Problems solved by technology

The business single disk in the plug-in MSAN device generally only has Layer 2 functions and does not support the routing function. If it needs to support the routing function, the hardware cost and software complexity of the business single disk will be increased.

Embodiment 1

[0046] Embodiment 1 of the present invention provides a system for realizing IPOA by a plug-in MSAN device. The system includes a broadband remote access server BRAS gateway and a plug-in type integrated service access network MSAN device. Refer to figure 1 As shown, the networking of plug-in MSAN devices includes:

[0047] BRAS Server: BRAS gateway server, responsible for IPOA user authentication and protocol processing;

[0048] NMS (Network Management System, network management system): MSAN equipment network management server, responsible for MSAN equipment configuration management.

[0049] MSAN: plug-in DSL central office equipment.

[0050] Modem (modem): DSL client equipment.

[0051] PC: User's home computer.

[0052] The operator configures the IP address of the BRAS gateway to the plug-in MSAN device. The plug-in MSAN device adopts the main control board proxy mode. The main control board obtains the IP address of the BRAS gateway. , address resolution protocol)...

Embodiment 2

[0055] Embodiment 2 of the present invention provides a method for implementing IPOA of a plug-in MSAN device, including the following steps:

[0056] The operator configures the IP address of the BRAS gateway of the broadband remote access server to the plug-in integrated service access network MSAN device. The plug-in MSAN device adopts the master control panel proxy mode, and the master control As an IP agent, the disk initiates an address resolution protocol ARP request to obtain the MAC address of the BRAS gateway. The main control disk maintains the ARP table of the BRAS gateway, and sends the obtained MAC address and IP address of the BRAS gateway to all XDSL service single disks;

[0057] The operator configures the IP address and MAC address for each user on the plug-in MSAN device. When the user accesses the Internet, it sends an IPOA request message. IPOA refers to the transmission of IP data packets on the ATM LAN; the upstream BRAS gateway receives the IPOA request...

Embodiment 3

[0061] On the basis of embodiment 1 or 2, the process of obtaining the MAC address of the BRAS gateway is:

[0062] The main control panel of the plug-in MSAN device sends an ARP request to the BRAS gateway as an agent. After receiving the ARP request, the BRAS gateway responds to the ARP request from the main control panel of the plug-in MSAN device and issues the MAC address of the BRAS gateway. The main control panel obtains the MAC address of the BRAS gateway.

Abstract

The invention discloses a system and a method for realizing IPOA by a plug-in card type MSAN device, and relates to the field of plug-in card type MSAN devices. The method comprises the following steps: the operator configures the IP address of the BRAS gateway to the plug-in MSAN device, and the device adopts the main control disk proxy mode to obtain the IP address of the BRAS gateway, and the main control disk acts as an IP agent to initiate an ARP request to obtain The MAC address of the BRAS gateway, sends the MAC address and IP address of the BRAS gateway to all XDSL service single disks; when the user accesses the Internet, it sends an IPOA request message, and the BRAS gateway receives the message, extracts the user's IP address, and sends it to the user ARP request; the main control panel uses the IP address and MAC address assigned by the operator to respond as a proxy, and the BRAS gateway obtains the user's MAC address and IP address. The invention combines the XDSL service single disk and the main control disk of the plug-in type MSAN equipment to jointly realize the IPOA function.

Description

technical field [0001] The present invention relates to the field of plug-in MSAN equipment, in particular to a system and method for implementing IPOA by plug-in MSAN equipment. Background technique [0002] In the MSAN (Multi-Service Access Network, integrated service access network) communication equipment, the central office equipment is generally responsible for the DSL copper service access through the XDSL service single disk, and the main control disk is responsible for the aggregation and forwarding of the data of each single disk. XDSL is a general term for various types of DSL (Digital Subscribe Line, Digital Subscriber Line), including ADSL (Asymmetric Digital Subscriber Line, Asymmetric Digital Subscriber Line), RADSL (Rate-Adaptive Digital Subscribe Line, rate-adaptive Digital Subscriber Line), VDSL ( Very-high-speed Digital Subscriber Line, SDSL (Symmetric Subscribe Line, Symmetrical Digital Subscriber Line), IDSL (ISDN DSL: Integrated Service Subscriber Line)...
