| Our research work concerns providing highly expressive, reconfigurable customization mechanisms for distributed event systems to achieve better runtime results in supporting plug-and-play style applications, making applications using distributed event systems both easier to construct and with desirable runtime performances. Two objectives of our research are: (1) to show the necessity of distributed event system middleware to offer reconfigurable individualized customization to support plug-and-play style applications from heterogeneous, decoupled, dynamic components, and (2) to identify and investigate the issues that are important in building such distributed event system middleware.; Our research results are represented by JECho, a Java-based implementation of efficient, customizable, reconfigurable distributed event systems. JECho's eager handler mechanism supports aggressive component customization. It supports runtime reconfiguration of eager handlers, and their automatic generation and adaptation. Its active broker and third-party derivation provides a mechanism for building higher level constructs in supporting dynamic component behavior, and its JEChoSync framework provides a novel individualized synchronization mechanism for anonymous peer-to-peer environments. |
