Struct PathFrame 

pub struct PathFrame {
    pub ttl: u8,
    pub ecn: u8,
    pub hop_count: u8,
    pub ce_count: u64,
    pub ect_count: u64,
}

The peer’s view of THIS endpoint’s packets: the TTL it saw, the ECN bits, and the hop count it derived from the TTL. A change in hop_count is a router-level path shift, often visible before throughput moves.

AccECN (item 15): ce_count / ect_count are the peer’s CUMULATIVE counts of our CE-marked and ECN-capable packets, so the sender derives a graded ce_rate = delta_CE / delta_ECT between frames instead of reading a single CE bit. An AQM marks CE before it tail-drops, so a rising rate leads loss.

Fields

ttl: u8

ecn: u8

hop_count: u8

ce_count: u64

ect_count: u64
