Abstract: In a publish-subscribe environment like the Air Force Joint Battlespace Infosphere (JBI), information/data has to be efficiently and reliably transmitted between servers and clients. However, due to various reasons such as unexpected network traffic, hardware/software failure, etc., the overlay network of the system may require reconfiguration, leading to intolerable service interruption of information flow to time-critical applications. This paper proposes theoretical methods for providing temporary respite to the time-critical clients while the backbone network is under repair.

Keywords: overlay networks; Joint Battlespace Infosphere; US Air Force JBI; alternate server lists; recovery schemes; reliability; information flow; time-critical applications; service interruption; publish-subscribe environments.
