Keynote Speech K1: 5G backhaul: A Challenging Scenario for Time-Sensitive Switching
Abstract: A number of new requirements from stringent communication scenarios requiring high bitrates close to link capacity, low latency or synchronous operation has recently triggered initiatives to enhance switching and transmission capabilities of packet switches once more. This is the case of the IEEE802.1 Time Sensitive Networking (TSN) Task Group, whose focus is time-synchronized low latency streaming services through 802 networks. More recently (October 2015), a new IETF working group has been formed in the Routing Area named “Deterministic Networking” (detnet), which shows the interest in designing layer 3 systems interworking with TSN-capable layer-2 switches. This interest is not just due to streaming: the number of scenarios where Ethernet or IP-MPLS routers could be applied as a cost-effective technology to replace circuits keeps growing as carriers demand more complex transport capabilities. This work reviews standards and challenges behind the design of a cost-effective access and metro switching technology capable of integrating front-haul and back-haul traffic for 5G, a problem being addressed by the XHAUL European research project.

Keynote Speech K4: The Relevance of Green Revolution to Information and Communication Technologies as well as Big Data
Abstract: Although the term of green has been often used to refer to energy consumption reduction or energy efficiency by many people and literatures, green actually should refer to environmental sustainability in more general senses. Environmental sustainability issues have been important topics for recent years, which has impacted and will further impacted individuals, enterprises, governments, and societies. Environmental sustainability is not simply regarding reducing the amount of waste or using less energy, but relevant to developing processes leading to completely sustainable human society in the future. The long term consequences of this serious issue have not yet been fully forecasted, but it has been generally accepted in many communities that immediate responses are necessary. The term of information and communications technologies (ICT) indicates the integration and convergence of two rapid growing fields, computing and communications. ICT are a big umbrella covering many topics and issues relevant to the modern times. Big data is a broad term for such large or complex ata sets that traditional data processing applications are inadequate. Big data are not just about the realization of information explosion, but about technologies that ensure value can be generated from the massive of data. This talk would discuss and explore the relevance of the modern green revolutions to ICT as well as big data issues. This talk also would talk about the features, benefits, challenges, and limitations of green revolution. The discussions would address the environmental sustainability issues, approaches, practices, and challenges for ICT as well as big data, and stress the interdisciplinary natures of relevant topics.

Keynote Speech K3: Networking in the Big Data Era
Abstract: The volume of data being produced today is increasing to astronomical levels; such huge volumes of data are currently known as Big Data. Indeed, the recent introduction of smartphones and tablets, together with the widespread use of social networks, has even turned individuals into active sources of data production. Facebook receives approximately 30 billion uploads every month, implying a daily generation of 10 terabytes (TB) of data, while Twitter generates more than 7 TB of data every single day. Equally important is the information generated by the use of 5 billion mobile phones worldwide. These realms of data must also be processed to transform them into useful information and discover hidden inter-data relationships. Today, we are on the verge of a new era, and advancement will depend crucially on our capacity for effective and efficient communication of such enormous quantities of data. In consonance, in this talk, I will discuss the major challenges for networking technology in the provisioning of communication in the emerging era of Big Data.

Keynote Speech K2: New techniques for the design and implementation of high power microwave amplifiers for Wimax applications
Abstract: In high power applications at microwave frequencies, accuracy of measurements and CAD tools are critical in order to reach respectable performances. By using an RFIC LDMOS device we demonstrated that we can reach power and efficiency requirements for 3.5GHz Wimax applications. One of the critical aspects is the design of the nonlinear model for this kind of device. Several load pull measurements performed on an implemented demoboard will be shown as evidence of the performance of the device. In this work we will show results by using a 10MHz Wimax signal, biasing the device for class AB. For final stage applications and at +37dBm average output power from 3.4 to 3.6 GHz, we can reach an efficiency around 15 percent with an associated error vector magnitude at -33 dB. The gain can reach 25 dB across the band. Another feature of this design is that by simply optimizing the bias point, and slightly fine tunnning the PCB and using the same WiMAX signal as before, we can show that for +27 dBm output power, the ACP values are better than -52 dBc, while the EVM values are better than -36 dB. This feature makes this design suitable and flexible enough for these two configurations: driver and power stage.
