Network management graphical user interface

Abstract: A method is provided for graphically depicting detailed state and status information for network objects, particularly network objects forming part of a telecommunications network. A graphical representation of a network is displayed in which a basic icon is displayed for each network object. More commonly occurring state and status combinations are conveyed by imparting attributes to the basic icons such as dashed, solid, or three-dimensional outlines. Less commonly occurring state and status combinations are conveyed by attaching modifier icons to the basic icons. The method is particularly suited to providing a detailed visual representation of the states and statuses included in the OSI standard.

Communicating data through a network so as to ensure quality of service

Abstract: Techniques for communicating data through a network so as to satisfy various Quality Of Service (“QOS”) levels are described. The QOS levels may be selected based on a determined type of the data or the data communication, such as by a network manager after the data communication is registered, and QOS communication parameters are selected for the data communication to ensure that the QOS levels are achieved. Other techniques may also be used to ensure that a selected QOS level is achieved, including selecting an appropriate path through the network, controlling other data communications that use some or all of the selected path, and/or enabling preemption of such other data communications. QOS levels that are actually achieved may also be monitored, and the QOS communication parameters and/or path for a data communication may be dynamically modified based on differences between actual achieved QOS levels and desired QOS levels.

Snmp, Snmpv2, and Cmip: The Practical Guide to Network-Management Standards

Abstract: A comprehensive introduction to network-management standards. Part I is a survey of network-management technology and techniques. Part II presents the SNMP family of standards, including SNMP itself, secure SNMP, and SNMPv2. An important enhancement of SNMP, known as RMON (remote monitoring) is also

A Declarative and Expressive Approach to Control Forwarding Paths in Carrier-Grade Networks

Abstract: SDN simplifies network management by relying on declarativity (high-level interface) and expressiveness (network flexibility). We propose a solution to support those features while preserving high robustness and scalability as needed in carrier-grade networks. Our solution is based on (i) a two-layer architecture separating connectivity and optimization tasks; and (ii) a centralized optimizer called framework, which translates high-level goals expressed almost in natural language into compliant network configurations. Our evaluation on real and synthetic topologies shows that framework improves the state of the art by (i) achieving better trade-offs for classic goals covered by previous works, (ii) supporting a larger set of goals (refined traffic engineering and service chaining), and (iii) optimizing large ISP networks in few seconds. We also quantify the gains of our implementation, running Segment Routing on top of IS-IS, over possible alternatives (RSVP-TE and OpenFlow).

Soft-WSN: Software-Defined WSN Management System for IoT Applications

Abstract: In this paper, we propose a software-defined wireless sensor network architecture ( Soft-WSN )—an effort to support application-aware service provisioning in Internet of Things (IoT). Detailed architecture of the proposed system is presented involving the application, control, and infrastructure layers to enable software-defined networking (SDN) in IoT. We design a software-defined controller, which includes two management policies—device management and network management. Device management facilitates users to control their devices in the network. To enable device control mechanisms, we investigate three scheduling issues in a sensor node—sensing task, sensing delay, and active sleep. On the other hand, the topology of the network is controlled by the network management policies, which can be modified in run time to deal with dynamic requirements of IoT. Furthermore, the proposed scheme is implemented in a real hardware platform without changing the underlying sensor networking concepts, so that existing sensor devices can be seamlessly integrated. Therefore, in contrast to the existing SDN solutions for WSNs, the proposed system, Soft-WSN , focuses on both device management and topology management to meet run-time application-specific requirements of IoT, while enhancing flexibility and simplicity of WSN management. Experimental results on a real hardware-based test bed indicate that the proposed scheme is beneficial to meet real-time application-specific requirements of IoT, while ensuring significant improvements on network performance over the traditional approaches.
