Public Work

Local Area Network is currently often used to minimize a public work, different network segmentation in a building requires attention in designing a network that has dense traffic and often occurs down and vails over on a network flow, certainly requires performance optimal and efficient network, by way of network encapsulation with one channel and dividing each network segmentation by VLAN. The purpose of this paper is to apply a design by optimizing a network using the network redundancy method to create a more optimal network. This redundancy method is a method that moves a network path when downtime occurs on one of the routers that are automatically changed to an active router and a standby router. In the implementation of the design using GNS3 software to create network topology and design. With the results of tests that have been carried out using the simulator, packet loss from using the HSRP method is at VLAN10 0.11%, VLAN20 0.13%, VLAN30 0.30%, VLAN40 0.13%, VLAN50 0.22% AND VLAN60 0.16%. So the purpose of research makes a network more optimal and flexible

Unequal Loss Protection

Wireless local area network–based broadcasting techniques are a type of mobile Internet Protocol television technology that simultaneously transmits multimedia content to local users. Contrary to the existing wireless local area network–based multimedia transmission systems, which transmit multimedia data to users using unicast packets, a wireless local area network–based broadcasting system is able to transmit multimedia data to many users in a single broadcast packet. Consequently, network resources do not increase with the increase in the number of users. However, IEEE 802.11 does not provide a packet loss recovery algorithm for broadcast packet loss, which is unavoidable. Therefore, the forward error correction technique is required to address the issue of broadcast packet loss. The broadcast packet loss rate of a wireless local area network–based broadcasting system that transmits compressed multimedia data is not proportional to the quality deterioration of the received video signals; therefore, it is difficult to predict the quality of the received video while also considering the effect of broadcast packet loss. In this scenario, allocating equal forward error correction packets to compressed frames is not an effective method for recovering broadcast packet loss. Thus, several studies on unequal loss protection have been conducted. This study proposes an effective, prediction-based unequal loss protection algorithm that can be applied to wireless local area network–based broadcasting systems. The proposed unequal loss protection algorithm adopts a novel approach by adding forward error correction packets to every transmission frame while considering frame loss. This algorithm was used as a new metric to predict video quality deterioration, and an unequal loss protection structure was designed, implemented, and verified. The effectiveness of the quality deterioration model and the validity of the unequal loss protection algorithm were demonstrated through experiments.

Ambiguous Data

A lot of network management tasks require a description of the logical and physical computer network topology. Obtaining such a description in an automatic way is complicated due to the possibility of incompleteness and incorrectness of the initial data on the network structure. This article provides a study on the properties of incomplete initial data on network device connectivity on the link layer. Methods for generalized handling of the heterogeneous input data on the link layer are included. We describe models and methods for deriving a missing part of the data, as well as the condition in which it is possible to get a single correct network topology description. The article includes algorithms for building a link layer topology description from incomplete data when this data is possible to fulfill up to the required level. Also, we provide methods for detecting and resolving an ambiguity in the data and methods for improving incorrect initial data. Tests and evaluations provided in the article demonstrate the applicability and effectiveness of the build methods for discovering various heterogeneous real-life networks. Additionally, we show advantages of the provided methods over the previous analogs: our methods are able to derive up to 99\% data on link layer connectivity in polynomial time; able to provide a correct solution from an ambiguous data.

With the increase of internet user today, if it only has one router, when the router experiencing a network failure, then the internet cannot be used. To overcome this problem, the HSRP (Hot Standby Router Protocol) method by creating one active link and one backup link has been applied in the previous research. In this research will be applying the HSRP, VTP (Vlan Trunking Protocol), InterVLAN, and VLAN (Virtual Local Area Network) as a comparison. The testing parameter in this research will be using packet loss and throughput. From the result of testing that has been done, it shows that by applying the HSRP method, it gives a network availability with the packet loss of only 0,32%, and throughput of 1,159Mb/s (95,58%) from using 100 PC.

Jaringan komputer adalah jaringan penghubung komputer yang akan memberikan akses pada aplikasi layanan. Video Streaming merupakan layanan yang dapat mengkonsumsi bandwidth besar sehingga menyebabkan layanan akses lainnya tidak mendapatkan bandwidth yang cukup. Selain itu jaringan LAN sangat rentan sekali akan dimasuki oleh malware yang membuat jaringan sering down dan tidak stabil.Oleh karena itu, diperlukan adanya pengamanan jaringan dan filtering layanan. Dengan memanfaatkan router mikrotik dengan filtering port firewall dapat meminimalisir terjadinya penyebaran malware dan mengurangi penggunaan bandwidth. Metode Penelitiann yang dilakukan dengan studi literatur, perancangan, impelentasi, analisa pengujian. Hasil pengujian performansi sebelum implementasi filtering port pada jaringan LAN menunujukkan nilai bandwidth 98,04 Mbits, Jitter 0,046 ms, dan Packet loss 0,3 ms. Sedangkan pengujian nilai QoS setelah penerapan filtering port menunjukkan hasil bandwidth 364 Mbits, Jitter 0,022, dan packet loss 0,047. Performansi lebih stabil dan menunjukkan kinerja yang baik pada implementasi filteirng port video streaming. Hasil pengujian kenaikan dan penurunan nilai performansi masih dalam standart rekomendasii ITU-T.

Standar jaringan WLAN yang paling banyak beredar dipasaran saat ini adalah IEEE 802.11n. Untuk membangun jaringan WLAN yang lebih praktis dapat menggunakan teknik UR dan WDS.  Penelitian ini bertujuan untuk dapat mengukur dan menganalisa pengaruh jumlah client dan jarak terhadap kualitas jaringan WLAN yang menggunakan teknik UR dan WDS dengan parameter ukur bandwidth, jitter, dan packet loss. Hasil analisa data diketahui bahwa semakin banyak client dan semakin jauh jarak transmisi dapat menurunkan kualitas jaringan UR dan WDS. Kualitas jaringan terbaik dihasilkan jaringan UR pada jarak 7,5m dengan rata-rata bandwidth sebesar 11934.7035 Kbps, rata-rata jitter sebesar 2.3563135 ms, dan rata-rata packet loss sebesar 1.90% dibandingkan jaringan WDS dengan rata-rata bandwidth 3846.9135 Kbps, rata-rata jitter 9.496095 ms, dan rata-rata packet loss 5.23%. Kualitas jaringan terburuk dihasilkan jaringan WDS pada jarak 30m dengan rata-rata bandwidth sebesar 898.32735 Kbps, rata-rata jitter sebesar 37.32591 ms, dan rata-rata packet loss sebesar 47.10% dibandingkan jaringan UR dengan rata-rata bandwidth 8859.797 Kbps, rata-rata jitter 13.082195 ms, dan rata-rata packet loss 19.24%. Hasil keseluruhan pengukuran diketahui bahwa teknik UR lebih unggul dibandingkan WDS dalam membangun jaringan WLAN.   KATA KUNCI : WLAN (Wireless Local Area Network), UR (Universar Repeater), WDS (Wireless Distribution System), Bandwidth, Jitter, Packet Loss
