Abstract

Network conditions are dynamically measured to extract quality of service condition information that is then translated based on a set of predetermined rules to generate a profile. The profile is configured as structured data about the dynamic state of the network. The profile can be propagated across the network to one or more different locations and to one or more different servers or end users, allowing those systems to adapt to network conditions in real-time.

Claims

1. A system for network condition assessment, comprising:

a network measurement system that monitors a network and develops real-time information about at least one quality of service condition of said network;

a translation module that processes said real-time information based on a set of predetermined rules to generate a profile comprising structured data about the dynamic state of said network.

2. The system of claim 1 wherein said structured data is configured according to a predefined schema.

3. The system of claim 1 wherein said structured data is expressed using a predefined XML vocabulary.

4. The system of claim 1 wherein said structured data is expressed using a predefined first vocabulary that is integrated with a predefined second vocabulary used to describe network device capabilities and preferences.

5. The system of claim 4 wherein said second vocabulary is the CC/PP vocabulary.

6. The system of claim 1 wherein said translation module employs a set of heuristic rules.

7. The system of claim 1 wherein said translation module employs a set of network evaluation rules.

8. The system of claim 1 wherein said profile is configured for storage across a distributed network environment.

9. The system of claim 1 further comprising an information processor coupled to said network;

said processor being configured to parse said profile and to alter its information processing behavior based on the dynamic state of said network as communicated by said profile.

10. A profile generation framework embodied in a networked computer system, comprising:

a network evaluation component configured to monitor network conditions and generate attribute values indicative of at least one quality of service condition of said network;

a profile construction component configured to construct at least one profile based on said attribute values; and

a profile distribution component configured to propagate said profile over said network.

11. The framework of claim 10 wherein said profile construction component employs a set of attribute assigning rules in constructing said at least one profile.

12. The framework of claim 11 wherein said attribute assigning rules are heuristic rules.

13. The framework of claim 10 wherein said profile construction component constructs said profile as structured data about the dynamic state of said network.

14. The framework of claim 13 wherein said structured data is expressed using a predetermined XML vocabulary.

15. The framework of claim 13 wherein said structured data is expressed using a predetermined vocabulary that is constrained with a predetermined device capability vocabulary.

16. The framework of claim 15 wherein said device capability vocabulary is a CC/PP vocabulary.

17. The framework of claim 10 wherein said profile construction component constructs said profile as structured data using a predetermined network vocabulary.

18. The framework of claim 10 wherein said network evaluation component employs network evaluation tools selected from the group consisting of RTP, RTCP, NSMP, ICMP, TCP/IP, UDP/IP, routing protocols and combinations thereof.

19. The framework of claim 10 wherein said network evaluation component monitors network link status properties selected from the group consisting of average loss, average delay, average jitter, and combinations thereof.

20. A method of assessing conditions of a network, comprising:

monitoring said network to develop quality of service information about said network;

translating said quality of service information into at least one profile comprising structured data about the dynamic state of said network; and

propagating said profile over said network.

21. The method of claim 20 wherein said structured data is configured according to a predefined schema.

22. The method of claim 20 wherein said structured data is expressed using a predefined XML vocabulary.

23. The method of claim 20 wherein said structured data is expressed using a predefined first vocabulary that is integrated with a predefined second vocabulary used to describe network device capabilities and preferences.

24. The method of claim 23 wherein said second vocabulary is the CC/PP vocabulary.

25. The method of claim 20 wherein said translating step employs a set of heuristic rules.

26. The method of claim 20 wherein said translating step employs a set of network evaluation rules.

27. The method of claim 20 wherein said profile is configured for storage across a distributed network environment.
