....number of links. They pinged approximately 4,500 domains (1,428 in Europe) six times daily, seven days a week. Their measurement data was used to plot geographical maps with round trip delays shown as circles in di erent sizes re ecting the magnitudes of the round trip delays. 17 Mukherjee [31] sent groups of 10 ping packets periodically with a 1 minute interval between successive groups. Packets within a group were sent at regular 1 second intervals. Round trip delays were averaged over a group. The delay distribution was found best modelled by a constant plus gamma distribution. ....

....not repeat it here. 3 General Characteristics of Delay and Loss 3.1 Periodicity Internet trac has its cycles. In general, day time means heavier trac [44] 30] hence higher delay and loss rates. Similarly, weekend usually has less trac than weekdays. This has been mentioned in [21] 30] 23] [29]. 3.2 Correlation between Delay and Loss On a long time scale (say, every minute) the daily cycles of delay and loss matches well with each other [21] This result is intuitive because losses generally occur because of congestion, and congestion leads to higher delays. On a short time scale of ....

....in southern California) and the Internet. by which we mean primarily heartbeat frequency, although the priority given to HBM processes and to HBM network trac can also be cost issues) and denition of failure. Note that these variables can be varied on a per component basis. Previous research [2, 16, 3, 17] provides some relevant data. For example, in a 1992 study in which 32 byte packets were sent over a 128 Kb s transAtlantic link at regular intervals for extended periods, Bolot observes high loss rates (9 ) but notes that losses are essentially independent as long as probe trac accounts for less ....

....logging at Internet routers or Network Access Points (NAPs) requires increasing the load on systems that may already be very busy. As an alternative, end to end measurements are commonly used. A number of end to end measurements have been performed for round trip UDP delay and loss [1] 2] [3], route dynamics [4] as well as unidirectional and round trip TCP delay and loss [5] 6] These studies reveal interesting and often surprising Internet behavior and serve to reinforce the importance of Internet performance sampling. In this paper, we focus on measurement and analysis of UDP ....
