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

Future Internet Architectures (FIA)

Accessing named resources – not hosts

Scalable distribution through replication and caching

Good control of resolution/routing and access

XIA: eXpressive Internet Architecture

– A future network architecture that includes support for ICN

– Carnegie Mellon University

– Support evolution from IP network to ICN

– Leverages fallback for legacy networks

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

17

Unsatisfactory

ratio 0%~5% 5%~15% 15%~30% 30%~50% 50%~

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.
