ViNO: SDN overlay to allow seamless migration across heterogeneous infrastructure
Spandan Bemby, Hongbin Lu, Khashayar Hossein Zadeh, Hadi Bannazadeh, Alberto Leon‐Garcia · 2015
We propose ViNO (Virtual Network Overlay), an orchestration service that can be used to create arbitrary network topologies with OVS (Open vSwitch) switches and VMs. ViNO connects switches and VMs through an overlay network using VXLAN encapsulation. ViNO provisions VMs by making API calls to the underlying platform. Users specify the desired topology using an expressive Domain Specific Language that allows users to easily express commonly used network topologies while hiding the underlying complexity. An important use case for ViNO is enabling the seamless migration of Linux services across VMs in different regions with very little downtime.
