Hello,<br><br>For exit router selection path-spec says that; <br><br>"For circuits that do not need to be "fast", when choosing among multiple candidates for a path element, we choose randomly. For "fast" circuits, we pick a given router as an exit with probability proportional to its bandwidth."<br>
<br>Could anybody explain why Tor pick exit router with probability proportional to its bandwidth <b>only for fast circuits</b>? As far as i know Tor uses this technique for load-balance. But why it uses this technique only for fast circuits?<br>
<br>Thanks in advance.<br><br><br><br>
