Using a routing protocol for network port failover. A network stack, which does not perform reverse path forwarding, includes a first interface as a loopback interface that is assigned a first internet protocol (IP) address, a second interface to a first network port, and a third interface to a second network port. The routing protocol is configured to communicate over the second interface with a first port at remote network device(s), and to communicate over the third interface with a second port at the remote network device(s). A route comprising the first IP address is announced to the remote network device(s), and default route of the network stack is configured to egress IP packets via the second interface. Later, the routing protocol indicates that there is a forwarding failure associated with the second interface, and the default route is configured to egress IP packets via the third interface.

A method may include receiving a data flow of an application directed to the destination in a software-defined network (SDN). The method may also include identifying a classification of the application. The method may additionally include identifying a set of performance thresholds associated with the classification of the application. The method may also include determining a current performance of the data flow of the application in the SDN. The method may also include generating a performance score for the application based on the set of performance thresholds and the current performance of the data flow of the application in the SDN. The method may further include causing the performance score for the application to be presented via an interface.

Example methods and systems for logical network packet handling are described. In one example, a physical network interface controller (PNIC) may receive an egress packet associated with a packet flow via a first virtual function supported by the PNIC. The PNIC may steer the egress packet towards a processing pipeline by applying a filter associated with the first virtual function or content of the egress packet, or both. The egress packet may be processed using the processing pipeline to generate a processed packet by (a) retrieving a logical network policy associated with the packet flow from a datastore on the PNIC and (b) performing one or more actions according to the logical network policy. The processed packet may be forwarded towards the destination via a second virtual function supported by the PNIC or a physical network connected to the PNIC.

A Service Routing Agent and methods are disclosed that classify and route data service requests. One embodiment includes a control circuit and at least one orchestrator, processor, and service handler circuit. The control circuit performs a process to: receive a configuration of at least one service handler circuit, initialize a list of service handler circuits and associated applications, program the at least one processor to listen for data service requests associated with the application, receive a data service request, and determine whether a service handler circuit associated with the application has been activated; when the service handler circuit has been activated, forwards the data service request to the service handler circuit, and when the service handler circuit has not been activated, request that the service handler circuit be activated, and then forwards the data service request to the service handler circuit. The Service Routing Agent reports updated traffic statistics.

A routing control method is performed by a computer device acting as an intelligent routing server in an accelerated cloud network, the method including: receiving a routing query request sent by one forwarding node in the accelerated cloud network, the routing query request being generated by the forwarding node according to an access request for a target node by a terminal device; obtaining path information of a forwarding path according to state information of forwarding nodes in the accelerated cloud network, the forwarding path being used to forward the access request in the accelerated cloud network; and transmitting the path information to the forwarding node, wherein the forwarding node is configured to forward the access request to the target node according to the path information.

Optimal determination of wireless network pathway configurations may be provided. A computing device may receive an error profile and a response instruction associated with the error profile, as generated by a network controller. The computing device may then monitor, for an error, on a communication Track, in a network, between an ingress node and an egress node. Then, the computing device, upon detecting the error, can determine that the error is similar to the error profile, and based on the determination that the error is similar to the error profile, enact the response instruction. The response instruction can direct the computing device to switch from the communication Track to a communication subTrack between the ingress node and the egress node.

Methods, systems, and computer readable media for routing a Diameter message are disclosed. According to one method, the method occurs at a Diameter routing node. The method includes receiving, from a Diameter routing controller (DRC) via a software defined network (SDN) related interface, Diameter routing information, wherein the Diameter routing information is determined using application layer information. The method also includes routing a Diameter message using the Diameter routing information.

A method and system for configuring a fifth generation (5G) network may include utilizing software-defined networking (SDN) for separating a data plane from a control plane of a 5G network. The separated control plane may be run across a low earth orbit (LEO) system between an edge network and a core network of the 5G network such that the LEO system exclusively directs the control plane. A pathway for the data plane may be determined and generated by the LEO system exclusively using the control plane. In some examples, SDN control may be established exclusively on a LEO system based on a service request. A pathway for the data plane from a first location to a second location may be determined and generated based on the service request and the control of the control plane on the LEO system.
