A software architecture is proposed for hybrid packet/optical data centers employing programmable NETCONF-enabled optical switching matrix, and a performance evaluation is presented comparing hybrid and electrical-only architectures for elephant flows under different traffic patterns. Network throughput and jitter are evaluated on an emulation environment, and benefits for the hybrid scenario are...
Vehicular adhoc networks come out to be a promising solution for ensuring traffic and road safety on highways. However this area induces communication challenges such as topology dynamics, and connectivity losses. Today's Vanet demand a sound planning to make architectural level decisions. Integrating Vanet with emerging Software defined Networking brings ground-breaking networking innovation. Recent...
In this paper, we propose a novel architecture for next generation cellular networks that enables collaborative forwarding at Layer 2 among adjacent eNBs with the aid of enhanced user equipment (UE) devices, that act voluntarily as packet forwarders. Therefore, legacy UEs are leveraged as active network elements being capable of operating simultaneously over multiple base stations (eNBs). To this...
In Distributed Cloud Computing, applications are deployed over thousands of geographically distributed cloud sites. This new deployment approach promises not only improved application's quality of service but enables deploying network-critical applications otherwise not possible. A previously settled, static allocation of enough resources at each site is expensive. Adapting resource allocations during...
New Internet architectures have been proposed to address some of the shortcomings of the current Internet. Many new architectures represent existing and novel networking functionality as network "services". These services are fundamental building blocks that need to be described and can be composed in an effective manner. Any service-based network architecture fundamentally struggles to...
This article analyzes network management system based on C/S and B/S architecture. Incorporating with advantages of two types of architecture, a design idea is brought up for building a network management system based on J2EE and RIA technology. Major common functions for network management system are designed and realized through research and analysis of data transmission mechanism among each layer...
The performance of a software system has been a major concern of the information technology services industry since its inception in the early 1960's. Up to now, simulation has been a key technique for gaining an understanding of the performance characteristics of the system during development time, while software tools, possibly together with manual operations, have been used to monitor some performance...
Networks-on-chip (NoCs) have emerged as an alternative to ad-hoc wiring or bus-based global interconnection in Systems-on-Chip (SoCs). The architecture of network significantly determines system performance. This paper proposes a network on chip architecture with 2-demention mesh topology, odd-even routing algorithm, wormhole switching technique and only input buffers. The size of packet is 20 bytes...
Signal processing applications have high instruction level parallelism (ILP) and real-time performance requirements. Embedded and application specific multicluster architecture is desirable to provide the large computation power that these applications need. As technology moves to deep submicron level, it becomes more important and challenging to design an efficient intercluster connection network...
The feasibility of the residential area network architecture has been proposed, combined with personal video recorders (PVRs) and the fiber channel-arbitration loop (FC-AL) connection. However, the single-loop FC-AL-based architecture has the limitation on scalability. That is, the architecture only can allow 127 devices, thereby it cannot support the densely-populated apartments or buildings with...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
