As Internet evolves, so must transport protocols and congestion control. Today’s dominant transport protocol, TCP, was designed primarily for wide area, wired network, and for throughput-sensitive traffic. As cloud-based services, mobile internet access, internet-of-things start sourcing or sinking majority of the internet traffic, new transport protocols and new ways of thinking about congestion control are needed. The workshop will bring together leading researchers to ponder many of these issues, including, but not limited to: – As data center networks continue to evolve and use ever-more exotic technologies (e.g. free space optics), do we need changes to transport protocols? – What is the right congestion control protocol for RDMA networks? – Can wide area networks be made lossless? Do we need to? – Do we need better transport protocols for mobile networks? – Today, majority of the Internet traffic is generated by, or sent to a handful of major players (Google, Netflix, Facebook etc.). Is TCP the right solution in this scenario? – Many of today’s applications are delay sensitive (e.g. collaborative office document editing). Do we need new transport protocols for such applications? – Edge computing (also known as fog computing) is being widely deployed, and will likely play a major role in internet-of-things ecosystem. What transport protocol innovation is needed in this space?
