![]() For some operators, limited licensed spectrums are insufficient, and using others' unused spectrums becomes necessary. Government agencies lease different spectrums to different mobile operators, resulting in the underutilization of spectrums in some areas. Because both the bandwidth and spectrums are limited, maximizing the utilization of a spectrum is a target for next-generation technologies. N2 - Mobile devices are advancing every day, creating a need for higher bandwidth. T1 - Cognitive radio network technologies and applications While other works on DSRC and Wi-Fi sharing exist, in this chapter, we discuss LTE and Wi-Fi sharing specifically.", Because of this, ensuring that the spectrum is fairly shared among different technologies is quite challenging. After the Federal Communications Commission (FCC) declared the 5 GHz band unlicensed, Wi-Fi, LTE, and other wireless technologies became willing to access the band, leading to a competition for the spectrums. In this chapter, we present the complete architecture of CRN, and we additionally discuss other scenarios including the applications of the CRN. In CRN architecture, each user must determine the status of a spectrum before using it. The unlicensed usage of others' spectrums is possible if the licensed users are not using the spectrum, and this gives rise to the idea of cognitive radio networks (CRNs). While other works on DSRC and Wi-Fi sharing exist, in this chapter, we discuss LTE and Wi-Fi sharing specifically.Ībstract = "Mobile devices are advancing every day, creating a need for higher bandwidth. ![]() Mobile devices are advancing every day, creating a need for higher bandwidth. ![]() ![]() ![]() ZFS is designed with two major goals in mind: to handle large amounts of storage and prevent data corruption. How ZFS is different than other filesystems? Let’s see why ZFS matters and how to take advantage of it on ZFS install of Ubuntu. When the command is entered, the system will ask you for the root password type it and press Enter.You can choose ZFS while installing Ubuntu 19.10 You’ll need the Terminal for installation, so press the key shortcut Ctrl+Alt+T to open it. Now let’s explore how to install ZFS on a Linux operating system, with the example of Ubuntu version 20.04. Having chosen the type of redundancy, the only solution is to destroy it and create a new one, while restoring data from backups or another location. ![]() Also, there are limitations in changing the redundancy type.Įxcept for switching a single disk-based pool to a mirroring pool, you cannot change the redundancy type. You cannot remove devices or vdevs (which stands for virtual devices) from the pool after they have been added. No opportunities to reduce the storage pool. When the current pool eats up 80% of the available storage, you should either expand the pool or migrate it to a storage system with a larger capacity. This is a commonplace problem for many file systems. When its storage capacity is used by 80% or more, the ZFS performance tends to degrade heavily. However, just as any other file system, ZFS does have a few drawbacks. On the other hand, in ZFS the new information is written to a different block.Ĭlones are identical copies of something. In most file systems, data is lost forever when overwritten. After that, the file system tries to repair such an error automatically.Īlso, ZFS is perfectly scalable with the possibility of adding new storage devices, cache management options and so on. If the checksum does not match the read data, ZFS identifies an error. Later, when the data is read, the checksum is verified again. While some data is written, its checksum is calculated and written as well. Another advantage is related to ensuring data integrity. This approach also simplifies monitoring as there are less levels to be considered. All you need to manage volumes, redundancy levels, file systems, compression ratios, and mount points is just a few commands. It combines management of volumes, RAID arrays, and the file system. Talking of ZFS advantages, the following can be distinguished: It has a simplified pattern of administration. ZFS File System on Linux Ubuntu and Its Key Advantages ZFS advantages ZFS is an open-source project licensed under CDDL (Common Development and Distribution License). Unlike many other systems, ZFS is a 128-bit file system offering a virtually unlimited capacity. It is a next generation file system initially designed for NAS solutions with improved security, reliability and performance. It supports huge amounts of data, combines the concepts of a file system, physical disk and volume manager, and offers simple management methods for storage volumes. ZFS or Zettabyte File System is a special file system initially created by Sun Microsystems for the operating system called Solaris.

![]() ![]() The utility continuously processes the user-defined address and displays the results in real-time in the main window. PingPlotter Freeware gives you the possibility to tweak some dedicated parameters before triggering the process, such as the number of times to sample, delay time between samples (in seconds), as well as the number of samples that is included in the graph. The tool lets you insert the address that you want to trace in a dedicated panel, start or stop the tracing process, and view additional information about the recorded values with aid of a built-in graph that displays data in real-time. The clean feature lineup makes it easier for you to discover the program’s functions. The tool’s aim is to continuously gather and record information about any packet loss. PingPlotter Free is a small Windows application whose purpose is to help you trace the route between you and a user-defined address (be it a website, VoIP provider, or online game server). However, you can switch to the standard edition at startup and restart the tool to use it. The clever design lets you quickly accommodate while tab support gives you the possibility to simultaneously monitor multiple URLs or IP addresses.Note: By default, the application runs the professional edition of PingPlotter after installation. On an ending note, PingPlotter Pro is a handy network administration tool with which you can constantly keep an eye on multiple targets and receive alerts whenever unexpected events occur. As such, you can write down a custom name for easy identification, set the number of samples to examine, the method used which can either be for latency and packet loss or MOS, multiple target configurations, as well as the action to trigger when conditions are met. ![]() ![]() The notification system gives you the possibility to set up several parameters to be announced of any changes. Bringing up the context menu enables you to manage a few more settings like obtaining whois info, display summary, show graphs or even configure alerts. Each element you select highlights all of its components for better view. For short-term analysis, the sampling number can be set, with the default value being unlimited, trace intervals can be specified in seconds, as well as the number of samples to include.Īs soon as the process is put in motion, all packets are displayed, with a timeline view updating in real time according to your specifications. On the other hand, there are several settings to configure, depending on the testing scenario. Hitting the “Start” button is all it takes to send a few packets to the selected target. All targets are saved in a list so you can quickly access them later on. Connecting to a target is easily done by manually writing down either the URL or IP address in a dedicated fields. What's more, you can save your workspace configuration to use for multiple tasks and this comes in handy because you can slightly customize the view with more or less tabs and sections.Ĭonfigure connection settings and trace multiple targetsĪ neat advantage is the possibility to simultaneously trace multiple addresses, with detail windows stored in tabs. The application's design is pretty intuitive, with adjustable panels so you can clearly view packets, timelines or project elements so you can quickly access them. Amongst others, you can use PingPlotter Pro to carefully monitor multiple addresses and trigger alerts when unexpected events occur. Keeping a network, server or a website active means constantly monitoring incoming and outgoing packets to make sure connectivity is flawless. Network administrators need to be ready for various events that don't necessarily mean virtual attacks. Monitor and troubleshoot your networks, gather information about remote hosts, track latency, packet loss and others, with this useful tool. ![]() ![]() ![]() ![]() ➤Great for any room, our wall decor piece will brighten up your home for sure.It also makes lovelygift for friends and family. ➤Are bare walls turning your rooms into stuffy studies, dreary dens, and boring bathrooms?
