Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for computing and communication instance selection in 6G Wide Area Clouds lack efficient end-to-end and per-hop measurement collection capabilities, limiting the ability to make informed decisions about computing and communication resources.
Innovation Solution
The implementation of an updated Segment Routing Header (SRH) format with additional fields for measurement collection, including a unique transaction ID and indication fields, enables the collection of computing and communication-related measurements across the network, allowing for better decision-making and resource optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional routing headers are used without measurement fields, then device complexity is reduced, but measurement precision and information availability deteriorate
Solution Approach 1:
The measurement collection mechanism is nested within the existing Segment Routing Header structure by adding optional indicator fields and transaction ID fields. This allows measurement functionality to be embedded in the packet header without requiring separate measurement systems, thus improving measurement precision while minimizing additional complexity.
Solution Approach 2:
Measurement indicators and transaction IDs are embedded in the packet header at the source before transmission. This preliminary action enables intermediate routers to collect measurements without needing complex processing logic, as the necessary measurement data is already prepared in the packet structure.
2Loss of information
If detailed measurement collection is implemented across all hops, then information availability improves, but loss of time and processing overhead increase
Solution Approach 1:
The patent extracts only the essential measurement indicators (timestamps, hop counts) from the complex measurement collection process. By taking out only the necessary measurement data and placing it in the packet header, the system achieves good information availability without the time loss associated with collecting and processing extensive measurement data at each hop.
Solution Approach 2:
The patent implements partial measurement collection by using indicator fields that can be selectively enabled. Rather than collecting all possible measurements at every hop, the system collects only the specific measurements indicated by the indicator fields, reducing processing time while maintaining necessary information availability for computing instance selection.
3Productivity
If per-hop measurement collection is enabled, then productivity and decision-making quality improve, but device complexity and processing overhead increase
Solution Approach 1:
The packet itself carries the measurement information through indicator fields and transaction IDs embedded in its header. Intermediate routers simply read and forward these fields without needing complex processing, making the measurement collection system self-service and minimizing the complexity burden on network devices while improving productivity through better measurement data.

AI summary
A non-transitory computer-readable medium may include one or more instructions which, if executed by a processor of a node of a cellular network, cause the processor to: generate a segment routing header comprising information representative of a measurement enablement; and apply a segment routing of a packet within the cellular network based on the segment routing header.
