Energy-efficient core networks
2012 16th International Conference on Optical Network Design and Modelling (ONDM), 2012In this paper, we optimize core networks to minimize the embodied energy and the operational energy and introduce two measures for energy minimization in core content distribution networks: data compression in optical networks and locality in P2P networks.

Programmable Mobile Core Network
2014 IEEE Symposium on Computers and Communications (ISCC), 2014Mobile operators are recently forced to provide higher bandwidth connections to mobile users in order to manage fierce competition. As a result, operators started deployment of Long Term Evolution (LTE)/ Evolved Packet core (EPC) network. However, current LTE/EPC architecture, functions and protocols are not optimized.

Journal of Optical Communications and Networking, 2013
The Internet core today is completely based on IP routers. Circuits are only used to provide static point-to-point optical links between routers. As others have recognized, current practice makes it hard to take advantage of very high-speed, low-power optical circuit switches in the core.

Planning of UMTS core networks
The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003Building new UMTS (Universal Mobile Telecommunication Systems) based networks, seems to be on time. Nowadays the UMTS network design related problems are moving to the interconnection of radio network controllers (RNC), placement of media gateways (MGw) and planning of the core network topology.

Core Percolation in Interdependent Networks
IEEE Transactions on Network Science and Engineering, 2019Core percolation, as a fundamental structural transition resulting from preserving core nodes in the network, is crucial in the network controllability and robustness. Prior art has investigated single, non-interacting complex networks where core structure plays an important role in ensuring the network robustness.

Structure and Network in the YouTube Core
Proceedings of the 41st Annual Hawaii International Conference on System Sciences (HICSS 2008), 2008In this paper, we present results of an empirical investigation into the social structure of YouTube, addressing friend relations and their correlation with tags applied to uploaded videos. Results indicate that YouTube producers are strongly linked to others producing similar content.

On the core of network synthesis games
Mathematical Programming, 1991A formulation is proposed for unifying network design cooperative games which shows that not only the minimum cost spanning tree game satisfies the assumptions of Owen's linear production game. Moreover, since the suggested formulation is polynomial in size, a vector in the core can be computed efficiently by solving a single linear program. Generally,

Inferring Spammers in the Network Core
2009Despite a large amount of effort devoted in the past years trying to limit unsolicited mail, spam is still a major global concern. Content-analysis techniques and blacklists, the most popular methods used to identify and block spam, are beginning to lose their edge in the battle.

Stable Community Cores in Complex Networks
2013Complex networks are generally composed of dense sub-networks called communities. Many algorithms have been proposed to automatically detect such communities. However, they are often unstable and behave nondeterministically. We propose here to use this non-determinism in order to compute groups of nodes on which community detection algorithms agree ...

Network evolution and the impact in core networks
36th European Conference and Exhibition on Optical Communication, 2010The talk will present the projected evolution of networks and their impact on core networks. From FFTH deployment to the Internet of Things or Information Centric Networks, current trends tell us that future networks will be different from today. How this will impact optical core networks and what the role of optics will be in these networks are ...
