Abstract

A method of monitoring the service level provided to clients by a geospatial web service over a network. The method comprises formulating requests (Rq) relating to different geospatial locations and/or regions; sending the requests (Rq) in sequence to said geospatial web service over said network and receiving respective responses; identifying requests that resulted in responses that include geospatial data for the requested geospatial locations and/or regions; formulating further requests (Rq) relating to different geospatial locations and/or regions by evolving at least a proportion of the identified requests; and iteratively repeating steps b) to d) for the further requests. The method further comprising analysing the responses to determine service level information in respect of the geospatial web service.

1. A method of monitoring the service level provided to clients by a geospatial web service over a network, the method comprising:

a) formulating requests (Rq) relating to different geospatial locations and/or regions;

b) sending the requests (Rq) in sequence to said geospatial web service over said network and receiving respective responses;

c) identifying requests that resulted in responses that include geospatial data for the requested geospatial locations and/or regions;

d) formulating further requests (Rq) relating to different geospatial locations and/or regions by evolving at least a proportion of the identified requests;

e) iteratively repeating steps b) to d) for the further requests,

the method further comprising analysing the responses to determine service level information in respect of the geospatial web service.

2. A method according to claim 1, wherein step a) comprises formulating a set of requests (Rq) belonging to a first generation (i), and step d) comprises, at each iteration, formulating a set of requests (Rq) belonging to a new generation (i+1, i+2, . . . ).

3. A method according to claim 2, wherein each generation includes the same number of requests.

4. A method according to claim 2, wherein, at step d), evolution comprises using a genetic algorithm.

5. A method according to claim 4, wherein step d) comprises pairing two or more of the identified requests and, for the or each pair, breeding one or more child requests.

6. A method according to claim 1, wherein, at step d), evolution comprises mutating one or more of the identified requests to generate one or more mutated requests.

7. A method according to claim 1, wherein step d) comprises formulating one or more further requests (Rq) by randomly generating geospatial locations and/or regions.

8. A method according to claim 7, wherein, where no requests are identified in step c), all further requests (Rq) are formulated at step d) by randomly generating geospatial locations and/or regions.

9. A method according to claim 1 and comprising, at step d), discarding one or more of said identified requests when the number of identified requests exceeds some predefined threshold, and evolving only the remaining identified requests.

10. A method according to claim 1, wherein said step of analysing the responses to determine service level information in respect of the geospatial web service comprises identifying error responses and/or response times.

11. A method according to claim 1, wherein step a) comprises formulating said requests (Rq) relating to different geospatial locations and/or regions by randomly generating geospatial locations and/or regions.

12. A method according to claim 1, wherein, if only a single request is identified at step c), a further request is formulated by randomly generating a geospatial location and/or region, and step d) comprises breeding one or more child requests from said single request and the randomly generated request.

13. A method according to claim 1, wherein each said geospatial location and/or region is/are defined by one or more rectangular areas defined by the coordinates of their opposite lower and upper corner positions.

14. A method according to claim 1, wherein step b) comprises sending the requests (Rq) periodically.

15. A method of monitoring the service level provided to clients by a geospatial web service over a network, the method comprising:

a) formulating a first generation of requests (Rq) relating to different geospatial locations and/or regions;

b) sending the requests (Rq) in sequence to said geospatial web service over said network and receiving respective responses;

c) identifying requests that resulted in responses that include geospatial data for the requested geospatial locations and/or regions;

d) if the number of identified requests exceeds a predefined threshold, discarding one or more requests above the threshold;

e) pairing together ones of the identified requests or remaining identified requests and breeding the or each pair to formulate one or more child requests (Rq) relating to different geospatial locations and/or regions;

f) mutating one or more of the identified requests to formulate one or more mutated requests (Rq) relating to different geospatial locations and/or regions;

g) formulating one or more requests (Rq) relating to different geospatial locations and/or regions by randomly generating a geospatial location and/or region;

h) combining the bred, mutated and randomly generated requests to formulate a further generation of requests (Rq) relating to different geospatial locations and/or regions

i) iteratively repeating steps b) to h) for each further generation,

the method further comprising analysing the responses to determine service level information in respect of the geospatial web service.

16. A method according to claim 15 and comprising, in the event that, for a given iteration, no requests are identified at step c), omitting steps d) to f) and applying step g) to generate all requests of the further generation.

17. A method according to claim 15 and comprising, in the event that only a single request is identified at step c), formulating a request (Rq) relating to different geospatial locations and/or regions by randomly generating a geospatial location and/or region, and breeding the identified request and the randomly generated request to formulate one or more child requests.

18. A computer implemented method of monitoring the service level provided to clients by a geospatial web service over a network, the method comprising:
