The following timers are associated with the client framework operations:

  • Upload Timer:

    Set by the higher-layer applications in the client at the beginning of each segment retrieval session. The segment retrieval session aborts when the Upload Timer expires.<10>

  • Server List Timer:

    A separate instance of this timer is started for each empty Server Information List that is created and for each previously populated Server Information List that becomes empty.

    It is disabled if the Server Information List becomes populated.

    An empty Server Information List is removed when its Server List Timer expires. The default timeout value is set to 15 seconds.<11>

    When the Server List Timer for a Server Information List of a segment expires, the list is deleted.

  • Server Entry Timer:

    The timer for each server entry in a Server Information List.

    It is started after an entry is added to the Server Information List. An entry is removed from the list after its timer expires. The default timeout value is set to 15 seconds.<12>

    When the Server Entry Timer for an entry in a segment ID's Server Information List expires, the entry is deleted from the cache.
