Enum Class NetworkQualityLevel

All Implemented Interfaces:
Serializable, Comparable<NetworkQualityLevel>, Constable

public enum NetworkQualityLevel extends Enum<NetworkQualityLevel>
Twilio's Video SDKs, where possible, attempt to calculate a singular Network Quality Level describing the quality of a Participant's connection to a Room. This value ranges from unknown to 5, with unknown representing that the Network Quality Level can not be determined, 0 representing a failed network connection, 1 representing a poor network connection, and 5 representing an excellent network connection. The SDK calculates this metric only when connected to Group Rooms. In case of a connection to Peer-to-Peer Room the value is expected to be unknown at all times.

Note that the Network Quality Level is not an absolute metric but a score relative to the demand being placed on the network. For example, the NQ score might be a 5 while on a good network and publishing only an AudioTrack. Later, if a HD VideoTrack is added, the score might come down to 2. This also means that when the network is not being used at all (i.e. the Client is neither publishing nor subscribing to any tracks) the Network Quality Level will always be 5 given that any network will be capable of complying with a zero communications demand.

  • Enum Constant Details


      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_UNKNOWN
      The Network Quality Level cannot be determined or the Network Quality API has not been enabled.

      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_ZERO
      The network connection has failed

      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_ONE
      The Network Quality is Very Bad.

      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_TWO
      The Network Quality is Bad.

      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_THREE
      The Network Quality is Good.

      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_FOUR
      The Network Quality is Very Good.

      public static final NetworkQualityLevel NETWORK_QUALITY_LEVEL_FIVE
      The Network Quality is Excellent.
  • Method Details

    • values

      public static NetworkQualityLevel[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      an array containing the constants of this enum class, in the order they are declared
    • valueOf

      public static NetworkQualityLevel valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      name - the name of the enum constant to be returned.
      the enum constant with the specified name
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
