Interoperability and Reliability of Multiplatform MPLS VPN: Comparison of Traffic Engineering with RSVP-TE Protocol and LDP Protocol

One of the alternatives to overcome network scalability problem and maintaining reliability is using MPLS VPN network. In reallity, the current network is already using a multiplatform of several different hardware vendors, i.e., Cisco and Juniper platforms. This paper discusses the comparison of the simulation results to see interoperability of multiplatform MPLS VPN andreliability through traffic engineering using RSVP-TE and LDP protocols. Both the RSVP and LDP protocols are tested on a stable network and in a recovery mode,as well as non-load conditions and with additional traffic load. The recovery mode is the condition after the failover due to termination of one of the links in the network. The no-load condition means that the network is not filled with additional traffic. There is only traffic from the measurement activity itself. While network conditions with an additional load are conditions where there is an additional UDP packet traffic load of 4.5 Mbps in addition to the measurement load itself. On a stable network and without additional traffic load, the average delay on LDP protocol is 59.41 ms, 2.06 ms jitter, 0.08% packetloss, and 8.99 Mbps throughput. Meanwhile, on RSVP protocol, the average delay is 52.40 ms, 2.39 ms jitter, 12.18% packet loss, and 7.80 Mbps throughput. When failover occurs and on recovery mode, LDP protocol is48% of packet loss per 100 sent packets while on RSVP packet loss percentage is 35.5% per 100 sent packets. Both protocols have interoperability on the third layer of multiplatform MPLS VPN, but on heavy loaded traffic condition, RSVP protocol has better reliability than the LDP protocol

Xbee berfungsi sebagai alat komunikasi nirkabel yang beroperasi pada frekuensi 2,4 Ghz dengan jarak jangkau mencapai 1.500 meter. Pada perancangan ini terdapat dua node, yaitu node pengirim dan node penerima. Node pengirim terdiri dari modul Arduino sebagai pengendali yang dihubungkan dengan sensor DHT11 sebagai masukan dan Xbee sebagai pengirim. Node penerima terdiri dari Xbee penerima yang dihubungkan pada modul Arduino sebagai pengolah data dan LCD untuk menampilkan data. Pada penelitian ini didapat hasil perbandingan sensor DHT11 dengan alat ukur Thermo-Hygro yaitu rata-rata error suhu 0,75℃ dan kelembapan 3%. Hasil pengujian empat unit sensor DHT11 di luar ruangan didapat nilai rata-rata suhu sebesar 28,94℃ dan kelembapan sebesar 59,6% dengan jarak jangkau Xbee mencapai 240 meter, sedangkan nilai rata-rata suhu dan kelembapan hasil pengujian di dalam ruangan yaitu 29,14℃ dan 58,86% dengan jarak jangkau Xbee mencapai 70 meter

PORTAL MUI ONLINE: OPTIMALISASI DAKWAH ISLAM MELALUI INTERNET (Studi Kasus MUI Kecamatan Ujungberung)

Dakwah dan teknologi adalah sesuatu yang tak dapat dipisahkan. Ini jika kita berpijak pada konsep dakwah kontemporer yang mudah diterima oleh kalangan masa kini. Teknologi bukanlah sesuatu yang dilarang, meskipun dimasa Rasulullah SAW belum ditemukan adanya teknologi seperti yang berkembang pesat sedewasa ini. Di satu sisi, MUI (Majelis Ulama Indonesia) berkewajiban menyampaikan syiar Islam kepada umat secara berkelanjutan dan dilakukan kapan saja, di sisi lain, ia juga harus melakukan pengelolaan organisasi dengan dukungan teknologi. Berdasarkan hal tersebut, penelitian yang telah dilakukan merupakan penelitian rekayasa perangkat lunak yang bertujuan membangun aplikasi Portal MUI Online yang dapat membantu Syiar Islam dan optimalisasi pengelolaan organisasi MUI di Kecamatan Ujungberung. Penelitian dilakukan dengan pendekatan model inkremental untuk membagi tahapan secara modular. Alat bantu pemodelan menggunakan Unified Modeling Language (UML), dan tolls pengembangan menggunakan PHP5 dan MySQL untuk manajemen database-nya. Hasil penelitian berupa prototipe sistem, yang sudah diuji secara blackbox dan whitebox, menunjukan keberjalanan sistem dengan baik

IoT-Based UPS monitoring system using MQTT protocols

Uninterruptible power supply (UPS) monitoring system using message queuing telemetry transport (MQTT) protocol is a solution to solve UPS monitoring issues in a large infrastructure. This paper discusses the proof of the small size of message data by using the MQTT protocol on IoT-based communications. Based on IoT concept, the system described in this paper used Arduino microcontroller connected to the Internet via an Ethernet shield. The system used MQTT as a communication protocol that was designed for a lightweight communication. This system was intended to display UPS monitoring data in real-time on a web page stored on raspberry pi which roles as a web server, MQTT broker, MQTT subscriber and database. UPS parameter could be monitored using a web-based application. There were some differences in data obtained from sensor with the measurement results of measuring instruments specified for each parameter: the difference of input voltage was equal to 0.20%, while differences of output voltage, output power and output current reached 1.34%, 0.17% and 20%, respectively

Wideband substrate-integrated-waveguide BPF incorporated with complimentary-split-ring-resonators

This paper discusses the development and characterization of wideband substrate-integrated-waveguide (SIW) bandpass filter (BPF) incorporated with two reversely arrangedcomplimentary-split-ring-resonators (CSRRs). The proposed filter is intended to have band-width response more than 8 GHz suitable for applications in wireless communication systems.The incorporation of CSRRs on the SIW surface allows the extension of passband area at thehigher frequency region yielding the wideband response of filter. A 1.6 mm thick FR4 epoxydielectric substrate with the dimension of 40 mm×45 mm is applied for filter implementation.The characterization result shows that the proposed filter has the fractional bandwidth of around135% at the center frequency of 6.74 GHz. This result was achieved through measurement setupto demonstrate a good agreement between the simulation and experimentation
