Recently many advanced communication applications which need wide bandwidth appear by the advancing the development of Internet environment. And the demand for real-time video transmission for conference system is increased. Currently end users of these application focus on only network bandwidth. Stable real-time transmission needs such Internet environment that has enough wide bandwidth and is controlled by stable routing information. If routing control is not so stable, bandwidth, delay and jitter of communication are not stable and communication would be sometimes disconnected. Then statistics information of routing can be useful to know the network is stable or not. We focus on inter domain routing information such as routing information of BGP between some AS and the other AS. We use BGPView to collect such routing information. But the routing information is usually large amount of data size. We make method for process large data and make database system named ABEL based on that information. Because of that method this database system respond quickly. It's useful for network administrators who want to know the stability of Internet and some application which need knowledge about stable network.
