Abstract

A system and method of automatically controlling in-bound traffic from a first communications peer to a second communications peer based on an input from a historical path quality assessment and prediction system is disclosed. The second communications peer receives an input from the historical path quality assessment and prediction system, selects a path through a relay based on the received input, requests allocation of the relay, and sends an address of the selected relay to the first communications peer. The system and method works in concert with an Interactive Connectivity Establishment (ICE) mechanism, or takes advantage of the features of the Interactive Connectivity Establishment (ICE) mechanism.

Claims

1. A method of automatically controlling traffic between communications peers, the method comprising:

performing path quality assessments for a first portion of a path between a first communications peer and a second communications peer at a first historical path quality assessment and prediction system;

performing path quality assessments for a second portion of the path between the first communications peer and the second communications peer at a second historical path quality assessment and prediction system;

concatenating the path quality assessments for the first and second portions of the path between the first communications peer and the second communications peer at the second communications peer or the second historical path quality assessment and prediction system, wherein the path quality assessments include one or more quality metrics that are indicated in an Interactive Connectivity Establishment (ICE) mechanism; and

making a path selection decision at the second communications peer or the second historical path quality assessment and prediction system based on the concatenated path quality assessments.

2. The method according to claim 1, further comprising:

selecting an Interactive Connectivity Establishment (ICE) candidate pair based on the path selection decision.

3. The method according to claim 1, wherein the second portion of the path exists between the second communications peer and a relay, and

wherein the first portion of the path exists between the first communications peer and the relay.

4. The method according to claim 1, wherein the indication in the Interactive Connectivity Establishment (ICE) mechanism is in an ICE candidate priority field.

5. The method according to claim 1, further comprising:

sending, by the second communications peer to the first communications peer, one of an update or a re-invite including a transport address associated with the path selection decision.

6. The method according to claim 1, wherein the path between the first communications peer and the second communications peer includes only the first and second portions and at least one relay.

7. A system for automatically controlling traffic between communications peers, the system comprising:

a first communications peer;

a first historical path quality assessment and prediction system that performs path quality assessments for a first portion of one or more paths;

a second communications peer; and

a second historical path quality assessment and prediction system that performs path quality assessments for a second portion of the one or more paths,

wherein the second communications peer or second historical path quality assessment and prediction system concatenates the path quality assessments for the first and second portions of the one or more paths,

wherein the path quality assessments include one or more quality metrics that are indicated in an Interactive Connectivity Establishment (ICE) mechanism, and

wherein the second communications peer or second historical path quality assessment and prediction system makes a path selection decision based on the concatenated path quality assessments.

8. The system according to claim 7, wherein the second historical path quality assessment and prediction system performs the path quality assessments for a portion of the path between the second communications peer and a relay, and

wherein the first historical path quality assessment and prediction system performs the path quality assessments for a portion of the path between the first communications peer and the relay.

9. The system according to claim 7, wherein the second communications peer or second historical path quality assessment and prediction system selects an Interactive Connectivity Establishment (ICE) candidate pair based on the path selection decision.

10. The system according to claim 7, wherein the indication in the Interactive Connectivity Establishment (ICE) mechanism is in an ICE candidate priority field.

11. The system according to claim 7, wherein the second communications peer sends to the first communications peer one of an update or a re-invite including a transport address associated with the path selection decision.

12. The system according to claim 7, wherein the path between the first communications peer and the second communications peer includes only the first and second portions and at least one relay.
