An address obtaining method includes obtaining, by a third network device, an identifier of a first application from a terminal device. The identifier of the first application indicates a request for obtaining an address of an instance of the first application. The address obtaining method further includes sending, by the third network device, a first message to a first network device, wherein the first message comprises the identifier of the first application, and the first message is useable to request the address of the instance of the first application. The address obtaining method further includes receiving, by the third network device, the address of the instance of the first application from the first network device, and sending the address of the instance of the first application to the terminal device.

Presented herein are techniques for dynamic optical network programming using Segment Routing (SR) using an Optical Provisioning SR Label (OPSL). In one form, a method is provided that is performed by a network element that has received an OPSL from another network element to create an optical circuit. In another form, a method is provided that is performed by a network element that sends an OPSL to another network element to cause that other network element to create an optical circuit.

In one embodiment, a method includes establishing, by an identity agent installed on a device, a connection to a browser installed on the device and generating, by the identity agent, first device information, a public key, and a private key. The method also includes communicating, by the identity agent, the first device information and the public key to an authentication service and receiving, by the identity agent, a unique identifier from the authentication service. The method further includes generating, by the identity agent, a first signature of the first device information and communicating, by the identity agent, the first signature, the first device information, and the unique identifier to the browser.

Systems and methods are provided herein for a mechanism for faster convergence of network traffic after a network device's link is interrupted by leveraging the withdrawal of the ethernet virtual private network (EVPN) auto discovery (AD) route. This may be accomplished by a first device checking an ethernet segment identifier (ESI) status flag before generating an entry in the first device's forwarding table, where the entry is based on an IP route for a host received by a second network device. In response to receiving a withdrawal of an EVPN AD route from the second device, the first device may update the ESI status flag to indicate that the host on the ethernet segment (ES) is reachable only via the third device and update the entry that was based on the IP route for the host received by the second network device to prevent sending traffic to the host via the second device.

A master node, a local node, a service assurance system, and a respective method performed thereby for predicting one or more metrics associated with a communication network are provided. The method performed by the master node operable in the communication network comprises receiving prediction(s) based on training data from local nodes in the communication network; and determining weight parameter(s) associated with the local nodes based on the current received prediction(s) and past received predictions. The method further comprises adjusting a respective local reporting policy for one or more local nodes based on the determined weight parameter(s).

Systems, apparatuses, and methods may provide for robust and autonomous provisioning of routing nodes and/or server stacks within a network. For instance, each routing node and/or server stack may perform self-discovery (e.g., determines its own identity and where it has been placed in the network), and determine its role (e.g., how to route packets) within the network.
