Lightweight IP - The Network Protocol Its Features and Applications?

With the advancement in the networking, a communications protocol or network protocol is the specification of a set of rules for a particular type of communication. In modern protocol design, protocols are "layered". Layering is a design principle which divides the protocol design into a number of smaller parts, each of which accomplishes a particular sub-task, and interacts with the other parts of the protocol only in a small number of well-defined ways. The dynamic nature of the Internet and the diversity of its components provide no guarantee that any particular path is actually capable of, or suitable for, performing the data transmission requested, even if the path is available and reliable. In this paper we are covering light weight Internet Protocol (lwIP) which is a widely used open source TCP/IP stack. Further we see the features of the lwIP and its applications. Most of its applications are designed for embedded systems.
