in this study, a robust controller is designed for fuzzy network control systems (ncss) using the static output feedback. delay and data packet dropout affect on the stability of network control systems, and therefore, the asymptotic stability condition is established considering delay and data packet dropout. delay is time-varying while the lower and upper bounds for delay is defined, and the ...

The fundamental economics of packet networking has led us to a mechanism to guarantee quality of service (QoS) with no flow handling in the core Internet, giving far better scalability, robustness and simplicity than previously. The same packet congestion mechanism is then generalised to encourage customers to manage all classes of traffic responsibly and with optimal utilisation. A vision of t...

Buffer sizing in Internet routers is a fundamental problem that has major consequences in design, implementation, and the economy of the routers, as well as on the performance observed by the end users. Recently, there have been some seemingly contradictory results on buffer sizing. On one hand, Appenzeller et al. show that as a direct consequence of desynchronization of flows in the core of th...

At present, in the field of application of numerous IT, multi-core processors are widely used, the hardware development is much faster than the speed of software development. Multi-core processor software is using the design concept of single-core processor software, so this software is not highperformance and the performance processor is not fully played. This paper firstly introduces the trad...

In this paper, we present the Tiny Tera: a small packet switch with an aggregate bandwidth of 320Gb/s. The Tiny Tera is a CMOS-based input-queued, fixed-size packet switch suitable for a wide range of applications such as a highperformance ATM switch, the core of an Internet router or as a fast multiprocessor interconnect. Using off-the-shelf technology, we plan to demonstrate that a very highb...

Recently, several researchers have proposed adopting software-defined networking (SDN) concepts for mobile network architectures, particularly for LTE-evolved packet core (LTE/EPC). Although several new designs have been introduced for architectures based on SDN or its concrete realization, Openflow, few studies have presented in-depth discussions of real procedures that are relevant to such ar...

Compared to specialized network equipment, software routers running on commodity servers allow programmers to rapidly build and (re)program networks using the software and hardware platforms they tend to be most familiar with—that of the general-purpose computer. Unfortunately, the Achilles’ heel of software routers has been performance; commodity servers have traditionally proven incapable of ...

Nowadays commodity hardware is offering an ever increasing degree of parallelism (CPUs with more and more cores, NICs with parallel queues). However, most of the existing network monitoring software has not yet been designed with high parallelism in mind. Therefore we designed a novel packet capturing engine, named PFQ, that allows efficient capturing and in–kernel aggregation, as well as conne...
