Abstract: In one implementation, data is communicated along a communications route in a network. A mediatrace request is generated for the communications route. Responses to the mediatrace request are received from along the communications route. The hop-by-hop latency is passively measured, from the responses, with one-way delay along the communications route in the network.

Abstract: A method is disclosed for transmitting system management requests to computer systems along a network path using a network control protocol, such as RSVP. For example, an originating node may send a single system management request along a path to a destination node using a network control protocol. Each computer system along the network path may analyze the network control protocol message to determine whether the message contains a system management request. If a system management request is found in the message, the computer system may perform the system management function identified in the request, and respond to it.

Abstract: In one implementation, performance statistics for a provider network are compiled and delivered outside of the provider network. The provider network includes a media trace proxy server that receives a media trace query for a media stream of a customer edge network device. The media trace proxy server initiates a route discovery process on the provider network in response to the request or in response to at least one network device in the provider network being nonresponsive to similar types of media trace queries. The media trace proxy server collects performance statistics from the at least one network device and forwards the performance statistics of the at least one network device to the customer edge network device. The performance statistics may include only those statistics authorized by a subscription level or administrative region of the customer edge network device.
