Proposal Number 0203876Title: "Smart Event Models and Architectures"Gail E. Kaiser, Columbia UniversityThis project investigates wide-area publish/subscribe event system models and architectures. The focus is on two new models called Smart Events and Active Events, and an event bus architecture called Virtual Private Event Networks (VPENs).Smart events are associated with a structural type model (a grammar or schema), and a semantic model that defines the processing to be performed on the structural subcomponents. Smart events are routed via content-based messaging, where subscriptions may specify complex patterns indicating the events of interest. Active events include their semantic model directly as mobile code. Active events operate asmobile agents transported (conceptually) under their own power point-to-point. Smart events may optionally include active event substructures, enabling content-based messaging to be applied to this subset of active events.VPENs extend multi-protocol label switching (MPLS) protocols and mechanisms to the application layer, to improve the performance of content-based routing by preplanning label switched paths when publisher advertisements as well as consumer subscriptions are available. VPENs also add encryption-based security and privacy in the style of virtual private networks (VPNs).

提案编号0203876TITLE：“智能事件模型和体系结构” Gail E. Kaiser，哥伦比亚大学本项目研究广阔的地区发布/订阅事件系统模型和体系结构。 重点是两个称为智能事件和活动事件的新模型，以及一个称为虚拟专用事件网络（VPENS）的事件总线体系结构。SMART事件与结构类型模型（语法或架构）相关联，以及定义要在结构子组件上执行的处理的语义模型。 智能事件是通过基于内容的消息传递的，订阅可以指定复杂模式，以指示感兴趣的事件。主动事件将其语义模型直接作为移动代码。活跃的事件在自己的力量点对点下（从概念上）操作被运输的Asmobile代理。 智能事件可能会选择包括活动事件子结构，使基于内容的消息传递可应用于此活动的活动。VPENS将多协议标签交换（MPLS）协议和机制扩展到应用程序层，以通过发布商广告以及使用的消费者订阅时，通过预先销售标签开关路径来改善基于内容的路由的性能。 VPEN还以虚拟专用网络（VPN）的方式添加了基于加密的安全性和隐私。
