【KW41Z】继续讨论关于Border Router
[复制链接]
A Thread Border Router minimally supports the following functions: - End-to-end IP connectivity via routing between Thread devices and other external IP networks
- External Thread Commissioning (for example, a mobile phone) to authenticate and join a Thread device to a Thread network
OpenThread's implementation of a Border Router is called OpenThread Border Router (OTBR). OTBR includes a number of features, including: - Web UI for configuration and management
- Thread Border Agent to support an External Commissioner
- NAT64 for connecting to IPv4 networks
- Thread interface driver using wpantund
-----------------------------
Thread边界路由最基本功能
1，通过路由实现端到端的IP连接，Thread设备和其他的外部IP网路之间
2，外部Thead调试，认证和加入Thread设备到Thread网路钟。
-----------------------------
OpenThread实现了一个边界路由，被称为是OpenThread Border Router，缩写是OTBR，后续我们讨论采用这个缩写。
OTBR包含以下功能
1，WEB网页用于配置和管理
2，Thread路由代理用于支持外部接入
3，NAT64用于连接到IPv4网路
4，使用wpantund作为Thread接口驱动
Border AgentThe Border Agent binds to both Thread and WAN (WiFi, Ethernet) interfaces, to support an External Thread Commissioner in authenticating and joining Thread devices." It also provides support for the NCP design, where Thread functions are offloaded to an NCP and OTBR runs on the host side. In this design, the Border Agent communicates with the NCP via and . A Border Agent Proxy provides an interface between Spinel and OpenThread's CoAP client and server components on the NCP. For communication with an external Commissioner, the Border Agent uses standard UDP sockets. The Border Agent utilizes the following third-party components: - libcoap — An open source C-implementation of CoAP implementation
- mbed TLS — Supports DTLS communication with an external Commissioner
以上两幅图，没看太明白，欢迎大家参与讨论。
看OpenThread已经支持很多厂家的平台，这几年802.15.4芯片可选的越来越多了，前几年基本上很少。
