Due to the conventional “best-effort” approach that had no guarantee of packet delivery, the
Internet was not initially developed for the purpose of sending real-time traffic. However …

This paper concerns Quality of Service (QoS) provisioning in Optical Packet Switching (OPS)
networks. We address the topic by proposing Dynamic Wavelength Grouping (DWG) for …

This paper presents the optical contention detection circuit for all-optical network operating
at data rate of 120 Gbps with enhancement of four wave mixing (FWM) intereaction between …

The ubiquity of instant messaging (IM) apps on smart phones have provided criminals to
communicate with channels which are difficult to decode. Investigators and analysts are …

This paper presents a broadband optical packet generation method by multiplexing low-and
high-frequency signals using a bias tee. The cut-off frequency of the bias tee, fc is optimized …

Contention of optical packets in optical packet switched (OPS) networks is a major problem,
and it is even more critical in buffer-less OPS networks. In this paper, an innovative …

Cybercrimes are emerging trends on the Internet. Free instant communications, like LINE or
WhatsApp, bring close to our family and friends around the globe. People in Taiwan use …

In this paper, we propose a large-scale transparent optical datacentre network with a
coordinated congestion management technique, combining optical Fibre Delay Line (FDL) …

The Four Wave mixing (FWM) based contention detection circuit has the high performance
in term of bit error rate for the contention detection signal. For the amelioration in the Quality …

Sniffers are among the commonest approaches for capturing network traffic activities and
collecting digital evidences in cybercrime investigations. The ubiquity of instant messaging …
