The state
property in an RTCIceCandidatePairStats
object indicates the state of the check list of which the candidate pair is a member.
Syntax
state = rtcIceCandidatePairStats.state;
Value
A DOMString
whose value is one of those found in the RTCStatsIceCandidatePairState
enumerated type.
ICE check lists
During ICE negotiation, the ICE layer builds up a check list, which is a list of potential pairings of ICE candidates. Each pair has a state, whose value is represented by RTCStatsIceCandidatePairState
.
When a candidate pair is added to the check list, it begins in the frozen
state. As soon as there are no checks ongoing which block the pair from being analyzed, it is unfrozen and moves into the waiting
state. This may happen immediately upon being added to the check list.
Each time a candidate pair is done being checked, the next-highest priority candidate pair remaining on the check list moves from the waiting
state to the in-progress
state, and its check begins. If the check fails for any reason, the pair moves into its final state, failed
. If the check succeeds, the pair ends up in the succeeded
state.
The ICE check list state for any given pair of ICE candidates can be found in the corresponding the state
property.
