  2. Problems • Pre-allocating candidates can speed up setup times • However, it’s impossible to know how many candidates are needed until you have all streams and maybe an offer • The specification defines one thing, implementations do another

  3. Resolution • “candidatePoolSize” setting/constraint • Can be set in constructor or updateIce() • Non negative integer value, default zero • Causes the browser to allocate candidates • “icecandidate” events are generated as normal • Effective prior to setLocalDescription • After setLocalDescriptionis called, candidatePoolSize is ignored • Actual number of candidates is determined by the local description

  4. Remaining Items • What to do about ICE state? • Proposal: icestate can be “starting” state during this time • !: the spec described a “new” state in Section 4.3.1, which is not described in the enumeration • Editors to add to spec • Change step 1 for the RTCPeerConnection constructor • Add to the description for updateIce • Add definition of the constraint
