Virtual Network Switch Architecture for Scalable Overlay Networks

The patent introduces a virtual network switch as an intermediary layer between the virtualization layer and the physical network components. This virtual switch enables users to control and customize network features without directly accessing physical hardware, thereby maintaining security while improving user control and flexibility.

The patent creates a universal virtual network switch architecture that can operate across different physical network infrastructures. The virtual switch implements a standardized interface that works with various underlying hardware combinations, enabling applications to be portable across different cloud networks while maintaining optimized performance through provider-specific features when needed.

The patent segments the network virtualization architecture into distinct layers: a simplified user-facing virtualization layer and a virtual network switch layer that provides detailed visibility. This segmentation allows the upper layer to remain simple while the virtual switch layer maintains comprehensive visibility and control over data paths, packet routing, and network activities.

The patent implements a dynamic virtual network switch architecture that can adapt its functionality based on requirements. The system maintains core reliability functions while dynamically enabling additional features such as custom routing policies, quality of service controls, and network segmentation when needed, thereby providing both reliability and versatility.
