Where does clock synchronization is done?
The most used clock synchronization solution on the Internet is the Network Time Protocol (NTP) which is a layered client-server architecture based on User Datagram Protocol (UDP) message passing. Lamport timestamps and vector clocks are concepts of the logical clock in distributed computing.
What is difference between SNTP and NTP?
NTP (Network Time Protocol) and SNTP (Simple Network Time Protocol) are similar TCP/IP protocols in that they use the same time packet from a Time Server message to compute accurate time. The difference between NTP and SNTP is in the error checking and the algorithm for the actual correction to the time itself.
What is clock synchronization and why it is needed?
Clock synchronization is necessary for the ordering of events and to preserve the state of resources. As per algorithms, we can say that for clock synchronization there is need to consider propagation time of messages among each node in both types of algorithms centralized and distributed.
Why is NFS not synchronized between client and server?
NFS does not synchronize time between client and server, and offers no mechanism for the client to determine what time the server thinks it is. What this means is that a client can update a file, and have the timestamp on the file be either some time long in the past, or even in the future, from its point of view.
What do you need to know about synchronized clocks?
Synchronized Clock Systems Explained. What is a Synchronized Clock System? A synchronized clock system provides the exact same time to all clocks in the system. The synchronized clock system typically consists of a “master clock” and multiple “secondary clocks” also known as “slave clocks”.
Why is it important to use the NFS protocol?
As protocols go, NFS has been widely accepted. Every network operating system has had NFS ported to it in one form or another, and it is used in almost every Unix environment worldwide. It provides a convenient mechanism for sharing data across platforms, and is a relatively robust, nearly ubiquitous solution to centralized data storage problems.
