developing reliable yet flexible software is a hard problem. although modeling methods enjoy a lot of advantages, the exclusive use of just one of them, in many cases, may not guarantee the development of reliable and flexible software. formal modeling methods ensure reliability because they use a rigorous approach to software development. however, lack of knowledge and high cost practically fo...

Frequently updated web objects reduce the benefit of caching, increase the problem of cache inconsistency, and aggravate the inefficiency of the conventional "repeated unicast" delivery model. In this paper, we investigate multicast invalidation and delivery of popular, frequently updated objects to web cache proxies. Our protocol, MMO, groups objects into volumes, each of which maps to one IP ...

Developers of communication software face many challenges. Communication software contains both inherent complexities, such as fault detection and recovery, and accidental complexities, such as the continuous re-rediscovery and re-invention of key concepts and components. Meeting these challenges requires a thorough understanding of object-oriented application frameworks and patterns. This pape...

Given the continued growth of the WorldWide Web, performance of Web servers is becoming increasingly important. File caching can be used to reduce the time that it takes a Web server to respond to client requests, by storing the most popular les in the main memory of the Web server, and by reducing the volume of data that must be transferred between secondary storage and the Web server. In this...
