As shown in the table, the data packet for accessing net mainly includes following sections:

DA SA Reserved Payload CRC

Wherein:

Destination address (DA) is made of 8 bytes (byte), and first character section indicates type (such as the various associations of data packet Discuss packet, multicast packet, unicast packet etc.), be up to 256 kinds of possibility, the second byte to the 6th byte is metropolitan area net address, Seven, the 8th bytes are access net address;

Source address (SA) is also to be made of 8 bytes (byte), is defined identical as destination address (DA);

Reserve bytes are made of 2 bytes;

The part payload has different length according to the type of different datagrams, is if it is various protocol packages 64 bytes are 32+1024=1056 bytes if it is single group unicast packets words, are not restricted to above 2 kinds certainly;

The host CPU chip first starts, and after the host CPU chip confirmation local boot is out of question, triggering starting control signal leads to It crosses the interchanger and starting control signal is sent to first cpu chip, for starting first cpu chip; After first cpu chip confirmation local boot is out of question, triggering starting control signal, by the interchanger by the starting Control signal is sent to second cpu chip, for starting second cpu chip;The second cpu chip confirmation is local Start it is out of question after, triggering starting control signal, by the interchanger by the starting control signal be sent to the third Cpu chip, for starting the third cpu chip.
6. according to the method described in claim 5, it is characterized in that, the method also includes:
The starting control signal that the host CPU chip triggers is transmitted to by the interchanger using first network interface, using institute It states first network interface and the received starting control signal of the interchanger is transmitted to first cpu chip, start the first CPU Chip;
The starting control signal that first cpu chip triggers is transmitted to by the interchanger using the first network interface, The received starting control signal of the interchanger is transmitted to by second cpu chip using the first network interface, is started Second cpu chip;
The starting control signal that second cpu chip triggers is transmitted to by the interchanger using the first network interface, The received starting control signal of the interchanger is transmitted to by the third cpu chip using the first network interface, is started The third cpu chip.
7. according to the method described in claim 6, it is characterized in that, the method also includes:
It is sent using the second network interface by the vision signal after coding by the host CPU chip or by the interchanger To server.
8. the method according to the description of claim 7 is characterized in that the method also includes:
The host CPU chip, first will be transmitted separately to by the vision signal of network transmission using second network interface Cpu chip, the second cpu chip and third cpu chip;Using the host CPU chip, the first cpu chip, the second cpu chip and Third cpu chip is decoded output to the vision signal by network transmission;Or, using the host CPU chip, the first CPU Chip, the second cpu chip and third cpu chip will be transmitted separately to first decoding by the vision signal of network transmission Chip, the second decoding chip, third decoding chip and the 4th decoding chip are decoded output.
