基于分步策略的微移动资源预留方案

在微移动/无线环境下，基于分步策略的资源预留方案针对延迟抖动敏感的实时业务，兼顾移动主机RSVP切换的延迟时间和网络资源利用率，该方案以RSVP切换延迟为目标进行路径选择及资源预留，预留完成后在此路径上临时性地继续实时业务的数据传输，在数据传输期间对RSVP临时路径的网络资源利用率进行优化，并保持路径优化操作与数据分组的传输并行执行。RSVP优化路径一旦建成，就立刻将数据传输转移到此优化路径上，并释放以RSVP切换延迟为目标的临时预留路径。性能分析表明，在RSVP切换延迟和资源利用率上，基于分步策略的微移动资源预留方案均取得了优越的性能。

Resource-reservation Scheme for Micro-mobility Based on Step-by-Step Strategy

In order to adapt agile alteration of examination and approval of business and improve system flexibility in enterprises, this paper proposes a custom model and its implementation scheme for examination and approval of business. The process of examination and approval is decomposed into several characteristics sets, such as objects, custom processes, roles, and so on. And the characteristics are defined by n-tuple of types, attributes and states. Dynamic configuration and real-time alteration of the examination and approval process can be realized by a characteristic matching algorithm. This scheme has been implemented actually during the grouping course of an enterprise and proved effectively to reduce 90% modification time caused by changing the examination and approval activities.
