Next Generation Passive Optical Networks-2 (NG-PON2) are being considered to upgrade
the current PON technology to meet the ever increasing bandwidth requirements of the end …

Network survivability is becoming a key issue in Passive Optical Networks (PONs). In
conventional PONs, optical protection is applied to improve the network survivability …

The availability of an optical connection is considered to be a critical service differentiator in
WDM optical networks. In this regard, the design of a protection scheme that improves the …

Recent trends in bandwidth markets show that customers are tending to ask providers for
large bandwidth, but for limited amount of time to support new short term bandwidthhungry …

Survivability of Elastic Optical Networks (EONs) from a link failure is an important problem.
Shared Backup Path Protection (SBPP) is widely used for protection against a link failure …

Survivability is the key topic in the networks. This paper studies the shared-protection based
on SRLG, and presents two algorithms. The effectiveness of the proposed algorithms is …

This work presents algorithms for the planning phase of wavelength division multiplexed
(WDM) optical networks considering the impact of physical layer attacks. Since the signals in …

Two important challenges in designing a survivable optical network are minimizing backup
spectrum allocation and ensuring spectrum assignment constraints. Allocating backup …

Energy efficiency has become an increasingly important aspect of designing access
networks, due to both increased concerns for global warming and increased network costs …
