Abstrak – DLNA berfungsi dan bertujuan untuk memudahkan para penggunanya untuk berbagi/sharing konten antara perangkat. Teknologi ini sebenarnya telah banyak digunakan orang-orang dimana begitu banyak konten-konten yang disimpan pada komputer pribadi apakah itu foto, trek musik, atau bahkan file film. Dengan DLNA, pengguna dapat secara berkesinambungan mengalirkan/berbagi semua itu keseluruh isi rumah di perangkat lain yang telah terhubung seperti TV, printer, komputer menggunakan protokol UpnP (Universal Plug and Play). Dalam penerapan teknologi DLNA pada jaringan membutuhkan DLNA Media Server, Client dan Data Storage yang menyimpan file untuk diputar dalam jaringan. Dalam penelitian ini, DLNA Media Server menggunakan wireless router TP-Link MR3420 yang sudah terinstall firmware OpenWRT dan penyimpanan menggunakan Hardisk External 320GB dengan multi sistem operasi sebagai DLNA Media Client. Setelah melakukan beberapa pengujian termasuk compatibility, performa dengan parameter kecepatan read dan write pada server, power usage, network usage and total costs. Biaya yang dikeluarkan sekitar IDR 600.000 dengan daya yang dibutuhkan 7.65 watts, dan DLNA media server ini compatible dengan semua media client, tapi performanya kurang baik apabila digunakan oleh semua client secara bersamaan dan terus menerus

Aiming at some problems in the fields of industry monitoring technology (IMT) such as bad dynamic ability and poor versatility, this paper brought forward a kind of intelligent Status monitoring and Fault diagnosis Network System (SFNS) based on UPnP-Universal Plug and Play. The model for fault diagnosis network system was established according to characteristics and requirements of IMT network, and system network architecture was designed and realized by UPnP. Using embedded system technology, real-time data collection node, monitoring center node and data storage server were designed, and that supplies powerful real-time data support for SFNS. Industry fields experiments proved that this system can realize self recognition, seamless linkage and other self adapting ability, and can break through the limitation of real IP address to achieve real-time remote monitoring on line.

As the WLCG continues to consolidate the data storage resources to reduce maintaining costs, more storage elements will be decommissioned or federated in the future. In both cases data streaming would become a common method for data accessing in many LHC Tier 2 and Tier 3 computing centres which makes it vital to optimise the network usage (i.e. latency reduction and bandwidth utilisation). Consequently, the data cache service sits closely to the computing resources becomes a desirable tool. In this paper we discuss how to setup a XCache server at an example WLCG Tier 2 site (Edinburgh) and use the ATLAS analysis queue as a testbed to study the data caching performance. The results could be used to guide the future development to make the caching server more effective.

Controller Area Network is an ideal serial bus design suitable for modern embedded system based networks. It finds its use in most of critical applications, where error detection and subsequent treatment on error is a critical issue. CRC (Cyclic Redundancy Check) block was developed on FPGA in order to meet the needs for simple, low power and low cost wireless communication. This paper gives a short overview of CRC block in the Digital transmitter based on the CAN 2.0 protocols. CRC is the most preferred method of encoding because it provides very efficient protection against commonly occurring burst errors, and is easily implemented. This technique is also sometimes applied to data storage devices, such as a disk drive. In this paper a technique to model the error detection circuitry of CAN 2.0 protocols on reconfigurable platform have been discussed? The software simulation results are presented in the form of timing diagram.FPGA implementation results shows that the circuitry requires very small amount of digital hardware. The Purpose of the research is to diversify the design methods by using VHDL code entry through Modelsim 5.5e simulator and Xilinx ISE8.3i.The VHDL code is used to characterize the CRC block behavior which is then simulated, synthesized and successfully implemented on Sparten3 FPGA .Here, Simulation and Synthesized results are also presented to verify the functionality of the CRC -16 Block. The data rate of CRC block is 250 kbps .Estimated power consumption and maximum operating frequency of the circuitry is also provided.

Structured Cabling is not a demonstrative course, but a course to stimulate students’ learning interest and to improve experiment’s efficiency. Unfortunately there are some disadvantages for experimental instruments on the present market, such as low testing speed, low automation level and less functions, etc. A multi-processor structure is proposed in this paper, which consists of a 32-bit ARM processor S3C2440 and a 8-bit Single Chip Microcomputer STC89LE54. This structure is used to develop a new network cabling experimental instrument, which is based on embedded system. The instrument can achieve precise processing, such as synchronous data acquisition for wire cores of 32 standard network lines according to EIA/TIA568A Standard or EIA/TIA568B Standard, display and data storage, etc. The instrument has characteristics of high efficiency, fast response, automatic identification, and ease of use. It is used to implement consistency between teaching and job training. Therefore it has high practical value.
