TL;DR: The gateway for SNMP/OSI management enables that an SNMP manager manages an OSI management agent, by using a basic conversion of a management operation and a management information between SNMP and CMIP.
Abstract: The gateway apparatus for SNMP/OSI management enables that an SNMP manager manages an OSI management agent, by using a basic conversion of a management operation and a management information between SNMP and CMIP and by using a cache, a replica and a link object.

TL;DR: This paper proposes StateSec, a novel approach based on in-switch processing capabilities to detect and mitigate DDoS attacks, and implemented StateSec and compared it with a state-of-the-art approach to monitor traffic in SDN.
Abstract: Software-Defined Networking (SDN) allows for fast reactions to security threats by dynamically enforcing simple forwarding rules as counter-measures. However, in classic SDN all the intelligence resides at the controller, with the switches only capable of performing stateless forwarding as ruled by the controller. It follows that the controller, in addition to network management and control duties, must collect and process any piece of information required to take advanced (stateful) forwarding decisions. This threatens both to overload the controller and to congest the control channel. On the other hand, stateful SDN represents a new concept, developed both to improve reactivity and to offload the controller and the control channel by delegating local treatments to the switches. In this paper, we adopt this stateful paradigm to protect end-hosts from Distributed Denial of Service (DDoS). We propose StateSec, a novel approach based on in-switch processing capabilities to detect and mitigate DDoS attacks. StateSec monitors packets matching configurable traffic features (e.g., IP src/dst, port src/dst) without resorting to the controller. By feeding an entropy-based algorithm with such monitoring features, StateSec detects and mitigates several threats such as (D)DoS and port scans with high accuracy. We implemented StateSec and compared it with a state-of-the-art approach to monitor traffic in SDN. We show that StateSec is more efficient: it achieves very accurate detection levels, limiting at the same time the control plane overhead.

TL;DR: This article presents a comprehensive study of 5G networks architecture, technologies, challenges, and possible solutions based on recent advances in technology and research.
Abstract: Future 5G networks are expected to have the capabilities of providing extremely high data rates, seamless coverage, massive number of connected devices, low latency, etc., in order to support the internet of things era. The dynamic performance of 5G networks is a key feature for controlling the dense and rapidly changing communication environment. Technical issues such as limited frequency resources, interference, energy consumption, and network management are the main challenges facing 5G networks. This article presents a comprehensive study of 5G networks architecture, technologies, challenges, and possible solutions based on recent advances in technology and research.

TL;DR: An efficient, lightweight infrastructure based on mobile agents is described, which is shown to outperform SNMP both in terms of the polling response time and bandwidth consumption when considering data intensive operations.
Abstract: The use of mobile agent technology to distribute and delegate management tasks promises to overcome the scalability and flexibility limitations of the centralised network management paradigm. An efficient, lightweight infrastructure based on mobile agents is described, which addresses these issues by distributing management operations amongst managed devices and hence reduces the processing load and bandwidth usage. A mobile agent generator that facilitates the creation of new mobile agents for additional services is also presented. Our infrastructure is shown to outperform SNMP both in terms of the polling response time and bandwidth consumption when considering data intensive operations.

TL;DR: In this article, a method of managing Wi-Fi access points using a WiFi network manager is described. But the authors focus on the measurement data received from a plurality of access points via a control interface.
Abstract: A method of managing Wi-Fi access points using a Wi-Fi network manager is disclosed. Measurement data is received from a plurality of Wi-Fi access points via a control interface. Optimized adjustments to one or more Wi-Fi parameters associated with one or more of the plurality of access points are searched based at least in part on a set of network optimization goals and the measurement data received from the plurality of access points. At least some of the optimized adjustments to the one or more Wi-Fi parameters are transmitted to the one or more of the plurality of access points using the control interface.
