简介:分布式的研究与学术gigabits开的网络实验室(龙实验室)是为与基于用三的同盟网络,层遮蔽结构的下一代因特网(NGI)有关的研究目的唯一的试验台。作为NGI的必要部分,与事情(IoT)的因特网有关的研究设备应该在龙实验室站台上被使用。这篇论文建议一条途径到由集成在龙实验室和IoT之间的云结构的每层集成IoT设备到同盟网络。这项研究活动扩大龙实验室的使用,做IoT和在同盟网络工作很好的无线传感器网络(WSN)设备。它也是为三层云结构的foundational研究,它能为另外的相关研究被再使用。最后,它为IoT因特网协议版本6完成准备工作(IPv6)设备在龙实验室研究,它为NGI是必要的。

简介:一、产品简介梅捷P4I875PDRAGON2是一款基于875P的主板,有关875P的特性介绍大家一定都耳熟能详了,这里就不多费笔墨了。主板CPU插槽的背部放置了一个X型支架,使得主板放在手里感到很有份量,北桥采用倾斜45度角设计,相比传统的正置式北桥,可加大MCH到内存之间的引线间的距离,减少引线之间的干扰,更有利于信号的传送。主板上的电容不论容量大小一律采用SACON的电解电容,主板的做工中规中矩。南桥采用了内置RAID功能的ICH5R,加装最新的IAA驱动可提供SATARAID0和RAID1两种RAID模式,主板BIOS的外频调节范围非常大,可线性调节至
