Problems solved by technology

[0002] In the initial deployment process of the MAP (Mapping Address and Port) technology in the prior art, the MAP-CE (MAP Customer Edge, MAP Customer Edge) and MAP-BR in the MAP Domain (Mapping Address and Port Domain) are manually (MAP Border Relay, MAP Border Relay) The same MAP domain rules are configured on the two MAP nodes to implement address translation and address encapsulation. Although this manual configuration method can realize the corresponding functions of the MAP nodes in the MAP domain, it is not conducive to The dynamic deployment of MAP nodes, especially when the MAP-CE needs to change the MAP domain (mainly reflected when the MAP-CE needs to change the MAP domain rules), this manual configuration of the MAP domain rules is even more inconvenient. Because most MAP-CEs are deployed in customers' homes, this increases the difficulty of manually configuring MAP domain rules and increases the cost of operation and maintenance.

Embodiment 1

[0054] Embodiment 1 of the present invention provides a method for dynamically issuing MAP domain rules, refer to figure 1 ,include:

[0055] Step 10, configure address pool parameter information according to domain rules so as to obtain corresponding mapping rules; domain rules include BMR rules and DMR rules, etc., wherein, BMR rules include Rule-IPv6-prefix (An IPv6 prefix assigned by a service provider for a mapping rule, Rule IPv6 prefix), Rule-IPv4-prefix (An IPv4 prefix assigned by a service provider for a mapping rule, rule IPv4 prefix), EA-bits-length (Embedded Address (EA) bits length, embedded address (EA) bit length) and PSID-offset (The Port Set Identifier Offset, port set ID offset), DMR rules include BR-address (BorderRelay address, border relay address).

[0056] The configuration of address pool parameter information is as follows, refer to figure 2 :

[0057] (1) Configure the network prefix and the length of the network prefix in the address pool paramet...

Embodiment 2

[0080] On the basis of Embodiment 1, this embodiment also provides a system for dynamically issuing MAP domain rules, including a protocol module, an address pool module, an authentication module, and a dynamic routing module;

[0081] The address pool module is used to obtain an address application request, and allocates a prefix proxy address corresponding to the address application request according to a mapping rule; the protocol module is used to receive the prefix proxy address and address pool parameter information sent by the address pool configuration module, And after calculating the domain rule according to the prefix proxy address and the address pool parameter information, the calculated domain rule is encapsulated into the response message sent to the user.

[0082] The authentication module is used to obtain the authentication domain corresponding to the user according to the authentication authorization request sent by the protocol module, and authenticate the use...

Embodiment 3

[0086] In order to facilitate the understanding of the present invention, on the basis of Embodiment 1 and Embodiment 2, this embodiment also provides a way that can be realized in actual scenarios, such as Image 6 As shown, the OLT (English full name: optical line terminal Chinese full name: optical line terminal) is composed of a protocol module, an address pool module, an authentication module and a dynamic routing module. Image 6 DHCPv6 is the protocol module, AAA is the authentication module, IPPoolv6 is the address pool module, and BGP4+ / OSPFv3 is the dynamic routing module;

[0087] Step 201, user 1 sends a request message to DHCPv6 for obtaining the prefix proxy address, and step 202, after receiving the request message, DHCPv6 parses the request message and confirms that the request message is used to obtain the prefix proxy address , send an authentication authorization request to AAA, and perform AAA authentication. In step 203, AAA obtains the authentication doma...

Abstract

The invention relates to the technical field of development transition from IPv4 to IPv6, in particular to a method and device for dynamically issuing an MAP domain rule. The method comprises the following steps: configuring address pool parameter information according to a domain rule so as to obtain a corresponding mapping rule; collecting an address application request; allocating a prefix proxy address corresponding to the address application request according to a mapping rule; and sending the prefix proxy address and the address pool parameter information to a protocol module, so that the protocol module encapsulates the prefix proxy address and a domain rule calculated according to the address pool parameter information into a response message sent to a user. According to the method and the device, the BMR rule and the DMR rule corresponding to the MAP domain are fused into the service processing flow of the WAN port of the user for requesting to allocate the prefix proxy address, so that the mode of manually configuring the domain rule on the user side in the prior art to realize the MAP technology is effectively replaced, the dynamic switching of the MAP domain of the user is realized, and the operation and maintenance difficulty is reduced.
