What does GVT mean in UNCLASSIFIED

GVT stands for Global Virtual Time, which defines an absolute time reference that is not affected by latency or geographical location. It ensures synchronization of real-time activities conducted on a distributed network.

GVT is calculated from the maximum virtual time amongst all nodes in the distributed system. This allows each node to calculate its local virtual time with respect to the global maxima, using the clock skew and latency parameters.

By using GVT, it's possible to easily synchronize activities between two or more nodes on a distributed network regardless of their geographical location or latency present in the system.

The components of Global Virtual Time are Global Clock Skew, Global Max Delay and Clock Drift rate. These three parameters work together to ensure successful synchronization between different nodes on a distributed network.

Using Global Virtual Time helps ensure that messages sent over a distributed system arrive at their intended destination within an acceptable time limit, thus making it easier for applications running in such systems to run efficiently and effectively.

Local Virtual Time (LVT) is a relative measure of time derived from the GVT. It allows each node running on a distributed system to calculate their respective time values by taking into consideration factors such as clock skew and latency present in the system.

Accurate utilization of Global Virtual Time ensures that messages sent over a distributed system arrive at their correct destination within an acceptable amount of time thus enabling applications running over the distributed system to run optimally without any undue delays or glitches.

The use of GVT allows multiple nodes on a computer network to keep their respective clocks synchronized with one another regardless of latency or geographical location ensuring that messages are delivered correctly and within an acceptable amount of time.

By utilizing Global Virtual Time, communication efficiency can be improved as accurate timestamps can be attached to messages sent across multiple computers reducing errors due to discrepancies in timestamps among different nodes thus allowing applications running over these networks perform significantly better.
