Question : cause of high latency

what can be the cause of high latency in lease link network? it is about 10 to 14 second !

Answer : cause of high latency

General Reasons for Latency

Slowdowns can be very apparent over multi-user networks.latency issues cause not only slow service but data losses as well.
At the user level, latency issues may come from software malfunctions; at the network level, such slowdowns may be a result of network overextension or bottlenecking, or DoS or DDoS activity.

As Network Latency in cases like undersea or Sattelite networks, is minimum.
Situatuation can greatly vary depending upon the complexity of the network.

t the user level, latency issues may be caused by PC software. networking tools and applications could be reasons. Traffic can also be slowed by tray icons and spyware that take up network time without any input from the user (and most certainly without his or her consent). Unnecessary icons should be disabled, and spyware checks run frequently.

On the network level Traceroute can indentify the routing latency problem.

Another thing is  DoS/DDoS attacks can affect the speed of an entire network and cause major network latency problems.
