@property (nonatomic, copy, readonly, nullable) NSString *localCandidateIp

Declared In

TVOIceCandidatePairStats.h

  remoteCandidateId

The unique identifier that is associated to the object that was inspected to produce the Ice candidate attributes for the remote candidate associated with this candidate pair.

@property (nonatomic, copy, readonly, nullable) NSString *remoteCandidateId

Declared In

TVOIceCandidatePairStats.h

  remoteCandidateIp

The IP address of the remote candidate associated with this candidate pair.

@property (nonatomic, copy, readonly, nullable) NSString *remoteCandidateIp

Declared In

TVOIceCandidatePairStats.h

  state

Represents the state of the checklist for the local and remote candidates in a pair.

@property (nonatomic, assign, readonly) TVOIceCandidatePairState state

Declared In

TVOIceCandidatePairStats.h

  priority

The priority of the candidate. Priority is calculated as defined in [RFC5245] section 15.1.

@property (nonatomic, assign, readonly) uint64_t priority

Declared In

TVOIceCandidatePairStats.h

  nominated

This booean is related to updating the nominated flag described in Section 7.1.3.2.4 of [ RFC5245].

@property (nonatomic, assign, readonly, getter=isNominated) BOOL nominated

Declared In

TVOIceCandidatePairStats.h

  writeable

Has gotten ACK to an ICE request.

@property (nonatomic, assign, readonly, getter=isWriteable) BOOL writeable

Declared In

TVOIceCandidatePairStats.h

  readable

Has gotten a valid incoming ICE request.

@property (nonatomic, assign, readonly, getter=isReadable) BOOL readable

Declared In

TVOIceCandidatePairStats.h

  bytesSent

Represents the total number of payload bytes sent on this candidate pair, i.e., not including headers or padding.

@property (nonatomic, assign, readonly) uint64_t bytesSent

Declared In

TVOIceCandidatePairStats.h

  bytesReceived

Represents the total number of payload bytes received on this candidate pair, i.e., not including headers or padding.

@property (nonatomic, assign, readonly) uint64_t bytesReceived

Declared In

TVOIceCandidatePairStats.h

  totalRoundTripTime

Total round trip time.

@property (nonatomic, assign, readonly) CFTimeInterval totalRoundTripTime

Discussion

Represents the sum of all round trip time measurements in seconds since the beginning of the session, based on both STUN connectivity check [ STUN-PATH-CHAR] responses (responsesReceived) and consent [ RFC7675] responses (consentResponsesReceived). The average round trip time can be computed from totalRoundTripTime by dividing it by (responsesReceived + consentResponsesReceived).

Declared In

TVOIceCandidatePairStats.h

  currentRoundTripTime

Current round trip time.

@property (nonatomic, assign, readonly) CFTimeInterval currentRoundTripTime

Discussion

Represents the latest round trip time measured in seconds, computed from both STUN connectivity checks [STUN-PATH-CHAR] and consent responses [RFC7675].

Declared In

TVOIceCandidatePairStats.h

  availableOutgoingBitrate

Available outgoing bitrate

@property (nonatomic, assign, readonly) double availableOutgoingBitrate

Discussion

It is calculated by the underlying congestion control by combining the available bitrate for all the outgoing RTP streams using this candidate pair. The bitrate measurement does not count the size of the IP or other transport layers like TCP or UDP. It is similar to the TIAS defined in [RFC3890], i.e., it is measured in bits per second and the bitrate is calculated over a 1 second window.

Declared In

TVOIceCandidatePairStats.h

  availableIncomingBitrate

Available incoming bitrate

@property (nonatomic, assign, readonly) double availableIncomingBitrate

Discussion

It is calculated by the underlying congestion control by combining the available bitrate for all the incoming RTP streams using this candidate pair. The bitrate measurement does not count the size of the IP or other transport layers like TCP or UDP. It is similar to the TIAS defined in [RFC3890], i.e., it is measured in bits per second and the bitrate is calculated over a 1 second window.
