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.
