Abstract

Wireless technology advances over the last few years have led to a wide use of WPAN, WLAN and WMAN. WiFi and Bluetooth technologies have been widely used in recent years (homes, enterprises, university campus, indoors cars …). While the first technology is widely used to connect mobile gadgets the second is widely used to build spontaneous wireless networks and to access Internet. The convergence between Telecommunication and Computer Communication has led to powerful multimedia communication frameworks to implement Real Time Multimedia services. A plethora of mobile terminal devices like mobile phones every day help their users to use multimedia services. These devices include powered sensors that allow technicians to implement rich multimedia services.

Recently very important advances have been produced in the physical level including MIMO technology, Ultra Wide Band, Cognitive Radio... These advances improve the radio signal received by terminals but they do not avoid the terminals loss coverage in certain regions where there is strong radio pollution or simply faults of coverage. As a result, real time communications can be subject to disruptions during an important time interval - a serious problem for real time communications or a user headache for firm real time multimedia communication.

The presentation will include: an analysis of the present convergence between Multimedia Computer Communications and Telecommunications in the wireless world; Reviewing of interesting QoS properties of wireless technologies; Challenges of wireless real time multimedia communications; Different approaches to solve the sudden loss of coverage for multimedia real time communication; and future advances of wireless networks and services. The assistants will be invited to experiments with their own WiFi mobile devices just in case.

Abstract

This tutorial gives an introduction to the NetFPGA platform and how it can be used.  It demonstrates the use of the reference router to dynamically re-­‐route traffic using PW-­‐OSPF with streaming video traffic.  It is also show how existing designs can be extended to experiment with buffer sizes.

From the basics of NetFPGA and the networking review needed to get into the field, the tutorial provides a general overview of this community-­‐supported platform that has been successfully used for networking research and teaching around the world.

No knowledge of Verilog/VHDL is required to attend the tutorial, although knowledge of these languages is needed to program NetFPGA.

Introduction to the Subject

The NetFPGA is and open platform enabling researchers and instructors to build high-­‐ speed, hardware-­‐accelerated networking systems. The platform can be used in the classroom to teach students how to build Ethernet switches and Internet Prototcol (IP) routers using hardware rather than software.
The platform can be used by researchers to prototype advanced services for next-­‐generation networks. By using Field  Programmable Gate Arrays (FPGAs), the NetFPGA enables new types of packet routing circuits to be implemented and detailed  measurements of network traffic to be obtained.

Abstract

WebRTC is an emerging technology which provides state-of-the-art native RTC (Real Time Communications) to web browsers and will be a very important piece for telecommunications in the coming years. By adding a signaling protocol for establishing media sessions, a browser becomes a full RTC communication device making the WWW the biggest RTC network that have ever existed.

Session Initiation Protocol (SIP) is a mature and widely used signaling protocol for real time session management. A recent IETF specification enables the use of SIP in the WWW by using WebSocket as a signaling transport: "The WebSocket Protocol as a Transport for the Session Initiation Protocol (SIP)". This new SIP specification facilitates the communication between web browsers and existing SIP devices and makes possible to accommodate web browses into existing SIP infrastructures.

Biography of the lecturer

Abstract

A major trend in today's Internet applications is the use of multi-tenant datacenters. Such infrastructures offer a proper environment for elastic growth by employing a simple pay-per-use model. However, the use of shared network resources on datacenters brings major challenges, such as performance unpredictability, new security concerns and poor performance of conventional Internet protocols. In this tutorial, I’ll present an overview of multi-tenant datacenter networks, including discovered limitations and how recent proposals seek to address them on each layer. Issues include approaches to guarantee minimum bandwidth for individual or groups of tenants, performance predictability, proportional division of network resources and security issues. The tutorial will close with open challenges and research directions.
