....to 19 Aug 2000 Colo Utah NCSA BCNet Wash Fig. 1. Probability density of queuing delays of 5 paths packets of 500 milliseconds. The packets themselves are TypeP UDP packets of 40 bytes. The sender emits packets containing the GPS derived timestamp along with a sequence number. See RFC 2679 [33]. The destination node also has a GPS and records the one way delay and the time the packet was sent. Each probe s time of day is reported precise to 100 microseconds and each probe s delay is accurate to 50 microseconds. Data is gathered in sessions that last no longer than 24 hours. The ....

....network. This is only a qualitative validation, because the examined scenario was no more under control as a simulation with ns. We performed one way delay measurements over the 28 Mbps link connecting the internal LAN of our university to the Internet, following the recommendations of [23] and [24]. The average link utilization produced by incoming tra#c from the Internet was obtained with MRTG, a passive monitoring system widely used throughout the world [26] Our measurements consisted of sending a poisson stream of probe packets, at a rate of 20 probes per second, for a time interval of ....

....performance information and long term trends about many different geographical areas of the Internet. Surveyor is a measurement infrastructure that is being deployed at several sites around the world. Surveyor measures the performance of Internet paths using the IETF IPPM standardized metrics [10], 11] The project is also developing methodologies and tools to analyze the performance data off line. The National Internet Measurement Infrastructure (NIMI) 9] is a measurement architecture in which a collection of measurement hosts cooperatively measure the properties of Internet paths and ....

....QoS and the performance of networks are classified into two types: active and passive monitoring. Unfortunately, both types have drawbacks. They are briefly summarized as follows. a) Active measurement monitors QoS and the performance of a network by sending probe packets and monitoring them [6], 7] 22] There are various active methods to measure network performance such as available bandwidth [16] delay, loss, and to estimate their link by link performance [12] They monitor the QoS performance of the probe packet stream to determine the QoS performance of the user network ....

....actual characteristics of communication links on the Internet. A traffic study [2] of about 600 Internet paths reveals that 30 exhibits a major asymmetry [3] Therefore, in the presence of asymmetric paths, round trip measurements actually measure the performance of two distinct paths altogether [4] and one way measurements are necessary to measure these different entities separately. In recent years, GPS based measurement systems have been used to measure one way delays. In these measurement systems, either standardised protocols (developed by IETF IPPM Working Group [5] or proprietary ....
....measurement systems, either standardised protocols (developed by IETF IPPM Working Group [5] or proprietary protocols are used. For example, in Surveyor project [6] standardised protocols are used. The standardised performance measurement procedures metrics are described in RFC2330 [7] RFC2679 [4], and RFC2680 [8] In [9] we conducted performance measurements between a few Internet site using a proprietary protocol proposed by [10] The standard methods of measuring one way delay and delay variance in the Internet uses synchronous techniques which require clock synchronisation between ....

.... order for us to grasp the exact state of the Internet, which is asymmetric [1] 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 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. With measurement data obtained through active measurement, the network management can be performed effectively. For example, we can conjecture that ....
