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

A method and apparatus may include determining a root. The root includes a first node within a cluster of nodes of a network. The method may also include generating at least one network dependency between the root and a second node. The at least one generated network dependency corresponds to a connection between nodes of the network. The at least one generated network dependency corresponds to a directional path from the apparatus to the second node. The method may include polling the second node. The polling occurs via the at least one network dependency that has been generated between the apparatus and the second node. The method may also include determining that the second node is unreachable. The method may also include generating activated alerts relating to the unreachable second node, if any of the parent nodes of the second node are determined to be reachable by the apparatus.

Method and apparatus for generating network dependencies

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

A method of adaptive resource allocation in transmitting data is provided. In particular, the method of the present invention is applicable to scheduling bandwidths using a modified and dynamic weighted round robin process. The method includes the steps of allocating a resource to each of a plurality of data transmitting active connections, the plurality of active connections belonging to more than one class of service. Then the method determines a lender class of service for each active connection from which resources may be reallocated to the active connection, and periodically comparing the resource usage of an active connection to an upper threshold and a lower threshold. Borrowing action for resources from the lender class of service for the active connection is carried out in response to the current usage exceeding the upper threshold, and returning action for borrowed resources to the lender class of service from the active connection in response to the current usage being less than the lower threshold is carried out.

Method of active dynamic resource assignment in a telecommunications network

A method of optimizing access network utilization is provided. The access network includes a plurality of integrated access devices coupled to a segment and reassembly device, where each segment and reassembly device has a plurality of channels, X. The method includes the steps of providing a plurality of subscriber lines, &#x3a3;m, coupled to the integrated access devices, providing a plurality of integrated access device lines, &#x3a3;n, between the integrated access devices and the segment and reassembly device, multiplexing the plurality of subscriber lines by the integrated access device onto the plurality of integrated access device lines, such that &#x3a3;m&#x3e;&#x3a3;n=X, and providing a reorder tone to any subscriber whose call is blocked.
