“…Equations (7) and (8) ensure that a backup path cannot enter the source or exit the destination. Equation (9) ensures that each recovered request has an available backup path. Equation (10) finds the maximum occupancy ratio of all the links where is a constant to avoid , being 0.…”

“…The main idea of both the articles is to let subsequent requests reuse the light paths established for previous requests, so that resource contention could be reduced. Reference [9] studies restoration in wavelength convertible wavelength switched optical network (WSON) and wavelength converters are utilized during restoration in order to avoid restoration contention. However, most of the previous works focus on wavelength resource while, in this paper, we mainly pay attention to the bandwidth resource.…”

“…Owing to the criticality of the transport infrastructure, network resilience and survivability has received increasing attention during the past decades. Early studies took their starting point in the single failure paradigm, considering and resolving that only one component (typically a link) could fail at a time, and many studies proposing advance recovery mechanisms and capacity optimisation were conducted, see, for example, [4, 5]. As the networks have been spreading geographically, the probability of two non‐correlated failures at two or more network locations have received more interest and multi‐failure recovery scenarios have been analysed, for example, in [6].…”
