Apparatus, method and computer program for group communication

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus to perform:
• receiving user plane traffic at the apparatus, the user plane traffic intended for a group local area network communication;
• determining a target destination address for the user plane traffic;
• and
• autonomously handling the received user plane traffic at the apparatus in dependence on the target destination address;
• and
• wherein the autonomously handling the received user plane traffic by the apparatus comprises determining whether the destination address is recognised by the apparatus;
• determining whether the user plane traffic has already been forwarded by setting a hop-count parameter that avoids the user plane traffic being forwarded that has already been forwarded;
• and
• forwarding the user plane traffic towards all interfaces tagged as network interfaces associated with the group communication, when the destination address is determined to be not recognised by the apparatus, wherein when forwarding the user plane traffic, a tunnel header is included that identifies whether or not the user plane traffic has already been forwarded.
