Abstract
A method and apparatus for improving the performance of Building Environmental Control networks by efficiently storing network routing information and by checking that the data exchanged between two computer applications operating on the network is consistent. The present invention efficiently stores network routing information by having the Building Environmental control network routers only store routing information when that router acts as a bridge for communicating that message further downstream. The present invention also checks that the exchange of data between two building environmental control applications is done by forming a special identifier from the existing data and using that identifier to validate data exchanges. The special identifier is formed by segmenting one field found within the data and having a portion of that segmented field be indicative of the identifying name of the data.
