中文摘要：

网络虚拟化环境下，进行资源配置的一个重要前提就是虚拟资源的资源描述和发现，当前并没有针对虚拟环境中虚拟资源的特性提出合适的资源描述方法。本文通过分析虚拟资源的特性，提出一种资源描述机制．它能够描述不同粒度的虚拟资源。实验证明，对不同粒度的资源进行描述且采用本文提出的资源发现方法，资源配置效率会得到提升。

英文摘要：

The virtual resources description and discovery is an important premise for resources allocation in network virtual environment, however, there lacks efficient resource description method meeting the virtual resources characteristics in the current study. A new resource description mechanism was put forward which can describe virtual resources with different granularity by analyzing the virtual resources characteristics. And the efficiency of resource allocation has been promoted by the experiment using different granularity of resource description and this resource discovery method.
