Methods and Apparatus for Providing Adaptive Private Network Centralized Management System Timestamp Correlation Processes

摘要

System and techniques are described which provide a method for time correlated monitoring of nodes in a network. A statistics request message is sent from a centralized control point to a node in a network having a plurality of nodes, wherein the statistics request message contains a centralized control point time stamp tn of when the message was sent. The statistics request message is received at the node which records a node timestamp ta when the message was received in the node. Node statistics are converted to system time at the centralized control point according to a first delta between tn and ta to generate adjusted node statistics. A second delta is determined at the centralized control point which is applied to the adjusted node statistics to provide consistent system time information for feedback or presentation through a network attached user interface.

1. A method for time correlated monitoring of nodes in a network, the method comprising:
sending a statistics request message from a centralized control point to a node in a network having a plurality of nodes, wherein the statistics request message contains a centralized control point time stamp tn of when the message was sent; receiving the statistics request message at the node which records a node timestamp ta when the message was received in the node; returning the requested node statistics to the centralized control point; converting the received node statistics to time at the centralized control point according to a first delta between tn and ta; and determining a second delta which is applied to the received node statistics to provide consistent system time information for feedback through a network attached user interface.
