As shown in Figure 1B, which depict specific solid-state group network process, and each channel is by SID (source FCID)+DID (purpose
FCID)+message ID is formed, and wherein message ID is due to total system unique definition, so the keyword as table.
A record can be preceded by channel table first when creation under each channel, then allocates certain amount in advance to it
DMAbuffer, for send data or receive data.
When the upper layer application on node is wanted to send a block number evidence, calls transmission API, message ID and data can be specified
Content.Communication module can find the matched record of message ID in the local sendaisle list being configured, then
User data carries out tearing frame open, and fills in frame head according to the information in channel (SID+DID+message ID), then be put into DMAbuffer
It sends.
When the communication module of a node receives a frame, SID, DID and message ID can be taken out in frame, then
With carrying out matched and searched in the local receiving channel list being configured.This channel is had found, then the letter for including using channel
Multiple frames are formed complete user data by breath, and notify upper level applications " having data under the channel xxx ".If matching
Failure, then abandon this frame.
Certainly, the meaning in the channel ASM is other than tearing frame framing open, and there are also other functions, such as data redundancy etc., here
It does not detail.
In ASM communication system, each node both defines a sendaisle list and a receiving channel list.Creation

| SID | DID | Message ID |
| 0x10003 | 0x10001 | 8 |
| 0x10002 | 0x10001 | 3 |
The sendaisle of node B is configured with:
| SID | DID | Message ID |
| 0x10002 | 0x10001 | 3 |
| 0x10002 | 0x10003 | 5 |
| 0x10002 | 0x10003 | 6 |
The receiving channel of node B is configured with:
| SID | DID | Message ID |
| 0x10001 | 0x10002 | 1 |
| 0x10001 | 0x10002 | 2 |
| 0x10003 | 0x10002 | 4 |
The sendaisle of node C is configured with:
| SID | DID | Message ID |
| 0x10003 | 0x10001 | 8 |
| 0x10003 | 0x10002 | 4 |
The receiving channel of node C has:
| SID | DID | Message ID |
| 0x10001 | 0x10003 | 7 |
| 0x10002 | 0x10003 | 5 |
| 0x10002 | 0x10003 | 6 |
