访问控制

If the destination IP address is local ,the router searches an internal store of IP addresses and local－device Media Access Control addresses. This store is known as the Address Resolution Protocol cache.

如果目的IP地址为本地的，该路由器就搜寻存储着IP地址和本地设备介质访问控制地址的内部存储器，这个存储器叫作地址分辨协议高速缓存。

In addition, access control policies of aggregated resources can be formulated as expressions of the algebra. Several algebraic properties of policy expressions are discussed. It shows that the algebraic properties of policy expressions can be used to verify whether policy composition results meet the protection needs of each party.

用代数表达式形式化地描述聚合资源的访问控制策略，讨论了策略表达式的若干代数性质，说明可借助策略表达式的代数性质去验证策略合成结果是否符合各方对聚合资源的保护性需求。

The High Speed Uplink Packet Access technology includes Adaptive Modulation and Coding, Hybrid Automatic Repeat Request, and Node B fast scheduling. It also solves the problem of sharing the uplink channel resources for User Equipment.

为了改善上行性能，高速上行分组接入主要考虑的技术包括自适应调制编码、混合自动重传、节点B快速调度，以及用户终端如何共享上行信道资源，同时包括增加增强的媒体访问控制实体，对协议进行增强和优化。

The High Speed Uplink Packet Access technology includes Adaptive Modulation and Coding, Hybrid Automatic Repeat Request, and Node B fast scheduling. It also solves the problem of sharing the uplink channel resources for User Equipment. Moreover, it has Medium Access Control protocol entities (MAC-e and MAC-es) to enhance and optimize the protocol.
