Module path_selection 

RTT-based path selection with hysteresis RTT-based path selection with hysteresis

Path selection algorithm:

• Lower RTT paths preferred
• 5ms hysteresis to prevent flapping
• 3ms advantage for IPv6
• Direct paths strongly preferred over relay

Structs

PathCandidate

A candidate path with measured RTT

PathInfo

Information about a tracked path

PathManager

Manager for tracking and closing redundant paths

Enums

PathType

Type of path connection

Constants

IPV6_RTT_ADVANTAGE

RTT advantage given to IPv6 paths

MAX_CANDIDATES_PER_PEER

Maximum number of candidates per peer

MAX_INACTIVE_CANDIDATES

Maximum number of inactive candidates to keep

MIN_DIRECT_PATHS

Minimum number of direct paths to keep open

RTT_SWITCHING_MIN

Minimum RTT improvement required to switch paths (prevents flapping)

Functions

select_best_path

Select the best path from candidates

select_v4_v6

Compare IPv4 and IPv6 paths, applying IPv6 advantage
