Alibaba Cloud Internet of Things Platform Defects

Diversity of Internet of Things protocols and fragmentation of devices.

All sub-devices reuse the same physical channel, and the gateway proxy sub-devices are online, and each sub-device corresponds to a virtual connection session. Subdevices are considered as directly connected devices. The only difference is that directly connected devices have independent channels, and sub-devices enjoy physical channels. A gateway has multiple physical connections, and each physical connection is equivalent. The gateway can send or receive data to any physical connection.

The advantage is that it solves the multi-identity problem of the edge gateway, and multiple physical channels are equivalent to multiple copies. When there is a problem with a single access service, the gateway can send and receive messages through other connection channels without any impact on the service.
