# Tap修改的点

## 数据结构的改变

### 1. 设备网络地址信息
```text
message SDLDevAddr {
    uint32 network_id = 1;
    uint32 net_addr = 2;
    uint32 net_bit_len = 3;
    // 增加mac地址信息，6个字节的bytes
    bytes mac = 4;
}
```

### 2. QueryInfo的请求和响应的修改 

```text
message SDLQueryInfo {
    // 改为基于mac地址查询
    bytes dst_mac = 1; 
}

message SDLPeerInfo {
    bytes dst_mac = 1;
    SDLV4Info v4_info = 2;
    optional SDLV6Info v6_info = 3;
}
```

### 3. Data数据消息体

```text
message SDLData {
    uint32 network_id = 1;
    bytes src_mac = 2;
    bytes dst_mac = 3;
    bool is_p2p = 4;
    uint32 ttl = 5;
    bytes data = 6;
}
```

### 4.
```text
message SDLRegister {
    uint32 network_id = 1;
    uint32 src_ip = 2;
    uint32 dst_ip = 3;
}

message SDLRegisterAck {
    uint32 network_id = 1;
    uint32 src_ip = 2;
    uint32 dst_ip = 3;
}

```
