

To monitor the network performance, various
measurement techniques are developed.
However, all is too network administrator centric.


Users have no idea how their application will behave until
they actually use them.
Personalized Internet measurement service in
perfSONAR architecture

perfSONAR :web service-based infrastructure for collecting
and published network performance monitoring. It integrates
network measurement tools and archives. discovery,
authentication and authorization, data manipulation,
resource protection and topology.
8

In Japan, APAN-JP started the perfSONAR service
and SPARC started the perfSONAR service especially
for supporting the demonstrations at SC08.


SPARC developed the weather map for this demonstration.
perfSONAR could be sure to provide the monitoring
data without setting the special boxes or without
looking for the collaborators.

TWAREN (TaiWan Advanced Research and Education NEtwork)
is a hybrid network composed of several types of network service
including Layer1 (Light-Path), Layer2 (VLAN, MPLS-VPN and
VPLS-VPN), Layer3 (research networks peering and transit) and
Layer7 (SSL VPN)
ISSUE



The use of multiple protection and backup scheme has caused some problems.
The best way to solve the problem is to start the backup scheme before the
problems happen. => prediction scheme

11


In computer network, the goal is that obtain or provide the highest
performance at the lowest cost.
Controlling the congestion at the gateway leads to better performance
of the network.



TCP connection needs sooner congestion signal sending.
Congestion in packet switching networks is related to buffer overflow
event.
Fast Congestion Notification (FN)




Combined (aggregate) buffer arrival
rate control
Actual queue size control
Early congestion detection & notification based on prediction
Definition & treatment of congestion at different severity levels
12


Multi-display monitors are
arranged in tile fashion
We compare the networking
performance of selected
transported protocols:
TCP, parallel TCP, Reliable Blast UDP (RBUDP)



Parallel TCP creates multiple TCP connections and delivers
partitioned payload in parallel over these connections.
RBUDP eliminates TCP’s slow-start and congestion control
mechanisms
Between RBUDP and parallel TCP, parallel TCP provides better
performance for this case.
13


Need to enhance network performance to support bandwidth
intensive multimedia contents, interactive and real time
applications
We present and discuss on how the IPv6 header size can be
reduced using customized IPv6 header for LAN traffic

The header size reduction result in reduced bandwidth utilization,
improved latency and increase throughput
14


Network and applications of IPv6 have been widely deployed and
used around the world, but the real utilization is far from
research
In CNGI(China Next Generation Internet) project, SIP6 is one of
the key applications.


This paper analyses the utilization and performance of SIP6



The overhead consumes most of channel utilization time
compared to the actual payload
Frame aggregation techniques



They enhances the performance by packing multiple frames in one
large frame
They are proposed for the next generation networks and being
adopted by 802.11n drafts
benefits


lead to better throughput compared to short frame
reduce the overheads by using only few overheads for large number
of packets

Question & Answer




Q1) When many users concentrates an AP, it seems to be difficult to
turn off the AP. I think that the Power Saving Mode is more effective.
A1) In general, Power Saving Mode is a function for wireless mobile
station because an AP always keep watching the request from the
station. Therefore, by controlling the AP directly, we aim at the
power saving.
Q2) Advertised APs have some functions that causes turning off the
AP to be difficult. How about that?
A2) I have little idea about recent APs. So I will study about that.

This paper present the development of IPv6 network test bed
that supports location tracking system which is purely software
based with minimum hardware dependent.
The proposed location tracking will be based on Received Signal
Strength Indicator (RSSI)
A device switching can be done to switch session from one device
to another in order to provide roaming in an IPv6

Sensor Network

“An Efficient Clustering Algorithm with Transmission Range
Extension for Wireless Sensor Networks”
by Wibhada Naruephiphat (National Electronics and Computer
Technology Center)
“An Adaptive Energy-efficient Multi-hop MAC Protocol for
Sensor Networks”
by Kien Nguyen (The Graduate University for Advanced Studies)
20



Clustering algorithm is one of the energy-efficient techniques to
improve the network lifetime in wireless sensor networks.
We present Limiting member node Clustering(LmC) algorithm to
limit the number of member nodes
The simulation results show that the performances of clustering
algorithms improve when the transmission range of a base
station Is extended.
21


When there is no traffic in the network, multi-hop MAC wastes
energy by keeping the radios on during a long listen period.
This paper proposes the ARMAC(adaptive routing-enhanced
MAC) protocol, which can avoid such wastage.


In ARMAC, a node can adjust the duration of the listening period
according to the traffic road
The simulation results in, in comparison with RMAC, ARMAC
improves energy efficiency yet keeps the same end-to-end latency.
