Enum DistributionStrategy 

pub enum DistributionStrategy {
    Broadcast,
    RoundRobin,
    Discovery {
        is_responsive: bool,
    },
    Tracemap,
}

How tasks should be distributed to workers

Variants

Broadcast

Broadcast tasks to all probing workers simultaneously (LACeS, and unicast-only latency)

RoundRobin

Send tasks to probing workers in round-robin fashion (catchment mode)

Discovery

Send discovery tasks round-robin, with follow-up task interleaving (latency, traceroute, responsive modes)

Fields

is_responsive: bool

–responsive sends follow-ups to ALL workers; otherwise to the catching worker

Tracemap

Seed binary-search trace sessions round-robin, with follow-up task interleaving (tracemap mode)

Implementations

impl DistributionStrategy

pub fn select(m_def: &ScheduleMeasurement) -> Self

Select the distribution strategy for a measurement definition.

• catchment → RoundRobin: one probe per target
• tracemap → Tracemap
• anycast-traceroute → Discovery: find the catching worker first
• latency with an anycast origin → Discovery: measure from the catching worker
• latency with only unicast origins → Broadcast: every worker measures from its own unicast address (no discovery needed)
• laces → Broadcast
• --responsive gates either broadcast probes or multi-target hitlist probing.

pub fn is_gated_broadcast(&self) -> bool

Whether follow-up probes are broadcast to all workers, rather than sent by the worker that caught the discovery probe.
