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. 9   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.

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   SIP6 :IPv6 based SIP platform 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 15  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   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  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. 18    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 19  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. 22         5:30wake up 8:00breakfast 9:00Opening Plenary 10:30 Backbone Committee 12:30 lunch 14:00 e-Culture 21:30 dinner 23:00 go to bed 23       10:30 GDLN (Global Development Learning Network) 11:05 IMPACT (International Multilateral Partnership Against Cyber Threats) by Jagdish Singh 11:40 TLPW (TransLight/PacificWave) by John Silvestar (PacificWave & USC) 11:55 TransPAC by Jim Williams (TransPAC & Indiana University) 12:08 Exploring new R&E network reach from Japan to South Asia, the Middle East and Africa by Kazunori Konishi (APAN-JP ) 12:15 TEIN3 Upgrade by David West (DANTE) 24    Coordinated by the World Bank, the Global Development Learning Network (GDLN) is a partnership of over 120 recognized global institutions (Affiliates) in over 80 countries that collaborates in the design of customized learning solutions for individuals and organizations working in development.
