Enum MultipathStrategy 

pub enum MultipathStrategy {
    Classic,
    Paris,
    Dublin,
}

The Equal-cost Multi-Path routing strategy.

Variants

Classic

The src or dest port is used to store the sequence number.

This does not allow fixing both the src and dest port and so PortDirection::Both and SequenceField::Port are mutually exclusive.

Paris

The UDP checksum field is used to store the sequence number.

a.k.a. paris traceroute approach.

This requires that the UDP payload contains a well-chosen value to ensure the UDP checksum remains valid for the packet and therefore this cannot be used along with a custom payload pattern.

Dublin

The IP identifier field is used to store the sequence number.

a.k.a. dublin traceroute approach.

The allow either the src or dest or both ports to be fixed.

If either of the src or dest port may vary (i.e. PortDirection::FixedSrc or PortDirection::FixedDest) then the port number is set to be the initial_sequence plus the round number to ensure that there is a fixed flowid (protocol, src ip/port, dest ip/port) for all packets in a given tracing round. Each round may therefore discover different paths.

If both src and dest ports are fixed (i.e. PortDirection::FixedBoth) then every packet in every round will share the same flowid and thus only a single path will be discovered.

Trait Implementations

impl Clone for MultipathStrategy

fn clone(&self) -> MultipathStrategy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MultipathStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MultipathStrategy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MultipathStrategy

fn eq(&self, other: &MultipathStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
