A controller, in a software-defined networking control layer, may determine auto-discovery parameters and may use the auto-discovery parameters to identify a first set of forwarding boxes within a network. The controller may identify a second set of forwarding boxes within the network that communicate with or are otherwise coupled to the first set of forwarding boxes. The controller may forward requests to the first and second sets of forwarding boxes to control traffic exchanged via the first and second sets of forwarding box. A third set of forwarding boxes located outside the network may request admissions into the software defined network, and requests from the third set of forwarding boxes may be forwarded to the controller via the first or second sets of forwarding boxes. The controller may authenticate the second and the third sets of forwarding boxes based on their relationship to the first set of forwarding boxes.

Discovery and admission control of forwarding boxes in a software-defined network

A controller network device receives command input for providing services over a service provider network and receives a verification request to verify an initial output of a control communication sent to a forwarding network device by a second controller network device in a group of peer controller network devices. The controller network device receives, from other controller network devices in the group of peer controller network devices, results that are responsive to the verification request and based on the command input and identifies a majority output from the results. The controller network device compares the initial output from the second controller network device to the majority output to determine that the initial output failed a verification vote and determines when a threshold number of control communications from the second controller network device, including the initial output, have failed verification votes.

Network element federation controller and forwarding box

A method may include receiving a request to provide at least one application session, and generating a networking architecture that includes at least one virtual route reflector front end (VRR FE), at least one back end work unit, and at least one routing information base (RIB) in a virtualization environment. The method includes implementing the at least one application session via the at least one VRR FE, the at least one back end work unit, and the at least one RIB. The at least one VRR FE is to perform as a proxy for traffic to the at least one back end work unit. The method also includes monitoring a load associated with the at least one application session, and performing load balancing on the networking architecture based on assignment of the load to the at least one back end work unit.

Networking functions in a micro-services architecture

A method, a device, and a non-transitory storage medium to receive a job request to schedule an execution of a process in a networked environment; generate a schedule for the execution of the process based on one or more current schedules directed to concurrent execution of one or more other processes; obtain resource utilization data indicating resource usage stemming from the concurrent execution of the process and the one or more other processes; analyze the resource utilization data; determine whether a resource inefficiency occurred during the concurrent execution based on an analysis of the resource utilization data; generate resource inefficiency data in response to a determination that the resource inefficiency occurred; and generate an adapted schedule for at least one of the process or the one or more other processes in response to a determination that the resource inefficiency occurred.

Adaptive scheduling and orchestration in a networked environment

A device may receive a request to establish a connection between a first device and a second device. The request may include information identifying a network connectivity type. The device may determine one or more network devices to provision based on the network connectivity type; determine, based on the network connectivity type, provisioning parameters used to provision the one or more network devices; and provision the one or more network devices in accordance with the provisioning parameters to establish the connection between the first device and the second device.

Provisioning network devices based on network connectivity type

A controller network device, in a network control layer of a service provider network, receives one or more parameters for providing particular services over a service provider network and provides, to a forwarding network device in a network resources layer of the service provider network, a capabilities query. The capabilities query includes a feature type identifier for a feature required to support the parameters. The controller network device receives, from the forwarding network device, a response to the capabilities query, wherein a format for the response is one of a binary response format, a conditional response format, or a value response format. The controller network device compiles the response with responses from other forwarding network devices to define a network map for supporting the particular services.

Controller supported service maps within a federation of forwarding boxes

A controller network device, in a network control layer of a service provider network, receives command input for providing services over a service provider network and provides, to a forwarding network device, a first control communication. The first control communication includes an initial output to implement the command input. The controller network device provides, to peer controller network devices, a verification request to verify the initial output of the first control communication; receives, from the peer controller network devices, responses to the verification request that each include a calculated output based on the command input; and applies a verification schema to determine a majority output from the responses. The controller network device compares the initial output to the majority output and sends a second control communication, with a verified output indication, to implement the command input when the initial output matches the majority output.

An intelligent network interconnect may include a control channel and a plurality of nodes. The plurality of nodes may include a first node coupled to a first network and a second node coupled to a second network. Each of the plurality of nodes is coupled to the control channel. The intelligent network interconnect may also include a control device coupled to the control channel. The intelligent network interconnect may be configured to: collect network data from the first node and the second node, wherein the network data includes traffic data of the first network; obtain metrics based on the collected network data; detect an event based on the metrics and the collected network data; and a rule whose condition matches the event; and send a command over the control channel, to one or more of the nodes, to perform an action associated with the rule.

A server may receive flow information from multiple network devices. The flow information may include information regarding multiple data flows received by the multiple network devices and destined for a client device. The server may determine generate an optimization instruction, based on flow information, to re-route one or more of the plurality of data flows or to apply filters to the one or more of the plurality of data flows; provide the optimization instruction to cause one or more of the multiple network devices to re-route one or more of the multiple data flows or to apply filters to the one or more data flows to alleviate overloaded network components or to re-route network resources to or from the client device; receive updated flow information after receiving the flow information; generate an updated optimization instruction based on the updated flow information; and provide the updated optimization instruction.

Dynamic filtering and load optimization instructions based on subscribtion and real-time network and service load data

A network device may be configured to define a Layer 2 domain, wherein the Layer 2 domain defines a data link layer broadcast domain and assign an access interface to the Layer 2 domain. The network device may be further configured to assign a double Virtual Local Area Network (VLAN) identifier to the access interface in the Layer 2 domain, wherein the double VLAN identifier includes an inner VLAN identifier and an outer VLAN identifier, receive a data unit via the access interface, wherein the data unit includes the double VLAN identifier, and associate the data unit with the defined Layer 2 domain, based on the data unit being received via the access interface and based on the data unit including the assigned double VLAN identifier.
