Plus, deploying cache can help users postpone expensive network upgrades that were meant to improve Internet access time. 此外,安装缓存能帮助用户延缓昂贵的网络(EN)升级,这种升级是要缩短因特网接入的时间。
Therefore, it is clearly inappropriate to adopt the traditional caching technology in the unstable network connections, limited network resources and expensive network communication mobile computing environment. 因此,对于网络连接不稳定、网络资源十分有限、网络通讯代价昂贵的移动计算环境,采用传统缓存技术显然是不合适的。
The satellites in space and the communication links between the satellites and ground nodes are expensive network resources, so it is very important to make full use of that in order to guarantee quality of service. 空间中的卫星以及星地通信链路都是高成本的网络资源,如何充分利用有限的网络资源、保证服务质量则是研究这类网络时必须考虑的问题。
The network experiment is important to the learning of computer network knowledge, but experimental environments are not always available because of the diversity of the network structures and expensive network devices. 组网实验对于学习计算机网络知识非常重要,但是由于网络结构的多样性和网络设备的昂贵价格,真实的组网实验环境通常很难获得。
The module replaces expensive outboard network adapters and eliminates the requirement for an additional enclosure, cabling, and power supplies. 该模块可取代昂贵的外置网络适配器,降低对配件、布线和电源的要求。
