I came across this recent announcement [1] of a proposed protocol that promises "faster Web services" - it's called "Order-based Deadlock Prevention Protocol with Parallel Requests", developed by Jonghun Park, a professor at Pennsylvania State University's School of Information Sciences and Technology, It appears to address the Web services parallel of the classic "deadly embrace" OS scenario. Although the paper proposing this concept (to be titled "A Scalable Protocol for Deadlock and Livelock Free Co-Allocation of Resources in Internet Computing,") has yet been released, the article states: - This protocol "is based on an algorithm that lets it use parallel instead of serial methods to process requests. Such a method boosts the efficiency of how resources are shared over the Internet. " - Two problems "likely to become even bigger hindrances as Web services and Internet collaborative computing become widespread are livelock and deadlock. Livelock occurs when two or more processes keep shifting their requests in response to the changes occurring in the other--with neither process succeeding in carrying out any productive work. Deadlock occurs when two or more processes get bogged down waiting for the other to make a move. In other words, instead of concurrent applications collaborating, they will vie for resources or just freeze while waiting for the other to take a lead." - Park's research was presented last week at the Institute of Electrical and Electronics Engineers' Symposium on Applications and the Internet in Orlando, Fla. I would be very interested in learning of any thoughts or impressions on this concept.
