چکیده

This paper focuses on the design and implementation of a low-complexity dialogue mechanism between the management and transport planes of an alloptical network. This dialogue aims at exchanging relevant information from monitoring the performance and degradation of optical signals with minimal disturbance to the optical services and minimum knowledge of the transport history of data, with a view to ensure service quality. Complexity of the dialogue is measured in terms of response delays in the event of failures.

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks

Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of  regeneration capabilities, the physical layer i...

Node wrappers for QoS monitoring in transparent optical nodes

Transparent optical nodes (TONs), such as all-optical switches and erbium-doped fiber amplifiers, are an increasingly important part of wavelength-division multiplexed (WDM) networks. Our goal in this paper is to consider how quality of service (QoS) may be monitored at such TONs. The question is particularly important as access to WDM networks, and associated security concerns, increase. Our p...

Optimal Monitoring Equipment Placement for Fault and Attack Location in Transparent Optical Networks

Last decade, network security has become a very sensitive and important topic for equipment manufacturers and network operators. Physical layer security in opaque optical networks relies on the information obtained at the opaque nodes where the signal is electronically regenerated. However, in transparent optical networks, security is even more complex since the optical signals are not regenera...

Optical Networks Security: A Failure Management Framework

Network security is becoming a very sensitive and important topic for equipment manufacturers and network operators. In transparent optical networks, security is even more complex since the optical signals are not regenerated as in opaque networks and, therefore, the faults and attacks at the physical layer are more difficult to detect and isolate without significantly affecting the overall net...
