Determining Quality Information for a Route

摘要

Methods and systems for determining traffic information for devices along one or more routes are described. A content server may send a message to a plurality of devices along a route. The message may comprise an indication requesting each of the devices to send, to the content server, status information regarding the respective device. Intermediary devices may receive the message, respond with the requested information, and forward the message through the route. The message may comprise a stateless messaging protocol message such as an ICMP or UDP packet.
