==Minimal SID depth for ring topologies in Segment Routing via a PCE and Flex-Algo - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18131210 titled 'Minimal SID depth for ring topologies in Segment Routing via a PCE and Flex-Algo

The patent application describes systems and methods for a Segment Routing network with multiple nodes in a ring.

* Defines a first Flexible Algorithm with constraints to direct traffic in one direction around the ring.
* Defines a second Flexible Algorithm with constraints to direct traffic in the opposite direction around the ring.
* A Path Computation Engine (PCE) groups links on computed paths to rings, determines direction on each ring, and assigns Flex-Algo SIDs to links for final nodes.
* Provides a SID list with Flex-Algo SIDs for rings to a source node in the Segment Routing network.

**Key Features and Innovation:**

* Utilizes Flexible Algorithms with constraints to control traffic flow in different directions around a ring network.
* Path Computation Engine optimizes routing paths by grouping links and assigning Flex-Algo SIDs for efficient traffic management.
* Enables precise control and optimization of traffic flow in Segment Routing networks.

**Potential Applications:**

* Telecommunications networks
* Data centers
* Internet service providers

**Problems Solved:**

* Efficient traffic management in ring networks
* Optimized routing paths
* Enhanced control over traffic flow

**Benefits:**

* Improved network performance
* Reduced congestion
* Enhanced scalability

**Commercial Applications:**

Segment Routing technology can be applied in various industries such as telecommunications, data centers, and internet service providers to optimize network performance, reduce congestion, and enhance scalability.

**Questions about Segment Routing Technology:**

1. How does the Path Computation Engine optimize routing paths in a Segment Routing network?
2. What are the main benefits of using Flexible Algorithms with constraints in directing traffic flow in a ring network?


==Original Abstract Submitted==

Systems and methods, associated with a Segment Routing network including a plurality of nodes in a ring, include defining a first Flexible Algorithm having one or more first constraints for links in the ring to force traffic to flow in a first direction around the ring; and defining a second Flexible Algorithm having one or more second constraints for of the links in the ring to force traffic to flow in a second direction around the ring. A Path Computation Engine (PCE) is configured to group links on the computed path to the one or more rings, for each ring, determine a direction on an associated ring and assign the grouped links on the associated ring with a Flex-Algo SID for a final node in the determined direction, and provide a SID list that includes the Flex-Algo SIDs for the one or more rings, to a source node in a Segment Routing network.
