读懂物联网系列七:定制开发物联网网络 VS 计算机网络

众所周知,计算机能够实现上网功能是因为有网络的存在,如果没有计算机网络,那么赌博网就无法彼此之间收发消息,赌博网的计算机也就成了一个个的孤岛。对于计算机网络来说,TCP/IP协议又是其核心。可以这么说,TCP/IP协议是互联网能够飞速发展的技术基础。那么,传统的TCP/IP协议适用于物联网吗?要回答这个问题,赌博网先来看看物联网网络与计算机网络的差别。

终端数量

在一个计算机局域网下,物联网方案,终端数量通常在100台以下;而在一个局域物联网下,终端数量应该是在1000台以上。不光是终端数量多,还可能会有终端设备随时加入局域物联网中。
