In a wireless network where a first data flow is transferred via a first path between two endpoints, a node buffers a second data flow. At least one of the two endpoints is in the wireless network. The first and second data flows comprise a same data. The node is in a second path between the two endpoints. In response to receiving indication the second data flow should be activated, the node sends buffered second data flow through the second path. A first node in the wireless network sets up the first and second data flows. The first node selects a second node in the second path to buffer the second data flow, and indicates to the second node that the second node is to buffer the second data flow and send data through the second data flow in response to receiving indication the second data flow should be activated.
