    Abstract
    The research discusses about the process of sending video package in real time on WLAN (Wireless Local Area Network). To process the sending of video package, the transport layer of the UDP (User Datagram Protocol) is used, and compared the video transmission process in real time with mathematical model for video traffic, namely Two-State Markov model and Decodable Rate model because the rate of bytes is changeable. In order to analyze the video transmission performance accurately, 802.11 network is modeled by the Bianchi model. The result of the research showed that the number of users influenced the quality of sending video package to server either delayed or the number of packet lost. The Decodable Frame Rate was influenced by the packet loss value obtained when the experiment was done. The bigger value of the packet loss was, the smaller number of the Decodable Frame was. The difference between the experimental process and the Decodable Model for the Akiyo Video Trace GOP 24 (The Group of Pictures 24) was 0.176 and Akiyo Video GOP 40 was 0.094.
     
    Penelitian ini membahas proses pengiriman paket video secara realtime pada jaringan WLAN, untuk proses pengiriman paket video ini menggunakan transport layer protokol UDP dan membandingkan proses transmisi video secara realtime dengan pemodelan matematis untuk trafik video yakni model Two state markov dan model Decodable rate, karena laju kedatangan byte yang berubah-ubah agar kinerja transmisi video dapat dianalisis secara lebih akurat, jaringan 802.11 dimodelkan dengan Bianchi model. Hasil dari penelitian jumlah user mempengaruhui kualitas pengiriman paket video ke server baik delay maupun jumlah packet loss. Decodable frame rate dipengaruhi oleh nilai packet loss yang diperoleh ketika percobaan dilakukan. Semakin besar nilai packet loss, maka jumlah frame yang decodable juga akan semakin kecil. Selisih perbandingan proses eksperimental dan model decodable untuk trace video akiyo GOP 24 0,176 dan video akiyo GOP 40 0,094
