Introduction

Helen provides a Java Programming Language framework for generating UDP network traffic and a standard format for that traffic. Helen works on both Oracle JDK and Android (2.2/API Level 8) platforms. Networking can be complicated when you need to start a large number of packet generators and shut them down cleanly. Typically, programmers manage a large number of threads directly and manipulate the sockets by hand. This API manages those complexities for the user. In addition, the standard packet format (with clean options for extensibility) makes developing interoperable applications simpler.
