Step 5: Compute the mapping cost of backup nodes and links.
We note that the objective function Eq. (3) minimizes the mapping cost of accepted MEC requests.
Since we are focusing on cloud computing and optical networking, we propose to calculate the mapping cost of each service request n, G n =(T n,A n ), as follows.
It can be calculated as follows: {M}_{mathrm{cost}}^{mathrm{total}}={sum}_{i=1}^{mid mathrm{ArrivedVN}mid }{M}_c^i, (5 where ( {M}_c^i ) represents the mapping cost of i-th VN demand and ArrivedVN denotes the set of arrived VN demand.
It can be calculated as follows: {M}_{mathrm{cost}}^{mathrm{bakNode}}={sum}_{i=1}^{mid mathrm{bakNode}mid }{M}_{mathrm{node}}^i, (6 where ( {M}_{mathrm{node}}^i ) denotes the mapping cost of the i-th backup virtual node and bakNode represents the set of backup virtual nodes.
