The system includes a computer device programmed to: a) store plurality of records for a plurality of network elements, wherein each record of the plurality of records includes a current status of the corresponding network element of the plurality of network elements; b) receive a request for a set of network elements for data transmission; c) scan the plurality of records for a plurality of available network elements for the request; d) select a first set of network elements to meet the request from the plurality of network elements based upon the current status of each of the plurality of available network elements; e) generate a response to the request based upon the first set of network elements; f) receive a confirmation of the response; and g) configure the first set of network elements to complete the data transmission.

A communication method, a communication apparatus, and a communication system includes: A first device determines first hop count information, where the first hop count information indicates a quantity of relay devices of the first device, and the first device is connected to a network device via the relay device. The first device determines, based on the first hop count information, whether to send a first message, where the first message indicates the first device to provide a relay service. A better relay service can thus be provided for a remote device.

A communication method, apparatus, and system, where the method includes: A visited policy control network element updates a first service parameter to a second service parameter based on a mapping relationship between first network slice identification information of a visited network and second network slice identification information of a home network, where the first service parameter includes the first network slice identification information of the visited network, and the second service parameter includes the second network slice identification information of the home network; and the visited policy control network element sends the second service parameter to a home policy control network element, where the second service parameter is used to determine a user route selection policy for a terminal device.

Techniques are disclosed for reporting diagnostics data by a first network device to a cloud-based Wide Area Network (WAN) assurance system, responsive to the first network device detecting a communication issue with the cloud-based WAN assurance system. For example, the first network device detects an issue with sending telemetry data to the cloud-based WAN assurance system via a first communication path. In response, the first network device determines a second network device that has connectivity to the WAN assurance system. The first network device sends diagnostics data to the second network device along a second communication path for forwarding to the cloud-based WAN assurance system. The cloud-based WAN assurance system receives the diagnostics data from the second network device. The cloud-based WAN assurance system controls the second network device to remediate the first network device based on the diagnostics data.

To determine a communication path satisfying communication requirements depending on an operation of an application, it is provided a management device for selecting a communication path that satisfies communication requirements for an application operating on a terminal, the management device comprising: an event detection module configured to detect, as an event, one of an operation change, an increase, or a decrease of the application which is accompanied by a change in the communication requirements; app information for managing the communication requirements for each operation of the application; communication path information for managing communication quality of each communication path; and a communication control method calculation module configured to determine, by referring to the app information and the communication path information, a communication control method that satisfies the communication requirements for the application from which the event has been detected, and notify a communication control device of the determined communication control method.

Aspects of the subject disclosure may include, for example, identifying a current communication path and a group of alternate communication paths extending between the first and second communication devices. The current communication path is configured to support exchanges of information between the first and second communication devices according to a communication service. A partial degradation of the current communication path is detected according to a first degradation severity rating and responsive to the detecting, the first degradation severity rating is compared to a group of alternate degradation severity ratings each corresponding to a respective alternate communication path of the group of alternate communication paths. An alternate communication path of the group of alternate communication paths is selected, for the communication service, having a second degradation severity rating less than the first degradation severity rating. Other embodiments are disclosed.

Systems, methods, and apparatuses are disclosed for selecting a directional Software Defined Wide Area Network (SD-WAN) transport/stream to transmit packets of a unidirectional Internet Protocol (IP) flow over one or more WAN transports between an SD-WAN router and an SD-WAN gateway. In one example, the SD-WAN router and the SD-WAN gateway maintain a multitude of SD-WAN tunnels on at least two different types of WAN transports (such as, e.g., a satellite-based, a cellular telecommunication-based, and/or an Internet-based type). Each SD-WAN tunnel has an upstream directional SD-WAN transport/stream and a downstream directional SD-WAN transport/stream. In one example, an SD-WAN device receives packets to transmit in a specific direction on an SD-WAN communication connection and selects, to transmit the received packets, a directional SD-WAN transport/stream from among the active directional SD-WAN transport/streams in that specific direction on all of the WAN transports, based on its operational status (e.g., CLEAN, BROWNOUT, or BLACKOUT).
