Processing of Data Traffic in Integrated Access and Backhaul (IAB) Communication Networks

The present disclosure relates to methods and nodes in an integrated access and backhaul (IAB) network. In one aspect, a method for a local breakout, performed in a first network node of the IAB network is provided. The first network node is being in communication with a core network, and the method comprises providing a network connection between the first network node and a local data network having a first network address, receiving a data traffic, transmitted by a user equipment (UE), wherein the data traffic is destined for a central application server having a second network address and being in communication with the core network. If the at a traffic meets a requirement for the local breakout from the first network node, the method comprises forwarding the data traffic to a local application server of the local data network and receiving from the application server of the local data network, a selected part of the data traffic destined for the central application server. The method further comprises transmitting the selected part of the data traffic to the central application server, whereby mitigating data traffic overload of the IAB network.
