In variable rate networks,the source transmits different number of message packets to sinks at different time. If the maximum flow from source to a distination is not less than the information rate,the sink is required to retrieve all the message packets. Focusing on the issue,we deduce the global and local transfer matrix from the data transmission point of view. Moreover,we obtain the condtions of achieve successful communication in variable rate networks and get an approach of how to construt variable rate linear netwok code. What's more,our method can also be used to construct linear network codes for variable rate networks with link failure and guarantee the robustness of these networks.
