The invention includes a method and apparatus for determining the performance of a virtual concatenation group (VCG) signal transporting a client signal over a transport network. A method includes collecting a plurality of performance monitoring indicators associated with a plurality of VCG member signals of the VCG signal, synchronizing the performance monitoring indicators with respect to each other, combining the synchronized performance monitoring indicators to form VCG-level performance monitoring indicators, calculating VCG-level performance monitoring primitive measurements based on the VCG-level performance monitoring indicators, and processing the VCG-level performance monitoring primitive measurements to determine VCG performance.

Method and apparatus for monitoring virtual concatenation group performance

A system for transporting downstream and upstream traffic between service providers and end user terminals is provided. The system may include an apparatus having multiple egress ports configured for transmitting downstream traffic received from the service providers towards nodes adapted for replicating the traffic, at one network layer, and further transmitting the replicated traffic toward the end user terminals. The system may further include a merging unit coupled to ingress port of another apparatus receiving upstream traffic from the user end terminals, where the merging unit is adapted for merging the upstream traffic, at a different network layer, according to which service provider the upstream traffic received from the end user terminals is intended to and for transmitting the merged traffic toward the service providers.

Apparatus for providing internet protocol television service and internet service

The invention includes an apparatus and associated method for monitoring signals. The apparatus includes a port unit including a plurality of monitoring functions associated with a respective plurality of data communication channels, and a switch unit adapted for switching signals conveyed by the data communication channels, where the switch unit includes a monitoring function controller and a plurality of monitoring function images associated with the respective monitoring functions. The monitoring function images are adapted for conveying configuration information from the monitoring function controller to the respective monitoring functions and conveying status information from the respective monitoring functions to the monitoring function controller.

Method and apparatus for improved non-intrusive monitoring functions

The invention comprises a method and apparatus for assigning at least one virtual concatenation group member to a virtual concatenation group at a terminating node. Specifically, the method comprises receiving originating configuration information comprising at least one assignment parameter and at least one originating capability parameter, identifying terminating configuration information associated with the terminating node where the terminating configuration information comprises at least one terminating capability parameter, comparing the at least one originating capability parameter to the at least one terminating capability parameter, and assigning the at least one virtual concatenation group member to the virtual concatenation group on the terminating node using the at least one assignment parameter in response to a determination that the at least one originating capability parameter and the at least one terminating capability parameter are compatible.
