Patent attributes
Techniques are disclosed for virtualized server kernel and virtual networks consolidation. The network consolidation allows a data center to migrate from an infrastructure that uses multiple dedicated gigabit Ethernet Network Adapters to manage system virtualization and migration to an infrastructure using consolidated, redundant, 10 gigabit Ethernet adapters. Different priority classes may be defined for different classes of network traffic such as hypervisor management traffic, inter-host virtual machine migration traffic, virtual machine production traffic, virtualized switching control plane traffic, etc. Further, an enhanced transmission standard may be used to specify a minimum bandwidth guarantee for certain traffic classes. Thus, the hypervisor management and inter-host virtual machine migration traffic may be transmitted, even the presence of congestion.
