With the rapid development of electronic products, the high-speed computing and the personal mobile terminal all make greater demands the on-chip performance. Due to the limited bandwidth, the low communication efficiency and the bad scalability, the Network on Chip (NoC) has been unable to satisfy the requirements of the applications above. More recently, the Optical NoC (ONoC) is introduced as an...
A major challenge in data center networks is to provide enough network capacity to meet the ever increasing demand of large-scale distributed computing. While existing proposals focus on adding more switches and links, which cost extra hardware and energy, we explore another dimension in which spare disk space at servers is used for caching data, so as to increase network throughput without additional...
A Banyan-type network is a typical network topology for optical interconnection networks. In this paper, we propose a routing algorithm to generate the nonblocking connections for any request on a Banyan-type network with a given cross talk constraint, in which the number of planes exactly equals to the necessary and sufficient condition derived in our previous results. In addition, we analyze this...
With the development of Multi-Processor System-on-Chip (MP-SoC) in recent years, the intra-chip communication is becoming the bottleneck of the whole system. Current electronic network-on-chip (NoC) designs face serious challenges, such as bandwidth, latency and power consumption. Optical interconnection networks are a promising technology to overcome these problems. In this paper, we study the routing...
Multicast communications have become more and more important recently, especially in their applications in multimedia communication, quality of service (QoS), video conferencing, and distance education. In a point-to-point (PTP) optical communication system, how to provide multicast services is an essential issue. There are some advantages of active splitter/active combiner (AS/AC) networks, such...
In this paper, we study the waveband switching for wavelength-level demands and the traffic grooming for sub-wavelength-level demands in multi-granularity optical networks and propose a new routing algorithm called multi-granularity grooming based on Integrated Grooming Auxiliary Graph (MG-IGAG) to save the cost by reducing the number of switching ports in optical-cross connects. In MG-IGAG, we develop...
The Benes network is a long established method to connect large switching networks. This network has the characteristic of providing multiple paths for same output request. In this paper, we present a new routing algorithm that can route data from given input to the desired output. Our method uses one of the available paths for input/output request dynamically from each input to each output, and thus...
The ever increase in the Internet traffic resulted in an increase in the number of wavelengths per fibre in WDM networks. Consequently, the required number of optical ports increases which accordingly increases the cost of the optical cross connect and the complexity of the routing and wavelength assignment algorithms. As a result, the multi-granular switching concept was introduced to reduce the...
In this paper we discuss new energy efficient paradigms for optical networks. With the increasing number of high bandwidth applications, devices used in backbone networks such as optical networks increase. Energy consumption of optical networks is an important issue that has to be addressed. In this work we propose novel routing algorithms for decreasing the energy consumption of optical networks...
We demonstrate the impact of optical switch, amplifier and MUX/DEMUX characteristics on optical network performance evaluated from our physical-impairment-based RWA algorithm. We present blocking probabilities as a function of traffic load and network device parameters.
