example 1

[0062] Example 1: The logical number of the user terminal is 3, and its binary representation is 0000000011, then sid0 is set to 1, sid1 is set to 1, and the others are set to 0;

[0063] Another example is that the logical number of the user terminal is 4, and its binary representation is 0000000100, then sid2 is set to 1, and other sids are set to 0.

[0064] It should be noted that when the DSP digital signal processor receives the Internet access request, it can know the dial-up Internet access method adopted by the user terminal, that is, the DSP digital signal processor can determine whether the user terminal is using ADSL dial-up Internet access or VDSL dial-up Internet access. However, the NPU network chip cannot directly determine the dial-up Internet access mode adopted by the user terminal. Instead, it needs to determine whether the transmitted path information contains vpi / vc field information through the logical id and its mapping relationship, so as to determine t...

example 2

[0067] Example 2: (ADSL dial-up Internet access) receiving the user's operation instruction will be

[0068] port id(1)vpi(8) / vci(35) is mapped to sid(2);

[0069] port id(1)vpi(8) / vci(36) is mapped to sid(3);

 …

[0070] port id(1)vpi(8) / vci(36) is mapped to sid(8).

[0071] In this way, when the DSP digital signal processor determines that the dial-up mode of the user terminal is the ADSL mode, it decodes the path information sent by the ADSL terminal to vpi / vci to map to the first logical id, and then makes the NPU network chip based on the first logical id And obtain the vpi / vci reversely from the first mapping relationship, and determine to work in the ADSL mode.

[0072] Further, it should be noted that the path information transmitted by the user terminals belonging to ADSL dial-up Internet access all have vpi / vci field information, so it is impossible to distinguish whether they are the same ADSL user terminal based on vpi / vci only. Therefore, this embodiment A pa...

example 3

[0074] Example 3: (VDSL dial-up Internet access) receiving the user's operation instruction will

[0075] port id(1) maps to sid(1);

 …

[0076] port id(2) maps to sid(10).

[0077] That is to say, several ADSL user terminals or VDSL user terminals are distinguished by three parameters of physical line portID, vpi and vci.

[0078] Further, the first mapping relationship and the second mapping relationship are stored in the online uplink device.

[0079] Regardless of ADSL or VDSL access, the logical id (ie sid) mapped to it uniquely identifies the user line id (ie user terminal) currently dialing up to access the Internet.

[0080] S20. If it is determined that the dial-up access mode of the user terminal is the ADSL mode, the DSP digital signal processor decodes the virtual path identifier / virtual channel identifier field information in the path information.

[0081]In the embodiment of the present invention, the DSP digital signal processor performs a decoding operatio...

Abstract

The invention discloses a PTM compatible ADSL and VDSL processing method and device, and a medium, and the method comprises the steps: enabling a DSP digital signal processor to obtain an Internet surfing request, and determining a dial-up Internet surfing mode; if it is determined that the dial-up networking mode of the user terminal is ADSL, the DSP decodes virtual path identifier / virtual channel identifier field information; mapping the virtual path identifier / virtual channel identifier field information into a first logic id according to a preset first mapping relationship, and sending thefirst logic id to the NPU network chip; enabling the NPU network chip to reversely acquire the virtual path identifier / virtual channel identifier field information according to a preset first mappingrelationship, and determining that the forwarding mechanism of the data flow is ADSL, thereby completing ADSL mode processing supported in the PTM transmission mode. According to the invention, the DSP can support the ADSL mode and the VDSL mode at the same time in the PTM transmission mode, the transmission mode of the DSP does not need to be switched, and the Internet surfing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of communication networks, in particular to a processing method and equipment for PTM compatibility with ADSL and VDSL. Background technique [0002] Communication network refers to the physical connection of various isolated devices to realize the link of information exchange between people, people and computers, and computers, so as to achieve the purpose of resource sharing and communication. [0003] There are many ways to realize the communication network in the prior art. Usually, the user uses VDSL to access the Internet, and the transmission mode adopted for the communication is the PTM transmission mode. But sometimes according to different network conditions, the same user needs to switch from VDSL to ADSL, but needs to switch the PTM transmission mode to the ATM transmission mode. Therefore, the existing technology cannot support both VDSL and ADSL under the same PTM mode. , it is not convenient ...
