A high-speed downhole network providing real-time data from downhole components of a drilling strings includes a bottom-hole node interfacing to a bottom-hole assembly located proximate the bottom end of a drill string. A top-hole node is connected proximate the top end of the drill string. One or several intermediate nodes are located along the drill string between the bottom-hole node and the top-hole node. The downhole network is configured to include a data rate adjustment module to monitor network traffic traveling in both uphole and downhole directions. The data rate adjustment module is configured to optimize network settings and efficiency by adjusting the allocation of available network bandwidth for data traffic traveling uphole and downhole.
