An example method for performing application recognition in the cloud to support application-aware functionality on customer premises equipment includes detecting a data flow associated with a customer premises equipment device, identifying an application associated with the data flow, generating a mapping that maps the application to an identifier, and providing the mapping to the customer premises equipment device.

Cloud-based application recognition to support application-aware functionality on customer premises equipment

In one example, the present disclosure describes a device, computer-readable medium, and method for providing estimated bandwidth ranges to network-attached entities such as applications, user endpoint devices, and customer premises equipment. For instance, in one example, a method performed by a processing system including at least one processor includes collecting performance data for a communications network from a plurality of sensors distributed throughout the communications network, calculating based on the performance data, an estimated lower limit of an available bandwidth in the communications network and an estimated upper limit of the available bandwidth in the communications network, receiving a query from a network attached entity for the available bandwidth in the communications network, and providing, in response to the query, the estimated lower limit and the estimated upper limit to the network attached entity.

Providing estimated bandwidth ranges to network-attached entities

An architecture related to notifying user equipment of communication transportation functionality and/or facility shifts between a wired communication transportation framework and a wireless communication transportation framework. A method can comprise determining a decrease in a number of data packets flowing through a wireline network interface over a defined period of time, based on the number of data packets, determining that the wireline network interface is failing, generating a notification comprising a data record comprising a field representing a state associated with the failing wireline network interface, and sending the notification to a user equipment.

Converged cellular backup cost savings

An example method for controlling customer premises equipment via the cloud or network edge to support advanced network functionality includes detecting a data flow associated with a customer premises equipment device, identifying an application associated with the data flow, monitoring a performance of the application, determining an action to be taken by the customer premises equipment device to optimize the performance of the application, and sending an instruction to the customer premises equipment device to take the action.

Controlling customer premises equipment via the cloud or network edge to support advanced network functionality

Architectures and techniques are presented that can leverage network equipment (e.g., broadband provider equipment, cellular provider equipment) in order to provide enhanced guidance to a target location. This enhanced guidance can supplement existing mapping or navigation equipment. Such can be advantageous for public safety answering point entities and first responder entities as well as, potentially, for service technicians or delivery. When an entity (e.g., first responder) is dispatched to a particular location, an associated residential gateway (RG) or other device can be identified, and an associated SSID determined. This SSID can be provided to the entity seeking that particular location so that SSID scans can operate similar to a transponder or homing beacon. The SSID might also be configured specially for this purpose. Additionally, the state of a device attached to the RG can be altered to further aid in locating, such as blinking porch lights or audible indicia.

Guidance to a target location

A routing structure is defined for provider edge (PE) routers that will create the ability to recompute best paths based on application criteria. The routing structure may include the use of a network controller which is connected with the internet to receive requests from applications to trigger path re-computation. The controller will peer with PEs to send re-computation information used by the PE to construct an application-aware BGP table and forwarding instance. The PE also defines a new BGP and packet filter to replicate specific BGP paths into the application-aware table. The application-aware BGP and forwarding instance is unique to the requesting application. Thus, each request with a different source/destination combination obtains a discrete table providing separation. When a packet enters the PE from customer edge (CE) or core interface the packet traverses a packet filter that when matched against source/destination is redirected to the appropriate application-aware forwarding table. Once in the application-aware table the packet is then forwarded along the application-aware path achieving the objective. The instantiation of the application-aware BGP and forwarding table is be done based on BGP updates learned from the controller.

Application-aware BGP path selection and forwarding

Aspects of the subject disclosure may include, for example, receiving network performance metrics for a plurality of paths through a network, each path extending from a customer equipment to an application server for data communication by the customer equipment with an application running on the application server, selecting a selected path among the plurality of paths, wherein the selecting is based on the network performance metrics, and communicating between the customer equipment and the application server according to the selected path. Border gateway protocol (BGP) community values (BGP CV) add BGP performance metrics community values (BPM CV) to convey network performance metrics to provider edge routers and customer premises equipment for network selection. Other embodiments are disclosed.

Dynamic network metric sharing and application metric based network path selection

A method includes receiving a request to initiate an emergency call, directing, the mobile device to initiate the emergency call using a cellular network, receiving a network not available indication that the emergency call cannot be completed using the cellular network, selecting location information of the mobile device and requesting the emergency call be initiated by a VoIP client on the mobile device using the location information obtained from the selecting step.
