ejIP: a TCP/IP stack for embedded Java

Abstract

To enable Java on resource constraint embedded devices, the whole system should be implemented in a single programming language to avoid overheads on language boundaries. However, most of the functionality that is dedicated to the operating system layer is usually written in C. In this paper we present the design and implementation of a network stack written entirely in Java. This implementation serves as an example how to implement system functions in a safe language and gives evidence that Java can be used for operating system related functionality. The described TCP/IP stack ejIP has already been successfully used in industrial projects on pure Java embedded systems.
