A device may receive explicit congestion notification data associated with user devices connected to a network of network devices, and may receive network data identifying network metrics associated with the network devices. The device may generate an active queue management mapping table based on utilizing a model to process the explicit congestion notification data and the network data. The device may determine, based on the active queue management mapping table and the network data, a routing table that includes routing data identifying traffic paths with active queue management enabled network devices and without non-active queue management enabled network devices of the network devices. The device may provide the routing table to the network devices.

Systems and methods for determining routing data based on explicit congestion notifications and active queue management enabled network devices

A controller determines a first path across a first segment routing (SR) domain and a second SR domain to a destination in the second SR domain, where the first SR domain uses a first SR protocol and the second SR domain uses a second SR protocol. The controller determines SR instructions that enable the interworking of the first SR domain and the second SR domain when data is routed across the first path to the destination. The controller sends, prior to the data being routed over the first path, the SR instructions to at least one of a first router in the first SR domain, a second router in the second SR domain, or a third router in the first SR domain to enable the interworking of the first and the second SR domains for segment routing the data across the first path.

Systems and methods for SR-MPLS to SRv6 interworking

A device may provide path data identifying a primary path and one or more alternate paths for segment routing traffic in the network, and may receive performance data indicating a performance degradation in the primary path. The device may determine that the performance data satisfies a first threshold, and may request, based on the performance data satisfying the first threshold, alternate path performance data. The device may receive the alternate path performance data based on the request, and may compare the alternate path performance data for the one or more alternate paths. The device may select a particular alternate path, of the one or more alternate paths, based on comparing the alternate path performance data for the one or more alternate paths, and may trigger, based on the performance data satisfying a second threshold, a failover of the traffic from the primary path and to the particular alternate path.

Systems and methods for utilizing segment routing over an internet protocol data plane for latency metrics reduction

A controller determines a path from a first router in a first segment routing (SR) domain to a destination in a second SR domain, where the path includes a first sub-path in the first SR domain and a second sub-path in the second SR domain. The controller determines first SR instructions, that conform to a first SR protocol, for the first sub-path, and determines second SR instructions, that conform to a second SR protocol, for the second sub-path. The controller sends the first SR instructions to the first router in the first SR domain to enable segment routing of data towards the destination via the first sub-path, and sends the second SR instructions to a second router located at an end of the first sub-path or at a beginning of the second sub-path to enable segment routing of data towards the destination via the second sub-path.
