Embodiment 1

[0045] combine Figure 5 As shown in the system unit architecture, the method for directional offloading of carrier-class network address translation on a multi-core processor in this preferred embodiment includes:

[0046] The management unit interacts with the device to complete the device management function.

[0047] The control unit (implementing the function of the determination module 42) completes the authorization of the NAT user and the resource distribution process, and generates a directional distribution table and sends it to the forwarding unit and the processing unit. Image 6 is a schematic structural view of a directional shunt meter according to a preferred embodiment of the present invention, as Image 6 In the directional distribution table shown, IP-id and CPU-id can be used as the above-mentioned directional distribution mark, and the internal number (CPUNo.) of the CPU is determined by combining the IP-id and CPU-id, so that the user's message is sent t...

Embodiment 2

[0054] In this preferred embodiment, a directional shunting method is provided, and the flow process of the method includes the following steps:

[0055] Step 1, configure the address translation service and directional offload flag.

[0056] Step 2, receiving the user message.

[0057] Step 3, determine the user type (for example, IPv4 user, IPv6 user, or dual-stack user, etc.) and perform preliminary processing.

[0058] Step 4, resources (public network address resources) are distributed and services (user packets) are distributed.

[0059] Step five, business processing.

[0060] Step 6, forwarding the message.

[0061] combine Figure 5 As shown in the system unit architecture, in the directional distribution method of this preferred embodiment, step 1 can be completed in the management unit; step 2 can be completed in the forwarding unit; step 3 can be completed in the processing unit to determine different user types, enter Different processing procedures are used ...

Embodiment 3

[0063] Figure 8 It is a schematic diagram of networking taking Ds-Iite as an example according to the third preferred embodiment of the present invention, as Figure 8 As shown, three PCs access the Internet through three CPEs, there are multiple public network addresses on the AFTR device, and the processing unit of the AFTR device has two CPUs. The directional distribution method in this preferred embodiment makes the two PCs obtain different specific Public network address, a PC randomly obtains a public network address.

[0064] An example of configuration in the snap-in is as follows:

[0065]

[0066]

[0067] Configuration example description:

[0068] The processing unit of CGN is divided into several business processing units (SPU), each SPU contains a CPU, and the processing unit can be different boards physically, each board contains several SPUs, and the CGN processing board of a single SPU Simplified case for this example.

[0069] In the aftr mode, first...

Abstract

The invention discloses a method and a device for converting an IP address. The method includes obtaining directional shunt identifications of user messages, wherein the directional shunt identifications are used for confirming a public network address needed to be used by a user; and sending the messages to a processor in a multi-core processor corresponding to the public network address according to the directional shunt identifications to convert the IP address. According to the method and the device, the problem that the user cannot be guaranteed to obtain the special public network address needed to be used in the prior art is solved, and effective supplements are provided for a shunt mode of load sharing in related technologies.

Description

technical field [0001] The present invention relates to the communication field, in particular to an Internet Protocol (Internet Protocol, referred to as IP) address conversion method and device. Background technique [0002] With the popularization and rapid development of network technology, the scale of the network has grown exponentially, and the original Ipv4 addresses have been exhausted, making the deployment of Ipv6 quickly placed in front of operators, for the smooth transition of technology and the cost of operators Considering the considerations, carrier-grade network address translation (Carrier Grade Network Address Translation, referred to as CGN) is regarded as an effective transition technology. The current transition technology is mainly divided into dual-stack (Dual-Stack), tunnel (Tunnel), and translation (Translation). Some tunnel technologies mainly include IPv6 rapid deployment (IPv6 Rapid Deployment on IPv4 Infrastructures, referred to as 6RD) and IPv6...
