What is clock synchronization algorithm?
Clock synchronization is a method of synchronizing clock values of any two nodes in a distributed system with the use of external reference clock or internal clock value of the node. During the synchronization, many factors affect on a network.
What are the types of clock synchronization?
There are 2 types of clock synchronization algorithms: Centralized and Distributed.
- Centralized is the one in which a time server is used as a reference.
- Distributed is the one in which there is no centralized time server present.
Is a physical clock synchronization algorithm?
Physical clock synchronization algorithms can be classified as centralized and distributed. These have one node with a real-time receiver and are called time server node. The clock time of this node is regarded as correct and used as reference time. In this method each node periodically sends a message to the server.
Why is computer clock synchronization necessary describe the design requirements for a system to synchronize the clocks in a distributed system?
Describe the design requirements for a system to synchronize the clocks in a distributed system. Major design requirements: i) there should be a limit on deviation between clocks or between any clock and UTC; ii) clocks should only ever advance; iii) only authorized principals may reset clocks (i.e. on Kerberos 7.6.
Can you synchronize two clocks?
Suppose we want to synchronize two clocks that are some distance apart. If, then, we place a flashbulb at the midpoint of the line joining the two clocks, and flash it, the light flash will take the same time to reach the two clocks, so they will start at the same time, and therefore be synchronized.
Why do two clocks synchronize?
The researchers calculated that, as pendulums move back and forth, sound pulses could travel through the wall from clock to clock. These pulses can interfere with the swings of the pendulums, eventually causing them to synchronize.
Which algorithm is a physical clock synchronization algorithm?
Cristian’s algorithm
Cristian’s algorithm (introduced by Flaviu Cristian in 1989) is a method for clock synchronization which can be used in many fields of distributive computer science but is primarily used in low-latency intranets.
Why is clock synchronization necessary?
The Importance of Time Synchronization for Your Network In modern computer networks, time synchronization is critical because every aspect of managing, securing, planning, and debugging a network involves determining when events happen. Time also provides the only frame of reference between all devices on the network.
