FLEXIBLE FRAMEWORK FOR MULTI-HOP ROUTING IN AN INTEGRATED ACCESS AND BACKHAUL NETWORK FOR 5G OR OTHER NEXT GENERATION NETWORK

In a 5G network, an integrated access and backhaul (IAB) network can experience radio link failures or radio blockage conditions in mmWave frequency bands. Local IAB nodes that experience such conditions can make route changes in response to such situations to prevent packet loss or significant packet delay. Thus, in an IAB network, local IAB nodes can also utilize a routing function that monitors local conditions of IAB links to determine whether a change in route is required or not. Additionally, the local IAB nodes can receive external routing updates that can preempt a local IAB node routing function. Consequently, the IAB node can consider local routing preferences and external routing preferences prior to updating a routing table of the IAB node.
