摘 要：In disadvantaged grids, communication resources are scarce and variable. Thus, it is important that middleware and applications are able to adapt to the available capacity. This means that knowledge of the networking environment the C2 software is operating in is of great importance. Monitoring of networks carrying data is important in improving quality of service. There are two main types of monitoring: monitoring in the planning phase; and monitoring during deployment. Here, it is important to know the current load (e.g., link utilization) to be able to shape and control data traffic in a coherent manner. There exist many solutions capable of doing this, but they are mostly geared towards use on the Internet and in corporate networks. Sending data to and from mobile units, like military vehicles moving in a combat zone, provides challenges that may make some current tools unsuitable. In this paper, we focus on freely available tools, and attempt to identify which tools are suitable for the planning phase and which are suitable for the deployment phase in disadvantaged grids.
