The increase in web traffic and the development of network bandwidth that is relatively faster than the development of microprocessor technology today causes the one point server platform to be no longer sufficient to meet the scalability requirements of web server systems. Multiple server platforms are the answer. One known solution is cluster-based web server systems. In this study, a cluster-based web server system would be designed with the Never Queue algorithm and continued with testing the distribution of web workload on this system. The tests were carried out by generating HTTP workloads statically (with fast HTTP requests per fixed second) and dynamically (rapid HTTP requests per second that change or rise regularly) from the client to the web server system pool. Followed by analyzing data package traffic. In this study, the results of static testing with rapid HTTP requests per second which still showed that the Never Queue algorithm distributed HTTP requests to the web server system pool properly and got HTTP replies that tend to be stable at the HTTP average of 1031.8 replies/s. As for the rapid parameters of TCP connections, response times and errors increased with the rapid increasing HTTP requests generated. The average output was at 2,983 Mbps.
The increase of web traffic and the development of network bandwidth are relatively faster than the development of microprocessor technology. This causes one point server platform no longer adequate to meet the needs of system scalability web server. Thus, multiple server platforms are the answer. One solution that has been known is a cluster-based web server system. This paper designs and develops cluster based web server system with Never Queue Algorithm. The system is then tested with a web workload distribution testing. The testing is carried out by generating HTTP workloads statically (with fixed HTTP request rate) from the client to a web server system pool. The result shows that HTTP requests are well-distributed to web server system pool by Never Queue Algorithm. HTTP reply rate tends to be stable at average of 1,031.8 replies/s because the system is saturated, while TCP connection rate, response time, and error, tend to rise along with the rise of HTTP request rate. As for throughput, the average is 2.983 Mbps. Correlation between stability and the rise of error is, at the saturated point, bigger HTTP requests yield bigger errors. Intisari-Peningkatan lalu-lintas web dan perkembangan bandwidth jaringan yang relatif lebih cepat dari perkembangan teknologi mikroprosesor dewasa ini menyebabkan platform server satu titik tidak lagi memadai untuk memenuhi kebutuhan scalability sistem server web. Platform server jamak adalah jawabannya. Salah satu solusi yang telah dikenal adalah sistem server web berbasis cluster. Dalam makalah ini dilakukan rancang bangun sistem server web berbasis cluster dengan algoritme Never Queue dan dilanjutkan dengan pengujian distribusi beban kerja web pada sistem ini. Pengujian dilakukan dengan cara menghasilkan beban kerja HTTP secara statis (dengan pesat permintaan HTTP per detik yang tetap) dari klien ke pool sistem server web. Dalam makalah ini, hasil pengujian secara statis dengan pesat permintaan HTTP per detik yang tetap menunjukkan bahwa algoritme Never Queue mendistribusikan permintaan HTTP ke pool sistem server web dengan baik dan mendapatkan balasan HTTP yang cenderung stabil di rata-rata pesat balasan HTTP sebesar 1.031,8 replies/s karena sistem mencapai titik jenuh pelayanan. Sedangkan pada parameter pesat koneksi TCP, waktu tanggapan, dan galat terjadi kenaikan seiring dengan bertambahnya pesat permintaan HTTP yang dihasilkan. Adapun throughput rata-rata berada di angka 2,983 Mbps. Korelasi kestabilan layanan dengan kenaikan galat terjadi saat mencapai titik jenuh. Semakin besar permintaan HTTP, semakin besar galat yang terjadi.
