A computing system is configured to receive incoming packets at a first
priority designated for use when receiving packets that are not
associated with specific subscription levels. Incoming packets are
examined to determine whether they are associated with a particular
subscription level. Responsive to a determination that a given packet
received over a particular connection is associated with a particular
subscription level, the computing system is reconfigured to process
packets subsequently received over the same connection at a different
priority associated with the particular subscription level.
