Abstract
Example embodiments of the present disclosure relate to enablement of a service function chain based on a software defined network. In some embodiments, there is provided a method implemented at a service function chain controller. The method comprises creating a service function chain for a packet, the service function chain comprising a set of ordered service functions that are to process the packet; and configuring respective forwarding rules associated with the service function chain directly or indirectly to a plurality of network nodes in a software defined network, the respective forwarding rules indicating how the plurality of network nodes forward the packet to the set of ordered service functions in the service function chain. In this way, it is possible to enable the service function chain in the software defined network.
