Abstract: 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.

Abstract: 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.

Abstract: A method includes receiving, at a server, a retry request from a media device. The retry request requests a data packet associated with video content and includes an overhead bandwidth factor corresponding to a ratio between an overhead bandwidth to be used to send the data packet in response to the retry request and a nominal bandwidth used to send video content to the media device. The method further includes, in response to the retry request, sending the data packet to the media device based on the overhead bandwidth factor.
