Costs of persisting data over networks have been dominated by slow access latency to disks or SSDs, and access methods to them, causing end-to-end latency on the order of hundreds or thousands of microseconds. As a result, networking whose RTTs over TCP and HTTP take tens of microseconds, was a relatively lightweight component of the end-to-end system. However, emerging non-volatile main memory (NVMM) will change this phenomenon, because durably writing data become two-three orders of magnitude faster because of physical speed and new access methods. This bottlenecks the network stack, necessitating re-designing it.
We propose PASTE, a new networking API to build networked storage systems on top of it. It achieves high performance by run-to-completion and DMA performed to named packet buffers on NVMM, while preserving protection, efficiency and ability to leverage a rich set of network protocols provided by the socket API today. We benchmark PASTE using Write-Ahead Logging and B+tree, as well as porting it to key value stores and software switch, and show PASTE significantly outperforms well-tuned Linux and the state-of-the art network stack. The work is to appear in NSDI'18 (http://web.sfc.wide.ad.jp/~micchie/papers/paste-nsdi18.pdf).
