Abstract
Official abstract text for this publication.
In general, the present invention relates to a virtual platform in which one or more distributed virtual switches can be created for use in virtual networking. According to some aspects, the distributed virtual switch according to the invention provides the ability for virtual and physical machines to more readily, securely, and efficiently communicate with each other even if they are not located on the same physical host and/or in the same subnet or VLAN. According other aspects, the distributed virtual switches of the invention can support integration with traditional IP networks and support sophisticated IP technologies including NAT functionality, stateful firewalling, and notifying the IP network of workload migration. According to further aspects, the virtual platform of the invention creates one or more distributed virtual switches which may be allocated to a tenant, application, or other entity requiring isolation and/or independent configuration state. According to still further aspects, the virtual platform of the invention manages and/or uses VLAN or tunnels (e.g, GRE) to create a distributed virtual switch for a network while working with existing switches and routers in the network. The present invention finds utility in both enterprise networks, datacenters and other facilities.
First claim
Opening claim text (preview).
What is claimed is: 1. For a network hypervisor, a method of managing a network comprising physical forwarding elements, the method comprising: identifying a set of virtual machines communicatively coupled to a set of physical forwarding elements, at least one of the physical forwarding elements in the set of physical forwarding elements also coupled to a virtual machine that is not in the set of virtual machines; generating a set of flow entries for the set of physical forwardi…
