Virtual Network Device for Cloud VM Scalability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard network devices in cloud computing environments struggle to manage communications between a large number of virtual machines (VMs), despite supporting thousands of VLANs and MAC addresses, limiting scalability.
Innovation Solution
Implementing virtual network devices that utilize a Layer 2 protocol to transfer data between computing resources, storing local and remote VLAN addresses in a data structure to enable efficient packet routing and scaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard network devices are used to manage communications between VMs, then basic network functionality is maintained, but the system cannot scale to handle large numbers of VMs
Solution Approach 1:
The patent introduces a virtual network device as an intermediary component between VMs and physical network infrastructure. This virtual device manages Layer 2 communications by maintaining address mappings and routing decisions, offloading the complexity from standard physical network devices and enabling scalable VM communication.
Solution Approach 2:
The patent replaces traditional physical network device mechanisms with a software-based virtual network device that uses data structures (address mappings, routing tables) to manage communications. This substitution allows the system to scale beyond the hardware limitations of standard network devices.
2Quantity of substance
If standard network devices support thousands of VLANs and MAC addresses, then basic network capacity is achieved, but they still cannot manage communications between large numbers of VMs
Solution Approach 1:
The patent segments the network communication management function into a dedicated virtual network device that handles Layer 2 operations separately from VM creation. This segmentation allows the virtual device to maintain reliable communication management regardless of the total number of VMs, as it centrally coordinates address mappings and routing decisions.
3Adaptability or versatility
If virtual network devices are implemented to enable unlimited VM creation, then scalability is achieved, but new components and protocols are required
Solution Approach 1:
The virtual network device is designed as a universal component that handles multiple functions: maintaining address mappings, making routing decisions, managing VLAN communications, and supporting both local and remote network segments. This multi-functionality consolidates complexity into a single scalable component rather than requiring separate systems for each function.

AI summary
A device, of a cloud computing environment, includes a virtual network device that receives a packet with an address, and determines whether the packet is a broadcast packet or a unicast packet. The virtual network device processes the packet based on whether the packet is a broadcast packet or a unicast packet. The packet is transmitted to local address(es) or remote address(es) when the packet is a broadcast packet. The local address(es) is associated with at least one hardware component of the device, and the remote address(es) is associated with at least one other device, of the cloud computing environment, that is separate from the device. The packet is transmitted based on whether the address, of the packet, matches the local address(es) or the remote address(es) when the packet is a unicast packet.
