Title: "Detecting abusive traffic flows in very high-speed
networks"
Author: Tetsuya Mori (Waseda Univ)
Summary:
In
a network link with sufficient volume of traffic, a small number of abusive
traffic
flows
constructed from a large number of packets occupy a large part of whole
aggregated
traffic.
Here, traffic flows can be defined by different level of granularities; i.e.,
pairs of end-hosts,
network
prefixes, and ASes. Detecting abusive traffic flows in
various levels of granularities will
be
useful for constructing efficient and effective traffic engineering schemes.
However, in very
high-speed
networks, keeping all per-flow states for detecting particular flows is a
challenging
task.
In this work, we propose two new methods for detecting such flows efficiently.
The core
idea
of our approach is to utilize a priori / learned information of flow statistics.
We further validate
and evaluate our
approach using measured packet traces.

2. Title: "A new method for
traffic matrix estimation "
Author: Susumu
Shimozu (Waseda Univ), Shigeki Goto (Waseda Univ)
Summary:
This
presentation introduces a new method for estimating real-time traffic
matrices with
small
estimation errors. A traffic matrix
represents flows of traffic in a network. It is an essential
tool
for capacity planning and traffic
engineering. However, measurement
costs and
computational
complexity
make it difficult to calculate an
accurate traffic matrix.
There have been other
approaches which have used IP-related information to reduce the
estimation
error
and computational complexity. In contrast, our method, called spike flow
measurement (SFM)
reduces
the error and complexity by focusing on spikes. A spike is transient excessive
usage of a
communications
link. Spikes are easily monitored through SNMP
framework. This reduces
measurement
costs compared to that of other approaches.
From traffic byte counts,
SFM identifies spike flows by detecting pairs of incoming and outgoing
spikes
in
a network. Then, we build a matrix from collected spike
flows as an approximation of the
real
traffic
matrix. Our experimental evaluation
showed that the average estimation
error is 20%, which
is
small enough for the method to be
applicable to a wide range of network nodes, including Ethernet
switches
and IP routers. Now we are
conducting an experiment in Waseda's campus network core.
Results
of the experiment will be also
discussed.

By way of QGPOP, KJCN,
APII, and KOREN, we established big broadband network from
developed in
June 2004. As of the end of August 2004, 18 events were performed, including 8
live
surgical demonstrations and 10 teleconferences. They started with endoscopic surgery and
neurosurgery,
extending their fields to transplantation, robotic surgery and telepathology.
We used 1or 2 DVTS lines. Time delay was 0.3 sec between both ends of the
network, which was
comfortable for
communication. High quality moving images were also preserved, but noise or
sound
loss was
frequently observed, which need to be further improved. Patient privacy was
protected with
a
security program but it should be more easily and widely
available.
Our medical network is
planned to be connected to

(intraductal ultrasonography)
in diagnosis of pancreatobiliary diseases with
application of 3-D
reconstruction image"
Author:
Hiroyuki Konomi (Department of Surgery and
Summary:
Computer tomography (CT)
and magnetic resonance image (MRI) have been made significant
contributions in diagnosis of hepatobiliary diseases. This is mainly because these methods
have a
high density-gradient resolution as well as a
reasonable spatial resolution. ERCP is the most essential
methods to approach pancreatobiliary region by directly injecting contrast
medium into the pancreatic
and/or bile duct. Rational spatial resolution of ERCP in
the pancreatic and/or bile duct is much higher
than those of CT or MRI because it is a direct
visualized image. However it is
still difficult to detect a
small tumor in the pancreas parenchyma as far as the
tumor does not affect pancreatic duct system.
This is why we need alternative
high-resolution diagnostic methods combined with ERCP technique.
Intraductal
ultrasonography (IDUS) may be one candidate to resolve
these issues, because it must
have rationally very high resolution by high
frequency ultrasound (i.e. over 20 MHz).
Moreover, 3-D
reconstruction system combined with color Doppler blood flow
meter for IDUS has recently developed,
however there are still various problems regarding ERCP
and IDUS that may be resolved by virtual
reality techniques.
New imaging system and the
problems what we are not achieved at this stage will be
presented.

"Applying
a new TCP Protocol Machine to Mobile IPv6"
¡¡¡¡Author: Heshmatollah
KHOSRAVI (
¡¡¡¡Summary: This
paper proposes a new TCP protocol machine, which monitors the
network
by flow analysis. It is a multipurpose tool. It can be used for intrusion
detection
and congestion observation. It is
used for mobile hosts as well as wired
and
stationary hosts.
In
mobile IP, the source and destination IP addresses changes during the life
of
a communication. In mobile networks, a mobile host carries two IP addresses
while
moving among networks. When we
apply the TCP protocol machine to
mobile
networks, there are two problems. This paper investigates these problems
and
proposes a solution.
TCP
protocol machine receives a sequence of TCP packets as input and classifies
them
into flows. A flow is a sequence of
packets, which has the same source and
destination
IP addresses, and port numbers.
Mobile IP allows a mobile node to move
among
networks while keeping all of its connections. When a mobile node is located
in
a foreign link, it uses two IP addresses, the home address and the care of
address
(CoA). If
the CoA is used, a TCP protocol machine generates a
wrong
classification
of flows. This is the first
problem.
The
second problem is related to the timeout. In a TCP protocol machine, timeout
is
defined to be equal to MSL (maximum segment lifetime) of TCP protocol. If there
are
two packets with the same IP address and port numbers, and the time interval
between
them is more than the timeout, then they are classified into two different
flows. If we apply the same timeout to mobile
nodes it will causes a problem. A
TCP
protocol
machine may classify the packets into one flow.
This
paper proposes a solution in a new TCP protocol machine. We propose a
pre-processor
to look into the encapsulated packets in mobile IP. This solves the
problem
in IP addresses. This paper also
suggests to solve the timeout problem.
We
propose two methods. One method is
to increase the value of the timeout.
The
other method improves the protocol in mobile IP to make a fast transition by
reducing
the registration time.

¡¡¡¡Summary: One
of a major design flaw of IPv6 protocol suites is that¡¡it makes Neighbor
Discovery
a defact standard adaptation mechanism between IPv6
and various link
layer
protocols, even though IP should work over various link layer protocols,
adaptation

A
consequence is that Neighbor Discovery is not applicable to WLAN, one of the

Summary:
Recently, two novel methods for
enteroscopyhave been developed, one
being double-balloon method and the
other capsule endoscopy. Double-balloon
method is characterized by attached
to the tip of the endoscope and the
other at the distal end of an overtube. By reciprocal insufflation of the using
these balloons, the endoscope can be
inserted further, without forming
redundant loops, into the distal small
intestine. Capsule endoscopy is a
small wireless endoscope. It can
take two pictures per seconds for eight hours.
This method allows painless and
patients can access to daily life
during
examination. We applied both methods to
patients with obscure GI bleeding
and Peutze-Jeghers suydrome. Both
methods can identify GI bleeding source
and polyps. We were able to treat
GI bleeding source by double-balloon
method. CONCLUSIONS: Double-balloon method and
capsule endoscopy
are promissing procedure
for the diagnosis of small intestinal pathology.

Recently, two
major IX architectures exist. One uses LAN (Local Area Network)technologies
such as
FDDI, Ethernet or Gigabit Ethernet to interconnect ISPs to each other. The other
IX
architecture is
based on ATM (Asynchronous Transfer Mode) technology,which uses PVCs
(Permanent
Virtual Circuit) between participating ISPs. We designed
and developed a new IX
architecture
using MPLS (Multi-Protocol Label Switching) technology.
We
apply this MPLS technology to an IX.A MPLS based IX has the advantages of the
independency
of
data-link mediums, unliminted bandwidth, scalability,

teaching materials for students at the class. It is also
important for teachers to
confirm the current status of learning progress of
students as easily as

It is easy even
for IT novice teachers
to use the system and it provides many useful and
straightforward facilities to
prepare each problems and compose examinations.
We can use it for
two type of examinations such as one of specifying a start and
end time for a
simultaneous examination and the other of specifying duration time
for
self-checking.
The system consists
of free or very cheap software and hardware with Web
user interface. It has a high performance as one note PC
can process more than
50 clients for
an simultaneous examination. It also can be operated only with one
CD by KNOPPIX
technology. We describe the design and

Understanding TCP over TCP: Effects of TCP Tunneling on End-to-End
TCP
Performance"
Author: Osamu
Honda, Hiroyuki Ohsaki, Makoto Imase (
Junichi
Murayama (NTT)
Summary:
TCP tunnel is a technology that aggregates and transfers packets
sent
between end hosts as a single TCP connection. By using a TCP tunnel,
the
fairness among aggregate flows can be improved and several protocols
can
be transparently transmitted through a firewall. However, since most
applications
running on end hosts generally use TCP, two TCP congestion
controls
(i.e., end-to-end TCP and tunnel TCP) operate simultaneously and
interfere
each other. Under certain conditions, it has been known that using
a
TCP tunnel severely degrades the end-to-end TCP performance. On the
contrary,
under other conditions, it has been known that using a TCP tunnel
significantly
improves the end-to-end TCP performance.
However, it is still
an
open issue --- how, when, and why is TCP tunnel malicious for end-to-end
TCP
performance? In this paper, we therefore investigate
effect of TCP
tunnel
on end-to-end TCP performance using simulation experiments.
Specifically,
we quantitatively reveal effects of several factors (e.g., the
propagation
delay, the bottleneck link bandwidth, the number of TCP flows
aggregated
in a TCP tunnel, usage of SACK option, TCP socket buffer size,
MTU
(Maximum Transmission Unit)) on performances of end-to-end TCP
and
tunnel TCP.

Summary:
Video streaming on P2P networks has received much attention in

continuous
P2P video streaming on a hierarchically-structured physical
network
such as an enterprise network. Our scheme constructs a
hierarchical
distribution tree among peers. Only the highest-level tree is
managed
by a centric server and lower-level trees are constructed
through
local communications among peers. Peers recover from faults by
themselves
for continuous video streaming on a dynamically changing P2P
network.
Through simulation and practical experiments, we verified that
our
scheme can provide low-delay and continuous video streaming for
thousands
or ten thousands of users on an unreliable P2P network.

"Adaptive
haptic synchronization for distributed virtual
environments"
Author: JongWon
Kim (GIST,
Summary:
Haptic-based
cooperative virtual environments are potentially
beneficial
in such areas as virtual surgical simulator, multi-hand
manipulation
system, and others. However, since
existing practical
IP-based
networks are suffering from packet delay (and jitter) and loss,
the
output quality of haptic media that requires upto kHz-range interactive
controls
is degrading severely. Thus, we need to adopt an adaptive
synchronization
control scheme for haptic media so that it can
maintain the
rendered
quality consistently to all participating users. In this regard, we
have
recently undertaken an initial effort to synchronize haptic-based
interactions
for the distributed virtual environment (DVE) over existing
practical
IP-based networks. By monitoring the underlying networks and
the
node systems, we are adaptively predicting the allowable time margin
of
each participating node in delaying the playout to
achieve the required
synchronization.
Then, each node will be asked to meet the target playout
delay
by adopting adaptive bucket-based synchronization and by intelligently
compensating
part of the delay with dead reckoning based on current
position
/ orientation / feedback force.

Summary:
We present multi-modal interaction for a
virtual dental simulation
which
allows dental students to train dental procedures through multi-modal
interface
including realistic haptic sensation. In addition, the
system supports
a
collaborative dental session between multi-users at remote sites.To
implement
this system, it requires haptic rendering and model
deformation
techniques
on¡¡the virtual tooth being deformed and sharing haptic
interaction.
We
enhance previous volume-based haptic modeling systems.
Collision
detection
and force computation are implemented on an offset surface
rather
than
the implicit surface to simulate physical interactions between the
virtual
dental
tool and tooth model. To bridge the gap between fast haptic process (1 KHz)
and
much slower visual update frequency (30Hz), the system generates
intermediateimplicit
surfaces between two consecutive physical models being
deformed
resulting in smooth force¡¡rendering. The volumetric tooth model
is
visualized as a geometric model which is adaptively polygonized¡¡according to
the
surface complexity. Volumetric material properties are used to simulate
the
resistance and¡¡texture information depending on anatomical tissues.
Finally,
we will describe our network structure for sharing¡¡haptic interaction

His research group has already proposed a prototype
system
called IntelligentBox. IntelligentBox is a component ware that provides
various
functionalities as 3D visible, reactive software components called

IntelligentBox also provides a dynamic construction
mechanism that
enables
users to construct various 3D graphics applications only by combining
already
existing boxes through direct manipulations on a computer screen.
IntelligentBox
has also provided a particular box called RoomBox that
allows
users
to build a collaborative 3D shared space easily and rapidly. Actually for
building
immersive collaborative environments, we need to employ devices
frequently
used for VR (virtual reality) applications. For this, the speaker has
introduced
particular software components, which manage such devices, into
IntelligentBox.
However, to provide practical collaborative environments, we
have
to employ Haptic devices, e.g., force-feedback
joystick, CyberTouch,
Phantom,
etc. because manipulations generate any feedback like the force
are
strongly required. In this talk, the speaker will introduce software
components
of IntelligentBox, those manages haptic devices, and will explain

real
object with the virtual object, and the interaction share to the virtual object
among

a haptic-based network handshake which enables us to

device and video conferencing.
Second,
we present a networked AR system that supports augmentation of remote
real
object with local virtual object using ARToolKit and
video streaming technique.
This
makes AR system be possible with the situation that real object does not exist
local
area. Third, we propose a networked interaction with AR that supports the
share
of interactions to the virtual object that is augmented to the real object
using
AR technique. This concept provides interaction to virtual object at any
aprticipants
and supports the share of the interaction result with all the participants
in
the network. The AR and network interaction concepts are integrated and

¡½Perspectives from Experiments and Experiences in Kyushu University Library¡½"
Author: Toshiro Minami¡¡(Kyushu
University), Takuya Kida, Setsuo Arikawa
Summary:
Automation is
very important for libraries in two aspects; cost reduction and advanced
services.
Kyushu
University Chikushi Library has recently introduced
RFID (Radio Frequency Identification)
system and ASRS
(Automated Storage and Retrieval System). RFID system will reduce the
librarians¡Ç
time for
processing borrowing/returning of materials. The inventory time is also
remarkably reduced
in comparison
with that of barcode. By using ASRS, the access time decreases to about a couple
of
minutes and the
necessary space for storing materials are also remarkably decreased. The aim and
effect of
introducing such systems are not only on reducing costs but also on collecting
useful data
for better
services. By introducing RFID system, for example, (i)
patrons are able to borrow books
by themselves
with satisfaction, (ii) the security gate can detect not only existence of books
that
are not properly
processed but also their IDs, (iii) a shelf equipped with an RFID tag reader can
detect which books
are about taken out and when, so that libraries are able to collect data about
usage of books
inside of the libraries. In our
presentation we will take some examples and search
for a perspective
on potential usefulness of such systems for advanced library
services.

"Exhaustive Experiment of Pattern
Discovery by Alternation Counts"
Author:
Yasuhiro
Yamada (Department of Informatics,
University Library), Sung Hyon Myaeng
(
Summary:
Pattern
discovery from structured or semi-structured documents is one of significant
tasks
of
Web mining. Online news articles and HTML pages returned from search engines are
typical
ones
written with templates. In this presentation, given documents with the same
template, we
consider
identification of the template. Assuming that substrings in a template appear
frequently,
the
key of pattern discovery is discovering frequent substrings in the
template.
We
have proposed a pattern discovery algorithm which uses the percentage `a' to
determine the
frequency
of substrings with length `n' and outputs the pair (n, a) which attains a local
minimum
alternation
count. An alternation count with respect to (n, a) is the number of boundaries
between
frequent
parts and infrequent parts. Substrings specified by the output (n, a) construct
a template
on
input documents.
For
empirical evaluation, we used 2,022 HTML/XML documents from 30 sites. We
calculate
experimentally
recalls and precisions of template detection for all (n, a) with n <= 50 and
a <= 100.
It
turned out that the algorithm yields (n,a) of high recall and precision, however, that the
algorithm
does
not always yield the best ones. We report possible improvement and a new
algorithm.

"Design of
a Query Language for Information Retrieval on Semantic Web Services"
Author:
Ha-Young
Yang, Jeong-Mok Yoo, Mann-Ho
Lee
Summary:
We design the architecture of a system for the
retrieval of cultural heritage information in the
semantic web service environment. The OWL-QL is chosen
as a query language for our system
because it can provide a relevance feedback that is
needed to our user interface design. The
OWL-QL uses a server continuation concept for
the Query-Answering Dialog that enables users to
communicate with agents and satisfies most of our
requirements on a query language. We extend the
XML schema which is originally defined by
Stanford University for the OWL-QL, and our user
interface is designed based on the extended schema. The
extension includes the modification of the
<premise> element
of the schema so that it can explicitly represent conjunctive and disjunctive
relations between triples. By this modification, users
can get some result sets from a query with the
uncertain facts. Moreover we add some more elements to
the schema to provide the detail information
about the result sets.

Testbed"
Author:
Tetsuya
Nakatoh, Yasuhiro Yamada,
Summary:
We
report an evaluation of a wrapper generation algorithm which discovers a
repetitive pattern
from
given search results. The repetitive pattern is expressed with token sequences
which consist
of
HTML tags, plain texts and wild-cards. In order to unify the variety of
instances of the same
pattern
in search results, the algorithm is based on {\em a
string matching algorithm with mismatches}
and
uses fast Fourier transform to recognize the pattern. We show an experimental
evaluation of
the
algorithm applied to 51 Web databases in the testbed
for information extraction.

"A prototype of automatic Web
syllabi integration system e-Learning"
Author: Eisuke Itoh¡¡Computing and Communications Center, Kyushu University),
Dou Yufeng,
Summary:
The authors are interesting in web
syllabi as an instance of web mining application. Although
a
syllabus only represents abstract of the course, however, comprehensively
collected and hierarchy
integrated
syllabi can be an effective educational and academic knowledge resource. Some
applications
using
integrated web syllabi are considerable. For example, textbooks ranking, and
terms extraction of
the
academic field are easy applications. Quality evaluation of schools is also
possible, because, the
syllabi
represents quality of education of the school, comparison of schools is
possible. It is possible to
construct
the academic ontology, if the syllabi are integrated in appropriate
hierarchy.
The authors implemented a prototype
of web syllabi integration system.
This system consists of
three
sub systems, web syllabus crawler, syllabus record extractor, and syllabus XML
integrator.
In
this presentation, the authors explain the outline of the system, and
demonstrate the system,
if
possible.
The authors also
discuss performance of the system.
The authors applied the system to integrate
Japanese
syllabi.
The system collects about 30 thousand possible web pages, extracts syllabus
record
from
about 100 sites, and integrates about 10 departments syllabi in XML
files.
