Probing Packets Efficiency and Effectiveness on Network Performance and Measurements

چکیده
Quality of Service (QoS) has become more widely recognized as an important issue since network applications with real-time requirements have started to spread on a larger scale. Measuring QoS in the internet today is difficult as notions of what constitutes QoS vary. Additionally, service Level Agreements (SLA) between customers and network service providers are often poorly defined. Therefore, all the information needed to infer the network performance must be monitored in order to extract the network QoS parameters: latency, jitter, packet loss and throughput. This paper presents a direct estimation of active one-way delay, throughput, and losses measurements precision compared to the actual user measurements. This evaluation allows us to objectively evaluate the network applications performance for delivering user acceptable quality.

An Insight into the Model Structures Applied in DEA-Based Bank Branch Efficiency Measurements
In this paper, we focus on the Data Envelopment Analysis (DEA)-based model structures have been used in assessing bank branch efficiency. Probing the methodologies of 75 published studies at the branch level since 1985 to early 2015, we found that these models can be divided into four categories: standard basic DEA models, single level and multi-level models, enriched (hybrid) models and specia...
متن کاملDesign of a Low-Latency Router Based on Virtual Output Queuing and Bypass Channels for Wireless Network-on-Chip
Wireless network-on-chip (WiNoC) is considered as a novel approach for designing future multi-core systems. In WiNoCs, wireless routers (WRs) utilize high-bandwidth wireless links to reduce the transmission delay between the long distance nodes. When the network traffic loads increase, a large number of packets will be sent into the wired and wireless links and can...

Mobile ad hoc networks are networks composed of wireless devices to create a network with the ability for self-organization. These networks are designed as a new generation of computer networks to satisfy some specific requirements and with features different from wired networks. These networks have no fixed communication infrastructure and for communication with other nodes the intermediate no...
متن کاملAn inference routing tree topology algorithm for reducing overhead in packet probing
Network structure (Topology) and Node dynamics (Links) are essential components of a secure robust network monitoring and application design. Packet probing is an important network measurement technique, used to understand packet delays, paths, and loss. In this paper we propose an RNJ(Route Neighbor Joining) algorithm which is a grouping type algorithm that recovers the tree topology by recurs...
متن کاملThroughput Analysis of End-to-End Measurement-Based Admission Control in IP
This paper introduces approximate analytical models to evaluate the performance of End-to-end Measurement Based connection Admission Control (EMBAC) mechanisms, devised for the setup of real time flows over the Internet. These mechanisms rely on users probing the current congestion status of their required network path using a succession of probing packets. If the probing rate measured at the e...
