CONFIGURATION English meaning

It’s not really code so it’s not immediately put in version control and it’s not first-class data so It isn’t stored in a primary database. Traditional and small scale system administration is usually done with a collection of scripts and ad-hoc processes. Configuration data can be overlooked at times, but it is critical to system operation. One team member may tweak a hardware allocation value so that the software runs more efficiently on their personal laptop. When the software is later deployed to a production environment, this new configuration may have a suboptimal effect or may break. Many engineering requirements or considerations can influence the selection of CIs.

  • RARP was superseded by the Bootstrap Protocol defined in RFC 951 in September 1985.
  • Since its lease has expired, it will accept any IP address offered to it.
  • It could also aid in decisions on upgrading or purchasing a new system in order to execute certain applications.
  • CI/CD can be set up so that approved configuration change requests can immediately be deployed to a running system.
  • Theorem 1Starting at any arbitrary state of the network, if only greedy sources and source bottlenecked or link bottlenecked sources are present the Algorithm A converges to GW fair allocation.

If the switch algorithm uses the CCR value indicated in the RM cell as the source rate the switch cannot estimate the correct value of source rate of the bottleneck source. But if the switch uses measured source rate then it can correctly estimate the bottlenecked source’s rate. Table4shows the results both when the switch uses the CCR field and when it measures the source rate. The correct fairness is achieved when the measured source rates are used.

How to implement configuration management

The idea of configuration management comes from other institutions, such as the military. When I first started learning about configuration management, I found the concept super confusing. How configuration management fits with concepts like DevOps and agile. Bookmark these resources to learn about types of DevOps teams, or for ongoing updates about DevOps at Atlassian.

definition of configuration

Then, solve the same problem of smaller size after deleting bottleneck links. A similar kind of centralized, recursive algorithm is discussed in . Centralized algorithm implies that all information is known at each switch, which is not feasible, hence a distributed algorithm is necessary. At that time it will restart the DHCP process from the beginning by broadcasting a DHCPDISCOVER message. Since its lease has expired, it will accept any IP address offered to it. Once it has a new IP address it will once again be able to use the network.

This configuration tests whether the GW fairness can be achieved in the presence of source bottleneck. When the network reaches steady state the VCShareterm converges toExcessFairshare, achieving generalized fairness criterion. The complexity of the computations done at the switching interval isO. In order for rebinding to work, when the client successfully contacts a backup DHCP server, that server must have accurate information about the client’s binding.

definition of configuration

Despite their common point of departure, their spatial configurations and handling of the substance differed radically and even conflicted. As will be apparent in the following, these three possibilities correspond to distinct configurations. A variety of different configurations are possible for these devices.

Dynamic Host Configuration Protocol

A client can receive DHCP offers from multiple servers, but it will accept only one DHCP offer. Before claiming an IP address, the client will broadcast an ARP request, in order to find definition of configuration if there is another host present in the network with the proposed IP address. If there is no reply, this address does not conflict with that of another host, so it is free to be used.

definition of configuration

Once a configuration management platform is in place, teams have visibility into the work required for configuration tasks. Configuration management work can be identified as dependencies for other work and properly addressed as part of agile sprints. 3) In installing hardware and software, configuration is sometimes the methodical process of defining options that are provided. 1) In computers and computer networks, a configuration often refers to the specific hardware and software details in terms of devices attached, capacity or capability, and exactly what the system is made up of.

Throughout development and support, the allocation of engineering effort and organization are rooted in the selection of CIs. Developing contractors should participate in the selection process and provide recommendations based upon engineering or other technical considerations. Computer software items, because they typically control the functionality of a system, are almost always designated as CIs. The term CI encompasses both hardware and software; when a statement in this handbook applies only to hardware, or only to software, the terms HWCI and CSCI are used. Webopedia is an online information technology and computer science resource for IT professionals, students, and educators. Webopedia focuses on connecting researchers with IT resources that are most helpful for them.

Configuration management solves this challenge by creating a “source of truth” with a central location for configuration. Rather, character configurations change consistently toward an alternative configuration that is predicted to be most probable according to the expected dynamics of a complex adaptive system. Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. When you press the spacebar, a message appears informing you that “Set-up is inspecting your hardware configuration”.

Agro-environmental partnerships incorporate traditional participants in agriculture, but configure them into intentional and dynamic networks to learn how to optimize ecological relationships in farming systems.

Our expert industry analysis and practical solutions help you make better buying decisions and get more from technology. Data storytelling is the process of translating data analyses into understandable terms in order to influence a business decision… Streaming network telemetry is a real-time data collection service in which network devices, such as routers, switches and … Cloud radio access network (C-RAN) is a centralized, cloud computing-based architecture for radio access networks. DHCP is a network management protocol used to dynamically assign an IP address to any … In the case of software, configuration can also refer to the application’s settings.

It is implemented with two UDP port numbers for its operations which are the same as for the bootstrap protocol . The server listens on UDP port number 67, and the client listens on UDP port number 68. DHCP can be implemented on networks ranging in size from residential networks to large campus networks and regional ISP networks. Many routers and residential gateways have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network.

Translations of configuration

The client may also request repeat data for a particular application. For example, browsers use DHCP Inform to obtain web proxy settings via WPAD. The protocol expects the DHCP client to configure its network interface with the negotiated parameters.

CI/CD Tools Universe: The Ultimate List

Small and midsize businesses often practice configuration management to establish and maintain the consistency of a productʻs performance, functionalities, and physical attributes. Configuration management is a subset of IT service management that ensures that the configuration of computer systems, resources, servers, and assets are reliable. This practice is quite important for small businesses, as system issues and failures can result in a delay in business operations and are often quite costly to fix if not well maintained.

The purpose of IaC is to have a written record of which services exist, where they are located, and under what circumstance. Configuration management might choose to leverage aspects of IaC in order to achieve the full understanding of all the technology assets a company owns. Excessive fragmentation, which may actually decrease Government visibility and understanding of system performance. Fragmented description of functionality increases the overall volume of requirements, is more difficult to understand, and complicates the document review, approval, and control process. Information about configurations can be obtained from the operating system.


Agile software, by definition, reflects the desire to make changes to our software faster so that we can respond to market demands. Configuration management helps us to safely manage our changes and keep velocity high. That hopefully paints a clearer picture of the problems that configuration management is trying to solve. A frequent cause of downtime is bad deployments, which can be caused by differences in running production servers to test servers. With our configuration managed properly, our test environments can mimic production, so there’s less chance of a nasty surprise.

Configuration management was traditionally a purely manual task, completed by a systems administrator. The role was a lot of manual work involving carefully documenting the state of the system. These changes came from the popularity of DevOps, increases in cloud computing, and new automation tooling.
