Free and open-source software portal; Unison is a file synchronization tool for Windows and various Unix-like systems (including macOS and Linux). [3] It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
Spacewalk Server: Server represents managing System It is possible to set up primary and worker servers, and even a tree setup is possible [6] There are options for geographically remote proxy servers [7] Spacewalk Client: A system managed by a Spacewalk server Compatible Client OS's are drawn from: Red Hat Enterprise Linux (RHEL) CentOS; Fedora
Cristian's algorithm works between a process P, and a time server S connected to a time reference source. Put simply: P requests the time from S at time t 0. After receiving the request from P, S prepares a response and appends the time T from its own clock. P receives the response at time t 1 then sets its time to be T + RTT/2, where RTT=t 1-t 0.
More complete synchronization systems, although lacking NTP's data analysis and clock disciplining algorithms, include the Unix daemon timed, which uses an election algorithm to appoint a server for all the clients; [19] and the Digital Time Synchronization Service (DTSS), which uses a hierarchy of servers similar to the NTP stratum model.
In a system with a central server, the synchronization solution is trivial; the server will dictate the system time. Cristian's algorithm and the Berkeley algorithm are potential solutions to the clock synchronization problem in this environment. In distributed computing, the problem takes on more complexity because a global time is not easily ...
Synchronization is as important as power at the cell site. [3] The quote above suggests that one can think of holdover in synchronization applications as analogous to running on backup power. Modern wireless communication systems require at least knowledge of frequency and often knowledge of phase as well in order to work correctly.
zsync is an rsync-like tool optimized for many downloads per file version. zsync is used by Linux distributions such as Ubuntu [38] for distributing fast changing beta ISO image files. zsync uses the HTTP protocol and .zsync files with pre-calculated rolling hash to minimize server load yet permit diff transfer for network optimization. [39]
The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems. [ 1 ]
