5 New IP在现有[IPv4/IPv6](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/log/?h=linux-…
16 New IP支持**可变长多语义地址（最短1字节）**，**可变长定制化报头封装（最短5字节）**，通过精简报文头开销，提升数据传输效率。
18 New IP报头开销，相比IPv4节省25.9%，相比IPv6节省44.9%。
20 New IP载荷传输效率，相比IPv4提高最少1%，相比IPv6提高最少2.33%。
26 | New IP for WiFi | 30+8+5=43 B | (1500-43)/1500=97.13% |
30 New IP内核协议栈架构图如下，用户态应用程序调用Socket API创建New IP socket，采用New IP极简帧头封装进行收发包。
36 New IP内核协议栈主要代码目录结构如下：
40 ├── examples # New IP 用户态样例代码
