SDN Concept in Generalized Mobile Network Architectures


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 project aims at evaluation, specification and validation of a Software Defined Mobile Network concept designed onto the software defined networking (SDN), network virtualization and cloud computing principles. 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.

New opportunities for traffic, resource and mobility management will be studied. New challenges on network security and solutions for those will be addressed. Network virtualization solutions in the mobile transport networks, as well as effects on the network monitoring and network management solutions are relevant, too. Use cases, such as content delivery will be considered. It is also foreseen that the investments on the network and operational costs would change, hence the project will also outline the impact onto cost of network, value chain and business models. The model of open interfaces, the role of standards and related bodies will also be described.
