The high efficient embedded Internet node expansion was the most foundation work for the development of the next generation in embedded system.In traditional Internet node expansion method

the TCP/IP and fuzzy jump method were used

when the number of nodes was large

it cannot achieve efficient expansion.The extending design of internet nodes with fuzzy pushpin extending method was proposed

before node expansion

the 7 levels model of the node was analyzed

and then the fuzzy pushpin extending function was used to choose the best way

with the optimal expansion method

and the efficient embedded Internet node expansion was achieved.Finally

a team of 20-nodes system was used to test the ability

the experimental result shows that with fuzzy pushpin extending method

the system pushpin is very good

and very it can achieve efficient expansion between nodes

so it has good value for network application.
