Network Management
Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining quality of service. Network management software is used by network administrators to help perform these functions. Technologies A small number of accessory methods exist to support network and network device management. Network management allows IT professionals to monitor network components within large network area. Access methods include the SNMP, command-line interface (CLI), custom XML, CMIP, Windows Management Instrumentation (WMI), Transaction Language 1 (TL1), CORBA, NETCONF, RESTCONF and the Java Management Extensions (JMX). Schemas include the Structure of Management Information (SMI), YANG, WBEM, the Common Information Model ( CIM Schema), and MTOSI amongst others. Value Effective network management can provide positive strategic impacts. For ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
System Administrator
An IT administrator, system administrator, sysadmin, or admin is a person who is responsible for the upkeep, configuration, and reliable operation of computer systems, especially multi-user computers, such as Server (computing), servers. The system administrator seeks to ensure that the uptime, Computer performance, performance, System resource, resources, and Computer security, security of the computers they manage meet the needs of the User (computing), users, without exceeding a set budget when doing so. To meet these needs, a system administrator may acquire, install, or upgrade computer components and software; provide routine automation; maintain security policies; troubleshoot; train or supervise staff; or offer technical support for projects. Related fields Many organizations staff offer jobs related to system administration. In a larger company, these may all be separate positions within a computer support or Information Services (IS) department. In a smaller group ...

Web-Based Enterprise Management
In computing, Web-Based Enterprise Management (WBEM) comprises a set of systems-management technologies developed to unify the management of distributed computing environments. The WBEM initiative, initially sponsored in 1996 by BMC Software, Cisco Systems, Compaq Computer, Intel, and Microsoft, is now widely adopted. WBEM is based on Internet standards and Distributed Management Task Force (DMTF) open standards: * Common Information Model (CIM) infrastructure and schema ** CIM-XML ** CIM operations over HTTP * WS-Management for web services *CIM Operations over RESTful Services Although the name labels WBEM as "web-based", it is not necessarily dependent on any particular user interface (see below). Other systems-management approaches include remote shells, proprietary solutions and IETF standardized network-management architectures like the SNMP and Netconf. Features WBEM allows the management of any element in a standard and inter-operable manner. WBEM provides the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Traffic Measurement
In computer networks, network traffic measurement is the process of measuring the amount and type of traffic on a particular network. This is especially important with regard to effective bandwidth management. Techniques Network performance could be measured using either active or passive techniques. Active techniques (e.g. Iperf) are more intrusive but are arguably more accurate. Passive techniques have less network overhead and hence can run in the background to be used to trigger network management actions. Measurement studies A range of studies have been performed from various points on the Internet. The AMS-IX (Amsterdam Internet Exchange) is one of the world's largest Internet exchanges. It produces a constant supply of simple Internet statistics. There are also numerous academic studies that have produced a range of measurement studies on frame size distributions, TCP/UDP ratios and TCP/IP options. Tools Various software tools are available to measure network traffic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Monitoring
Network monitoring is the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator (via email, SMS or other alarms) in case of outages or other trouble. Network monitoring is part of network management. Details While an intrusion detection system monitors a network threats from the outside, a network monitoring system monitors the network for problems caused by overloaded or crashed servers, network connections or other devices. For example, to determine the status of a web server, monitoring software may periodically send an HTTP request to fetch a page. For email servers, a test message might be sent through SMTP and retrieved by IMAP or POP3. Commonly measured metrics are response time, availability and uptime, although both consistency and reliability metrics are starting to gain popularity. The widespread addition of WAN optimization devices is having an adverse effect on most network monitorin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network And Service Management Taxonomy
The network and service management taxonomy serves as a classification system for research on the management of computer networks and the services provided by computer networks. The taxonomy has been created and is being maintained by a joint effort of the Flamingo FP7 Project and the Committee of Network Operations and Management (CNOM) of the Communications Society (COMSOC) of the Institute of Electrical and Electronics Engineers (IEEE) and the Working Group 6.6 of the International Federation of Information Processing (IFIP). The taxonomy is organized into seven categories. The first four categories identify what kind of network/service/business aspect is being managed and which functional areas are covered. The remaining three categories identify which management paradigms, technologies, and methods are used. Category #1: Network Management The first category called "Network Management" addresses the following question: What kind of network is being managed? * IP network ...

Integrated Business Planning
Integrated business planning (IBP) is a business management process that aims to align strategic, operational, and financial planning into a single, integrated process. Objective Integrated business planning (IBP) is used by organizations to integrate various functions and align strategic, operational, and financial planning. Key aspects often included in IBP frameworks are: 1. Functional Integration: IBP aims to integrate departments within an organization and align them functionally. It seeks to create a unified planning process that connects functions such as research and development (R&D), manufacturing, supply chain management, marketing, and sales, incorporating inputs from each to form a common business plan. 2. Harmonization of Planning Cycles:: IBP involves synchronizing planning activities across multiple timelines, aligning monthly, quarterly, and annual planning cycles. It uses a framework designed to address discrepancies arising from separate starting points and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In-network Management
With current network management technologies, management functions typically reside outside the network in management stations and servers, which interact with network elements and devices via network protocols for management, in order to execute management tasks, including fault, configuration, accounting, performance, and security management, or, short ( FCAPS). Most of these tasks are performed on a per-device basis. During network operation, for instance, a management station periodically polls individual devices in its domain for the values of local variables, such as devices counters or performance parameters. These variables are then processed on the management station to compute an estimate of a network-wide state, which is analyzed and acted upon by management applications. This paradigm of interaction between the management system and managed system underlies traditional management frameworks and protocols, including SNMP, TMN and OSI-SM. In the view of Future Internet act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FCAPS
FCAPS is the ISO Telecommunications Management Network model and framework for network management. ''FCAPS'' is an acronym for fault, configuration, accounting, performance, security, the management categories into which the ISO model defines network management tasks. In non-billing organizations ''accounting'' is sometimes replaced with ''administration''. Background The ISO, under the direction of the OSI group, has created a network management model as the primary means for understanding the major functions of network management systems. The model in question is interchangeably called either the ''OSI network management model'' or ''ISO network management model'' so the full name could be the ''OSI/ISO network management model''. The comprehensive management of an organization's information technology (IT) infrastructure is a fundamental requirement. Employees and customers rely on IT services where availability and performance are mandated, and problems can be quickly id ...

Capacity Management
Capacity management's goal is to ensure that information technology resources are sufficient to meet upcoming business requirements cost-effectively. One common interpretation of capacity management is described in the ITIL framework. ITIL version 3 views capacity management as comprising three sub-processes: business capacity management, service capacity management, and component capacity management. As the usage of IT services change and functionality evolves, the amount of central processing units (CPUs), memory and storage to a physical or virtual server etc. also changes. If there are spikes in, for example, processing power at a particular time of the day, it proposes analyzing what is happening at that time and making changes to maximize the existing IT infrastructure; for example, tuning the application, or moving a batch cycle to a quieter period. This capacity planning identifies any potential capacity related issues likely to arise, and justifies any necessary inves ...

Business Service Management
Data center management is the collection of tasks performed by those responsible for managing ongoing operation of a data center. This includes ''Business service management'' and planning for the future. Historically, "data center management" was seen as something performed by employees, with the help of tools collectively called data center-infrastructure management (DCIM) tools. Both for in-house operation and outsourcing, service-level agreements must be managed to ensure data-availability. Competition Data center management is a growing major topic for a growing list of large companies who both compete and cooperate, including: Dell, Google, HP, IBM, Intel and Yahoo. Hardware/software vendors who are willing to live with coopetition are working on projects such as "The Distributed Management Task Force" (DMTF) with a goal of learning to "more effectively manage mixed Linux, Windows and cloud environments." With the ''DMTF'' a decade old, the list of companies is growi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Service Management
Application service management (ASM) is an emerging discipline within systems management that focuses on monitoring and managing the performance and quality of service of business transactions. ASM can be defined as a well-defined process and use of related tools to detect, diagnose, remedy, and report the service quality of complex business transactions to ensure that they meet or exceed end-users Performance measurements relate to how fast transactions are completed or information is delivered to the end-user by the aggregate of applications, operating systems, hypervisors (if applicable), hardware platforms, and network interconnects. The critical components of ASM include application discovery & mapping, application "health" measurement & management, transaction-level visibility, and incident-related triage. Thus, the ASM tools and processes are commonly used by such roles as Sysop, DevOps, and AIOps. ASM is related to application performance management (APM) but serves as a ...
