1INTRODUCTION
2
3lwIP is a small independent implementation of the TCP/IP protocol suite.
4
5The focus of the lwIP TCP/IP implementation is to reduce the RAM usage
6while still having a full scale TCP. This making lwIP suitable for use
7in embedded systems with tens of kilobytes of free RAM and room for
8around 40 kilobytes of code ROM.
9
10lwIP was originally developed by Adam Dunkels at the Computer and Networks
11Architectures (CNA) lab at the Swedish Institute of Computer Science (SICS)
12and is now developed and maintained by a worldwide network of developers.
13
14FEATURES
15
16  * IP (Internet Protocol, IPv4 and IPv6) including packet forwarding over
17    multiple network interfaces
18  * ICMP (Internet Control Message Protocol) for network maintenance and debugging
19  * IGMP (Internet Group Management Protocol) for multicast traffic management
20  * MLD (Multicast listener discovery for IPv6). Aims to be compliant with
21    RFC 2710. No support for MLDv2
22  * ND (Neighbor discovery and stateless address autoconfiguration for IPv6).
23    Aims to be compliant with RFC 4861 (Neighbor discovery) and RFC 4862
24    (Address autoconfiguration)
25  * DHCP, AutoIP/APIPA (Zeroconf) and (stateless) DHCPv6
26  * UDP (User Datagram Protocol) including experimental UDP-lite extensions
27  * TCP (Transmission Control Protocol) with congestion control, RTT estimation
28    fast recovery/fast retransmit and sending SACKs
29  * raw/native API for enhanced performance
30  * Optional Berkeley-like socket API
31  * TLS: optional layered TCP ("altcp") for nearly transparent TLS for any
32    TCP-based protocol (ported to mbedTLS) (see changelog for more info)
33  * PPPoS and PPPoE (Point-to-point protocol over Serial/Ethernet)
34  * DNS (Domain name resolver incl. mDNS)
35  * 6LoWPAN (via IEEE 802.15.4, BLE or ZEP)
36

38APPLICATIONS
39
40  * HTTP server with SSI and CGI (HTTPS via altcp)
41  * SNMPv2c agent with MIB compiler (Simple Network Management Protocol), v3 via altcp
