TL;DR: This paper proposes an improved Wake-on-LAN device that incorporates the usage of basic Wake- on-LAN technology into a network management and power saving product.
Abstract: In distributed systems a computer generally process information of distributed application or provide service in distributed system. Therefore, computers connected in distributed system need to keep on all time. It leads to the concept of Wake-on-LAN (Local Area Network). However, keeping on during the idle period is the wastage of power. Therefore, it is essential to save the power while being efficient in network management. In this paper we propose an improved Wake-on-LAN device that incorporates the usage of basic Wake-on-LAN technology into a network management and power saving product.

TL;DR: The overall design and implementation of Netbed is presented and its ability to improve experimental automation and efficiency is demonstrated, leading to new methods of experimentation, including automated parameter-space studies within emulation and straightforward comparisons of simulated, emulated, and wide-area scenarios.
Abstract: Three experimental environments traditionally support network and distributed systems research: network emulators, network simulators, and live networks. The continued use of multiple approaches highlights both the value and inadequacy of each. Netbed, a descendant of Emulab, provides an experimentation facility that integrates these approaches, allowing researchers to configure and access networks composed of emulated, simulated, and wide-area nodes and links. Netbed's primary goals are ease of use, control, and realism, achieved through consistent use of virtualization and abstraction.By providing operating system-like services, such as resource allocation and scheduling, and by virtualizing heterogeneous resources, Netbed acts as a virtual machine for network experimentation. This paper presents Netbed's overall design and implementation and demonstrates its ability to improve experimental automation and efficiency. These, in turn, lead to new methods of experimentation, including automated parameter-space studies within emulation and straightforward comparisons of simulated, emulated, and wide-area scenarios.

TL;DR: An approach is presented for minimizing power consumption for digital systems implemented in CMOS which involves optimization at all levels of the design and has been applied to the design of a chipset for a portable multimedia terminal that supports pen input, speech I/O and full-motion video.
Abstract: An approach is presented for minimizing power consumption for digital systems implemented in CMOS which involves optimization at all levels of the design. This optimization includes the technology used to implement the digital circuits, the circuit style and topology, the architecture for implementing the circuits and at the highest level the algorithms that are being implemented. The most important technology consideration is the threshold voltage and its control which allows the reduction of supply voltage without significant impact on logic speed. Even further supply reductions can be made by the use of an architecture-based voltage scaling strategy, which uses parallelism and pipelining, to tradeoff silicon area and power reduction. Since energy is only consumed when capacitance is being switched power can be reduced by minimizing this capacitance through operation reduction choice of number representation, exploitation of signal correlations, resynchronization to minimize glitching, logic design, circuit design, and physical design. The low-power techniques that are presented have been applied to the design of a chipset for a portable multimedia terminal that supports pen input, speech I/O and full-motion video. The entire chipset that performs protocol conversion, synchronization, error correction, packetization, buffering, video decompression and D/A conversion operates from a 1.1 V supply and consumes less than 5 mW. >

TL;DR: In this paper, a link layer gateway computer (H4) coupled to both the first and second network medium and the second medium is used to communicate a data packet from a source host computer selected from one of the plurality of host computers coupled to the first network medium.
Abstract: A network configuration including a first network medium
which is a 1394 network as well as a second network medium.
Each of the first and second network media is coupled to a
corresponding plurality of host computers (H1 through H3 and
H5 through H7). The network configuration further includes a
link layer gateway computer (H4) coupled to both the first
network medium and the second network medium. The link layer
gateway computer is operable to communicate a data packet from
a source host computer selected from one of the plurality of
host computers coupled to the first network medium to a
destination host computer selected from one of the plurality
of host computers coupled to the second network medium.
Additionally, the link layer gateway computer is operable to
communicate a data packet from a source host computer selected
from one of the plurality of host computers coupled to the
second network medium to a destination host computer selected
from one of the plurality of host computers coupled to the
first network medium.

TL;DR: It is argued that a live wireless and mobile experimental facility focusing on ease of use and accessibility will not only greatly lower the barrier to research in these areas, but that the primary technical challenges can be overcome.
Abstract: The success of ns highlights the importance of an infrastructure that enables efficient experimentation. Similarly, Netbed's automatic configuration and control of emulated and live network environments minimizes the effort spent configuring and running experiments. Learning from the evolution of these systems, in this paper we argue that a live wireless and mobile experimental facility focusing on ease of use and accessibility will not only greatly lower the barrier to research in these areas, but that the primary technical challenges can be overcome.The flexibility of Netbed's common abstractions for diverse node and link types has enabled its development from strictly an emulation platform to one that integrates simulation and live network experimentation. It can be further extended to incorporate wireless and mobile devices. To reduce the tedium of wireless and mobile experimentation, we propose automatically allocating and mapping a subset of a dense mesh of devices to match a specified network topology. To achieve low-overhead, coarse repeatability for mobile experiments, we outline how to leverage the predictability of passive couriers, such as PDA-equipped students and PC-equipped busses.
