Mobility in modern distributed systems is a vital feature though it brings up such problems as unforeseeable disconnections while crossing the boundaries of wireless cells or networks. Due to the limited coverage and the lack of co-operation between different networks, seamless switching between different networks becomes extremely difficult. This paper addresses the problem of accidental or in...

In this paper we propose the use of a TCP/IP-friendly link level error recovery mechanism with novel design in conjunction with state-of-the-art Transmission Control Protocol (TCP) enhancements to improve TCP performance on network paths involving Wireless Wide-Area Network (W-WAN) links. We show that by combining a selected set of TCP enhancements TCP performance is significantly improved over...

Traditional networked file systems like NFS do not extend to wide-area due to network latency and dynamics introduced in the WAN environment. In this paper we proposed the design of a wide-area networked system called WireFS. WireFS is based on NFS and extends to the WAN environment by introducing a file redirector infrastructure residing between the central file server and clients. The file re...

It has recently become apparant that very high speed wide area networks (WANs) are pushing the limits of existing protocols, such as the transmission control protocol (TCP). This has led to many proposed replacements for TCP [1], [2], [3], [4], [5], [6], [7], [8], which must be evaluated, optimized and eventually developed into the next generation of TCP. Although initial design and testing can...

Recent development of distributed cloud environments requires advanced network infrastructure in order to facilitate network automation, virtualization, high performance data transfer, and secured access of end-to-end resources across regional boundaries. In order to meet these innovative cloud networking requirements, software-defined wide area network (SD-WAN) is primarily demanded to converg...

Bulk data transfer in wide area networks (WAN) requires scalable and high network bandwidth. In this paper, we identify a number of the scalability limitations that affect the full utilization of peak theoretical network bandwidth. In addition, we study and classify different offered approaches to overcome some of the identified limitations and increase network bandwidth among Grid components i...

As an important transportation infrastructure, air traffic plays a more and more important role in regional development, and related research is gradually increasing. These studies have mainly focused on transport policy, aviation system organization, and so on (Fleming and Hayuth, 1994; Shaw and Ivy, 1994;Taffe, 1996; Hooper, 1997; O’Kelly, 1998; Graham and Guyer, 1999; Vowles, 2000; Burghouwt...
