The World of 100G Networking - Christoph Lameter

2015 saw the arrival of multiple 100Gbps networking technologies: Fast 100G Ethernet switches, Mellanox released EDR (100G Infiniband) and Intel came up with OmniPath (also 100G). 2016 is therefore likely going to be a battleground of these competing technologies. Facebook already is supposed to upgrade their infrastructure to 100G in 2015 and its likely that others are going to follow. This talk gives an overview about the competing technologies in terms of technological differences and capabilities and then discusses the challenges of using various kernel interfaces to communicate at these high speeds (POSIX, RDMA, OFI).
Hopefully we can come up with some ideas how to improve the situation.
