lwIP is an implementation of the TCP/IP protocol suite focused on reducing resource usage while still having a full scale TCP/IP. lwIP is suitable for embedded systems with ~10KB of free RAM and ~40KB of code ROM.
lwIP features:
- IPv4, IPv6, ICMP, IGMP, TCP, UDP
- Specialized raw API for
... [More] enhanced performance
- Optional Berkeley-alike socket API
- DHCP (Dynamic Host Configuration Protocol)
- PPP (Point-to-Point Protocol)
- ARP (Address Resolution Protocol) for Ethernet [Less]
The pppd daemon works together with the kernel PPP driver to establish and maintain a PPP link with another system (called the peer) and to negotiate Internet Protocol (IP) addresses for each end of the link.
Pppd can also authenticate the peer and/or supply authentication information to the
... [More] peer. PPP can be used with other network protocols besides IP, but such use is becoming increasingly rare. [Less]
