Abstract
High productivity embedded network software is required to run embedded systems within the Internet of Things (IoT). Tomakomai InterNETworking (TINET) is a Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack for use in embedded systems. Although TINET is a compact protocol stack, it comprises many complex source codes and is difficult to maintain, extend, and analyze. To improve scalability and configurability, this paper proposes TINET componentized with the Toyohashi Open Platform for Embedded Real-time Systems (TOPPERS) embedded component system (TINET+TECS), a component-based TCP/IP protocol stack for embedded systems. This component-based TINET offers software developers high productivity through variable network buffer sizes and the ability to add or remove TCP (or UDP) functionality. TINET+TECS utilizes a dynamic TECS component connection method to satisfy the original TINET specifications. The results of an experimental comparison between the proposed component-based and original TINETs show that the execution time and memory consumption overhead are reduced and the configurability is improved.
