Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks lack the adaptability to differentiate and prioritize various types of traffic effectively, such as video streaming, web browsing, and self-driving automobile data, which requires specific latency and bandwidth requirements, due to limitations in existing 4G and 5G standards.
Innovation Solution
The establishment of a virtual service network across datacenters, utilizing network slices with customizable network services, where a network slice selector processes and routes data messages through appropriate network services based on traffic type and device characteristics, implemented using virtual machines, containers, or hardware forwarding elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 4G and 5G standards are used for traffic differentiation, then basic traffic classification is achieved, but adaptability to different device types and applications is insufficient
Solution Approach 1:
The network is segmented into multiple network slices, each optimized for specific traffic types (e.g., enhanced mobile broadband, ultra-reliable low-latency communications, massive machine-type communications). This segmentation allows differentiated service levels while maintaining a unified underlying infrastructure, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent implements a universal network slice selection function that can handle multiple device types and application scenarios through a single standardized interface. This multi-functional approach enables the network to adapt to diverse traffic requirements without requiring separate specialized systems for each application, thus improving versatility while controlling complexity.
2Adaptability or versatility
If network slicing is implemented to provide adaptable traffic management, then traffic differentiation capability is improved, but network configuration complexity increases
Solution Approach 1:
The patent introduces a network slice selection function as an intermediary component that automatically matches traffic requests with appropriate network slices based on predefined policies and traffic characteristics. This intermediary layer abstracts the complexity of network slice management from end devices and simplifies the configuration process while maintaining high adaptability.
Solution Approach 2:
The patent utilizes QoS parameter changes to dynamically adjust network slice characteristics based on traffic requirements. By modifying parameters such as bandwidth, latency, and reliability thresholds, the system can adapt to different application needs without requiring complex manual reconfiguration, thus balancing adaptability with configuration simplicity.

AI summary
Some embodiments provide a method for establishing multiple virtual service networks over multiple datacenters. The method configures, for each virtual service network of the plurality of virtual service networks, a set of machines distributed across the datacenters to implement an ordered set of network services for the virtual service network. The method configures multiple service network selectors executing within the datacenters to receive a data message, select one of the virtual service networks for the data message based on analysis of contents of the data message, determine a location within the datacenters for a machine implementing a first network service of the ordered set of network services for the selected virtual service network, and transmit the data message to the machine implementing the first network service.
