Outbound Queue Size

Provides an example on how to calculate the outbound queue size.

The size of an outbound queue is calculated using:
OutboundQueueSize = OutboundQueueVolume * (FailureDuration + SaveInterval)
where:
  • OutboundQueueVolume is the amount of data in bytes entering the queue per time period.

  • FailureDuration is the maximum time the queue is expected to buffer data for an unavailable site. For the purpose of these example calculations, assume that failure duration is set at 4 hours (14,400 seconds).

  • SaveInterval is the time configured for that particular queue. For the purpose of these calculations, assume that the save interval is 2 hours (7200 seconds).

  • FailureDuration + SaveInterval is 21,600 seconds.

The OutboundQueueSizes for the three sites are:
Site1 = 7K/sec * 21,600sec = 151MB
Site2 = 15K/sec * 21,600sec = 324MB
Site3 = 9K/sec * 21,600sec = 194MB
