Abstract

The invention discloses an inform method of access loop package method information, wherein a wideband access device calculates the detail information of access loop package method, inserts the detail information of package method into relative items of a DHCP or PPPoE protocol report, the wideband network gate device receives the DHCP or PPPoE report, to extract the access loop package method information. The invention via inserting access loop package information into PPPoE and DHCP report can inform package information from the wideband access device to wideband network gate device, without additional protocol or report, with simple process.

Description

A kind of access loop packaged type notification of information method

Technical field

The present invention relates to broadband access technology, relate in particular to a kind of access loop packaged type notification of information method between broad access network gate and the broadband access equipment.

Background technology

Broadband access technology has obtained extensive use now, but for the broadband network that adopts DHCP protocol core PPPoE agreement, between broadband access equipment nuclear broad access network gate, transmit bulk information, need encapsulate transmitting the specifying information that inserts loop, and for inserting loop packaged type information, then need be notified to broad access network gate, the information of being transmitted be carried out respective handling according to packaged type information by broadband access equipment.

Specifically, the needs for inserting loop packaged type information mainly are based on following several aspect:

1) demand of broad access network gate equipment shaping feature

Because broad access network gate is the IP fringe node, need accurately know encapsulation overhead on broadband access equipment (as DSLAM) the ATM layer and carry out traffic shaping function accurately, as ATM segmentation, Ethernet LLC/SNAP encapsulation or the like.

2) demand of network management

Generally, broadband access equipment and wideband network gateway equipment all have independently management system, need show the protocol stack that inserts loop on wideband network gateway, reduce the O﹠M expense.

3) demand of aaa authentication/tactical management

Broad access network gate can be further transmits the line related packaging information to strategic server, so that the foundation of more carrying out policy development to be provided, and to be convenient to fault and to trace to the source and diagnose, solve.

Therefore, need a kind of access loop packaged type notification of information method of simple and easy to do, highly effective and safe, so that achieve a butt joint into the transmission of the concrete packaging information of loop.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of access loop packaged type notification of information method, in order in broadband access system, inserts loop packaged type information by broadband access equipment to the transmission of wideband network gateway equipment.

The invention provides a kind of access loop packaged type notification of information method, be used at the broadband access system that comprises client terminal, broadband access equipment, wideband network gateway equipment, packaged type information is notified to wideband network gateway equipment by broadband access equipment, comprises the steps:

(1) determines to comprise at least in the wideband protocol message that client terminal sends the relevant option of packaged type information;

(2) broadband access equipment calculates the specifying information that inserts the loop packaged type;

(3) the broadband access equipment specifying information that will insert the loop packaged type in the wideband protocol message is inserted into the relevant option of packaged type information;

(4) wideband network gateway equipment extracts relevant access loop packaged type information from the protocol massages of broadband.

Wherein, described wideband protocol message is the DHCP request message for the DHCP agreement, is that PPPoE finds message for the PPPoE agreement.

The present invention is by insert inserting loop packaged type information in PPPoE and DHCP message, realized packaged type information is notified to the process of wideband network gateway equipment by broadband access equipment, do not need additional protocol or message, and is simple and convenient.

Description of drawings

Fig. 2 transmits under the DHCP scene to insert loop packaged type information schematic diagram;

Fig. 3 transmits under the PPPoE scene to insert loop packaged type information schematic diagram.

Embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

Access loop packaged type notification of information method of the present invention mainly comprises following step:

At first, need be in the wideband protocol message that client terminal sends, the option information that is defined as follows:

Physical layer type (PHY TYPE) can comprise ADSL, VDSL, ADSL2 and other physical layer type, as APON, GPON etc.;

The link layer type is as ATM and Ethernet;

The specifying information of encapsulation is as the expense of cell size, every cell, frame overhead etc.

In this step, broadband access equipment calculates the specifying information in the packaged type information, for example various information such as cell tax, frame overhead.

Broadband access node device (for example DSLAM) is found in the message the concrete packaged type information (see figure 1) that inserts loop to be inserted relevant option at DHCP request message or PPPoE.

(4) wideband network gateway equipment extracts relevant access loop packaged type information from broadband protocol massages (DHCP request message or PPPoE find message).

Wideband network gateway (or BAS Broadband Access Server) extracts relevant access loop packaging information from the DHCP message that receives or PPPoE; These line informations are as the foundation of traffic shaping or the like function decision-making.

When the present invention specifically implements, adopt coded format as shown in the table, insert encapsulation specifying information shown in Figure 1.

Option number

The message length that nybble is represented (Length)

The value of information with the statement of 32 bit forms

As shown in Figure 2, be to transmit the schematic diagram that inserts loop packaged type information under the DHCP scene.After determining choice format, and after having determined to insert the specifying information of loop packaged type, the relevant option of broadband access equipment in the DHCP request message inserts the encapsulation specifying information, and wideband network gateway therefrom extracts the loop packaged type information that inserts after receiving the DHCP request message.These line informations are as the foundation of traffic shaping, network management or the like function.

As shown in Figure 3, be to transmit the schematic diagram that inserts loop packaged type information under the PPPoE scene.After determining choice format, and after having determined to insert the specifying information of loop packaged type, broadband access equipment finds that at PPPoE the relevant option in the message inserts the encapsulation specifying information, and BAS Broadband Access Server therefrom extracts the loop packaged type information that inserts after receiving the PPPoE message.These line informations are as the foundation of traffic shaping, network management or the like function.
