This event-condition-action(ECA) rule description language for Web Services(named WS-ECA) is the latest buzzword in the realm of autonomous, intelligent agent based Web Service oriented computing (AWSOC). This rule description language supports interactions among service oriented, heterogeneous devices in a pervasive computing environment. It is based on ECA rules, which are embedded in distributed service devices and are triggered by events from internal or external factors. In this paper, we report our ongoing efforts to use DamlRuleML to define the ECA rules for a hybrid SNMP and mobile agent (MA) based network management system (NMS) we have built in-house. Our work is a novel approach embedding ECA Rules into AWS (agent Based Web services) which is used to enable pervasive network management.
