Network Research (1/4) Network Visualization and Management

“Collecting inside information to visualize network status”by Dai Mochinaga (Mitsubishi Research Institute Inc.)

“The personalized measurement service in perfSONAR”by Abay Wo (NCHC)

“Experiment of deploying perfSONAR at SC08”by Yasuichi Kitamura (NICT)

“The advanced implementation of network management system with fault detection in TWAREN hybrid network”by Ming-Chang Liang (NCHC)

Collecting inside information to visualize network status

SNMP obtains information from nodes one by one. Disclosing information leads to improved End-to-

End visibility i-Path

Offering end-to-end visibility Observing privacy Respecting disclosure policy

7

The personalized measurement service in perfSONAR

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

Experiment of deploying perfSONAR at SC08

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.

The advanced implementation of network management system with fault detection in TWAREN

hybrid network

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 fault detection method

Dynamic threshold calculation method Automatic trend detection method

Network Research (2/4) Network Control

“The Design Motivation and Objectives for Fast Congestion Notification (FN)”by Mohammed M. Kadhum (Universiti Utara Malaysia)

“Networking Performance Evaluation for Multimedia Sharing among Networked Tiled Display Nodes”by Vinay Ramachandra (Gwangju Institute of Science and Technology)

“Service Provisioning in terms of Performance for IPv6 Based Communication”by Raja Kumar M (Universiti Sains Malaysia)

“Utilization and Performance Analysis of SIP6”by Cansheng Fan (Tsinghua University)

11

The Design Motivation and Objectives for Fast Congestion Notification (FN)

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

Networking Performance Evaluation for Multimedia Sharing among Networked Tiled

Display Nodes Multi-display monitors are

arranged in tile fashion We compare the networking

performance of selectedtransported 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

Service Provisioning in terms of Performance for IPv6 Based

Communication 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

Utilization and Performance Analysis of SIP6

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.

SIP6 :IPv6 based SIP platform This paper analyses the utilization and performance of SIP6

user distribution, IPv6 address distribution, and platform performance

Although the registration of new users keeps growing, the online users grow much slower

Invalid registration and users lost every day

Network Research (3/4) Wireless Communications

“Frame aggregations in the wireless LANs : A review paper”by Anwar Saif (University Putra Malaysia)

“A Proposal of Green Wireless LAN System Based on Dynamic Power Supply Control”by Ryo Nakamura (Kyushu University)

“Development Of IPv6 Network With Location Assisted Transfer For Real Time Applications”Nur Haliza Abdul Wahab (Universiti Teknologi Malaysia)

16

Frame aggregations in the wireless LANs : A review paper

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

17

A Proposal of Green Wireless LAN System Based on Dynamic Power Supply Control

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.

Development Of IPv6 Network With Location Assisted Transfer For Real Time

Applications 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

Network Research (4/4) 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

An Efficient Clustering Algorithm with Transmission Range Extension for Wireless

Sensor Networks 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

An Adaptive Energy-efficient Multi-hop MAC Protocol for Sensor Networks

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.

Experiment of high-performance data transfer between ITER and Japan

To support data intensive computational science, we have proposed and offered data transfer system in long distance

We aim to achieve high performance and friendly data transfer. On a shared network (i.e. not a dedicated line), interference with other traffic must be avoided

Pacing is effective for Bandwidth bottleneck in the middle of the network Too small buffer sizes of the intermediate switches Friendliness with background traffic on shared line

SSD is suitable for data transfer over file system
