|

* As tokens are limited, DialRequests should be given a prioritized list of Multiaddrs to minimize the potential request time.
|
||||
* Once a single Multiaddr Dial has succeeded, all pending dials in that Dial Request should be aborted. All tokens should be immediately released to the Dialer.
|
||||
* If all Multiaddr Dials fail, or the DIAL_TIMEOUT max is reached for the entire DialRequest, all in progress dials for that DialRequest should be aborted. All tokens should immediately be released to the Dialer.
|
||||
* If a Multiaddr Dial fails and there are no more dials to use its token, that token should be immediately released to the Dialer.
