IoT Backbone 网络的骨干

A few key components to an Internet of Things architecture.
IPv4 and IPv6 “互联网协议版本6（IPv6）是互联网协议（IP）的最新版本，该协议为网络上的计算机提供识别和定位系统，并通过互联网路由流量。互联网上的每台设备都必须分配一个IP地址，以便与其他设备进行通信随着新设备连接到Internet的数量不断增加，需要为IPv4提供比IPv4更多的地址，IPv6使用128位地址，允许2128或大约3.4×1038个地址，或者大于使用32位地址的IPv4的7.9×1028倍。	Description: "Internet Protocol version 6 (IPv6) is the latest revision of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.Every device on the Internet must be assigned an IP address in order to communicate with other devices. With the ever-increasing number of new devices being connected to the Internet, the need arose for more addresses than IPv4 is able to accommodate. IPv6 uses a 128-bit address, allowing 2128, or approximately 3.4×1038 addresses, or more than 7.9×1028 times as many as IPv4, which uses 32-bit addresses.'
UDP 用户数据报协议（UDP）是互联网协议套件（用于互联网的一组网络协议）的核心成员之一。利用UDP，计算机应用程序可以将消息（在这种情况下称为数据报）发送给其他在没有事先通信的情况下在互联网协议（IP）网络上建立专用传输通道或数据路径的主机。“ IETF Page	Description: "The User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite (the set of network protocols used for the Internet). With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network without prior communications to set up special transmission channels or data paths."
TCP “传输控制协议（TCP）旨在用作分组交换计算机通信网络中主机之间以及这些网络的互连系统中高度可靠的主机到主机协议。” IETF Page	Description: "The Transmission Control Protocol (TCP) is intended for use as a highly reliable host-to-host protocol between hosts in packet-switched computer communication networks, and in interconnected systems of such networks."
6LoWPAN “6LoWPAN是低功率无线个域网上IPv6的缩写，6LoWPAN组定义了封装和报头压缩机制，允许IPv6数据包通过基于IEEE 802.15.4的网络发送和接收。” IETF WG RFC 4944 Wiki	Description: "6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks. The 6LoWPAN group has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent to and received from over IEEE 802.15.4 based networks."
