TL;DR: The robustness property guarantees that, starting from an arbitrary configuration, after one asynchronous round, the network is partitioned into clusters and stays partitioned during the convergence phase toward a legitimate configuration where the clusters verify the ''ad hoc clustering properties''.

TL;DR: This paper introduces a novel SDN/OpenFlow-based architecture and control plane framework tailored for MCC-based systems and more specifically for FMC- based systems where mobile nodes and network services are subject to constraints of movements and migrations.
Abstract: Future 5G mobile network architecture is expected to offer capacities to accommodate the inexorable rise in mobile data traffic and to meet further stringent latency and reliability requirements to support diverse high data rate applications and services. Mobile cloud computing (MCC) in 5G has emerged as a key paradigm, promising to augment the capability of mobile devices through provisioning of computational resources on demand, and enabling resource-constrained mobile devices to offload their processing and storage requirements to the cloud infrastructure. Follow-me cloud (FMC), in turn, has emerged as a concept that allows seamless migration of services according to the corresponding users mobility. Meanwhile, software-defined networking (SDN) is a new paradigm that permits the decoupling of the control and data planes of traditional networks and provides programmability and flexibility, allowing the network to dynamically adapt to change traffic patterns and user demands. While the SDN implementations are gaining momentum, the control plane is still suffering from scalability and performance concerns for a very large network. In this paper, we address these scalability and performance issues in the context of 5G mobile networks by introducing a novel SDN/OpenFlow-based architecture and control plane framework tailored for MCC-based systems and more specifically for FMC-based systems where mobile nodes and network services are subject to constraints of movements and migrations. Contrary to a centralized approach with a single SDN controller, our approach permits the distribution of the SDN/OpenFlow control plane on a two-level hierarchical architecture: a first level with a Global FMC Controller (G-FMCC), and a second level with several Local FMC Controllers (L-FMCCs). Thanks to our control plane framework and Network Function Virtualization (NFV) concept, the L-FMCCs are deployed on-demand, where and when needed, depending on the global system load. Results obtained via analysis show that our solution ensures more efficient management of control plane, performance maintaining, and network resources preservation.

TL;DR: In this paper, a system for updating a memory storing configuration information of a network element is described, where the network manager receives selected configuration information from the network element to update a selected part of the memory if a received state variable does not match a stored state variable.
Abstract: A system for updating a memory storing configuration information of a network element includes a network element and a network manager coupled to the network element using a communication network. The network manager receives selected configuration information from the network element to update a selected part of the memory if a received state variable does not match a stored state variable.

TL;DR: In this paper, the authors propose a network management module (NMM) that is configured to receive an indication of a set of network policies to apply to the security domain, automatically determine a subset of policy enforcement points (PEPs) of the set of PEPs are required to enforce the network policies based on physical network topology information readable by the NMM that includes information about the location of the endpoint computing resources.
Abstract: An example network system includes a plurality of endpoint computing resources, a business policy graph of a network that includes a set of the plurality of endpoint computing resources configured as a security domain, a set of policy enforcement points (“PEPs”) configured to enforce network policies, and a network management module (“NMM”). The NMM is configured to receive an indication of a set of network policies to apply to the security domain, automatically determine a subset of PEPs of the set of PEPs are required to enforce the set of network policies based on physical network topology information readable by the NMM that includes information about the location of the endpoint computing resources and the set of PEPs within the network, and apply the network policies to the subset of PEPs in order to enforce the network policies against the set of endpoint computing resources of the security domain.

TL;DR: In this article, a technique suitable for configuration management of a network for which the number of logical network layers can be set is presented, where a network management apparatus receives an address definition information file defining logical hierarchical structure of an IPv6 network 20, from an operator through a definition information reception unit 103.
Abstract: The present invention provides a technique suitable for configuration management of a network for which the number of logical network layers can be set. A network management apparatus 10 receives an address definition information file defining logical hierarchical structure of an IPv6 network 20 , from an operator through a definition information reception unit 103 . A configuration analysis unit 104 generates management tables defining hierarchical relationships of logical networks, based on the address definition information file and IP addresses collected respectively by an information collection unit 102 from network elements belonging to the IPv6 network 20 , and registers the management tables into a management DB unit 101.
