Clock-sampling mutual network synchronization[ edit ] Clock-sampling mutual network synchronization CS-MNS is suitable for distributed and mobile applications. It has been shown to be scalable over mesh networks that include indirectly-linked non-adjacent nodes, and is compatible with IEEE It can be accurate to the order of few microseconds, but requires direct physical wireless connectivity with negligible link delay less than 1 microsecond on links between adjacent nodes, limiting the distance between neighboring nodes to a few hundred meters.
A time client will maintain its clock by making a procedure call to the time server. Variations of this algorithm make more precise time calculations by factoring in network radio propagation time. Work on these standards started in October , and the original standards were accepted in Well tested over the years, it is generally regarded as the state of the art in distributed time synchronization protocols for unreliable networks.
It can reduce synchronization offsets to times of the order of a few milliseconds over the public Internet, and to sub-millisecond levels over local area networks. A simplified version of the NTP protocol, SNTP , can also be used as a pure single-shot stateless master-slave synchronization protocol, but lacks the sophisticated features of NTP, and thus has much lower performance and reliability levels.
Since the earlier phases are not specific to the operating system, the BIOS-based boot process for x86 and x architectures is considered to start when the master boot record MBR code is executed in real mode and the first-stage boot loader is loaded. Thus no boot loader is necessary. Below is a summary of some popular boot loaders: LILO does not understand or parse filesystem layout.
The configuration file, which includes data such as boot partition and kernel pathname for each, as well as customized options if needed, is then written together with bootloader code into MBR bootsector. When this bootsector is read and given control by BIOS, LILO loads the menu code and draws it then uses stored values together with user input to calculate and load the Linux kernel or chain-load any other boot-loader.
GRUB 1 includes logic to read common file systems at run-time in order to access its configuration file. It also contains a command-line interface , which makes it easier to fix or modify GRUB if it is misconfigured or corrupt. The first-stage loader stage1 is loaded and executed either by the BIOS from the Master boot record MBR or by another boot loader from the partition boot sector.
Its job is to discover and access various file systems that the configuration can be read from later. The optional, intermediate stage loader stage1.
The second-stage loader stage2 is loaded last and displays the GRUB startup menu that allows the user to choose an operating system or examine and edit startup parameters. After a menu entry is chosen and optional parameters are given, GRUB loads the kernel into memory and passes control to it. GRUB 2 is also capable of chain-loading of another boot loader.
It is often used for boot or rescue floppy discs, live USBs , and other lightweight boot systems. Loadlin is a boot loader that can replace a running DOS or Windows 9x kernel with the Linux kernel at run time. This can be useful in the case of hardware that needs to be switched on via software and for which such configuration programs are proprietary and only available for DOS. This booting method is less necessary nowadays, as Linux has drivers for a multitude of hardware devices, but it has seen some use in mobile devices.
This is loaded in two stages — in the first stage, the kernel as a compressed image file is loaded into memory and decompressed, and a few fundamental functions such as basic memory management are set up.
Control is then switched one final time to the main kernel start process.Throughout the book we will use the term computer network to mean a. Tanenbaum has an S.
Previous editions. Tanenbaum: Computer Networks, 3rd. Kernel loading stage[ edit ] The kernel is typically loaded as an image file, compressed into either zImage or bzImage formats with zlib.
