Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A source node for handling an Internet Protocol (IP) packet originating from the source node and addressing to a destination node in an IP communication network, wherein the source node is configured to:
obtain, from an application software installed on the source node, a first maximum delay of the IP packet between the source node and the destination node;
determine a second maximum delay based on a difference between the first maximum delay and at least one of an amount of a delay that will be caused by performing encapsulation of a data payload with a network layer header of the IP packet by the source node and an amount of a delay that will be caused by performing decapsulation of the data payload with the network layer header of the IP packet by a destination node addressed by the IP packet;
determine a time to drop the IP packet based on the second maximum delay;
encapsulate, at a network layer of the source node, the data payload with the network layer header to generate the IP packet, wherein the network layer header comprises an indication of the time to drop the IP packet; and
transmit the IP packet to a network node operating in the IP communication network.
