Abstract
A method for encapsulating a packet of data from a data flow is described. The packet comprises a flow network header for identifying a source network address and a target destination network address and a flow transport network header for identifying a source port and a target destination port. The method comprises the following steps. The flow network header is replaced with an encapsulation network header for identifying an encapsulation network address and a decapsulation network address. The decapsulation network address specifies the address of a decapsulation node. The flow transport header is replaced with an encapsulation transport header for identifying an encapsulation port and a decapsulation port. The decapsulation port is configured to be the same as the target destination port. A method for decapsulating the encapsulated packet, as well as network nodes configured to implement the methods, are also described.
