In general a roaming broker enables roaming between two networks that do not have direct roaming relationships, by using an identity of a 3rd mobile network which does have roaming relations with both the visited and the home networks.

Starhome has build an IMS roaming broker that should be tested in various roaming scenarios. Since it bridges between different IMS networks, the compatibility with different IMS vendors is most important. The FT-PSC project (Federated Testbeds - Public Safety Communications) will provide few IMS test beds for conducting roaming tests. However it is highly recommended to increase the number of IMS test beds via external resources. Panlab exactly provides an access to a number of IMS labs maintained by different vendors. The Teagle tool facilitates the access to those labs by providing a single interface. Starhome has already started to investigate this tool and certainly would like to use it in the near future (2011).

On the fly, transcoding of video content or streams is becoming an increasing requirement for the media industry. This is mainly due to the increase in the number of different devices and platforms that can be used to play the video content as well as the numerous numbers of available codecs. Cloud computing is a natural way to do on the fly transcoding of these streams as it is possible to create a temporary computer farm needed to run these transcoding jobs without having to configure them manually. Therefore, depending on the size of these video files, the content can be delivered to any type of device, seamlessly. In this use case, the Panlab facility is used to transcode a high quality HD file used to stream live HD content to powerful computers to a more portable Mpeg 4 format that can be viewed on portable devices.

Multicast is becoming a ubiquitous technology however it still remains a challenge to deploy in some commercial networks. With offerings like IPTV becoming predominant Internet content it is required to see the impacts of multicast traffic on the network when having high latency environments such as international networks. However, configuring multicast capable networks across all these management domains and having the layer 1 connectivity on-demand, can be and lengthy process. That is the experimental international dynamic network called HPDMnet is being used in this experiment. Using this facility provides all the required substrate to do these low level multicast capable networks on-demand.

High Definition media is becoming important in the industry because of the needs in the movies and entertainment industry. Streaming uncompressed HD requires high bandwidth dedicated links. Such links are hard to obtain in multi-domain networks. In this use case different cinematic studios want to share and stream HD content over a high speed network. This use case is interesting to run via the Panlab facilities because these networks are not available everywhere. In this use case a customer can create a dynamic link on the fly within HPDMnet  network between to site. Then, the costumer can control uncompressed live HD streaming session by controlling Ultragrid software through Panlab tools (Teagle and VCT Tool).

Telefónica is opening some of its network functionalities to third party companies through a SDP (Service Delivery Platform) exposing a number of open APIs (SOAP and REST based) that can be used by companies and developers to build a new generation of telecommunication enabled applicationsand services. The TID SDPLabs is an environment meant for development and experimentation, which can be offered to third parties companies and developers around the world to develop their applications in an environment that offers real and simulated core telecommunication network capabilities. A third party company using the testbed TID SDPLabs will be able to make use of the following initial set of Telefónica’s network capabilities: Messaging, Contacts and Presence.

The Self-NET project has designed the architecture and the software for communication networks self-management based on the so called closed control loop or Monitor-Decide-Execute Cycle. The scope of this use case is to experiment on the improvement of QoS features (e.g., packet loss, delay, jitter)  using the Self-NET software for self-management over a live network environment and exploiting monitoring and configuration capabilities that different administrative domains provide (i.e. access network and service layer). The effectiveness and the feasibility of various parameters optimization of existing network protocols avoiding manual effort is also tested.

Web TV is a common application over the open Internet but enhancements of this service is contemplated thanks to additional components permitting to add Quality of Service. Typically real time video adapters and transcoders are under investigations to ensure more efficient delivery of the video streams over the internet. The adapters offer to resize the video content with respect to terminal characteristics. The transcoders permit to face different network bandwidth capabilities. The two components proposed here are the starting and ending points of the web TV service. The particular use case setup offers the possibility to perform tests upon:

• A Video on demand Service platform
• End users in a real «mobile operator» context.

In order for one to test an adaptive admission control and resource allocation algorithm, it is necessary to set up an appropriate testbed of a distributed web application like RUBiS benchmark, an auction site prototype modelled after eBay.com. It provides a virtualized distributed application that consists of three components, a web server, an application server, a database and its workload generator, which produces the appropriate requests. Furthermore it can be deployed in a virtualized environment using Xen server technology, which allows regulating system resources such as CPU usage and memory, and provides also a monitoring tool, Ganglia, that measures network metrics, such as round trip time and other statistics, and resource usage in virtual machines.

This use case illustrates the design steps via Teagle for an environment in which one can execute stress testing the Fraunhofer FOKUS open IMS core. It starts with configuring a low end server that is exposed to a specified traffic load via the SIPNuke tool. It obviously breaks under the load within a short time. Following the breakdown of the server the use case uses again Teagle to configure an environment that uses a higher capacity server in a cloud computing environment. This environment now survives the specified stress test.

A Federation Customer wants to test his own VOIP client application against operation conformance. Specifically the application’s performance regarding:

• Sound and recording capabilities and conformance
• Dialtone correct operation and conformance

The customer wants a simple setup of an Asterisk server and 2 VOIP user agents configured to use this VOIP server. Then he will test his VOIP user agent with the Asterisk service and the configured VOIP user agents. The Sound and recording capabilities and conformance will be accomplished through and ECHO VOIP service and the dialtone correct operation and conformance against a DTMF VOIP service. The customer’s test suite consists of the following two test cases:

1. From the customer VOIP application a call to an extension number ie #301 will be made towards the Asterisk server in order then to be redirected to the ECHO VOIP service.
2. From the customer VOIP application a call to an extension number ie #401 will be made towards the Asterisk server in order then to be redirected to the DTMF VOIP service.
