Techniques for exchanging resource information in distributed systems are disclosed. To facilitate the information exchange, a subscription procedure is performed between an information aggregation system and an information dispatch system. During the subscription procedure, the information aggregation system provides/receives a guideline of information adaptation to/from the information dispatch system. The guideline ensures efficient information exchange between the systems. During the information aggregation phase, the aggregation system sends out query messages to each of its subscribed information dispatch systems. If the aggregation system receives a guideline from a particular dispatch system, it will adapt its local query into the dispatch system's format before sending out the query to that system and it will also convert the query results into its local format. Otherwise, the information dispatch system is responsible for information format for the query messages and the query results. |
