网络有其特有的服务质量（QoS）等级和QoS机制。因此，为了在异构网络中支持端到端的QoS，需要有一定的统一控制，如带宽代理（BB）和QoS管理服务器（如RACF）。但由于管理复杂、实现困难等原因，导致了可扩展性问题。有一个强烈的需要，以提供简单的QoS互操作性，所以我们提出了一个QoS类映射（QCM）框架：适当的构建块应定义，如参数到类映射和类到类映射，以选择最合适的QoS类异构网络。并对该框架进行了改进，使其不仅能提供完善的QoS类别映射，而且能提供有希望的细粒度QoS服务。该框架采用了应用服务映射（ASM）。由于ASM的位置信息（LI）代表了绝对的QoS需求，它可以全局使用，并提供完美的QoS类映射。作为一个实验结果，我们证明了所提出的框架，在异构网络支持QoS的性能。实验结果表明，该框架能够支持细粒度服务。
A network has its own peculiar Quality-Of-Service (QoS) class and QoS mechanism. So, to support end-to-end QoS in heterogeneous network, a certain unified control is needed as Bandwidth Broker (BB) and QoS management servers (such as RACF). However, it causes scalability problem as management complexity and implementation difficulty. There is a strong need to provide simple QoS interoperability so we present a QoS Class Mapping (QCM) framework: proper building blocks should be defined such as parameter-to-class mapping and class-to-class mapping for selecting the best-suitable QoS class over heterogeneous network. And we improve the framework to provide not only perfect QoS class mapping but also promising fine-granular QoS services in the circumstance. This framework employs Application Service Map (ASM). As Location Information (LI) of ASM represents absolute QoS requirements, it can be globally used and provide the flawless QoS class mapping. As an experimental result, we demonstrate the performance of the proposed framework for supporting QoS over heterogeneous network. In addition this experimental result shows the proposed framework can support fine granular service.
