Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for redistributing address prefixes.
Background
Since the Address allocation of IPv6 network is different from that of IPv4 network, a Broadband Network Access Server (BNAS) of a telecom operator typically maintains two Address pools, one of which is an identity association (IANA) Address pool of Non-temporary addresses, for providing network-side addresses for network edge devices. Second, an Identity Association (IAPD) address pool of prefix authorization is used to provide the user side address for the network edge device.
Generally, after obtaining an IAPD address prefix, a network edge device is configured to assign a network address of a version 6 network protocol (IPv6) to a subscriber access terminal, such as a PC, a PAD, a mobile phone, or the like, thereby performing IPv6 network communication.
However, if a fixed-network broadband home user wants to extend a three-layer network in an IPv6 network, that is, if a network edge device is connected with a network device, the home three-layer network is extended by taking home IPv6 network access as an example, and if a home routing device is connected in series under the home gateway device, the home gateway device does not support distribution of IPAD as an IPv6 network edge device, which may cause a user access terminal connected to the home router device to be unable to obtain an IPv6 address, and further unable to perform IPv6 communication.

The embodiment of the application provides a re-distribution method of an address prefix, which is applied to an IAPD distribution device in an IPv6 network with an expanded three-layer network.
The distribution device can be integrated in the network edge device or can be independently deployed.
When the network edge device is independently deployed, the IPv6 address can be acquired from the network edge device, the IPv6 address can also be acquired from the BNAS, information can be exchanged with the network edge device, the network architecture is not changed, the function of address prefix distribution can be directly realized on the distribution device, and the network edge device realizes functions other than address prefix distribution.
The distribution device is integrated and deployed in the network edge device, and can directly acquire an IPv6 address from the network edge device and also can acquire an IPv6 address from BNAS, the distribution device realizes the function of address prefix distribution, and the network device realizes the functions except for address prefix distribution.
The IAPD distribution device not only connects the user access terminals, but also connects the network equipment, the network equipment connects the user access terminals, namely some user access terminals directly obtain the IPv6 address through the IPAD distribution device to carry out IPv6 communication, and some user access terminals obtain the IPv6 address through the network equipment to carry out IPv6 communication.
Referring to fig. 1, fig. 1 is a schematic diagram of an address prefix redistribution system in the embodiment of the present application. The IAPD distribution mechanism in fig. 1 is exemplified as integrated in an IPv6 network edge device. The IPv6 network edge device receives two network devices and a user access terminal 3, which are network device 1 and network device 2, respectively, network device 1 receives user access terminal 1, and network device 2 receives user access terminal 2.
Fig. 1 is only an example of a networking, and in particular, the implementation is not limited to the number of the network devices connected to the network and the number of the user access terminals.
The IPv6 address acquired by the distribution apparatus includes: IAPD address prefix and IANA address prefix;
and aiming at the IANA address prefix, generating a network side address for providing the network side address for the edge equipment. The IANA address processing is not improved by the application aiming at the prior realization.
The following describes in detail a redistribution process for an IAPD address prefix in the embodiment of the present application with reference to the drawings.
Referring to fig. 2, fig. 2 is a schematic diagram of a redistribution process of address prefixes in the embodiment of the present application. The method comprises the following specific steps:
When acquiring the IPv6 address directly from the BNAS, the IPv6 address may be acquired based on PPPoE and DHCPv6 protocols, including an IANA address prefix and an IAPD address prefix.
The specific acquisition mode is as follows:
PPPoE protocol based authentication, after authentication is successful, DHCPv6 protocol is used for requesting IANA and IAPD two groups of IPv6 addresses;
and when the IPv6 address responded by the BNAS is received, acquiring the IPv6 address.
The IANA address prefix in the IPv6 address is generated into a network side address, and the IAPD address prefix in the IPv6 address is processed in step 202.
When the IAPD address prefix allocated by the BNAS is an IAPD address prefix of an M-bit mask and the distribution granularity is configured to be N, where M, N is an integer and M is smaller than N, in this step, the obtained IAPD address is calculated, and an extended IAPD address prefix and an IAPD address pool are generated, including:
firstly, expanding an IAPD address prefix of an M-bit mask distributed by the BNAS into an IAPD address prefix of an N-bit mask in a 0 supplementing mode, wherein the IAPD address prefix is used as the expanded IAPD address prefix;
when M is 60 and N is 64, the 60-bit mask address prefix "/60" is obtained, and after 0 complementing calculation is carried out, a 64-bit mask address prefix "/64" is generated;
when M is 56 and N is 64, the address prefix "/56" of the 56-bit mask is acquired, and after 0 complement calculation, the 64-bit mask address prefix "/64" is generated.
I.e. the number of bits of the mask is increased, the specific value of the increased number of bits can be determined according to the actual application.
Then, the N-th position 1 of the N-bit mask of the IAPD address prefix of the N-bit mask is used as the minimum address prefix in the address pool, and the last N-M position of the N-bit mask of the IAPD address prefix of the N-bit mask is used as the maximum address prefix in the address pool, so that the IAPD address pool is generated.
When M is 60 and N is 64, taking the 64 th position 1 in the 64-bit mask as the minimum address prefix in the address pool, and taking the last 64-60-4 bits in the 64-bit mask as the maximum address prefix to generate an IAPD address pool;
and when M is 56 and N is 64, taking the 64 th position 1 in the 64-bit mask as the minimum address prefix in the address pool, and taking the last 64-56-8 positions in the 64-bit mask as the maximum address prefix to generate the IAPD address pool.
The specific implementation is to use which address prefix in the IAPD address pool to respond, and the implementation can be implemented according to the configuration rule, which is not limited in the embodiment of the present application.
The step 203 and the step 204 are realized in no sequence, and the corresponding operation is carried out according to the time of receiving the request.
The embodiment of the application further comprises the following steps:
and when receiving an IANA request of a user access terminal, responding the extended IAPD address prefix to the user access terminal.
The user access terminal here is a user access terminal directly connected to the distribution apparatus.
In the embodiment of the application, the extended IAPD address prefix and the IAPD address pool are generated by calculating the IAPD address prefix allocated to the BNAS, and are used for performing IPv6 address response on the network device or the user equipment. The method can effectively solve the problem of acquiring the IPv6 address in the IPv6 network of the expanded three-layer network; and further solve the IPv6 network communication problem in the IPv6 network of the extension three-layer network.
In the following, a home network is taken as an example with reference to the specific example.
Referring to fig. 3, fig. 3 is a schematic diagram of an address prefix distribution system applied to a home network. The distribution apparatus in fig. 3 is deployed in a home gateway, and the home gateway is a network edge device in an IPv6 network.
The home gateway is connected with the home router 1, the home router 2 and the mobile phone terminal, the home router 1 is connected with the PC1, and the home router 2 is connected with the PC 2.
And (3) the network side of the home gateway is connected with BNAS, and after PPPoE authentication, the network side requests an IANA address and an IAPD address prefix through DHCPv 6.
In this embodiment, taking M as 60 and N as 64 as an example, the obtained IADP address prefix: using the 16-ary notation: "2010: 1:1:10:: 60";
using a 2-ary notation as: "0010000000010000: 0000000000000001: 0000000000000001: 0000000000010000:: /60".
Firstly, the home gateway is distributed to expand the 60-bit mask IAPD address prefix distributed by the BNAS into a 64-bit mask IAPD address prefix by 0 complementing, and the expanded IAPD address prefix is used.
Generating an extended IAPD address prefix, that is, the IAPD address prefix with a mask of 64 is:
using the 16-ary notation: "2010: 1:1:10: 64";
using a 2-ary notation as: "0010000000010000: 0000000000000001: 0000000000000001: 0000000000010000: : /64".
Then, the home gateway generates an IAPD address pool by using the 64 th position 1 in the 64-bit mask of the 64-bit masked IAPD address prefix as the minimum address prefix in the address pool, and using the 4 th position all positions 1 in the 64-bit mask of the 64-bit masked IAPD address prefix as the maximum address prefix in the address pool.
Using 16-ary to represent address prefixes in IAPD address pools as: minimum address prefix: "2010: 1:1:11: 64"; maximum address prefix: "2010: 1:1:1F:: 64";
using a 2-ary notation as: minimum address prefix: "0010000000010000: 0000000000000001: 0000000000000001: 0000000000010001:: 64 "; maximum address prefix: "0010000000010000: 0000000000000001: 0000000000000001: 0000000000011111: : /64".
When receiving a home router 1 request IANA, distributing and responding to the home router by using an extended IAPD address prefix of '2010: 1:1:10:: 64';
when receiving the IANA request of the home router 2, distributing and responding to the home router by using the expanded IAPD address prefix of '2010: 1:1:10:: 64';
when receiving the request IANA of the mobile phone terminal, the IAPD address prefix '2010: 1:1:10:: 64' can be distributed and responded to the mobile phone terminal.
Upon receiving the home router 1 request IAPD, the IAPD address prefix "2010: 1:1:11:: 64" may be assigned and responded to the home router 1;
upon receiving the home router 2 request IAPD, the IAPD address prefix "2010: 1:1:12:: 64" may be allocated and responded to the home router 2;
the distributed IAPD address prefix "2010: 1:1: 11:/64" can be assigned and responded to the PC1 when the home router 1 receives the IANA requested by the PC 1.
The distributed IAPD address prefix "2010: 1:1: 12:/64" can be assigned and responded to the PC2 when the home router 2 receives the IANA requested by the PC 2.
As can be seen, the mask granularity of the IAPD address pool configuration of the current IAPD distribution apparatus is N ═ 64 bits.
In the embodiment of the application, the problem that downstream network equipment cannot acquire the address prefix of the IAPD can be effectively solved by redistributing the IAPD address allocated by the telecom operation enterprise. Meanwhile, the IPv6 network address can be more effectively utilized.
