在流程执行模块中，本文主要研究了工作流实例的运行原理和引擎执行的设计、关键类的设计、并发聚合路由算法设计。
In the process execution model, the workflow instances execution principles and engine execution design, the design of the key classes and the parallel assembly routing algorithm are researched.
ESB可以支持更复杂和更成熟的路由模式，例如请求的分发和响应的相关性聚合，甚至是复杂的事件处理。
An ESB can support more complex and sophisticated routing patterns, such as distribution of a request and correlated aggregation of responses, or even complex event processing.
链路聚合提供了跨多个交换机路由通信流的机制，有助于防止交换机造成的网络故障。
Link aggregation provides a mechanism for routing traffic across multiple switches in the case of a network failure of a switch.
对子任务的结果进行聚合，产生并行路由任务的输出。
The output of the parallel routing task is created by aggregating the results from the subtasks.
如果事件存储器在一台机器上满了，那么根据聚合类型先进行分片处理是很容易的，然后还能根据聚合自己那一层再进行基于内容的路由分片。
If the event store outgrows a single machine, then it is easy to shard first by aggregate type, and with a little content-based routing even at the level of aggregates themselves.
路由聚合、路由重发布以及其他路由策略是BGP - 4协议必须实现的重要功能，本文深入讨论了实现这些功能的相关问题。
Route aggregation, routing redistribution and some other routing policies are the key abilities and must be implemented for BGP-4. The paper also discusses these routing polices deeply.
组播组的聚合使得网络中组播树的数量减少，路由器需要维持的组播转发状态和传递控制信息带来的控制开销都大大降低。
With multicast tree aggregation, fewer trees are maintained which amounts to reduce both the number of forwarding states in routers and the overhead induced by control messages.
