(13)        Parallel transmission mechanisms for in Data center networks

Parallel transmission mechanisms have appeared as valid candidates for both inter- and intra-data center networks. Firstly, it can support the emerging bandwidth intensive applications, such as HD live event streaming, bulk data transfer for scientific visualization etc. Secondly, the services supported by data centers nowadays assume the underlying network can provide fully support, while balancing its load based on the DNS redirect functions. However, the performance of the network can impact the quality of service experience provided by data centers, especially it impacts the current load balancing mechanisms. Utilizing parallel transmission can facilitate a better global load balancing with consideration of the job execution. 

In this seminar, the student is expected to studies some parallel transmission mechanisms for data center connections, with focus on the high performance applications and global load balancing. 

Der Vortrag erfolgt in deutscher oder englischer Sprache.

(14)        Recent developments in IP Traffic offloading over Optical WDM networks

Today a research challenge is the development of energy efficient networks which takes care of the knowledge, that the energy per bit transmission in the optical layer is much smaller than the energy needed in the IP layer, which mainly uses electrical devices. This demanded for shifting traffic from the recent IP layer to the optical WDM infrastructure. The seminar should give an overview of current developments. 

Der Vortrag erfolgt in deutscher oder englischer Sprache.

Seminarprogramm

         Netzwerk Virtualisierung

The term "Ossification of the Internet" is frequently used to describe the phenomenon that the deployment of innovative technologies and protocols is extremely retarded if not completely avoided due to the status quo of the current Internet architecture and the need for agreement among a huge number of organizations and companies with different or even contrary interests. Network virtualization was proposed as a solution in many different variations by the research community. Thereby, technologies like VLAN, VPN, or overlay networks are easy to implement / use, but they cannot solve the ossification problems in the core of the Internet. In this seminar, the student will study different approaches where multiple virtual wide area networks - implemented by virtual routers and virtual links - can share the same physical network.

Der Vortrag erfolgt in deutscher oder englischer Sprache.

         Grundlagen und aktuelle Tendenzen der Router Virtualisierung 

Durch die stetige Weiterentwicklung des Internets entsteht eine zunehmende Kluft zwischen klassischen und neuen Internet Protokollen. Eine Lösung bietet die Virtualisierung der Router in Netzwerk, so dass auf der gleichen Hardware, künftig Multicore Systeme, verschiedene Routing Protokolle parallel und isoliert arbeiten können. So ermöglichen programmierbare virtuelle Router den Test neuer Protokolle und Netzarchitekturen in bestehenden Infrastrukturen. 

Der Vortrag soll einen Überblick über hard- und softwaregestützte Virtualisierungstechniken geben und beispielhaft zeigen, wie Paketströme der virtuellen Router Instanzen voneinander isoliert werden können.

              What, how and why do we study about complex networks

This seminar gives a short introduction to the studies on complex networks: 1) what is the complex networks, 2) how we analyze the network structure and its evolution mechanism, and 3) why we should study it. 

Der Vortrag erfolgt in englischer Sprache.
