In this paper, we consider a special discrete-time queuing system with two head-of-line (HOL) priority queues and a mix of correlated and uncorrelated arrivals. The arrival process to the high priority queue is correlated and consists of a train of a fixed number of fixed-length packets, while the low priority traffic consists of batch arrivals that are independent and identically distributed f...

It is not an easy task to write a book on queuing networks when a large number of books in the topic have already been published. The authors have written a very timely book on queuing networks which can be used by people working in the area of communication networks. The basics of stochastic process have been discussed in Chapter 1 with queuing networks being introduced in Chapter 2 where the ...

Distributed transactional memory (TM) promises to alleviate difficulties with lock-based (distributed) synchronization and object performance bottlenecks in distributed systems. In distributed TM systems, both the management and consistency of a distributed transactional object are ensured by a cache-coherence protocol. In this paper, we formalize two classes of cache-coherence protocols: distr...

Service differentiation that provides prioritized service qualities to multiple classes of client requests can effectively utilize available server resources. This paper studies how demand-driven service differentiation with admission control can be supported in cluster-based network services. Our objective is to provide better services to high priority request classes without over-sacrificing ...

Service differentiation that provides prioritized service qualities to multiple classes of client requests can effectively utilize available server resources. This paper studies how demand-driven service differentiation in terms of end-user performance can be supported in cluster-based network servers. Our objective is to deliver better services to high priority request classes without over-sac...

In order to overcome the problem of flow collision of the integrative information transmission in the switched Ethernet for substation process-level (SESPL), this paper proposed a novel priority-based transfer scheme in the end-nodes based on the information model, in which different priorities are assigned according to different information types by using the user priority field defined in the...

A Maximum Expected Covering Problem for Locating and Dispatching Two Classes of Military Medical Evacuation Air Assets Report Title Military medical evacuation (MEDEVAC) systems respond to casualty incidents and transport the most urgent casualties to a medical treatment facility via multiple types of air ambulance assets. Military MEDEVAC systems are subject to an uncertain number of service c...
