Utility
Path monitoring system (PMS) controller or ingress node based multiprotocal label switching (MPLS) ping and traceroute in inter-autonomous system (AS) segment routing (SR) networks
16 Jan 24
Echo or traceroute functionality is supported in a path spanning multiple autonomous systems (ASes) having segment routing (SR) enabled, the path including an ingress node and an egress node, by: (a) obtaining a return label stack to reach the ingress node from either (A) the egress node, or (B) a transit node in the path; (b) obtaining a label stack to reach, from the ingress node, either (A) the egress node, or (B) the transit node; (c) generating a request message including the return label stack; and (d) sending the request message towards either (A) the egress node, or (B) the transit node using the label stack.

Utility
Network policy generation for continuous deployment
9 Jan 24
In an example, a method comprises obtaining, by a policy controller from a first SDN architecture system, flow metadata for packet flows exchanged among workloads of a distributed application deployed to the first SDN architecture system; identifying, using flow metadata for a packet flow of the packet flows, a source endpoint workload and a destination endpoint workload of the packet flow; generating a network policy rule to allow packet flows from the source endpoint workload to the destination endpoint workload of the packet flow; and adding the network policy rule to a configuration repository as configuration data for a second SDN architecture system to cause a deployment system to configure the second SDN architecture system with the network policy rule to allow packet flows from the source endpoint workload to the destination endpoint workload when the distributed application is deployed to the second SDN architecture system.
