Abstract	To enhance system survivability when the original mapping scheme fails caused by the change of underlying infrastructures, a dynamic resource virtualisation method based on software definition network (SDN) is proposed. First of all, modelling and formalisation of dynamic resource remapping under SDN environment are constructed, which make the entity resources controlled in the network. Then, resource constraints and evaluation objectives of mapping are considered, and the remapping procedures of nodes and links are described in the case of failure of physical resources. During the process, the detachment factor is introduced as the index to evaluate whether the virtual nodes and links need to be separated, and further be allocated by the greedy algorithm reasonably and dynamically, to realise the virtual network requests. Finally, the simulation experiments are carried out and show that the proposed method is superior to other related methods in virtual request acceptance rate, resource utilisation and average waiting time of service; as a result, improving survivability under the condition that the underlying physical resources change in real time.
