Abstract
A node (100) is configured for use in a communication network. The node (100) is configured to obtain a message with a source address and a destination address. The node (100) is also configured to determine whether the message is a type of message that is sent in response to a different message routed from the destination address to the source address, and whether a forward route (16) from the destination address to the source address has been established. The node (100) is also configured to selectively transmit the message on a backward route (18) that is the reverse of the forward route (16), depending on the determining.

1-18. (canceled).
A method performed by a node configured for use in a communication network, the method comprising:
- obtaining a message with a source address and a destination address;
- determining whether the message is a type of message that is sent in response to a different message routed from the destination address to the source address, and whether a forward route from the destination address to the source address has been established;
- and
- selectively transmitting the message on a backward route that is the reverse of the forward route, depending on the determining.
A node configured for use in a communication network, the node comprising communication circuitry and processing circuitry wherein the node is configured to:
- obtain a message with a source address and a destination address;
- determine whether the message is a type of message that is sent in response to a different message routed from the destination address to the source address, and whether a forward route from the destination address to the source address has been established;
- and
- selectively transmit the message on a backward route that is the reverse of the forward route, depending on the determining.
A computer readable storage medium storing a computer program comprising program instructions that, when executed by a node configured for use in a communication network, configures the node to:
- obtain a message with a source address and a destination address;
- determine whether the message is a type of message that is sent in response to a different message routed from the destination address to the source address, and whether a forward route from the destination address to the source address has been established;
- and
- selectively transmit the message on a backward route that is the reverse of the forward route, depending on the determining.
