It should be noted that processor 20 uses DMA (Direct Memory Access, direct memory access) two layers of net
Lattice agreement, device link selects and being switched fast only needs 50-100ms to complete, and the switching between network is for end user
It is transparent, has reached the ability of seamless switching；
Further, processor 20 also reduces handling capacity damage using the wireless broadband transmission technology based on Internet of Things.
Here, FifthNet (the 5th network) is greatly reduced using the technology of the wireless broadband transmission based on Internet of Things
The throughput loss often jumped；
Wherein, in laboratory environments, often jump loss and be less than 1%；In actual applications, often jump loss and can reach and be less than
10%.Such as 5 kilometer of 10 jump site environment, in network end to end from the beginning to the end, at least more than 100Mbps can be provided
Handling capacity, and conventional mesh networks, single-hop decay reach more than 50%；
Fig. 3 is the three of the structural representation for the networking equipment that the embodiment of the present invention one provides.
Shown in reference picture 3, processor selects IPQ4019, and is provided with three radio frequency boards to the left, is only in Fig. 3
A kind of example, it is not limited to which three radio frequency boards, the quantity of radio frequency board at most may be configured as six；
Wherein, several network interfaces are provided with the right side of processor, by network interface successively with selecting switch and processing
Device is connected；
