A method for a telecommunications system supporting multi-homing that means a capability to receive and/or send over two or more active communication links, the telecommunications system comprising at least a first apparatus, a second apparatus and an intermediate network node, the method comprising: listening, in the intermediate network node, at least two separate incoming links, a first incoming link for receiving packets from the first apparatus, and a second incoming link for receiving from the first apparatus packets that are copies of the packets received from the first apparatus over the first incoming link so that the intermediate network node receives first either the original packet or its copy; receiving, by the intermediate network node, a packet over one of the first and the second the incoming links; checking, by the intermediate network node, in response to receiving the packet, whether a corresponding original packet or its copy has been received earlier; if the corresponding original packet or its copy has been received earlier, discarding, by the intermediate network node, the packet; characterized by having, in the intermediate network node, information on apparatus capabilities that indicate whether an apparatus supports multi-homing or does not support multi-homing; performing, if the corresponding original packet or its copy has not been received earlier, by the intermediate network node, the following: checking, using the information on apparatus capabilities of the second apparatus, whether or not the second apparatus supports multi-homing; if the second apparatus does not support multi-homing, sending only the packet over a first outgoing link to the second apparatus, the first outgoing link being separate from the incoming links; if the second apparatus supports multi-homing, sending the copy of the packet over a second outgoing link to the second apparatus, the second outgoing link being separate from the first outgoing link and the incoming links, wherein each outgoing link from the intermediate network node and each incoming link to the intermediate network node is a direct link in a network, the first outgoing link and the second outgoing link are direct links between the intermediate network node and the second apparatus, and the first incoming link and the second incoming link are direct links between the intermediate network node and the first apparatus. listening, in the intermediate network node, at least two separate incoming links, a first incoming link for receiving packets from the first apparatus, and a second incoming link for receiving from the first apparatus packets that are copies of the packets received from the first apparatus over the first incoming link so that the intermediate network node receives first either the original packet or its copy; receiving, by the intermediate network node, a packet over one of the first and the second the incoming links; checking, by the intermediate network node, in response to receiving the packet, whether a corresponding original packet or its copy has been received earlier; if the corresponding original packet or its copy has been received earlier, discarding, by the intermediate network node, the packet; checking, using the information on apparatus capabilities of the second apparatus, whether or not the second apparatus supports multi-homing; if the second apparatus does not support multi-homing, sending only the packet over a first outgoing link to the second apparatus, the first outgoing link being separate from the incoming links; if the second apparatus supports multi-homing, sending the copy of the packet over a second outgoing link to the second apparatus, the second outgoing link being separate from the first outgoing link and the incoming links, wherein each outgoing link from the intermediate network node and each incoming link to the intermediate network node is a direct link in a network, the first outgoing link and the second outgoing link are direct links between the intermediate network node and the second apparatus, and the first incoming link and the second incoming link are direct links between the intermediate network node and the first apparatus.
