Network Standards

Aside from the important POSIX standards, GNU/Linux also follows many other standards, notably in the network area, where all major protocols are supported. Supported standards include the hardware standard for Ethernet Token-Ring FDDI, ATM etc., and the protocol layers TCP/IP, UDP/IP, ICMP, IGMP, RAW etc.. This standardization level allows a good judgment of a embedded Linux system at a very early project stage, and at a later stage simplifies system testing a lot.
