The number of packets passing the GGSN provides a rough estimate of the number of contemporary active PDP-contexts within each block (in order to hide this information, we had to rescale the graphs in Figure 109 by an undisclosed factor) This is lower at night when most MSs are inactive Therefore, the penetration of scanning traf c is subject to a time-of-day effect, and is maximal at the peak-hour In the speci c case shown in Figure 109, we found that a small fraction of MSs responded to each packet with an ICMP port unreachable message, thus causing backscatter traf c in the uplink direction We remark that S1 was just one of several sequential scanning sources with patterns similar to Figure 109 that were observed in the traces Moreover, we also found that other sources were performing (pseudo-)random scanning for long periods (whole days).

The author would like to sincerely thank a number of colleagues for providing support in writing this book unless otherwise stated, all of them are with Nokia Siemens Networks: Ralph K hne (Univ T bingen, Germany), Frank-Uwe Andersen, Nadeem Akhtar (IIT u u Madras, India) and Ulrike Meyer (Univ Aachen, Germany) reviewed critically several chapters, gave constructive as well as most welcome advice, and were invaluable discussion partners Mirko Schramm helped me keep up-to-date with the latest developments in 3GPP SA2, G nther Horn and Ulrike Meyer clari ed the 3GPP work on security, Ralph K hne and Uwe u u F ll did the same with 3GPP charging issues, as did Ulrich Thomas with the UTRAN.

J rg o o Swetina (NEC) provided me with insight into the ongoing work on 3GPP SA1, Max Riegel answered my numerous questions on WiMAX, Hannes Tschofenig shared his expertise on security issues in the IETF, Andreas K psel supported me regarding IETF mobility protocols o and Pierre Lescuyer (Nortel Networks) explained radio interface issues A number of key ideas in this book were developed together with Robert Hancock and Eleanor Hepworth (Roke Manor Research, UK) in the course of our joint work on future Mobile Communication Networks Thanks go also to Georg Carle (Univ T bingen, Germany) who was crucial in the initial u process of formulating what this book would be about This book is based on a course which I taught at the Technical University of Berlin, Germany.

In this case, the visits to each address block are scattered across the whole scanning period instead of being concentrated into distinguishable spikes Hence, the rate of arriving probes is low and steady As a result, random scanning is considerably less invasive then sequential scanning from the perspective of the network infrastructure Micro-congestion The simplest explanation for the loss of scanning packets in A B is that the probe bursts were clipped after hitting the capacity limit of some internal resource, for example, a link or the CPU of some router To verify this hypothesis, we zoom into a sample scanning burst from S1 and extract a complete (K = 0) set of delay measurements in its neighbourhood We divide the A B delay samples into two groups: scanning packets, identi ed by the IP address of source S1, and other traf c ( ltered time series).

Thanks therefore go also to my students for their critical and curious questions which helped to improve both the book s concept and its technical accuracy Finally, I d like to thank my editors at Wiley Birgit Gruber, Richard Davies, Sarah Hinton and Sarah Tilley who supported the writing process, answered all of my queries and managed the production process seamlessly..

The delay samples for both groups are shown in the right graph of Figure 108 For each packet arriving at A at time tA and observed at B at time tB > tA , we mark a point of coordinates tA , tB tA Let us focus on the scanning time series: the delay pattern is consistent with the presence of a buffer that lls up rapidly (initial slope) and then remains persistently saturated (plateau) After the llup phase, most arriving packets are lost, while others gain access to the (almost) saturated buffer and experience an approximately constant delay equal to the buffer depletion time,.

Equations 6.33 and 6.34 give the magnetic and electric eld intensities, Hp and E p, at a point x in space due to an electric dipole, p, produced by a spherical charge distribution, (x ), at the origin. We see that E p has a radial component but Hp does not so we would call this radiation transverse magnetic (TMr ) because it is orthogonal to the radius vector in spherical coordinates. Equations 6.38 and 6.39 give the magnetic and electric eld intensities, Hm and E m, at a point x in space because of a magnetic dipole, m, produced by a spherical current distribution, J (x ), at the origin. We see that Hm has a radial component but E m does not so we would call this radiation transverse electric (TEr ) because it is orthogonal to the radius vector in spherical coordinates. We do not expect quadrupole, octapole, hexadecapole, or higher-order moments in problems associated with spherical conductors in uniform external elds.
