CoRD: Converged RDMA Dataplane for High-Performance Clouds
High-performance networking is often characterized by kernel bypass which is
considered mandatory in high-performance parallel and distributed applications.
But kernel bypass comes at a price because it breaks the traditional OS
architecture, requiring applications to use special APIs and limiting the OS
control over existing network connections. We make the case, that kernel bypass
is not mandatory. Rather, high-performance networking relies on multiple
performance-improving techniques, with kernel bypass being the least effective.
CoRD removes kernel bypass from RDMA networks, enabling efficient OS-level
control over RDMA dataplane.Comment: 11 page
The state of peer-to-peer network simulators
Networking research often relies on simulation in order to test and evaluate new ideas. An important requirement of this process is that results must be reproducible so that other researchers can replicate, validate and extend existing work. We look at the landscape of simulators for research in peer-to-peer (P2P) networks by conducting a survey of a combined total of over 280 papers from before and after 2007 (the year of the last survey in this area), and comment on the large quantity of research using bespoke, closed-source simulators. We propose a set of criteria that P2P simulators should meet, and poll the P2P research community for their agreement. We aim to drive the community towards performing their experiments on simulators that allow for others to validate their results
