It means the more paths a link belongs to, the more critical it is (i.e. the more interference it causes). Because BGMRA uses only network topology to calculate criticality, this process is done independently of demand arrival and called offline phase. On the other hand, the online phase is the process to select route for arriving demands. Equation 3 shows the calculation of link weights in the BGMRA online phase. BGMRA has low computation time because link criticality is calculated in the offline phase and recalculation is needed only when the network topology changes.
