从 TCP-IP 详解卷一第 11 章的 udp 数据包的包头可以看出，udp 的最大包长度是 2^16-1 的个字节。 由于 udp 包头占 8 个字节，而在 ip 层进行封装后的 ip 包头占去 20 字节，所以这个是 udp 数据包的最大理论长度是 2^16-1-8-20=65507。 然而这个只是 udp 数据包的最大理论长度。

NDN has a stateful forwarding plane for datagram delivery (per packet and per hop) in comparisons to the IP’s stateless forwarding plane. As a matter of fact, IP forwarding by itself has no ...

As such, a TCP/IP Ethernet frame is an OSI Model Layer 2 PDU. Note that the word datagram is sometimes used interchangeably with PDU or packet in RFCs and commercial documents.
