某公司欲开发一个用于分布式登录的服务端程序,使用面向连接的TCP协议并发地处理多客户端登录请求。用户要求该服务端程序运行在Linux、Solaris和WindowsNT等多种操作系统平台之上,而不同的操作系统的相关API函数和数据都有所不同。针对这种情况,公司的架构师决定采用“包装器外观(Wrapper Facade)”架构模式解决操作系统的差异问题。具体来说,服务端程序应该在包装器外观的实例上调用需要的方法,然后将请求和请求的参数发送给(),调用成功后将结果返回。使用该模式()。
A.客户端程序 B.操作系统API函数 C.TCP协议API函数 D.登录连接程序 A.提高了底层代码访问的一致性,但降低了服务端程序的调用性能 B.降低了服务端程序功能调用的灵活性,但提高了服务端程序的调用性能 C.降低了服务端程序的可移植性,但提高了服务端程序的可维护性 D.提高了系统的可复用性,但降低了系统的可配置性

With the explosive popularity of mobile devices, we have witnessed a steady increase in demand for mobile date service. In addition mobile users also expect to connect to the Internet for communicate and access to services through the best suitable connection, anywhere and at anytime. Although the seamless roaming capability is well supported in conventional. Cellular communication networks, roaming and interworking technologies are still immature in heterogenous wireless networks. Seamless roaming over heterogenous wireless networks will be an ongoing and improved process, due to the requirements from both end users and network administrators. From the wireless access networks belonging to different administrative domains, mobile users cannot always identify at every instance which network is the best one to access for their service. It is highly demanded to establish a network architecture which can facilitate mobile terminals to access the appropriate network in a cost-effective way. If a mobile user wants to move from one network to another with continuous service, the terminals have to cope with network change to maintain service seamlessly. Quality of service is a major issue that the end users should be provided with the satisfying service, while the network workload and cost should not too much increased. In addition, since end users are provided with numerous service ranging from Voice-over-IP to Video-on-Demand services, it is expected that users can experience the same quality for all the different service. Therefore, the network architecture need to be designed in such a way that the quality mechanism is incorporated so that users are served according to their individual QoS requirements. Based on the paragraph above, at present, seamless roaming over heterogenous wireless network is () in conventional cellular communication networks, Because of (), mobile users cannot always identify at every instance which network is the best one to access for their services. To satisfy the users QoS requirements, the network architecture design should include () A.better than
B.maturer than
C.as good as
D.not as good as
49.A.the different network administrative domains
B.the same network administrative domains and mobile users
C.mobile users
D.the same network administrative domains
50.A.Voice -over -IP
B.the quality mechanism
C.workload
D.Video-on-Demand
