# Protocol implementations

lwIP implements a variety of protocols. Support for each protocol can be individually included in or excluded from the configuration, subject to dependency constraints. The protocol implementations are mostly compartmentalised into separate source modules. Support exists for TCP, UDP, IP obviously (and implicitly ICMP), ARP when using Ethernet, DHCP, SLIP and PPP.

In most cases functionality has been intentionally restricted to avoid "bloat" (unnecessary features increasing resource use), or in some cases completely omitted. This is covered in slightly more detail in the Section called Limitations.
