AI Technical Summary
Current Flex-algo protocols do not consider deterministic networking technologies, failing to meet requirements for deterministic delay calculation and reporting, especially in terms of end-to-end deterministic delay upper limits, packet loss rate, and delay variation, which are essential for deterministic service requirements such as low delay variation and low packet loss rate.
A method and apparatus for deterministic routing calculation that includes receiving an Flex-algo policy configuration message and sending a flooding message to network devices to instruct them to calculate paths based on deterministic routing policies, using extended IGP/BGP-LS protocols to implement deterministic delay variation and topology constraints, ensuring low delay variation and low packet loss rates.
The solution provides deterministic resources and paths for deterministic networks, meeting service requirements of low delay variation and low packet loss rates by implementing Flex-algo-based deterministic path calculation and reporting.
