DB2 Universal Database Enterprise-Extended Edition (DB2 UDB EEE) is a parallel relational database management system using a shared-nothing architecture. DB2 UDB EEE uses multiple nodes connected by an inter-connect and partitions data across these nodes. The communication protocol used between nodes of DB2 UDB EEE has historically been Transmission Control Protocol (TCP) / Innternet Protocol (IP) but has now been extended to include the Virtual Interface (VI) Architecture. This paper discusses a new protocol termed Virtual Interface Protocol (VIP), built on top of the primitives provided by the VI Architecture. DB2 UDB EEE with VIP on a fast interconnect has shown significant improvement in reducing the elapsed itme of queries when compared with TCP/IP over fast ethernet. This paper discusses the implementation and performance results on a Transaction Processing council's Decision (TPC-D) support database.
