This paper analyzes some approaches to manage the network topology of EJB clustering, and presents a Network Topology Management System that based on shared global JNDI, including overall design for this system and detailed design for some key technologies. The Management of network topology is a submodule of cluster service, and it makes the cluster system have two important features: flexible scalability...
The distributed hash tables (DHTs) exhibit several interesting properties, such as self-configuration, self-maintenance, scalability and robustness that are clearly desirable for many kinds of applications in the Internet. However, Most of DHT approaches have high resolution latency because each lookup need contact several servers in sequence, typically O(log n) hops (n is the number of peers in the...
Intensive and extensive development of computer networks generates the problem of providing a suitably high level of network survivability. A lot of research has been done in this area in recent years, including studies associated with the use of a modern tool called p-cycles. p-Cycles not only provide a high level of protection, but also achieve it at a quite low cost. Until now, p-cycles have been...
In distributed virtual environments, e.g., online gaming, collaborative designs and distributed military simulations, interactivity is one of the most important requirements. The users may notice serious degradations in quality of service when interacting in the virtual world if the response from the system is much slower than what they have experienced in real life. In this paper, we consider the...
