Maryam Ataei Kachooei, Joshua Chung, Amber Cronin, Benjamin Peters@viasat.com, Feng Li, Jae Won Chung and Mark Claypool talk about a new TCP slow start algorithm SEARCH(Slow start Exit At Right CHokepoint). The authors state that with SEARCH they resolved challenges in wireless links with premature exits from slow start. They will share their kernel changes and results on experiments on WiFi, 4G/LTE, and low earth orbit (LEO) and geosynchronous (GEO) satellite links. More info: https://netdevconf.info/0x18/1
John Ousterhout asks a question: Is it OK to Hijack TCP? John notes that TCP already has all kinds of classical goodies built into the HW offload infrastructure, example TSO, HW GRO, checksum, etc and he wants to take advantage of them. He proposes to masquerade HOMA as TCP on the sender and then disambiguating at the receiver. Come give him some feedback More info: https://netdevconf.info/0x18/19
Amery Hung and Xiaochun Lu will discuss Fine-grained tuning of TCP. Amery and Xiaochun observe that increasing link speeds are inducing the growth of number of flows seen on the wire, with a mix of long or short flows. Unfortunately traditional CC algos like CUBIC favor long flows which conflicts with application desires for throughput and latency. The authors discuss the techniques they use to address these challenges. More info: https://netdevconf.info/0x18/25
