Multi-Failure Post-Fault Restoration in Multidomain DWDM Networks
Multi-Failure Post-Fault Restoration Multidomain DWDM Networks
2011/5/25
This paper proposes an adapted crankback-enabled post-fault restoration scheme against large-area failure events in multi-domain DWDM optical network. This novel solution provides recovery and resourc...
Migration based Protection for Virtual Infrastructure Survivability for Link Failure
Networks network survivability
2011/5/25
We propose a new migratory protection scheme that maps a virtual infrastructure to a substrate network using minimal resources to recover from a single substrate link failure. The efficiency of our so...
Experimental Evaluation of Centralized Failure Restoration in a Dynamic Impairment-Aware All-Optical Network
Centralized Failure Restoration Dynamic Impairment-Aware All-Optical Network
2011/5/20
A centralized impairment-aware lightpath restoration scheme is experimentally demonstrated. Through the implementation of the QoT estimator module on FPGA technology,restoration times of 1.36s are ach...
Multi-failure Restoration Demonstrations with Multi-vendor Interoperability in Control Plane enabled WSON
Multi-failure Restoration Demonstrations Multi-vendor Interoperability Control Plane enabled WSON
2011/5/18
We demonstrate multi-failure restoration in optical layer by using an eleven-node mul-ti-vendor WSON test-bed. Automatic restoration is achieved by deploying colorless and direction-less optical switc...
Availability-Aware SRLG Failure Protection in Survivable WDM Mesh Networks
SRLG Failure Protection Survivable WDM Mesh Networks Availability-Aware
2011/5/18
With the increase of SRLGs, availability of shared-path protection deteriorates significantly. We propose availability-aware SRLG failure protection and heuristics by satisfying availability requireme...
Survivable Mapping with Maximal Physical-Layer Failure-Localization Potential in IP over Transparent Optical Networks
Networks Network survivability Network optimization
2010/6/10
Physical-layer failure-localization potential is explored in finding the survivable mapped lightpaths of IP over transparent optical networks. Numerical results show that accurate or near-accurate fai...
Detecting faulty fiber with centralized failure detection system (CFDS) in fiber-to-the-home (FTTH) access network
detection of faulty fiber identification of failure location
2009/2/6
A new technique for detecting any faulty fiber and identifying the failure location occurring in tree-based structured fiber-to-the-home (FTTH) access network with centralized failure detection system...
