Segment Routing Service Attribute Flooding for Flexible Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing segment routing (SR) networks face challenges with single-sided data distribution and low flexibility in service data transmission, hindering flexible deployment and scheduling.
Innovation Solution
A method and apparatus for segment routing service processing that involves acquiring and flooding service attribute information across the network, allowing any node to report this information to the control plane, and utilizing SR proxy nodes to simplify service logic and enhance data distribution and transmission flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If each node reports SR service data to the control plane through the node corresponding to the SR service data, then the control plane can orchestrate each SR service, but the data distribution becomes single-sided and transmission flexibility is reduced
Solution Approach 1:
The patent introduces a service attribute information reporting mechanism where nodes can report service attribute information to the control plane through any node in the network, not just the node corresponding to the SR service data. This intermediary reporting mechanism enables the control plane to obtain comprehensive service information while allowing flexible data distribution paths through the network.
Solution Approach 2:
The patent extends the traditional single-node reporting model to a multi-node reporting dimension. By allowing nodes to report service attribute information through different nodes in the network, the system creates multiple information transmission dimensions, thereby improving both control plane orchestration capability and transmission flexibility simultaneously.
2Loss of information
If service attribute information is reported through a single node, then the control plane can obtain service data, but the distribution of SR service data becomes limited
Solution Approach 1:
The patent makes any node in the network capable of reporting service attribute information to the control plane. This universal reporting capability ensures that service data can be obtained through multiple paths and nodes, improving both information availability and data distribution capability across the network.
3Extent of automation
If SR service data is distributed through a fixed path, then the control plane can manage the network, but the scheduling flexibility is reduced
Solution Approach 1:
The patent introduces dynamic service attribute information reporting where nodes can report service information through different paths and nodes based on network conditions. This dynamic reporting mechanism allows the control plane to manage the network while maintaining high scheduling flexibility, as the reporting paths can adapt to different network states.
