(English Abstract)
Most of the RDMA applications use either RC QP(Reliable Connected Queue Pair) or UD QP(Unreliable Datagram Queue Pair). RC QP has advantages with regards to usability and disadvantages with respect to scalability; while UD QP is scalable but hard to use. DCT (Dynamically Connected Transport) has been introduced to address the limitations when using one of the existing QPs. However, DCT is only available with hardware support. In this paper, we have designed and implemented a totally software-based DCT prototype to eliminate hardware dependency. Our experimental results show that our prototype adds only negligible overhead while providing the advantages of both RC QP and UD QP. Furthermore, we present and evaluate write and evaluate a DC QP-based application to prove its effectiveness compared to the RC QP-based application.
