Multicasting
IP Multicast
– For video transmission efficiently
– Complex deployment (PIM, IGMP,MOSPF, etc.)
– Other issues:
• Not widely supported, scalability, security, group management
Overlay Multicast
– Known as application layer overlay multicast
– Unicast tunneling between server and agents
– Issues:
• Extra agents needed, long latency, group management
SDN technologies is necessary for multicasting

Software Defined Networking (SDN)
Allows network administrators to manage network services through abstraction of lower level functionality.
OpenFlow is an open standard and protocol of SDN
Open vSwitch (OVS) is a production quality, multilayer virtual switch
Software Defined Networking Open vSwitch

XIA: eXpressive Internet Architecture
An project from FIA (Future Internet Architecture) of NSF
GENI has been supporting XIA
– XIA has used GENI for demonstrations and wide-area experiments
It is conducive to future technologies experiments thru international collaboration on KOREN/TEIN
It's important to deploy and evaluate FIA on wide area networks.
FIA-NextPhase focuses on demonstrating the benefit through practical deployment.

QoE (Quality of User Experience)
QoE: Quality of User Experience
Definition:
– The overall acceptability of an application or service, as perceived subjectively by end-user
• From ITU-T P.10/G.100
Difference between QoS and QoE
– QoS : Objectively measure the quality of the service
– QoE : Subjectively measure the users’ sense of the quality of the service

Network Status Test results
–Jitter and packet loss test results based on UDP transmission using iperf
–Jitter and packet loss have much relationship with transmission data rate and available bandwidth.
–If the available bandwidth is much higher than UDP data rate, Jitter and packet loss are very slow.
–If the available bandwidth is lower than UDP data rate, Jitter and packet loss are high.

Network Status Analysis (KOREN KU & KAIST) –For the bandwidth
•The network has highest bandwidth in the whole day(94Mbps)
–For the delay
•Delay is almost the same in the whole day
–For the jitter and packet loss
•When transmitting 50M files, the jitter is 0 and packet loss is 0
•When transmitting 100M files, the jitter is 0.12ms and packet loss is 4.8%

Conclusion
SDN, ICN (XIA) and multicasting are emerging technologies topics in future networks
Network Status Test
–For international research network
•Best time bucket for test is around 7:00am-10:30 am
Construction of following testbeds will be carried out:
–QoS/QoE measurement and analysis of data transmission in APII/TEIN
• QoS/QoE based dynamic routing mechanisms
