Optical packet switching (OPS) has been considered to be a promising paradigm to support a wide range of applications with different time-varying and high bandwidth demands for future optical metropolitan area networks (MANs). In this paper, we present the design of an experimental optical-header processing and access control system (OPACS) for an OPS(More)
Over the last decade, advances in Internet technology brought about the proliferation of Internet-based multimedia applications, particularly known as Internet Protocol Television (IPTV) services. In the large-scale, heterogeneous, multi-vendor, and increasingly complex and multi-functional IPTV networks, the quality assured provisioning is one of the key(More)
The explosion of the mobile broadband data traffic and the expected needs of ever increasing bandwidth demand present great challenges and opportunities for mobile operators. To mitigate the challenges, mobile operators usually offload mobile data traffic from cellular networks to alternative networks by utilizing IEEE 802.11 wireless fidelity (Wi-Fi)(More)
IEEE 802.11 Wireless Local Area Networks (WLANs) has become one of the most popular networking environments. With high density WLANs, it causes the interference among access points (APs) and degrades the performance of APs, especially in public area. To solve this problem, we design and implement a Cluster-based Channel Assignment (CCA), a combination of(More)
The tremendous bandwidth demand for content-rich services on service providers initiates new access networks deployment and leads the networks increasingly complex and functional. In general, the commercial access networks are composed of a large number heterogeneous, multi-domain, multi-technology and multi-vendor network devices. In such a network(More)
With rising of Internet of Things (IoT) technology, billions of IoT devices and sensors interconnect and exchange large amount of data. Along with new IoT applications, there are many emerging important issues, such as device security and data protection. Recently, there are several global distributed denial-of-service (DDoS) attacks against home routers(More)
As the content-rich services which demand tremendous bandwidth proliferate, service providers must adapt to the trend quickly so as to meet not only the current demands but also the future needs of their customers. The hybrid fiber-copper deployment facilitates and complements Fiber-to-the-Home (FTTH) strategy in which optical fiber is gradually brought(More)
