摘要

This research is about data center redundancy that can recover from a complete or partial disaster using route tracking with Border Gateway Protocol (BGP) for business continuity. The use of geographically distributed multiple data centers provides required redundancy but with higher initial and operating costs. A university or research institute in Japan that is connected to SINET or any other institute that is connected to that regions' academic network can have a disaster recovery site at another university with very low operational and capital cost by co-locating at each other's data centers. One intention of this research is to find a method of business continuance of a University during a major disaster such as experienced in March 11th of 2011 in Japan. With this redundancy method each data center can advertise and operate dedicated networks only available to those data centers while redundancy critical networks which are available at both data centers can be advertised to ISPs (Internet Service Providers) by both data centers with predefined conditions. Due to the local preference of global ISPs incoming traffic path can't always be controlled by the data center side by BGP attribute tweaking. One method to overcome this is to advertise the redundant VIP (virtual IP) network by the primary data center where the secondary data center will start advertising this interested network only when the primary network stops advertising it.
