1. Structure diagram

2. Program function:

The network protocol stack mainly contains the following parts of the protocol support:

• Support for Ethernet
• Support for IP protocols
• Support for ICMP protocol
• Support for UDP protocol
• Support for the protocol abstraction layer
• Support for user interfaces
