Supporting Time-Critical Clients in Scalable Pub-Sub Systems

Danyang Zhang, Mar. 13, 2008

In a pub/sub (publish/subscribe) environment like JBI (Joint Battlespace Infosphere), 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 needs to be reconfigured, thus intolerable service interruption may occur to time critical applications. This research proposed theoretical methods for providing temporary respite to the time-critical clients while the backbone network is under repair.
