Some embodiments are directed to a method performed by a pipe control node for managing network resources that are used to transport network traffic. The method includes allocating network resources to a virtual pipe for transporting a plurality of multimedia streams through the network. Utilization of the network resources by the plurality of multimedia streams transported through the virtual pipe is monitored relative to the network resources allocated to the virtual pipe. The network resources that are used by the plurality of multimedia streams transported through the virtual pipe are managed in response to the monitored utilization. Some other embodiments are directed to a corresponding pipe control node that manages network resources which are used to transport network traffic.
