In one embodiment, a network element in a network receives one or more machine learning models configured to make an inference about the network. The network element requests, according to a predefined peering plan, telemetry attribute data from one or more peer network elements specified by the peering plan. The network element receives the telemetry attribute data from the one or more peer network elements. The network element makes, using the one or more machine learning models, an inference about the network based in part on the received telemetry attribute data.

Embodiments of the present invention relate to the communications field, and provide a multi-chassis cascading apparatus. The apparatus includes a line card chassis LCC, where a fabric interface chip FIC and a switch element SE 1/3 are deployed in each line card chassis LCC; the fabric interface chip FIC is connected to the switch element SE 1/3 that is located in the same line card chassis LCC as the fabric interface chip FIC is; and a switch element SE 2 is deployed in each line card chassis LCC; the switch element SE 1/3 is connected to the switch element SE 2 that is located in the same line card chassis LCC as the switch element SE 1/3 is; and the switch element SE 1/3 is connected to the switch element SE 2 that is located in another line card chassis LCC.

A router node comprises a link discovery module, a security module, a secure access module and storage. The link discovery module discovers a link to an adjacent router node and receives its first loopback address. The link discovery module creates a first tunnel between the security module in the router node and the first loopback address. The security module receives a second loopback address for the second router node, and creates a second tunnel. The security module repeats the discovering, receiving and creating steps for each router node adjacent to the first router node. The storage separately stores a link discovery routing table which comprises information relating to the links between the router node and each adjacent router note; a security routing table which stores the unique first loopback address; and a secure access routing table which stores the unique second loopback address.

This application provides a method for deciding on handling a failure of a stacking system, where the method includes: collecting values of a decision parameter for respective groups after the stacking system is divided; and applying a preset reserve strategy according to the values of the decision parameter for the respective groups to decide on one of the groups to be reserved.

An electronic device and other electronic device include a first and second port that utilizes a parallel redundancy protocol in a communications network including a first and second lane. The devices include a processing circuit, a PRP handler, a protocol stack, a memory, permanent storage accessible by the processing circuit, and transmit and receive circuitry for transmitting and receiving packets. A redundancy manager is for identifying path faults in the network. The processing circuit implements a method of detecting network path fault, including the other electronic device transmitting a frame pair over the first lane and second lane. The electronic device receives the frame pair and implements a receive processing flow, when the first frame or the second frame is identified to be a redundant frame, removes the redundant frame, and compares a first frame parameter to a second frame parameter to determine when the path fault is present.

The deployment and scaling of a network of electronic devices can be improved by utilizing one or more network transpose boxes. Each transpose box can include a number of connectors and a meshing useful for implementing a specific network topology. Different tiers of a network can be connected to one or more of the network transpose boxes, and operated as a logical switch. A control server can be used to manage the control plane operations of the logical switch.
