Automatic capture of the network delay components
View Patent ↗In a method for monitoring the residence time across nodes of a communication network including a transparent clock-based synchronization architecture, the method includes configuring and generating a tunable and traceable packet dedicated to delay measurements. The method further includes measuring the packet resident time across a network node by a transparent clock, storing, at the level of the network node, the measured residence time, and retrieving the stored residence time by a Network protocol.
1. A method for monitoring a residence time across a plurality of nodes of a communication network including a transparent clock based synchronization architecture according to Precision Time Protocol release 2 (PTPV2), said method comprising:
configuring and generating a modified PTPV2 packet, the modified PTPV2 packet being used for at least measuring the residence time but is not used for a synchronization purpose;
measuring the residence time of the modified PTPV2 packet across a at least one node of the plurality of nodes, by a transparent clock;
storing the measured residence time; and
retrieving the stored residence time using a network protocol.
2. The method of claim 1 , further comprising:
parameterizing the modified PTPV2 packet.
3. The method of claim 2 , wherein the parameterizing parameterizes the modified PTPV2 packet with respect to at least a parameter of a delay-sensitive application packet.
4. The method of claim 3 , wherein the parameter is a quality of service (QoS).
5. The method of claim 3 , wherein the parameter is a packet length.
6. The method of claim 1 , wherein the modified PTPV2 packet is a modified PTPV2 delay request packet.
7. The method of claim 1 , wherein the storing stores the measured residence time in a centralized storage.
8. The method of claim 1 , further comprising:
analyzing the measured residence time.
9. The method of claim 1 , further comprising:
multicast sending of the modified PTPV2 packet.
10. A network node supported by a transparent clock, the network node comprising:
a memory including computer readable instructions stored therein; and
a processor configured to execute the computer readable instructions to,
configure and generate a modified Precision Time Protocol release 2 (PTPV2) packet, the modified PTPV2 packet being used for at least measuring a residence time but is not used for a synchronization purpose;
measure the residence time of the modified PTPV2 packet across said network node, using the transparent clock;
store the measured residence time; and
retrieve the stored residence time using a network protocol.
11. The method of claim 10 , wherein the transparent clock includes an IEEE 1588 version 2 Peer-to-Peer Transparent Clock.
12. The method of claim 10 , wherein the transparent clock includes an IEEE 1588 Version 2 end-to-end Transparent Clock.
13. A non-transitory computer readable medium comprising computer-readable instructions which when executed by a processor, cause the processor to,
configure and generate a modified Precision Time Protocol release 2 (PTPV2) packet, the modified PTPV2 packet being used for at least measuring a residence time but is not used for a synchronization purpose;
measure the residence time of the modified PTPV2 packet across at least one node of a plurality of nodes of a communication network, by a transparent clock;
store the measured residence time; and
retrieve the stored residence time using a network protocol.
