Abstract
According to an example aspect of the disclosed embodiments, there is provided passive routing in a mesh network. One or more media frames from source nodes to target nodes in the mesh network are received. Routing information from a received media frame is derived, said routing information including a source node identifier, a target node identifier, a last node identifier and a frame identifier. The derived routing information is stored into a route ring buffer. A reverse route for the received media frame is determined. The received media frame is prevented from being forwarded in the mesh network, when the route ring buffer includes routing information corresponding to the reverse route.
