In the modern data center, traditional technologies are limiting the speed, flexibility, scalability, and manageability of application deployments. There is emerging interest in the industry in overlay technologies, which may address some of these challenges. In the IETF, the NVO3 Working Group [NVO3] has been chartered to develop a set of protocols enabling network virtualisation within a data center (DC) environment, assuming an IP-based underlay.

Currently several encapsulation protocols are under discussion in NVO3, namely: GENEVE, VXLAN-GPE, GUE. While similar, these protocols have their own peculiarities. The purpose of the project is explore the differences and the similarities of the different proposals, as well as evaluating their performance either analytically or via simulation/emulation.
