Detailed Description

Accumulates per-packet statistics for an IAX2 stream delivered via the tap interface.

Member Data Documentation

◆ bandwidth

double _tap_iax2_stat_t::bandwidth

Current estimated stream bandwidth in bytes per second.

◆ bw_history

iax2_bw_history_item _tap_iax2_stat_t::bw_history[300]

Rolling circular buffer of recent bandwidth history samples.

◆ bw_index

uint16_t _tap_iax2_stat_t::bw_index

Index into bw_history at which the next sample will be written.

◆ bw_start_index

uint16_t _tap_iax2_stat_t::bw_start_index

Index into bw_history marking the start of the valid history window.

◆ cycles

int _tap_iax2_stat_t::cycles

Sequence number cycle counter (currently unused).

◆ delta

double _tap_iax2_stat_t::delta

Arrival time delta from the previous packet in seconds.

◆ delta_timestamp

uint32_t _tap_iax2_stat_t::delta_timestamp

Difference in IAX2 timestamp from the previous packet in milliseconds.

◆ diff

double _tap_iax2_stat_t::diff

Difference between expected and actual arrival time in seconds.

◆ first_packet

bool _tap_iax2_stat_t::first_packet

True if this is the first packet seen; do not use after iax2_packet_analyse() — check (flags & STAT_FLAG_FIRST) instead.

◆ flags

uint32_t _tap_iax2_stat_t::flags

Bitmask of STAT_FLAG_* values describing the state of this packet.

◆ jitter

double _tap_iax2_stat_t::jitter

Instantaneous jitter estimate for this packet in seconds.

◆ max_delta

double _tap_iax2_stat_t::max_delta

Maximum inter-arrival delta observed over the lifetime of this stream in seconds.

◆ max_jitter

double _tap_iax2_stat_t::max_jitter

Maximum instantaneous jitter observed over the lifetime of this stream in seconds.

◆ max_nr

uint32_t _tap_iax2_stat_t::max_nr

Frame number of the packet at which the maximum delta was observed.

◆ mean_jitter

double _tap_iax2_stat_t::mean_jitter

Running mean jitter over the lifetime of this stream in seconds.

◆ pt

uint16_t _tap_iax2_stat_t::pt

Payload type of the most recent packet.

◆ reg_pt

int _tap_iax2_stat_t::reg_pt

Registered payload type for this stream.

◆ seq_num

uint16_t _tap_iax2_stat_t::seq_num

RTP-compatible sequence number of this IAX2 packet.

◆ sequence

uint32_t _tap_iax2_stat_t::sequence

Running sequence counter used for internal ordering.

◆ start_seq_nr

uint16_t _tap_iax2_stat_t::start_seq_nr

Sequence number of the first packet in this stream.

◆ start_time

double _tap_iax2_stat_t::start_time

Absolute arrival time of the first packet in this stream in seconds.

◆ stop_seq_nr

uint16_t _tap_iax2_stat_t::stop_seq_nr

Sequence number of the most recent packet in this stream.

◆ time

double _tap_iax2_stat_t::time

Absolute arrival time of this packet in seconds.

◆ timestamp

uint32_t _tap_iax2_stat_t::timestamp

IAX2 timestamp of this packet in milliseconds.

◆ total_bytes

uint32_t _tap_iax2_stat_t::total_bytes

Cumulative total bytes received for this stream.

◆ total_nr

uint32_t _tap_iax2_stat_t::total_nr

Total number of packets received for this stream.

◆ under

bool _tap_iax2_stat_t::under

Underflow flag (currently unused).
