Network traffic monitoring using embedded target-side analyzer during embedded software development

摘要

A debugging system running on a host device uses an embedded target-side network analyzer to acquire communications information such as packets. The target-side network analyzer logs and analyzes packets by obtaining data from the target's Internet Protocol (IP) stack when diagnostic functions are invoked at breakpoints. This allows display, logging, analysis and other uses of decoded network traffic. This approach can be used in applications (e.g., wireless or those using protocols such as RADIUS and PPP, etc.) where identifying and intercepting traffic to or from a specific target device may be difficult or impossible. With this approach developers can analyze network traffic in real time without any special hardware.
