Methods and systems for incremental calculation of latency variation

摘要

Methods and systems for calculating local latency variations in an incremental manner, including the steps of updating a first local latency variation of a first streaming session at a first output port of a first switch; identifying a relationship that the first streaming session is passing through a second output port of a second switch after passing through the first output port; wherein a second streaming session is passing through the second output port; and updating a second local latency variation of the second streaming session at the second output port, based on the relationship. Wherein the updated second local latency variation is calculated based on the updated first local latency variation.

主权项

1. A network configured to calculate local latency variations in an incremental manner, comprising:
first and second switches comprising first and second output ports, respectively; and a latency variation calculator configured to update a first local latency variation of a first streaming session at the first output port; the latency variation calculator is further configured to identify a relationship that: the first streaming session and a second streaming session are passing through the second output port, and the first streaming session is passing through the second output port after passing through the first output port; the latency variation calculator is further configured to update a second local latency variation of the second streaming session at the second output port, based on the relationship; wherein the updated second local latency variation is calculated based on the updated first local latency variation.
