This paper systematically and roundly proposes the seven"technical walls"of network communications technologies we face after decades of exponential growth of the network bandwidth

number of transistors in the chip and number of software codes

including the"technical wall"of wireless mobile communication

IP data communication

fiber communication

Integrated Circuit（IC）

software complexity

big-data processing and energy consumption.These"technical walls"are relatively independent

interactive and itself-systematic.As you know

it is very difficult to turn over a"wall"

and it is more difficult to turn over the seven"walls"at the same period.This leads us to think strategically and globally.In addition to developing in the original way（"the trend is becoming smoother"

"changing growth patterns"

or"using new mode

new theory and new method"）

Is there another way to go?Instead of turning to every wall.From the perspective of future development

this path may be Artificial Intelligence（AI）of network communications

will gradually develop for decades or more

from low

intermediate

advanced

to super

so as to compensate for the lack of bandwidth without reaching exponential growth law as a possible way and option.At last paragraph

the network communications may become intelligent and the effect of AI is also given as"network AI body"to solve the operational problem and to greatly raise efficiency uninterruptedly for decades or more.
