In this paper we propose a novel clustering based multi-hop protection (referred to as
CMHP) heuristic scheme to protect against single shared-risk link group (SRLG) failure in a …

The next-generation passive optical networks (NG-PONs) are expected to offer very high
data rate to large number of users. Long-reach passive optical network (LR-PON) is …

Protection to optical network units (ONUs) against failure of their distribution fibers (DFs) in a
long-reach passive optical network (LR-PON) is highly desirable to provide uninterrupted …

Abstract Long-Reach Passive Optical Network (LR-PON) is known as a promising and
economical solution for Next-Generation PON (NG-PON). Survivability is one of the key …

In a long-reach passive optical network (LR-PON), protection for optical network units
(ONUs) against their distribution fiber (DF) failures is highly desirable to ensure …

In previous protection schemes against random double-link failure scenarios, two link-
disjoint backup paths are provided for each connection. However, the protection domains …

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

We propose a novel survivable algorithm, called backup-shared with trap avoidance (BSTA),
to protect against single failure with shared-risk link groups (SRLGs) in wavelength-division …

Ring-and-spur long-reach passive optical network (LR-PON) is the optimal network
architecture for next-generation passive optical network (NG-PON). Several protection …

Expanding size of passive optical networks (PONs) along with high availability expectation
makes the reliability performance a crucial need. Most protection architectures utilize …
