在上面的代码示例中,udp_header结构体定义了UDP头部的各个字段,UDP_HEADER_SIZE宏则通过sizeof运算符计算了UDP头部的大小,结果为8个字节。 综上所述,UDP头部的大小是固定的8个字节,不包含任何可选字段或变长部分。

A TCP header size of 20 bytes (160 bit) is the minimum size allowed. 40 bytes can be added to the header with additional options which allows for a maximum header size of 60 bytes (480 bit). A UDP header is smaller at 8 bytes (64 bit). ...

The relatively huge header size of upper layers' protocols (e.g. TCP, UDP and IPv6), in addition to IEEE 802.15.4 header, will deplete the frame payload to approximately 33 bytes. Some schemes had been designed to compress the headers to provide more space for the data payload. In this...
