Abstract:
Provided are a method and device for processing a data packet. The method is applied to a software defined network (SDN), the SDN comprising a controller, at least one switch and a plurality of network functions (NF). The method is executed by the controller, the method comprising: determining that a data flow needs to be migrated from a first NF in a plurality of NFs to a second NF in the plurality of NFs; sending a first instruction to the first NF; sending a second instruction to the second NF; sending a first forwarding rule to a first switch in at least one switch, the first forwarding rule being used for instructing the first switch to add a label to a data packet of the data flow, and to send the data packet carrying the label to the first NF and the second NF or a switch connected to the first NF and a switch connected to the second NF; and finally, migrating the state of the data flow of the first NF to the second NF. The method and device for processing a data packet in the present application can save on the overheads of a controller and shorten the time for state migration.
