“…The PQ algorithm is used sorting, searching [15]and route planning in classifying packets. In classifying packets, some issues such as selection of priority packets still occur recursively (repetition) when the operation, that can cause next queue starvation [18]; [10], [20] and [7]. This is due to incoming packet (in the form of voice, video, and data) are sorted (classified) based on priority.…”

(voice, video and text); that can reduce recursive loop and starvation. After the incoming packet is classified, the packet will be sent to the packet buffering. In addition, to justify the research objective of the PQ improved algorithm will be compared against the algorithm existing PQ, which is found in the literature using metrics such as delay, packets drop and packet losses. This paper described about different execution long process in Priority (PQ) and our algorithm. Our Algorithm is to simplify process execution Algorithm that can cause starvation occurs in PQ algorithm.

“…More generally, for the approximating NPPQ system, a class 4 packet is assigned to class 4* with probability P(4,5,6) + P(4,6,5), to class 5* with probability P(5,4,6) + P (6,4,5), and to class 6* with probability P(5,6,4) + P (6,5,4). Analogous assignments are made for class 5 and class 6 packets.…”

“…Packet traffic can simply be handled on a First Come First Served (FCFS) basis. With a high enough bandwidth and under normal traffic conditions, this can be sufficient [3], [4], [5]. In priority queueing (PQ), higher priority real-time traffic (e.g., VoIP traffic) is transmitted before lower priority traffic (e.g., data traffic), with separate buffers for each class of traffic.…”

Low Latency Queueing (LLQ) is an Internet Protocol (IP) router discipline that is being used to ensure that performance-sensitive high priority traffic, such as voice and video, receive their high level of performance, while allowing less performance-sensitive traffic, such as e-mail or best-effort IP, to receive some portion of the bandwidth. In this paper, we develop a simple analytic approximation for the buffer latency (expected buffer delay) for each traffic class using the LLQ system. The approximation is validated via a simulation model.

“…Much similar research using simulations has been done in the area of VoIP's quality improvement; some of it is presented in the following literature: Mansour J. Karam & Fouad A. Tobagi, 2001, Velmurugan T. et al, 2009, and Fischer, M.J. et al, 2007 VoIP's quality improvement is a very popular research area, mostly focused on queuing aspects, and the problem of decreasing jitter influence as in our case. The hybrid queuing mechanism concept (except PQ-CBWFQ) is our original contribution, resulting from the research of the past three years.…”
