Zusammenfassung:	A routing method checks a network path selected for transmitting a stream of packets between a first routing node and a second routing node in a computer network. The stream of packets complies with a first transport protocol. The method forwards, from the first routing node toward the second routing node, a set of handshake packets. The set of handshake packets includes change information indicating a change in the transport protocol for a plurality of the packets in the stream. The method modifies the plurality of packets in the stream ("modified packets"). Specifically, the method modifies the first transport protocol header in the plurality of packets in the stream to have a second transport protocol header of a second transport protocol. This modification preferably does not increase the packet size of each of modified packets.
