Struct holochain::prelude::kitsune_p2p::dependencies::kitsune_p2p_types::dht::spacetime::GossipParams

pub struct GossipParams {
    pub max_time_offset: TimeQuantum,
    pub max_space_power_offset: u8,
}

Node-specific parameters for gossip. While the Topology must be the same for every node in a network, each node is free to choose its own GossipParams.

Choosing smaller values for these offsets can lead to less resource usage, at the expense of reducing opportunities to gossip with other nodes. This is also largely dependent on the characteristcs of the network, since if almost all nodes are operating with the same current timestamp and Arq power level, there will be very little need for reconciliation.

In networks where nodes are offline for long periods of time, or latency is very high (e.g. sneakernet), it could be helpful to increase these values.

Fields

max_time_offset: TimeQuantum

What +/- coordinate offset will you accept for timestamps? e.g. if the time quantum is 5 min, a time buffer of 2 will allow +/- 10 min discrepancies with gossip partners.

max_space_power_offset: u8

What difference in power will you accept for other agents’ Arqs? e.g. if the power I use in my arq is 14, and this offset is 2, I won’t talk to anyone whose arq is expressed with a power lower than 12 or greater than 16
