ABSTRAKSI: Seiring kemajuan teknologi informasi dan telekomunikasi, maka kebutuhan terhadap jaringan akan semakin meningkat. Internet diharapkan dapat mengakomodasi aplikasi-aplikasi dengan kecepatan data tinggi. Kualitas koneksi pada jaringan harus terpelihara, agar koneksi tidak terputus akibat meningkatnya kebutuhan bandwidth dan beban trafik.
Pada penjadwalan core stateless, CSFQ dapat mengurangi kompleksitas kinerja router, domain jaringan dibagi menjadi router edge dan router core. Router edge mengatur trafik per flow dan melabelkan informasi pada paket-paket untuk selanjutnya diteruskan ke dalam router core. Sedangkan pada router core, hanya memperbaharui label. Label dapat merupakan fungsi dari waktu kedatangan paket, kebutuhan bandwidth, timestamp dan panjang paket. Model trafik deterministik dengan referensi timestamp diusulkan untuk mengevaluasi parameter unjuk kerja jaringan core stateless.
Pada penelitian diperoleh, penambahan referensi timestamp pada model trafik deterministik untuk penjadwalan core stateless dapat menurunkan delay dan packet loss. Uji hipotesis untuk data berpasangan memberikan H1 diterima, artinya ada pengaruh terhadap delay menggunakan model trafik deterministik dengan referensi timestamp pada selang kepercayaan 95%.

Internet is expected to accommodate applications with high data speeds. The quality of connection in the network must be maintained, so that connections are not interrupted due to rising bandwidth requirements and traffic load.
At the core stateless scheduling, CSFQ can reduce the complexity of router performance, network domains are divided into edge routers and core routers. Edge routers manage traffic per flow and information labels on packages to further transmitted into the core router. While the core router, just update the label. Labels can be a function of packet arrival time, bandwidth requirements, timestamp and packet length. A deterministic traffic model with a reference timestamp parameter is proposed to evaluate the performance of stateless core network.
On the research was obtained, adding a reference timestamp on deterministic traffic model for core stateless scheduling can reduce delay and packet loss. Hypothesis test for paired data provide H1 accepted, meaning there is an influence to delay using deterministic traffic models with a reference timestamp at 95% confidence intervals.Keyword: Core Stateless Scheduling, Deterministic Traffic Model, Timestamp, Core Stateless Fair Queuing (CSFQ).
