Abstract

Method of diagnosis of a heterogeneous network degradation, said heterogeneous network connecting a user terminal and a server through a plurality of links each of said links having a given direction, and comprising at least one home network, one access network and one neighboring network, wherein said method comprises using the neighboring network to determine at least one link of the heterogeneous network in which the degradation occurs and the direction of said link.

Claims

1. Method of diagnosis of a heterogeneous network degradation, said heterogeneous network connecting a user terminal and a server through a plurality of links each of said links having a given direction, and comprising at least one home network, one access network and one neighboring network, the connection of the user terminal to the server being possible via each of the home network and the neighboring network, wherein said method comprises a step of determining at least one link of the heterogeneous network in which the degradation occurs and the direction of said link by using the neighboring network.

2. Method of claim 1, wherein the home network is a wired network and the neighboring network is a wireless network.

3. Method of claim 1, wherein the degradation is a latency and the neighboring network is used to determine the latency of each link of the home network and of the access network.

4. Method of claim 3, comprising the steps of;

a) sending a plurality of probe packets along paths of the heterogeneous network, in which at least one path involves at least one link of the neighboring network;

b) measuring delays on these paths; and

c) combining the measured delays to deduce the latency of each link of the home network and the access network.

5. Method of claim 4, wherein the measured delays are round trip delays.

6. Method of claim 1, wherein the degradation is a packet loss and the neighboring network is used to determine the packet loss on at least one link of the home network and the access network.

7. Method of claim 6, comprising:

d) sending a plurality of probe packets along paths of the heterogeneous network, in which at least one path involves at least one link of the neighboring network;

e) measuring loss rates on these paths; and

f) combining the measured loss rates to deduce the loss rate of each link of the home network (4) and the access network.

8. Method of claim 4, wherein the probe packets are sent from the user terminal.

9. Method of claim 4, wherein the probe packets comprise “

ping”

probes.

10. Method of claim 4, wherein the probe packets comprise cyclic probes.

15. A computer-readable program comprising computer-executable instructions to enable a computer to perform the method of claim 1.

11. Device of diagnosis of a heterogeneous network degradation, said heterogeneous network connecting a user terminal and a server through a plurality of links, each of said links having a given direction, and comprising at least one home network, one access network and one neighboring network, the connection of the user terminal to the server being possible via each of the home network and the neighboring network, wherein said device comprises a diagnosis module operable to determine at least one link of the heterogeneous network in which the degradation occurs by using the neighboring network.

12. Device of claim 11, wherein the degradation comprises a latency.

13. Device of claim 11, wherein the degradation comprises a packet loss.

14. Network node comprising the device of diagnosis of claim 11.
