-demand address; wherein any on-demand address is an address aggregated using a continuous bit mask,
a group of interfaces belonging to different nodes has an identifier, and packets sent to the arbitrary on-demand address are passed to an interface identified by the identifier and closest to the distance metric according to the routing protocol.
The arbitrary on-demand address has 232 bits and is divided into 7 segments, wherein, the 1 st segment is the 1 st to 8 th bits and represents the type prefix, the 2 nd segment is the 9 nd to 16 th bits and represents the country, the 3 rd segment is the 17 th to 32 th bits and represents the region, the 4 th segment is the 33 th to 40 th bits and represents the top-level operator, the 5 th segment is the 41 th to 56 th bits and represents the operator definition, the 6 th segment is the 57 th to 200 th bits and represents the user ID, and the 7 th segment is the 201 th to 232 th bits and represents the interface address;
when the 8 th bit in the type prefix is 5, the address type is any on-demand address.
The preferred text string canonical address form adopted in this embodiment is as follows, without limitation to other forms:
among the 7 segments forming any on-demand address, the 1 st segment to the 5 th segment and the 7 th segment are decimal values, the 6 th segment is a character string value, each segment is separated by a one-sided brace symbol, for example, any on-demand 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 the address category, i.e. any on-demand address is 5 (00000005 compression or abbreviated recognition mode, vide infra).
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 144-bit address field, which may include numbers and upper and lower case English letters, representing the user ID, which may be an organization, company, natural person, etc. Any on-demand address has an address prefix, the length of which is the decimal value that makes up the address prefix.
g is a decimal value of a 32-bit address field, which may also be identified by a dotted decimal number, representing the user interface address. The user interface address may be an interface address in IPv4 mode.
For example: any on-demand address for a server of a company can be identified as:

any on-demand address/prefix length;
wherein the prefix length is a decimal value that constitutes a prefix identifying the length of the leftmost consecutive address bits of any on-demand address.
For example:
200 length prefix of any on-demand address of a natural person:
5{1{21{2{1000{310107198808031X can be represented in the following format:
5{1{21{2{1000{3101071988080310/200, the entire arbitrary on-demand address can be abbreviated as:
5{1{21{2{1000{3101071988080310{10.0.0.1/200, then, the address range that a natural person possesses is:
5{1{21{2{1000{3101071988080310{1---5{1{21{2{1000 {3101071988080310{4294967294,
the 1 st, 2 nd, 4 th and 6 th section addresses of any on-demand address cannot be divided by masks, and the mask range is as follows:
8
16~32
40~56
200~232。
in assigning any on-demand address, if an address contains a long string of 0 bits, then using "{ }" indicates that there are multiple sets of 0 values. The node receives and transmits the data packet according to any on-demand address of each interface, and the node with the return address is used for sending the data packet to the node. The return address is not assigned to any logistics interface.
For example:
when the 1 st section to the 6 th section in the 7 sections forming the arbitrary on-demand address are 0 and the 7 th section is 1, the arbitrary on-demand 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 forming any on-demand address are all 0, taking the any on-demand address 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 arbitrary on-demand address is used to identify a group of routers belonging to an organization providing network services, and the arbitrary on-demand address is used in a routing header to identify an address.
The arbitrary on-demand address is used to identify a group of routers connected to a particular subnet or to identify a group of routers providing ingress to a particular routing domain.
The arbitrary on-demand address is not used for a source address of the packet, and the arbitrary on-demand address is not assigned to the host and is only assigned to the router.
The router identifies all addresses that the host can identify, and can also identify the following addresses that identify itself:
configuring any on-demand address of a subnet router used by an interface for the router to work;
all other arbitrary on-demand addresses to be used by the router configuration are completed.
Example 2
The embodiment provides an internet, and the internet provided by the embodiment is addressed by the network any on-demand addressing method described in the embodiment one, and transmits a data packet.
The above are merely specific embodiments of the present invention, but the scope of the present invention is not limited thereto. It will be appreciated by those skilled in the art that the present invention includes, but is not limited to, those described in the foregoing detailed description. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
