Various embodiments disclosed herein provide for data traffic steering based on quality of service. According to some embodiments, a system can comprise receiving data packets associated with a quality of service value, wherein the data packets are stored in a buffer and transmitted utilizing a first link, determining whether a condition that indicates a modification to a data routing schedule is satisfied and whether a second link is available, and in response to the determining indicating that the condition is satisfied and that the second link is available, performing the modification of the data routing schedule comprising utilizing the second link and the first link to transmit the data packets associated with the quality of service value.

Aspects of the subject disclosure may include, for example, initiating emergency QoS measures in a RAN cell responsive to detecting an emergency condition applicable to the RAN cell, identifying, among a plurality of wireless communication devices served by the RAN cell, a set of non-emergency devices, identifying, among the set of non-emergency devices, one or more carrier aggregation (CA)-prone devices, and applying an updated buffer threshold value for a CA-prone device among the one or more CA-prone devices, to reduce a likelihood of initiation of carrier aggregation for the CA-prone device. Other embodiments are disclosed.

A method and apparatus for monitoring connectivity in a network at a bearer path layer are disclosed. For example, the method receives a request to monitor a user endpoint, identifies an internet protocol address of the user endpoint, an internet protocol address of each transport network element between the user endpoint and a bearer trace server, a bearer path identification of each bearer used by the user endpoint, a quality of service associated with each bearer used by the user endpoint, and a tunnel identification of each bearer used by the user endpoint; and performs a fault isolation and performance monitoring at a bearer path layer, wherein the fault isolation identifies a particular segment where a fault is detected at the bearer path layer.

Method and apparatus for monitoring connectivity in a long term evolution network

A system that incorporates the subject disclosure may include, for example, accessing configuration information, monitoring for radio resource control connection requests being transmitted from the wireless communication device to a first server of a first cell of a network, determining whether failed radio resource control connection requests satisfy a cell barring threshold based on the monitoring and based on the configuration information, and responsive to a determination that the cell barring threshold has been satisfied, causing the wireless communication device to perform cell selection for a second cell of the network and to perform cell barring of the first cell. Other embodiments are disclosed.

Apparatus and method for management of radio resource control connections

Systems and methods of automatically determining a set of route targets is provided. The method includes receiving network topology data specifying configuration of a network. The method also includes automatically converting the network topology data into route targets to be assigned to virtual routing and forwarding elements. The route targets are grouped into sets and duplicate sets of route targets are removed. The method further includes generating a data record including information related to the set of route targets.

System and method to provision an MPLS/VPN network

A method for delivering targeted advertisement data to opt-in subscribers in an internet protocol television (IPTV) system is disclosed, the system comprising selecting an advertising target group of opt-in IPTV subscribers based on an advertiser's advertising target request; and multicasting an advertisement from an IPTV advertising server to the advertising target group. A system for performing the method is disclosed.

A method includes receiving a selection of a channel at a set-top box device. In response to the selection of the channel, a still image associated with a program is displayed at a display device. The method further includes receiving a multicast stream of video content associated with the selected channel at the set-top box device. At least a portion of the multicast stream is received while the still image is displayed at the display device. The method also includes transmitting the video content to the display device.

Communicating video content

Systems and methods of automatically determining a set of route targets is provided. The method includes receiving network topology data specifying configuration of a network. The method also includes automatically converting the network topology data into route targets to be assigned to virtual routing and forwarding elements. The route targets are grouped into sets and duplicate sets of route targets are removed based on the route targets between duplicate sets of route targets identified as being the same. The method further includes generating a data record including information related to the set of route targets.

System and method to provision MPLS/VPN network

A method is disclosed that includes receiving a selection of a channel at a set-top box device. In response to the selection of the channel, a still image associated with a program being transmitted via the selected channel is displayed at a display device. The method further includes receiving a multicast stream of video content associated with the selected channel at the set-top box device. At least a portion of the multicast stream is received while the still image is displayed at the display device. The method also includes transmitting the video content to the display device.

Policy-based routing of packets over a peer-to-peer, quality of service connection includes sending a connection setup request, over a control connection to a connection establishing device, to dynamically establish the peer-to-peer, quality of service connection between a source peer implemented on at least one device and a destination peer implemented on at least one device. Packets originating from an application requiring a specified level of service are transmitted, from the source peer implemented on at least one device, over the peer-to-peer, quality of service connection. Packets originating from an application that does not require the specified level of service are transmitted, from the source peer implemented on at least one device, over a best effort connection.
