I am working on fpga firmware, in which i want to have very fast data transfer using ethernet . I got help from FPGA forum they say that suggest designs for data transfer using light weight internet protocol (LWIP).
How this is different from transfering the data using NDIS. I will be grateful if you can suggest me some guide to interface my visual c++ application to the network guide and tranfer the data.
many greeting in advance.
LWIP is a library for talking IP on a network. NDIS is a specification for how an OS talks to network cards.
Neither is necessarily what you appear to want.
If you want to transfer data very simply and quickly point-to-point using Ethernet, you need to understand how Ethernet works at the packet level, and form your data into some Ethernet packets. You can make up your own protocol for this if you have control over both ends of the link.
If you want to transfer the data over an existing network topology, you would be better doing it using an existing protocol. UDP/IP might be one such protocol, depending on your requirements for data-rate, latency, software complexity, reliability etc. LWIP is one library which implements UDP, so might be of use.
