Tom Herbert, Fred Templin and Rachel Dudukovich discuss interplanetary and space communications in this moonshot talk. Ping to Mars, anyone? ;-> Traditional transport protocols including TCP don't fare well in the presence of long delays, so alternative protocols are needed. The authors discuss architectural challenges in dealing with these sorts of networks aptly named as Delay-tolerant networks, or DTN.

Cong Wang and A K M Fazla Mehrab discuss Transparent Shared Memory Communications using eBPF in this moonshot talk. The authors note two challenges with co-resident VMs when resources are shared. First, due to high overheads of switches and events in host/guest domain and VMM. Second, very costly the communication overhead between co-resident VMs. To address this challenge the authors are proposing using BPF arena as a foundation alongside socket maps and sockops infrastructure to solve this problem.

Parav Pandit, Yishai Hadas, Avihai Horon, Feng Liu and Satananda Burla describe their journey to advancing device migration for virtio PCI hardware devices. Live migration of VMs with pass-through virtual functions is essential for hypervisor infrastructure. In this talk the authors detail the evolution of the various design aspects of the spec, implementation challenges, their solutions, comparisons against vendor-specific approaches and IDPF. They finally share the lessons learnt in the journet and share present performance benchmarks.
