Abstract

The deficiencies of traditional WebGIS model were analyzed. From the points of load-balancing and map status synchronization, we proposed a new distributed model based on server farm. It used user-defined bottom interactive protocol, distributed dynamic balancing scheduling algorithm and map status object pool to solve many problems in the traditional model such as inefficient heterogeneous compatibility, weak parallel processing capability, and the difficulties in map status synchronization. A test-bed was established to verify the performance of the model. A series of test results has proved that the new WebGIS model has strong heterogeneous compatibility, parallel processing capability and faulttolerant features. Through the mechanism of map status synchronization, the new model can realize sustained preservation and synchronization of map operated statuses and meets the demands of users' uninterrupted accesses.
