The Generealised Architecture for Dynamic Infrastructure Services (GEYSERS) project has reached its end. In January 2010 we started an innovative and challenging project. GEYSERS’ vision was to qualify optical infrastructure providers and network operators with a new architecture, in order to enhance their traditional business operations.
This vision was driven by its architecture that addressed optical Cloud infrastructures. The challenges faced can be summarized as:
- Network and IT resource abstraction.
- Virtual IT and network infrastructure composition.
- Integrated IT and network service provisioning.
- Energy efficiency.
- Scalability and dynamic re-planning of virtual infrastructures.
To address these challenges , we proposed a novel architecture that adopted the concepts of Infrastructure as a Service (IaaS) and service oriented networking to enable infrastructure operators to offer net network and IT converged services. The architecture is composed by the following elements:
- Logical Infrastructure Composition Layer (LICL), that is the layer responsible of abstracting and partitioning the underlying physical substrate. The LICL acsts as a middleware on top of the physical infrastructure and composes virtual infrastructures that are offered as a service towards the virtual infrastructure operators.
- Enhanced Network Control Plane (NCP+), that is based on the Generalized Multi-Protocol Label Switching (GMPLS) and Path Computation Element (PCE) architecture and includes a set of extensions both in terms of architectural elements and protocol procedures in order to meet the emerging requirements.
- Service Middleware Layer (SML), which is the convergence layer utilized in order to coordinate management of IT resources belonging to an aggregate service.
The project has represented 39 months of continuous challenges. The consortium was composed of network operators, manufacturers, SMEs, software editors, universities, and research entities. We have built several pieces of software that were demonstrated in the final demonstrators:
- Virtual Infrastructures for the VIO
- Anycast services over Virtual Infrastructures
- Dynamic Cloud-based Enterprise Information System Scaling
- Advanced Virtual Infrastructure and Service Management – Dynamic Re-planning
Although the project ended, most of the open-source software created is nowadays available at sourceforge; and there are new research projects where some of the partners involved in the project are still collaborating in order to strengthen the work produced in GEYSERS.
