Feature peer network representations and scalable feature peer network management

A device, comprising:

• one or more processors to:
• receive packets of an application flow,
• inspect one or more of the packets of the application flow,
• determine, based on inspecting the one or more packets, a service graph of feature peers for the packets of the application flow,
• the feature peers being associated with a network,
• create a representation of the service graph,
• the representation of the service graph including an ordered set that includes a first notation for an ingress point of the packets, second notations for the feature peers, and a third notation for an egress point of the packets,
• provide the representation of the service graph to a controller device,
• the controller device configuring, based on the representation, the network with the service graph so that the packets of the application flow traverse the service graph,
• receive, from another device, instructions to establish a modified service graph that excludes
• a failed feature peer of, the feature peers and includes a backup feature peer for the failed feature peer,
• modify, based on the instructions, the service graph to obtain a modified service graph that includes the backup feature peer and excludes the failed feature peer, and
• create a representation of the modified service graph,
• the representation of the modified graph including the first notation for the ingress point of the packets, one or more of the second notations for one or more of the feature peers, a fourth notation for the backup feature peer, and the third notation for the egress point of the packets, and
• the one or more of the feature peers not including the failed feature peer.

A method, comprising:

• receiving, by a device, feature peer state information,
• the feature peer state information being received from a set of feature peers in a service graph associated with a user device of a customer;
• receiving, by the device, customer state information,
• the customer state information being generated by the user device;
• receiving, by the device, an indication of a failure of a particular feature peer in the service graph;
• instructing, by the device and based on the indication, a backup feature peer to retrieve the feature peer state information and the customer state information;
• and
• instructing, by the device and based on the indication, a traffic steering application (TSA) to establish a modified service graph that includes the backup feature peer and excludes the particular feature peer,
• the TSA being implemented on one or more other devices, and
• the one or more other devices being separate from the device.

A device, comprising:

• one or more processors to:
• receive feature peer state information from a set of feature peers in a service graph associated with a user device of a customer,
• receive customer state information generated by the user device,
• provide duplicates of the feature peer state information and the customer state information in a backup storage device,
• receive an indication of a failure of a particular feature peer in the service graph,
• instruct, based on the indication, a backup feature peer to retrieve the feature peer state information and the customer state information, and
• instruct, based on the indication, a traffic steering application (TSA) to establish a modified service graph that includes the backup feature peer and excludes the particular feature peer,
• the TSA being implemented on one or more other devices, and
• the one or more other devices being separate from the device.
