This paper addresses the issue if a home gateway is capable of running the to-be-downloaded new services or bundles. Such an issue has been ignored in applications for personal computers or for dedicated embedded systems. However, for a home gateway that connects home appliances either wired or wirelessly to internet, users are free to choose new services. We assume that most home users of gateways are not familiar with the settings of the middleware on gateways. Hence once a new service should degrade the performance of the gateway, the problem is dramatic because the user would not know how to kill or stop the service. Our approach is to design and develop a tool which measures and evaluates both the resource requirements of the to-be downloaded service(s) and the remaining capability of the target gateway before deployment. This tool is assumed to be applied by system operators. The size of the tool is 45 KBytes and its overhead is 12 ms in average, as measured with testing services on a PC-based OSGi (Open Service Gateway initiatives) platform.
