BGP design for the separation of the local big data traffic in data center

Abstract

As the service for big data increases, the number of analysis servers for big data grows rapidly. For example, the scale of analysis servers for the big data from Large Hadron Collier in Swiss CERN is generally beyond tens of thousands of servers. Therefore, tasks for the selection of the appropriate local routing protocol and the efficient configuration of the routing protocol for those servers are getting more important portion in the local network administration in big data center. In this paper, we introduce BGP as a routing protocol for the local network of big data center even though it is developed for WAN. The concept we introduced in this paper for the separation of big data traffic in local data center network is created based on the concept of the partition of the conference room in convention center. The main conference room can be partitioned by multiple small meeting rooms according to users' requests. Each small room can be protected from the noise of the neighbor meeting rooms by partition walls. In the same way, the huge number of servers can be grouped into various server farms and then each of server farms can be identified Autonomous System number that is used for the BGP routing domain for network administrator. Using the techniques of AS numbering we can control the big data traffic more efficiently than ever in data center. We introduced new application method of AS number for a service to recognize certain traffic. Therefore, we can separate and control big data traffic more in detail. We tried to prove that BGP is superior to IGP and overlay networking with respect to the routing control in big data center.
