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.

Media flow tracing in third party devices

Techniques are presented herein for enabling performance monitoring of flows within a management and provisioning tunnel used for communicating packets between a wireless controller and wireless access point devices. A wireless controller that is configured to communicate with at least one wireless access point obtains a packet to be sent to the wireless access point for wireless transmission in a wireless network by the wireless access point. The wireless controller identifies, based on the packet, traffic session flow information associated with the packet. The wireless controller encapsulates the packet with a tunneling header that comprises the traffic session flow information and sends the encapsulated packet to the wireless access point. The tunneling header may also comprise an application identifier (ID) associated with the packet.

Wireless network flow monitoring

A management scheme compares a source address included in a received solicitation with an address for a registered endpoint. A communication including a management prefix is communicated to the endpoint when the source address matches the registered address.
