 // This class is used to manage one service's rate protection. It maintains
 // a queue of connection successes and failures and analyzes the requests
 // over some period of time, in order to deduce the backoff time of every
 // request.
 // The backoff algorithm consists of two parts. Firstly, avoid too many
 // send events in a sliding window. That will prevent traffic overload.
