This paper concerns itself with the performance of deflection routing in optical burst-switched networks based on Just-Enough-Time (JET) signaling. Generally speaking, buffer requirement is not vital for JET-based optical burst switching (OBS). However, if deflection routing is enabled, optical buffers are necessary to solve the insufficient offset time(More)
Future broadband networks must support integrated services and offer flexible bandwidth usage. In our previous work in [1], we explored the optical link control (OLC) layer on the top of optical layer that enables the possibility of bandwidth on-demand (BoD) service directly over wavelength division multiplexed (WDM) networks. Today, more and more(More)
Generally speaking, buffer requirement is not vital for JET-based optical burst switching (OBS). However, if deflection routing is enabled, optical buffers are necessary to solve the insufficient offset time problem. Another solution, which can alleviate buffering, is to lengthen offset time in the beginning. As previous work indicated, a burst with extra(More)
In part because of the limitations of the TCP/IPprotocols used by the current Internet, the Future Internet has become an attractive network research topic. Recently, several projects focused on the Future Internet have been launched around the globe based on the Open Flow platform, such as those that are part of the GENI project in the U.S., the OFELIA(More)
Currently, support for digital media is one of the fastest growing requirements of the Internet as demand transitions from services designed to support primarily text and images to those intended also to support rich, high quality streaming multi-media. In response to the need to address this important 21st century communications challenge, an international(More)
Recently, Cloud Computing is getting considerable attentions not only as the technology trend but also the new business model. Virtualization plays an extremely important role in Cloud Computing. Server virtualization has been achieved using virtualization hypervisor software such as VMware, Xen, and KVM,etc. Virtual Machines (VMs) created by hypervisors(More)
Large scale data intensive science requires global collaboration and sophisticated high capacity data management. Traditionally, mismatches between the requirements of large scale science and the restrictions of generally deployed networks have been problematic. However, the emergence of more flexible networking, for example, using techniques based on(More)
Recently, the Future Internet technology becomes a popular research topic. To solve the problems caused in traditional network, most researchers propose various new network architectures. One of the famous architectures is Software-defined network (SDN), which can help users develop their own strategies freely without the limited functions on physical(More)
