"Ultra Secure Networks in the Cloud.",
Marc Makkes, Leon Gommans, Cees de Laat, Robert Meijer (CIENA booth).
An ultra secure network environment, generated by a push of a button in a cloud, is demonstrated. The
secure network counters an attack, by changing its topology, moving itself to another cloud and by many other
mechanisms. The demonstration emphasizes that the cloud provides an ideal environment to create such secure
networks, as a service, by specialist companies or a whole industry. And since cyber security is important for
every organization, the demonstration shows that the future of the Internet is in the cloud.
"Multi-Domain High-Bandwidth SDN's", Ralph Koning, Cees de Laat (CIENA booth).
The collaboration between CIENA and the System and Network Engineering (SNE) group at the University of
Amsterdam will focus on two of the most pressing issues currently open in creating multi-domain high-bandwidth
SDNs (Software Defined Networks):
the use of standardized models, providing information about network topologies and network capabilities,
that can be exchanged between domains when setting up SDNs path flows across their boundaries;
the control and programmability of OpenFlow devices with more intuitive user interfaces, interfaces
capable of abstracting away the complexity of crossing domain boundaries,
At SC14 we show the first steps in this collaboration. Both UvA and Ciena recently purchased Exogeni racks
augmented with a more experimental setup. The racks are connected via the ANA-200 using the Ciena 8700
Packetwave Platform, this allows to connect three racks at Ciena StarLight and UvA using 100G forming the basis
for next generation SDN and cloud research.
"MultiCloud Application Scheduling via Open Cloud Exchange ( OCX)", Cosmin
Dumitru, Yuri Demchenko, Cees de Laat (SURF, CIENA and GEANT booth).
In this demonstration we present "Vampires", the user-centric data-aware cloud resource scheduler. The scheduler
allows users to deploy applications on multiple clouds. Users can define both performance and budget constraints
which are used by the scheduler to propose candidate resource configurations. In this way users do not
have to manually deal with creating the virtual infrastructure needed by their applications. Also in this
demonstration we show how "Vampires" can leverage dynamic dedicated links between cloud sites. For this feature
we use the GÉANT Open Cloud Exchange, a dedicated place for inter-connection and peering between cloud providers
and customers. In the demonstration we use a video transcoding application which is dynamically deployed over
"Topology Exchange and Path finding", Ralph Koning, S. Konstantaras, M.
Zivkovic, P. Grosso (UvA) and F. Iqbal, F. Kuipers (TU Delft).
The following demonstration implements the architecture of a novel system, responsible for exchanging topology
information in the NSI environment. This new system has been designed to work with multiple domains where their
topology knowledge is distributed in a hybrid approach. To achieve that, we define the main entities and their
functionalities and we propose the usage of NML scheme for describing network topologies. In addition, because
of the need to selectively discover shortest paths between STPs on domain level that satisfy certain
requirements, we developed the SPF (Selective Path Finding) algorithm for that purpose.
"Interconnecting Cloud Computing Clusters using Bandwidth on Demand Networks",
Daniel Romao, Ralph Koning (SURF booth).
Flexible cloud computing systems have a need of flexible network infrastructures. Currently deployed bandwidth
on demand systems, allow easy provisioning of multi-domain links, with the addition of the good bandwidth
management, making desirable its integration into cloud computing systems. In this demo, we use the ExoGENI rack
of the University of Amsterdam, for which we developed an extension to the ExoGENI's orchestration software
(ORCA) to allow automatic reservation and provision of links on the NSI bandwidth on demand system of the
AutoGOLE project. We use Flukes, the ExoGENI’s topology designer tool to create a virtual machine and a
bandwidth on demand network link connecting the virtual machine to a pinger service in our domain. After the
topology is created, we could verify the proper operation of the network link by performing connectivity tests
against the pinger service.
"Green Routing in OpenNaaS, Open Green Network as a Service", Daniel Romao,
Hao Zhu (SURF booth).
The traditional network management and service orchestration platform such as OpenNaaS and OpenStack, which
currently lack of support to power management for networks. We implemented energy-aware network monitoring and
routing capabilities in OpenNaaS. In this demo, we use OpenNaaS to monitor the power information of switches and
configured route in the OpenFlow network. Besides, we demonstrate to create a green routing path for a route
request from one host to another host. OpenNaaS server in the backend calculates a green routing path in terms
of power, cost and emission metrics based on measurement data and then configures flow forwarding rule in the
OpenFlow controllers to enable this green route.
"Valuing the greenness of NRENs", Daniel Romao, Paola Grosso, Arie Taal (SURF
A quality or performance measure reflecting the greenness of computer networks should be a function of multiple
aspects. Besides green aspects of network nodes, network owners also have to deal with aspects in the interest
of end-users. In this demo we propose a quality measure that values the greenness of the network among other
relevant aspects and that fluctuates with the design of the network, or as a consequence of different policies
applied. The measure is able to take multiple diverse aspects of a network node into account, like for instance
the utilized capacity, the PUE of the site where a node resides, the kind of energy the node is supplied with
(or $CO_2$-emission), the service cost of a node, etc..
The measure is applied to a real network, the Dutch NREN.
"CoCo - Multi-domain multi-point virtual private networks using
OpenFlow, Ronald van der Pol (SURFnet), Marijke Kaat (SURFnet), Bart Gijsen (TNO), Piotr Zuraniewski
(TNO), Daniel Cabaca Romao (UvA) (SURF booth).
The Community Connection (CoCo) service is a prototype for on-demand multi-domain multipoint L2/L3 VPN
instances. The prototype will be built on top of an OpenFlow infrastructure. End-users use a web portal to setup
CoCo instances. Typical users are research communities that form a closed user group and that want their
e-science resources (servers, VMs, laptops, storage, instruments, etc.) interconnected, but reachable for their
closed group only.
In this demo we will show how end-users can connect their OpenFlow equipment over different kinds of campus
network infrastructures to a CoCo domain, in order to participate in CoCo instances. We will also show how such
virtual network can be set-up, and highlight its advantages for the end-users.
