pyPElib: a python Policy Engine library

Posted on 11/05/2012 by marc_sune

Policy management is one of the features a lot of applications need to care of and implement. Policy management and enforcement is indeed of particular interest in applications which offer fully automated IT services (IaaS, SaaS..). Provisioning, service instantiation or monitoring are just examples of application procedures where policy enforcement is highly desirable to be applied (when not a must).

The Ofelia Control Framework (OCF), as the automated testbed management tool being used in OFELIA FP7 and FIBRE FP7 projects, is no exception to that. As a result of the set of requirements comming from the OCF and within joint activities in OFELIA and FIBRE FP7 projects the pyPElib library has been developed, in order to have an homogeneous flexible policy enforcement code base.

In a nutshell pyPElib is a small python library to help programmers use the abstractions provided to apply rule-based policy enforcement in certain scopes of the application. Continue reading →

LTE & ETHERNET FUTURE OPPORTUNITIES

Posted on 03/05/2012 by victor_jimenez

Network convergence has been one of the hot topics in industrial and scientific conferences and congresses during the last years. In this sense, IP technologies seem to be the industry election for matching the application requirements and network operator’s constraints. For instance, IMS (IP Multimedia Subsystem) is a wide implemented platform which is been commercially adopted for service delivery.

Within the Long Term Evolution (LTE) adoption, Ethernet will provide an end-to-end convergence scenario as Ethernet will be the transmission layer for backhaul, aggregation, backbone and core networks. LTE provides a packet-based network for easy service deployment. This allows Telecom operators to easy match application and service requirements depending on the access technology.

Nevertheless, some improvements have to be done on Ethernet equipment in order to fully support 3rd Generation Partnership Project (3GPPP) and Metro Ethernet Forum (MEF) services, such as new mechanisms of synchronization to offer voice oriented channels with low latency requirements for end-to-end connections. Actually, synchronized Ethernet is a key technology in order to develop efficient data transport over LTE systems.

Labdoo – i2CAT collaboration

Posted on 27/04/2012 by Adrián Roselló

A few months ago we introduced you the collaboration agreement signed between Labdoo NGO and i2CAT. Both entities have been working together in order to break the existing digital divide and decrease the e-waste generation. After a set of meetings, the bases of the agreement were focused on two main action points i2CAT would work on. The first of them concerns extending Labdoo social network, which is the tool used by Labdoo’s collaborators to register the laptops they want to donate and/or the trips in which some of these laptops can be transported. Secondly, i2CAT would offer its infrastructures to create the “Barcelona Hub”, where the devices of this area would be stored and sanitized before their departure.

Going Agile in FP7 research projects

Posted on 23/04/2012 by Pau Minoves

(This post is a summary of the material I had the opportunity to present at EGI TF Lyon 2011, thanks to Marc-Elian, check it out)

Three years ago, I had the fantastic opportunity to study the confluence of Open Source community developments and large enterprise Agile setups at Ericsson. It was tough work but very fun. A year later, at i2CAT Foundation, we where kicking off the Mantychore FP7 project. Mantychore FP7 is a quite software intensive project, with ambitious NaaS objectives. Beyond that, the project also presented an interesting project management challenge itself: it was meant to be run as a consortium-wide SCRUM implementation. Later on, we could re-apply lessons learned to the RAISME Fp7 project, and learn a bunch of new ones. In this posts I’ll try to provide an overview of the lessons learned with the hope that it will helps others draft and run better and more successful research projects.

In order for NRENs (National Research and Education Networks) and operators to be able to deploy and operate the innovative NaaS offerings, an appropriate toolset has been created, OpenNaaS.

It has been envisioned as a multi-project software community that allows several stakeholders to contribute and benefit from a common NaaS software stack. The first objective of the OpenNaaS effort is enable NRENs to provide IP Network as a Service offerings to the research communities they serve.

On Network Management and Virtualisation

Posted on 30/03/2012 by Joan A. García-Espín
Share

Traditionally, network management has been developed around three main tasks: node management, node control (or configuration) and node monitoring. In a conceptual plane, this approach is still valid, but is clearly limited in scope: the bounded network domain (or simply ‘network’, in the sense of ‘administrative network domain’). However, being this so tightly related to the node and its technology, makes it difficult to focus on the network service provisioning and management. Things even go worse when considering inter-network services, which have to tackle inter-domain scenarios, user profiling and interfacing, and the distributed nature of present and future computing paradigms. It is precisely in the latter where, as a matter of fact and business, virtualisation has revolted IT service provisioning, materialising in Cloud Computing and making more evident that network management is not prepared for it.

Research projects in OFELIA

Posted on 23/03/2012 by Leonardo Bergesio

OFELIA facility has been open to the research community for free for some months already. First projects performed on it were mainly related with testing of the same facility, intra-federation of the individual islands, presentation to the FP7 FIBRE project’s partners in Brazil and so on.

But it seems time for more research projects is arriving. The i2CAT’s island in Barcelona was recently used by a student finishing the Telecommunications career at Polytechnic University of Catalonia (UPC) to prove and showcase his degree thesis on Power Aware Routing taking advantage of the SDN paradigm and OpenFlow technology.

WSO2 Stratos as a cloud platform

Posted on 16/03/2012 by albert_sole

The RAISME platform will be an open source platform and form the basis of an open-source community consisting of individuals, teams and organizations working to build a world-class and innovative open source mash-up platform that allow users to integrate services and build their desired work-flows with them. Users will be able to create analyses and different visualizations of the data, they will be able to create their own mashups through different services creating their own application. The RAISME Web site offers several ways that allow visitors/users to get involved and contribute to the community.

The RAISME core is based on WSO2 Stratos, so it has a key role in the project. First of all, we are going to see an explanation about what Stratos is and later the benefits it gives to the project.

On March 7th, Miguel Ponce de Leon, John Day and myself gave an overview of RINA, the motivations behind it and an status of the prototyping efforts at the University of Kaiserslautern, as part of a Ph.D course on “Future Network Architectures and Experimentation“. Miguel went through an introduction to RINA, similar to the one given by John at Barcelona, and John discussed about the misconceptions about layering in networks, exposing all the troubles these misconceptions have caused.
