If we have to use lwIP in a multithread environment, we should (or HAVE TO) use "upper" API layers (netconn or sockets). It’ll serve a Webserver with continuous data fetch over AJAX and Modbus TCP. c are static, so by using compiler optimizations, the current socket code should effectively be nearly the same as without netconns in between. ) We have one thread waiting for data from a controller, plus an occasional need to notified the controller of and event. lwIP is a popular free TCP/IP stack for many embedded processors. DEVELOPMENT lwIP has grown into an excellent TCP/IP stack for embedded devices, and developers using the stack often submit bug fixes, improvements, and additions to the stack to further increase its usefulness. When using an RTOS, this means only calling the lwIP APIs from a single thread.

Hello, As part of a project on building a network monitoring and management based on SNMP for 6LoWPAN/RPL WSNs, we have developed a light-weight SNMPv1 agent which, according to our knowledge, occupies far less text program memory than the existing implementations. socket- and netconn-API are sequential APIs that require threading (one thread for the application that uses the API, one thread for the stack to handle timers, incoming packets, etc. pl) which will connect to server on my computer. Implementing a network driver as described above assumes that LwIP may free the pbuf, but it does not modify it after link_output has been called. The system is Multithreaded which runs over Linux Sues server in grid configuration with single management, supporting protocols such as: TCP/UDP over IPV4 and IPV6 over LWIP stack, UTP, torrent, uTorrent, HTTP, P2P. I guess if I use LwIP then it would be like standalone operating system and if I go for FreeRTOS then the operating system would be multi-thread. lwip ois a small and open source TCP/IP stack which is widely used.
