NicheLite for LPC by InterNiche is a variant of its NicheLite™ product, a full-featured TCP/IP stack optimized for embedded systems, requiring as little as 12 KB of code. An RFC compliant implementation of the TCP/IP protocol suite, NicheLite for LPC includes ANSI C sources for a comprehensive subset of the TCP/IP family of protocols, a "Mini" Sockets API, and a highly effective system optimization and tuning tool. NicheLite for LPC's IP layer can support one hardware interface and is fully instrumented for MIB-II access by SNMP agents. MIB-II tables include: Interfaces, IP, ICMP, TCP and UDP information.

Packet data, including headers, are in contiguous buffers to simplify memory management and avoid data copies. Macros to protect critical sections of code are used sparingly to improve throughput and reduce memory requirements. The tunable parameters such as MSS (Maximum Segment Size) and the TCP window size can be left to the runtime logic or may be customized for your application.

NicheLite for LPC supports the following protocols:

  • Address Resolution Protocol (ARP)
  • Internet Protocol (IP)
  • Internet Control Message Protocol (ICMP)
  • User Datagram Protocol (UDP)
  • Transmission Control Protocol (TCP)
  • Dynamic Host Configuration Protocol (DHCP) Client
  • Domain Name System (DNS) Client
  • Bootstrap Protocol (BOOTP)
  • Trivial File Transfer Protocol (TFTP)
