Abstract
There is provided a method in a communication network system 100 of e.g. IP type for live distribution of media content capable of node-to-node time-transfer between nodes in the network system. The media content is sent as a data stream DSx via respective communication links over a network 200. The method comprises transferring local clock signal between nodes and based on received local clock signals determining a unidirectional delay between the nodes. The traffic between the nodes is then based on the determined unidirectional delay.
