“…The IETF's IP Performance Metrics (IPPM) Working Group suggested one-way metrics and architecture for one-way measurement [2]. Metrics are one-way delay, one-way packet loss, instantaneous packet delay variation, etc [3][4][5]. One-way measurement is a kind of active measurement, which injects measurement packets in a path to measure and observes how the packets are served.…”

Abstract. In this paper, we propose an architecture of measurement system which can measure IETF's IP Performance Metrics (IPPM) such as one-way delay, one-way packet loss and packet delay variation in the Internet. As the synchronization among measurement systems is very important in one-way delay measurement, we used the Global Positioning System (GPS) to synchronize the measurement systems and provided the precision up to one micro-second. To improve the accuracy of one-way delay measurement, the proposed system employs timestamps at the Ethernet frame level. We carried out measurements on the real Internet with the implemented system. It is seen that delay differs largely between path directions. Through these measurements, we present the need of one-way delay measurement.

“…Network measurement is part of the responsibilities of the network management system and hence how the management information is stored in the agents and retrieved by the manager has already been illustrated in the previous section [5]. When referring to measurement, the agent corresponds to the measurement device.…”

An application of improving the end-to-end packet loss estimation has been presented in this application oriented research paper along with the simulation results in Java environment. Measurement and estimation of packet loss characteristics are challenging due to the relatively rare occurrence and typically short duration of packet loss episodes. While active probe tools are commonly used to measure packet loss on end-to-end paths, there has been little analysis of the accuracy of these tools. The objective of our simulation study done in java language is to understand how to measure packet loss episodes accurately with end-to-end probes using software approach. The recent studies show that the standard Poissonmodulated end-to-end measurement of packet loss accuracy has to be improved. Thus, here, in this paper we demonstrate the application of the algorithm for packet loss measurement to overcome the deficiencies in standard Poisson-based tools. We also find the transfer rate during the simulation study. We evaluate the capabilities of our methodology by developing and implementing a prototype tool, called BADABING. These simulation experiments done in the java environment demonstrate the trade-offs between impact on the network and measurement accuracy. BADABING reports loss characteristics are far more accurately than traditional loss measurement tools. The simulation results shown in this research paper shows the efficiency of the method developed which can be further used for a number of wide range applications.

“…For example, in Fig. 1 the OEs in AS 1 and AS 2 measure the same parameters, such as One-Way Delay (OWD) [8] or One-Way Loss (OWL) [9], and react in the same manner due to their mirrored behavior. Therefore, either of them is able to independently decide if it should shift its outbound traffic or not.…”

Abstract. This paper proposes a novel and incremental approach to InterDomain QoS Routing. Our approach is to provide a completely distributed Overlay Architecture and a routing layer for dynamic QoS provisioning, and to use QoS extensions and Traffic Engineering capabilities of the underlying BGP layer for static QoS provisioning. Our focus is mainly on influencing how traffic is exchanged among non-directly connected multi-homed Autonomous Systems based on specific QoS parameters. We provide evidence supporting the feasibility of our approach by means of simulation.
