TSI-100102-2013-85 project co-funded by the Ministry of Industry, Energy and Tourism within the Strategic Action on Economy and Digital Society of the National Plan for Scientific Research, Development and Technological Innovation.
The SIGMONA project, “SDN Concept in Generalized Mobile Network Architectures”, will study network architectures and functions for evolution of the LTE/EPC (3GPP) mobile networks. The main focus is on the network, although and end-to-end system approach, including the LTE radio system, will be taken. The project will apply the latest networking and computing technologies and architectures onto the LTE/EPC mobile network.
The SDN concept enables separation of data forwarding plane from the control planes. The SDN-enabled switches, routers and gateways are controlled through an SDN controller/Network operating system, and are seen as virtual resources. The control plane of the mobile networking elements can be deployed onto an operator cloud for computing. Applications provided by an operator, such and Content Delivery Networks (CDN), Voice over IP (VoIP) and IP-TV can also be deployed onto the cloud.
The concept of a Software Defined Mobile Network would change the network architecture of the current LTE (3GPP) networks. It will also open up new opportunities for traffic, resource and mobility management, as well as impose new challenges on network security. Network virtualization solutions in the mobile transport networks, as well as effects on the network monitoring and network management solutions will be relevant, too. It is also foreseen that the investments on the network and operational costs would change. Furthermore, the value chain may change and new business models emerge. All these aspects are meant to be studied in SIGMONA project.
The main objective of the project is on the application of the latest networking and computing technologies and architectures onto the LTE/EPC mobile broadband (3GPP) network.
The project aims at evaluation, specification and validation of a Software Defined Mobile Network concept which applies software defined networking (SDN), network virtualization and cloud computing onto the LTE mobile networks. The project will provide an insight into the feasibility and opportunities of such network concepts, as well as evaluate the limits of performance and scalability of the new technologies applied on mobile broadband networks. Use cases, such as content delivery will be considered. It will also outline the impact onto cost of network, value chain and business models. Impact onto the model of open interfaces and the role of standards and related bodies will also be defined.
