Quality of Service (QoS) improving schemes in optical networks

Heliyon, 2020
In optical networks, such as OPS/OBS, the network results into significant loss in the network layer. When the loss significantly deteriorates the QoS by increasing the Bit Error Rate (BER), a viable approach can be used to increase the performance. This

A PSO-SVM for Burst Header Packet Flooding Attacks Detection in Optical Burst Switching Networks

Photonics, 2021
An Optical Burst Switching (OBS) network is vulnerable to Burst Header Packet (BHP) flooding attack. In flooding attacks, edge nodes send BHPs at a high rate to reserve bandwidth for unrealized data bursts, which leads to a waste of bandwidth, a decrease

A Formal Framework for Modeling Trust and Reputation in Collective Adaptive Systems [PDF]

, 2016
Trust and reputation models for distributed, collaborative systems have been studied and applied in several domains, in order to stimulate cooperation while preventing selfish and malicious behaviors. Nonetheless, such models have received less attention

K-Nearest Neighbors with Third-Order Distance for Flooding Attack Classification in Optical Burst Switching Networks

IoT
Optical burst switching (OBS) is a network architecture that combines the advantages of packet and circuit switching techniques. However, OBS networks are susceptible to cyber-attacks, such as flooding attacks, which can degrade their performance and ...
