TL;DR: It is shown that the length of the polling cycle plays a crucial but different role for the operation of the DBA within the two standards, EPON and GPON, which are major standards for PONs, Ethernet PON and gigabit PON.

TL;DR: This article provides a comprehensive overview of potential physical-layer attack scenarios in current and future optical networks and proposes a general security framework, outlining possible strategies for dealing with such attacks, meant to aid in the development of efficient provisioning, monitoring, protection, and restoration schemes in the context of optical-layer security.

TL;DR: Two distributed approaches that integrate information about most relevant physical impairments in RWA and lightpath provisioning are presented and assessed and functional requirements, architectural functional blocks, and protocol extensions for implementing either an impairment-aware real-time RWA, or a light Path provisioning based on impairment- aware signaling are provided.

TL;DR: The aim is to give a guideline for the design of the most cost-effective protection schemes, while maintaining acceptable service reliability, in any type of fiber access network.

TL;DR: This work proposes to route lightpaths in such a way as to minimize the potential damage caused by various physical-layer attacks, and presents a new objective criterion for the routing and wavelength assignment (RWA) problem, which is called the maximum Lightpath Attack Radius (maxLAR).
