TL;DR: In this paper, an architectural concept is discussed and justified mathematically that relies on cascading many small switches to form a bigger switch with a larger buffer depth, providing an economical and feasible hardware solution.

TL;DR: A resilience strategy is introduced for networks implementing dual homing (dual parenting) of customers, specifically those employing Long-Reach PONs (LR-PONs), and it is shown that signalling time lies well within 50 ms, leaving sufficient time for redirection of user traffic.

TL;DR: This paper reports on proposed solutions to the recovery from faults in a generic class of networks, where customer access is achieved via long-reach passive optical networks (LR-PONs), with the majority of customers enjoying protection in the backhaul regime to two separate metro nodes.

TL;DR: A resilience strategy is introduced for networks implementing dual homing (dual parenting) of customers, specifically those employing Long-Reach PONs (LR-PONs), and the protocols which propagate information about the reachability of LR-Pons and those that re-route traffic in the event of a fault are discussed.
