Fields
topics: HashMap<TopicHash, TopicScoreParams, RandomState>
Score parameters per topic.
topic_score_cap: f64
Aggregate topic score cap; this limits the total contribution of topics towards a positive score. It must be positive (or 0 for no cap).
app_specific_weight: f64
P5: Application-specific peer scoring
ip_colocation_factor_weight: f64
P6: IP-colocation factor.
The parameter has an associated counter which counts the number of peers with the same IP.
If the number of peers in the same IP exceeds ip_colocation_factor_threshold, then the value is the square of the difference, ie
(peers_in_same_ip - ip_colocation_threshold)^2`.
If the number of peers in the same IP is less than the threshold, then the value is 0.
The weight of the parameter MUST be negative, unless you want to disable for testing.
Note: In order to simulate many IPs in a manageable manner when testing, you can set the weight to 0
thus disabling the IP colocation penalty.
ip_colocation_factor_threshold: f64
ip_colocation_factor_whitelist: HashSet<IpAddr, RandomState>
behaviour_penalty_weight: f64
P7: behavioural pattern penalties. This parameter has an associated counter which tracks misbehaviour as detected by the router. The router currently applies penalties for the following behaviors:
- attempting to re-graft before the prune backoff time has elapsed.
- not following up in IWANT requests for messages advertised with IHAVE.
The value of the parameter is the square of the counter over the threshold, which decays with BehaviourPenaltyDecay. The weight of the parameter MUST be negative (or zero to disable).
behaviour_penalty_threshold: f64
behaviour_penalty_decay: f64
decay_interval: Duration
The decay interval for parameter counters.
decay_to_zero: f64
Counter value below which it is considered 0.
retain_score: Duration
Time to remember counters for a disconnected peer.
