An apparatus and method for the monitoring of performance metrics at links located within the communication network. A method may include discovering multiple paths across a plurality of nodes in a network between a user equipment and an endpoint. The method may also include deriving at the user equipment performance metrics of an edge located between two of the plurality of nodes. The performance metrics is derived based on performance of the two nodes bordering the edge. The two nodes are located within one of the multiple paths.

Network link performance

Various embodiments pertain to communication network systems. In particular, various embodiments relate to multi-path probing in communication network systems that can be used to estimate the complete topology of the network. A method includes receiving data at a source node from a tracerouting probe in the network. The tracerouting probe detects edges. The method also includes calculating an edge completion ratio based on the edges. In addition, the method includes terminating the probe when the edge completion ratio is greater than or equal to a threshold.

Path probing using an edge completion ratio

An apparatus and method for a service network status in a communication network are provided. A method may include deriving a baseline or a threshold for network performance of at least one endpoint in a network. The method may also include evaluating a service network status of the network by comparing current performance metrics of the at least one endpoint to the baseline or the threshold. In addition, the method may include determining, when the evaluated service network status is degraded, at least one node or at least one link that is causing the service network status to be degraded using a root cause analysis.

Network status evaluation

A method includes detecting a first path between a user equipment and a first network entity. The method also include detecting a second path between the user equipment and a second network entity, where the first path is longer than the second path. In addition, the method includes determining whether the second network entity is a proxy server located between the user equipment and the first network entity based on an estimated value of the first path and an estimated value of the second path.

Network proxy detection

Various embodiments pertain to communication network systems. In particular, various embodiments relate to multi-path probing in communication network systems that can be used to estimate the complete topology of the network. A method includes receiving data at a source node from a tracerouting probe in a network. The data includes information about at least one network node. The method also includes determining an identification for the at least one network node based on information. In addition, the method includes using the identification of the at least one network node to determine an identification of at least one device.
