Parameters

All nodes in a Substrate Mix Network should agree on the following parameters:

• Mean forwarding delay. This is the average artificial packet delay at each hop.
• Mean extrinsic delay. This is the average artificial delay between receipt of a SubmitExtrinsic request and import of the attached extrinsic.
• Maximum fragments per message. See the message fragmentation chapter.
• Maximum length of a mixnode's request/reply queue. Note that in sessions where a node is not a mixnode, it is free to choose the queue bound itself.
• Reply cooldown. If a node receives two requests with the same message ID within this time period, it should not reply to both of them. See the requests and replies chapter.
• Average cover traffic rates. There are four independent rates: mixnode loop, mixnode drop, non-mixnode loop, and non-mixnode drop. See the cover traffic chapter.
