Abstract

Disclosed herein is a method, a computer program product, and a carrier for indicating one-way latency in a data network (N) between a first node (A) and a second node (B), wherein the data network (N) lacks continuous clock synchronization, comprising: a pre-synchronisation step, a measuring step, a post-synchronisation step, an interpolation step, and generating a latency profile. The present invention also relates to a computer program product incorporating the method, a carrier comprising the computer program product, and a method for indicating server functionality based on the first aspect.

First claim

The invention claimed is:

1. A method for determining one-way latency between a first computer node (A) having a first clock and a second computer node (B) having a second clock, comprising:
pre-synchronizing said first clock of said first computer node (A) with said second clock of said second computer node (B),
said pre-synchronizing further comprising obtaining a first clock difference value and a first absolute clock value;
measuring a sending time and a receiving time ass…
