Utility
Storing configuration data changes to perform root cause analysis for errors in a network of managed network devices
16 Jan 24
An example application programming interface (API) server device that distributes configuration data to managed network devices includes one or more processing units implemented in circuitry and configured to receive configuration data to be deployed to at least one of the managed network devices; store the configuration data to a configuration database; and send the configuration data to the at least one of the managed network devices.

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
Avoiding loops by preventing further fast reroute (FRR) after an earlier FRR
16 Jan 24
In some cases, once Fast Reroute (FRR) has taken place (e.g., for MPLS protection), a further FRR is undesirable, and even detrimental.

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.

Utility
Using anycast as an abstract next hop (ANH) to reduce information related to border gateway protocl (BGP) next hops received by autonomous system border routers (ASBRs) and/or to improve BGP path convergence
19 Dec 23
An autonomous system border router (ASBR) provided in a domain in which routers share an anycast address, may perform a method comprising: (a) receiving, from an exterior Border Gateway Protocol (eBGP) peer, first reachability information for a first prefix, the first reachability information including a first next hop (NH) address; (b) communicating first link state information about the first prefix to another router in the domain, the first link state information associating the first prefix with the anycast address; (c) receiving, from an eBGP peer, second reachability information for a second prefix, the second reachability information including a second next hop (NH) address; and (d) communicating second link state information about the second prefix to the other router in the domain, the second link state information associating the second prefix with the anycast address.
