Abstract

The invention discloses a realization method of a management channel of an MoCA multiport terminal. According to the method, an ICMP packet sending program is integrated on a head end of an MoCA; after configuration information of a terminal switch is sent to the head end in modes like an SNMP and Telnet and the like by a remote mode, the head end bears the information on a data segment of an ICMP packet according to a certain format and then the information is sent to an MoCA terminal; after the MoCA terminal receives a message, a corresponded command or corresponded configuration data are obtained according to the format; and the MoCA terminal put the corresponded data in five spare 32-bit registers like a NumOfMapTx according to the command; and then, the head end obtains data of the five registers through an API function and parses correlated data in the registers according to the sent command, so that uplink and downlink management channels are realized.

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 is to come from some producers of Europe, and original text is " Ethernet over COAX ", the namely a kind of transmission technology of ethernet signal on coaxial cable, and the frame format of original Ethernet signal does not change.EOC is the earliest actually passive EOC or the baseband EOC below said.Present all technology at Cable transmitting data are all called to EOC.EOC (Ethernet Over COAX) mainly can be divided into baseband transmission, modulation transmissions is applied two classes, current most of EOC technology can provide the above bandwidth of two-way 100M, anti-noise jamming ability is far above Cable Modem, can, in severe net environment work, therefore be widely used.

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

Due to MoCA technology, this is researched and developed as home networking equipment, and this is applied without by MoCA head end, terminal prot being managed.After for Access Network, the cLINK technology being derived, has inherited standard and the correlation technique of MoCA, lacks equally special management channels.

When the development of broadcasting and TV Access Network, be accompanied by the open-minded of new business, must realize the management to multiport terminaling exchange, could effectively support multiple services development.And MoCA technology cannot send to terminal by head end the parameter of telemanagement by management channels, also cannot obtain the working condition of the each port of terminal, cannot adapt to the growth requirement of existing network.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of implementation method of MoCA multiport terminal management channels, has realized the simple and effective configuration of 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 setting and the two parts that fetch data:

(1) in the time need to getting the exchanger information of a certain terminal

I) according to the port that will get, the command frame command phase of management packets is set, and the MAC Address of this terminal is put into the MAC Address section of management packets, utilize the ICMP being integrated in head end to send program and by update passage, ICMP bag data are sent;

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

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

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

(2) in the time that needs carry out the switch segment of terminal to be configured

I) port configuring as required arranges the command frame command phase of management packets, now the command frame command phase of management packets is set to be different from the command frame command phase fetching data, the MAC Address of this terminal is put into the MAC Address section of management packets, and the data of corresponding port are put into data segment, and the length of specified data section valid data;

Ii) utilizing the ICMP being integrated in head end to send program sends data by update passage;

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

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

Because MoCA system does not have ready-made management channels, only has one for upgrading terminals or the update passage of download MoCA configuration parameter, use special windows application program, packet is carried to the data segment of ICMP packet and sends by certain format, and the data that send by this passage send to each terminal by MoCA network, MoCA head end utilizes update passage to send to corresponding terminal after receiving this packet; When MoCA terminal receives after icmp packet, whether testing goal MAC Address is the machine address or broadcast address, if so, message is placed on to the buffering area of master chip and notifies main control MCU to obtain message.

Utilize this principle, integrated ICMP bag transmission program on MoCA head end, the configuration information of terminaling exchange is sent to after head end by the mode such as SNMP, Telnet when long-range, head end is carried to these information the data segment of ICMP bag according to certain form, re-send to MoCA terminal; MoCA terminal obtains corresponding order or configuration data according to this form after receiving message, and corresponding data is put into 5 32 vacant bit registers such as NumOfMapTx according to order, then head end obtains the data of these five registers by api function, and according to the related data in these registers of command analysis that send, thereby realize up-downgoing management channels.

Brief description of the drawings

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

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

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

Fig. 3 is the management data packet format of ICMP carrying.

Embodiment

The management channels of the whole MoCA of the present invention is realized having comprised and is arranged and the two parts that fetch data, and distinguishes different instruction by the order in the data segment of carrying.

First in MoCA head end, realize ICMP bag transmission program, and the data of the data segment that is carried to ICMP bag are formulated to a form or agreement, be defined as management packets, as Fig. 3; Data segment in this management packets, then deposit the related data of terminaling exchange with certain form, as the down going channel of management channels.

Due to the up passage fetching data 5 32 vacant bit registers such as be NumOfMapTx, 20 characters altogether, and data on a port of general switch have VLAN ID, priority, upstream bandwidth restriction, downlink bandwidth restriction, port mode, port working state, the functions such as broadcast storm suppresses to enable, the data of four ports are considerably beyond this 20 byte, therefore adopt in the present invention a port to take this 5 registers, and data are deposited into these registers according to certain form, get the order of which port by the command frame command phase placement in management packets and put into corresponding port data.

(1) as shown in Figure 1, in the time need to getting the exchanger information of a certain terminal:

I) command frame command phase of management packets is set to 0x01, and the MAC Address of this terminal is put into the MAC Address section of management packets, utilizes the ICMP being integrated in head end to send program and by update passage, ICMP bag data is sent;

Ii) MoCA terminal receives the laggard line command parsing of packet, finds when command frame command phase is 0x01 the data of switch ports themselves one to put into 5 registers of NumOfMapTx;

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

Iv) then the command frame command phase of management packets is set to 0x02, obtains the configuration data of terminal prot two with identical method, by that analogy, adopt the method to take the configuration data of other all of the ports.

(2) as shown in Figure 2, in the time that needs carry out the switch segment of terminal to be configured:

I) command frame command phase of management packets is set to be different from the order of fetching data, and a port is configured, and data segment is set to 0xa1, and the data of whole port are put into data segment, and the length of specified data section valid data;

Iii) MoCA terminal receives the laggard line command parsing of packet, while finding that command frame command phase is 0xa1, obtains the data of data segment in management packets, and obtains each configuration parameter configuration switch work by certain format;

Iv) in the time of configured port two, the command frame command phase of management packets is set to 0xa2, configures in the same way this port, by that analogy, adopts the method to take the configuration of other all of the ports.
