5th Swiss OpenStack User Group Meetup – at University of Zurich

5th Swiss OpenStack User Group

This fifth edition of the OpenStack CH User Group has been dedicated to the networking aspects of OpenStack but not only.
More then 40 people attended the meeting on 24-Oct. from 18.00 to 21.00 at the University of Zurich, Irchel campus
Sergio Maffioletti (GC3 project director,  University of Zurich) gave a short welcome before the presentations started.

The agenda included four talks, of about 30 minutes, in the following order:

OpenStack Networking Introduction by Yves Fauser, System Engineer VMware NSBU

The talk encompassed this topics: Traditional Networking – refresher, OpenStack integrated projects big picture, Why OpenStack Networking is called Neutron now, Networking before Neutron, Nova-Networking, Drawbacks of Nova-Networking that led to Neutron, OpenStack Networking with Neutron, Neutron Overview, Available Plugins, Neutron Demo and Neutron – State of the Nation.

NFV and Swisscom’s Openstack Architecture by Markus Brunner – Swisscom

Markus Brunner gave an introduction to Network Function Virtualization and how Swisscom sees how its implementation in the service chain could help to overcome the increasing traffic vs. decreasing customer fees dilemma, by offering value added networking virtual services (firewall, IP-TV, …).  Another major aspect is to minimize the number of different hardware boxes by using virtualized components running on cloud infrastructure and reduce vendor lock-in.

Mirantis Fuel and Monitoring and how it all powers the XIFI FI PPP Project by Federico Facca – Create-Net – Italy

Federico gave a presentation on the  XIFI project, XIFI architetcure and Infrastructure TOOLBOX which has the objectives of automating the installation of host operating system, hypervisor and OpenStack software through the Preboot eXecution Environment (PXE). The TOOLBOX also defines and selects a deployment model among the ones available and discovers the servers where to install the software.
XIFI federation allows to specify a “role” (controller, storage, compute etc) for each server and makes set up & network configuration (vlan etc), supports registration of the infrastructure into the federation and finally tests the deployment so to verify that everything has been installed correctly.

Ceph Storage in OpenStack by Jens-Christian Fischer SWITCH

The presentation gave interesting hints on Ceph Design Goals, Ceph Storage options, Ceph architecture, CRUSH Algorithm, Monitor – MON and Metadata Server MDS.  Jens-Christian then concluded with information about OpenStack at SWITCH and Test Cluster.

Q&A session


Future trends and technologies in Mobile and Internet communications @ CFIC 2013

Future trends of Mobile and Internet Communications are revealed at the Conference on Future Internet Communications 2013 in Coimbra, Portugal. The many different speeches and talks show that Cloud Computing could play a major role in future Mobile Communication networks.

Alexander Sayenko explains future trends in 3GPP standardization.

Alexander Sayenko explains future trends in 3GPP standardization.

The first keynote speech of the Conference was held by Alexander Sayenko, researcher at Nokia Siemens Networks, where he is responsible for standardization activities of the 3GPP-specification. In his keynote speech he presented the new HetNet multicarrier solution for the enhancement of current mobile communication traffic. While mobile communication traffic is expected to grow exponentially for the next decade, very diverse requirements concerning reliability and mobility of IT services offer a major challenge to the telecommunication industry. In order to be able to handle the growing mobile traffic, widening the available radio spectrum breadth and enhancing spectral efficiency as well as offloading of communication data to clusters of mobile base stations should enhance capacity of current mobile networks. HetNet offers a solution to enhance the radio spectrum and use the radio spectrum more efficiently by meshing up multiple heterogenous access networks. The future trend in mobile communication is going towards managing heterogeneous network infrastructures since the new standards like LTE and HSPA+ are still not used broadly and will not likely replace older technologies as fast as expected by the mobile end users. While the number of mobile devices and applications grows rapidly, changes in the infrastructure of mobile communication providers are performed much more slowly. New standards in mobile communications are a necessity in order to avoid a situation where the network infrastructure becomes a bottleneck to the mobile communication market.

Bottleneck: low efficiency of current access networks

The message is clear: mobile networks should be used more efficiently. An efficiency gain could be provided by the use of Cloud Computing for mobile networks. Andreas Kassler, researcher at Karlstads University in Sweden, showed CloudMAC – a new approach on how to allow location-independent routing of mobile devices in Wireless networks without introducing additional routing protocol overhead like e. g. in the Mobile IP protocol. The solution is to source the routing logic from Wireless Termination Endpoints into a virtualized infrastructure like e. g. an OpenStack cloud. Such an approach shows that Cloud Computing could become very important for the development of more efficient mobile networks. Therefore projects like e. g. the Mobile Cloud Network at ICCLab can make mobile communication ready for the challenges of the next decade.

ICCLab: enhance Quality of Cloud Services

The ICCLab had also a chance to present the benefits of Cloud Services for future Internet communications. Konstantin Benz, researcher at ICCLab, presented different technologies for OpenStack which should enable High Availability. He also showed how the Chaos Monkey tool could be transformed in a test framework which can add HA readiness of OpenStack architectures. The ongoing research about Cloud Automation, Cloud Dependability, Cloud Interoperability, Cloud Monitoring and Cloud Performance at ICCLab improves the overall quality of Cloud Computing as a service. Therefore Cloud Computing offered by ICCLab is able
