Description

The implementation method of MoCA multiport terminal management channels

Technical field

The present invention relates to a kind of implementation method of MoCA multiport terminal management channels.

Background technology

EoC technology is former to be to come from some producers of Europe, and original text is " Ethernet over COAX ", a kind of transmission technology of ethernet signal on coaxial cable just, and the frame format of original Ethernet signal does not change.EOC the earliest is actually passive EOC or the base band EOC that hereinafter is said.Present then all technology at the Cable transmitting data all are called EOC.EOC (Ethernet Over COAX) mainly can be divided into baseband transmission, modulation transmissions is used two types; Present most of EOC technology can both provide two-way 100M above bandwidth; The antinoise interference performance can be worked under abominable network environment far above Cable Modem, therefore is widely used.

Along with the extensive use of EOC product, MoCA is used by increasing radio and television users as the middle important technology of EOC product.

This is researched and developed as home networking equipment owing to the MoCA technology, and this application need not through the MoCA head end terminal prot to be managed.After being used for Access Network, the cLINK that derives out is technological, has inherited standard and the correlation technique of MoCA, the same management channels that lacks special use.

Continuous development when the broadcasting and TV Access Network is accompanied by the open-minded of new business, must realize the management to the multiport terminaling exchange, could effective support is multiple services carries out.And the MoCA technology can't send to the terminal to the parameter of telemanagement through head end through management channels, also can't obtain the working condition of each port of terminal, can't adapt to the growth requirement of existing network.

Summary of the invention

Technical problem to be solved by this invention provides a kind of implementation method of MoCA multiport terminal management channels, has realized the simple and effective configuration in terminal.

In order to solve above-mentioned technical problem, technical scheme of the present invention is: a kind of implementation method of MoCA multiport terminal management channels, and it comprises the setting and the two parts that fetch data:

(1) when needs is got the exchanger information at a certain terminal

I) command frame command phase of management packets is set according to the port that will get, and puts into the MAC Address section of management packets to the MAC Address at this terminal, utilize the ICMP router that is integrated in the head end to send ICMP bag data through the update passage;

Ii) the MoCA terminal receives the laggard line command parsing of packet, and the digital data of corresponding port is put into 5 registers of NumOfMapTx;

Iii) the MoCA head end is inquired about above-mentioned 5 registers through api function, obtains the configuration data of corresponding port;

Iv) by that analogy, adopt the method to get the configuration data of other all of the ports;

(2) carry out switch segment to the terminal when being configured when needs

I) port that disposes as required is provided with the command frame command phase of management packets; This moment, the command frame command phase of management packets was set to be different from the command frame command phase that fetches data; Put into the MAC Address at this terminal the MAC Address section of management packets; And put into data segment to the data of corresponding port, and the length of specified data section valid data;

Ii) utilize the ICMP router that is integrated in the head end to send data through the update passage;

Iii) the MoCA terminal receives the laggard line command parsing of packet, obtains the corresponding data of data segment in the management packets, and obtains each configuration parameter configuration switch work by certain format;

Iv) by that analogy, adopt the method that other all of the ports are configured.

Because the MoCA system does not have ready-made management channels; Has only a update passage that is used for upgrading terminals or downloads the MoCA configuration parameter; Use special windows application program; Also send packet by the data segment that certain format is carried to the ICMP packet, and send to each terminal through the data of this passage transmission through the MoCA network, the MoCA head end utilizes the update passage to send to corresponding terminal after receiving this packet; After the MoCA terminal received icmp packet, whether the testing goal MAC Address was this machine address or broadcast address, if then be placed on message the buffering area of master chip and notify main control MCU to obtain message.

Utilize this principle; Integrated ICMP bag router on the MoCA head end; When long-range send to head end to the configuration information of terminaling exchange through modes such as SNMP, Telnet after, head end is carried to the data segment of ICMP bag to these information according to certain form, re-sends to the MoCA terminal; Corresponding order or configuration data are obtained according to this form after receiving message in the MoCA terminal; And put into corresponding data according to order 5 32 vacant bit registers such as NumOfMapTx; Head end obtains the data of these five registers through api function then; And according to the related data in these the several registers of command analysis that send, thereby realize the up-downgoing management channels.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.

Fig. 1 is the flow chart that the present invention gets the terminal configuration parameter;

Fig. 2 is that the present invention realizes the flow chart to the terminal prot configuration;
